Childbearing SN3180 Childbearing Family Nursing Newborn (1) Kitty Wong 2018 1 Reading text Chapter 27-29 of Davidson, M., London, M. and Ladewig, P. (2016). Old’s Maternal-newborn nursing and women’s health across the lifespan (10th edition). Boston: Pearsons. 2 Learning Objectives After completion of this lecture, you should be able to: a. describe the changes of the followings that occurs during the newborn’s transition to extra-uterine life: – the respiratory and cardiovascular changes – the process of thermogenesis – the newborn’s gastrointestinal tract and liver – the newborn’s urinary system to maintain fluid and electrolyte balance – the immunologic responses of newborn b. Explain the conjugation and excretion of bilirubin in newborns c. identify the reasons that a newborn may develop physiological jaundice 3 Transition to extrauterine life • The neonatal period / newborn period – from Birth to the 28th DAY of life • Neonatal transition – The first 6 to 8 hours after birth • Transitional period between intrauterine and extrauterine existence – Physiological adaptation • Respiratory adaptation • Cardiovascular adaptation • Thermal adaptation • Urinary adaptation • Gastrointestinal adaptation • Hepatic adaptation • Immunologic adaptation – Behavioral adaptation which will be discussed in Newborn (2) • Period of reactivity • Sleep-wake pattern • State organization 5 Immediate adjustment • Respiratory adaptations • Cardiovascular adaptations 6 Stimulation to first inspiratory gasp • Chemical stimuli – A brief period of asphyxia after normal vaginal labor and birth – Triggered by slight elevation in carbon dioxide, decrease in pH and oxygen – Stimulate the aortic and carotid chemo-receptors to the respiratory center (medulla) • Thermal stimuli – Decrease in environmental temperature, warm environment and enter a relatively cooler atmosphere (37 ℃ to 21-23 ℃ ) – Sudden chilling of infant Cold stimulate skin nerve endings newborn responds with rhythmic respirations • Sensory stimuli – Tactile, auditory, visual stimuli – Joint movement proprioceptor stimulation to respiratory center sustain respirations. 7 Initiation to Breathing To maintain life, the lungs must function immediately after birth. It depends on: Reduction of surface tension of the fluid that filled the fetal lungs and alveoli 8 9 Initiation of respiration in the newborn Mechanical events & reabsorptive processes Chemical, thermal, mechanical, sensory stimuli Chest recoil Fluid reabsorption Negative intrathoracic pressure Activation of 1st breath Entry of Air Commencement of reduced alveolar surface tension Decrease in interstitial pressure Increase in pulmonary vascular volume Increase in lymph circulation Increase in alveolar PO2 Opening of pulmonary vessels Increase in pulmonary vascular flow Promotion of adequate oxygenation Source: Davidson, M., London, M. and Ladewig, P. (2016). Old’s Maternal-newborn nursing and women’s health across the lifespan (10th edition). Boston: Pearsons. P.652 10 Characteristics of newborn respiration Normal respiration • Normal respiration rate (RR): 30-60 breaths per minute • Abdomen’s movement synchronous with the chest movement • Nose breathers Abnormal respiration • 30/ minute ≤ RR or RR ≥60 breaths/ minute when infant at rest • Apnea/ apnoea: cessation of breathing > 20 sec • Retraction of ribs (increase use of intercostal muscles) • Cyanosis • Nasal flaring • Expiratory grunting 11 12 Circulatory system • The circulatory changes allow the blood to flow through the lungs • Due to pressure changes in lungs, heart, major vessels • Transition from fetal circulation to neonatal circulation https://www.youtube.com/watch?v=uwswhoKfkmM 13 Fetal circulation https://youtu.be/9O-i6k0mGrU Fetal circulation before birth 14 Newborn’s circulatory system https://youtu.be/DC_wlkRPzw0 (revision use: Fetal circulation right after birth) 15 Fetal and neonatal circulation System Fetal Neonatal Pulmonary blood Constricted with very little vessels blood flow; lungs not expanded Vasodilation and increased blood flow; lungs expanded; increased O2 stimulates vasodilation Systemic blood vessels Arterial pressure rises due to loss of placenta; Increased systemic blood volume and resistance Dilated with low resistance; blood mostly in placenta Ductus arteriosus Large with no tone; Blood flow from pulmonary artery to aorta Reversal of blood flow. Now from aorta to pulmonary artery because of increased left atrial pressure. Foramen ovale Increased pressure in left atrium attempts to reverse blood flow and shuts one-way valve. Patent with large blood flow from right atrium to left atrium 16 Changes in fetal circulation at birth Structure Before Birth After birth Umbilical vein Brings arterial blood to the heart Obliterated Becomes ‘round ligament’ of liver Umbilical arteries Bring arteriovenous blood to placenta Obliterated Becomes ligaments on anterior abdominal wall Ductus venosus Shunts arterial blood into Inferior vena cava Obliterated Becomes ligamentum venosum Ductus arteriosus Shunts arterial and some venous blood from the pulmonary artery to aorta Obliterated Becomes ligamentum arteriosum https://youtu.be/yT8-mSUvDw8 structure of Foramen ovale 17 Transitional circulation: Conversion from fetal to neonatal circulation (1) Initiation of respiration (Lungs expanded) Decreased pulmonary vascular resistance Increased PO2 level Increased pulmonary blood flow Increased pressure in left atrium Closure of foramen ovale Decreased right atrial pressure Source: Davidson, M., London, M. and Ladewig, P. (2016). Old’s Maternal-newborn nursing and women’s health across the lifespan (10th edition). Boston: Pearsons. P.653 18 Transitional circulation: Conversion from fetal to neonatal circulation (2) Initiation of respiration (Lungs expanded) Closure of ductus venosus Cessation of umbilical venous return Increased PO2 level Increase systemic vascular resistance Decreased systemic venous return Systemic resistance > Pulmonary Closure of ductus arteriosus Left-to-right shunt Pulmonary resistance < systemic Source: Davidson, M., London, M. and Ladewig, P. (2016). Old’s Maternal-newborn nursing and women’s health across the lifespan (10th edition). Boston: Pearsons. P.653 19 Newborn’s circulatory system https://youtu.be/DC_wlkRPzw0 Fetal circulation right after birth 20 The normal baby : Cardiovascular system • Heart rate : 110 – 160 beats per minute • Blood pressure : – 70 – 50 / 45 – 30 mmHg at birth – 90/50 mmHg at day 10 • Compare the BP in the arm & calf, which should be equal • Heart murmur – produced by turbulent blood flow – Atrial or ventricular septal defect – Reversible flow of blood through the ductus arteriosus during early neonatal period, functional murmur is occasionally heard http://www.paediatrics.co.uk/nicu/normal-ranges (show newborn’s heart rate) 21 Response of BP to changes in neonatal blood volume Transient birth asphyxia Rise BP (immediate post birth) Increase peripheral Blood volume Increase circulating Blood volume Decrease pulmonary vascular resistance Subsequent increases in combined ventricular output Fall in BP as blood shifts from periphery into lungs and water shifts into the interstitial space from the plasma Slowly rising BP 22 Thermoregulation Birthing room temperature : 21℃ vs Intrauterine temperature: 37.7℃ Several factors predispose the newborn to excessive heat loss:1. 2. 3. Large surface area in relation to body mass Thin layer of subcutaneous fat Heat production (thermogenesis) in newborn 23 3. Heat production (thermogenesis) in newborn Non-shivering thermogenesis (NST) – Stimulating cellular respiration – Use of brown adipose tissue to generate heat – Brown fat cells promote rapid metabolism, heat generation, heat transfer to the peripheral circulation Increase basal metabolic rate (increase glucose & oxygen consumption) 24 25 - Sites of brown fat Adrenals and kidneys Brown fat / brown adipose tissue Located around the back of neck, axillae, around the kidneys, adrenals, and sternum; between scapulae; and along the abdominal aorta It generates more heat than white subcutaneous fat It contains an abundant supply of blood vessels Blood passing through brown fat is warmed and carries heat to the rest of the body Between scapulae sternum 26 Mode of heat loss in the neonate Convection Conduction Radiation Evaporation 27 Heat loss from the body surface to the environment Mechanism Examples Convection The loss of heat from the warm body surface to the cooler ambient air currents Air-conditioned rooms Radiation Heat losses when heat transfers from the heated body surface to cooler surfaces and objects not in direct contract with the body The cool walls of a room or of an incubator Evaporation The loss of heat result in conversion of water into vapor Immediate after birth, the baby is wet with amniotic fluid / during baths Conduction The loss of heat to a cooler surface by direct skin contact Cold examination table, cold stethoscopes 28 29 Urinary adaptation • Functional deficiency in the kidney’s ability to, – concentrate urine – cope with conditions of fluid & electrolyte fluctuations eg. dehydration • ~ 200 – 300 mL / 24 hours by the end of the first week • Bladder empties involuntarily when stretched by a volume of 15 mL • The first voiding should occur within 24 hours • Day1-2: void 2 – 6 time/day, urine output of 15 ml /kg / day • The urine is colorless & odorless, specific gravity ~ 1.020 30 Gastrointestinal system (1) Digestion: – Able to digest proteins and simple carbohydrate – Deficient production of pancreatic amylase impaired utilization of complex carbohydrates – Deficient in pancreatic lipase difficulty in digestion of fat e.g. fat in cow’s milk Liver : immature – ↓the enzyme glucuronyl transferase affect the conjugation of bilirubin physiological jaundice – ↓prothrombin & coagulation factors – ↓liver store of glycogen 31 Gastrointestinal system (2) Stomach capacity: - around 90 ml (full term infant ~ 3.4 Kg) - Regurgitation is common – due to Immature migrating motor complex (MMC) Decreased lower esophageal sphincter pressure Delayed gastric emptying MMC refers to rapid peristaltic waves and simultaneous non-peristaltic waves occur along the entire intestine inbetween meals However, longer intestine in relating to the body size ↑surface area for absorption Avoid overfeed and B______ to prevent regurgitation ping ur Progressive changes in the stooling pattern indicating a functioning GI tract 32 Gastrointestinal adaptation (3) • Meconium • Transitional stools – Usually appear by 3rd day after initiation of feeding – Greenish brown to yellowish brown, thin, less sticky than meconium – May contain some milk curds • Milk stool: usually appear by the fourth day – Stool of infant fed with breast milk • Mustard color and consistency • sweet-sour smell • 4 or more stool daily – Formula-fed infant • Pale yellow to light brown stool, firmer in consistency • have a more offensive smell • one to two stools daily. – Infant’s first stool occurs within first 24 hours – Greenish black with a thick, sticky, tar like consistency – Consist of particles from amniotic fluid e.g. vernix, skin cells, hair, cells from intestinal tract, bile, intestinal secretions 33 Change in stool patterns of Newborns Meconium Transitional Stools 34 Newborn stool Meconium Transitional stool Breast milk stool 35 Formula-fed stool 36 Coagulation • Liver • Coagulation factors II, VII, IX, and X (synthesized in the liver) activated under the influence of vitamin K • Absence of normal flora • Injection of vitamin K as prophylactic for bleeding problems on the day of birth 37 Defense against infections 1. Skin & mucous membranes 2. Neutrophils, monocytes, eosinophils & lymphocytes 3. Three major immunoglobulins : – IgG: passive acquired via placenta during the third trimester, also from human milk – IgM: normally produced by fetus in utero, begin at 10 to 15 weeks’ gestation – IgA: present in colostrum, IgA begins to be produced by newborn in the intestinal mucosa ~ 4 weeks after birth 38 Neonatal Jaundice Newborn develops an unconjugated serum bilirubin ≥ 30 μmol/L (18mg/dL) Neonatal hyperbilirubinemia is very common in US Kernicterus is its complication Mortality (incidence of kernicterus): 0.4-2.7 cases per 100,000 births in North America and Europe, and ≥ 30% of infants died in developing countries 40 HbF: Fetal haemoglobin Hb A: Adult Hb http://www.childhealth-explanation.com/jaundice-in-newborns.html 41 42 Causes Physiological Jaundice: immature liver, caused so the job of conjugating and removing bilirubin is not done completely well. As the breakdown of red blood cells slows down, and the baby's liver matures, the jaundice rapidly disappears. Neonatal jaundice: healthy RBC can be destroyed by http://www.pathophys.org/neonatal-hyperbilirubinemia/ haemolysis. Polycytnemia: baby born with excess RBC. Cephalohaematoma Baby swallows blood during birth, absorbed in bloodstream. With excess blood from a blood clot will cause a rise in serum bilirubin. GDM Hypoxia after birth 43 44 Signs and symptoms • • • • • Jaundice: head, arms trunk and legs. If severe, jaundiced below knees and over the palms Ill looking Fever Poor feeding 45 Management of NNJ • Assessment • Observation • Treatment – Ensure adequate intake – Phototherapy – ± Intravenous immune globulin – ± Exchange transfusion 46 Assessment History of pregnancy and delivery: • Maternal illness (viral or other infection) • Maternal drug intake • Delayed cord clamping • Birth trauma with bruising ± fracture Postnatal history of newborn: • Loss of stool color • Breastfeeding • Greater than average BW loss • Signs and symptoms of hypothyroidism • Signs and symptoms of metabolic disease 47 Assessment 1. History taking (cont’d): - family history of NNJ, anaemia and splenectomy (hemolytic disorder) 2. Onset of NNJ : o o o o o Within 1st 24 hours: should be assumed as non-physiologic; Day 1-2: metabolic screening for galactosemia and congenital hypothyroidism; Day 3-4: physiologic NNJ D 4-7: breast milk jaundice D 3: Breastfeeding jaundice 3. Examine under good daylight: face, chest, hands and feet. 4. Take serum bilirubin, haemoglobin, (if necessary baby’s blood group and perform Coomb’s test.) 48 Assessment for NNJ • • • • • • Yellowing of skin: checked by jaundice meter, serum Bb Pallor, anaemic at birth source of haemolysis signs of infection Feeding & hydration Stool color 49 Management: Phototherapy 1. Explain to parents: a. Use of visible light for the treatment of hyperbilirubinemia in the newborn. b. Common therapy lowers the serum bilirubin level by transforming bilirubin into water-soluble isomers that can be eliminated without conjugation in the liver. c. The dose of phototherapy largely determines how quickly it works: is determined by the wavelength of the light, the intensity of the light (irradiance), the distance between the light and the infant, and the body surface area exposed to the light. 50 Management: Phototherapy (cont’d) 2. Effective irradiance delivery: uncover the baby to maximize skin exposure providing eye protection and eye care carefully monitoring thermoregulation (T°) maintaining adequate hydration document intake and output 3. Support and encourage parent-infant interaction. 51 Efficiency of Phototherapy 52 Intravenous immune globulin - It is used for numerous immunologically mediated conditions, e.g. Rh, ABO, or other blood group incompatibilities that cause significant neonatal jaundice - Studies showed that newborns received IVIG significantly reduce the need for exchange transfusions - Treatment: 500mg/kg given for a 2 hour period once diagnosed with Rh/ABO incompatibility 53 References Davidson, M.R., London, M.L., & Ladewig, P.A.W.

First period of reactivity (6 – 8 hrs after birth) – 30 minutes after birth – Awake, active, appear hungry, strong sucking reflex 2. Period of inactivity to sleep phase – Sleep phase: few minutes to 2-4 hours – Difficult to be awaken & show no interest in sucking 3. Second period of reactivity – Awake and alert – Last for 4 to 6 hours 69 Behavioral states of the newborn – reflects the infant’s ability to respond to the environment Sleep states Awake states • • Deep sleep – Sleep without movement, hard to be awaken • • Light sleep – Eyes closed with some eye movement seen under lids, active body movement; sucking might be present • Quiet alert – Alert with eyes open; attention to close objects; little body movement Active alert – Inactivity with mild agitated vocalizations.

Even in hot climates, provides sufficient water for the exclusively breastfed infant to remain adequately hydrated. Composition of Breastmilk - Lipids • About 50% of the calories come from lipids. • The primary fats identified are phospholipids and triacylglycerols. • > 167 fatty acids have been identified, many of which are long chain, polyunsaturated fatty acids. • Contains omega-3 fatty acids, including docosahexaenoic acid (DHA), important for brain and retinal development and function. • DHA: – tissue membranes require DHA – Human can convert linolenic acid to DHA but inefficiently – DHA well absorbed from breast milk, poorly absorbed from artificial milk Composition of Breastmilk - Lipids • Cholesterol, important to the development of membranes, is also present in significant quantities. • While the content of milk fat in mature human milk usually ranges from 3.5% to 3.8%, it is important to recognize that these figures represent an average fat content. In reality, the fat content is variable and influenced by a number of factors. Differences in fats of different milks HUMAN Lipase Essential fatty acids COW’S, FORMULA EFA may be added to formula What differences do you notice here? fat more -7 more energy HINDMILK FOREMILK Fat Protein Lactose Colostrum Mature Milk Foremilk Hindmilk Composition of Breastmilk - Protein • The total protein content of breastmilk, 0.9%, is the lowest among mammals. • Low protein content is well matched with the developing renal function of the neonate. • The low renal solute load places less excretory burden on the immature system • Two major components: whey and casein. • Milk curd (forms from the casein when the milk pH (normally ranging from 6.7 to 7.4) drops below 5.0) is an insoluble calcium caseinate-calcium phosphate complex. Composition of Breastmilk - Protein • Whey : water, electrolytes and important proteins: disease resistance including alpha-lactalbumin, lactoferrin, lysozyme and the immunoglobulins. • Whey : casein 80 : 20 softer gastric curd, reduced gastric emptying, facilitate digestion – Colostrum 90:10 – Mature milk 60:40 • Human milk protein is predominantly whey. – allowing for easy digestion and absorption as well as rapid transit through the intestinal tract of the human infant. – This results in the normal pattern of frequent feeding and stooling characteristic of breastfed infants. • Formula contains no proteins which protect against infection. WHO/CDR/93.6 Difference in the quality of the proteins in different milks COW’S HUMAN Anti-infective proteins Whey 80% Casein 35% Casein Easy to digest Difficult to digest 1/3 Protein • !! there are a number of nitrogen containing compounds in human milk with bioactive roles, important to the newborn and young infant. These include: – epidermal growth factor - For development and function of the intestinal mucosa – taurine - bile acid conjugation and neurotransmission – nucleotides - metabolic and immune functions – carnitine - needed in the lipolysis of long-chain fatty acids Composition of Breastmilk - CHO • Lactose, a disaccharide: galactose and glucose. • Major CHO & is essential as a source of glucose. • Also the source of galactose needed to produce galactolipids for infant brain development. • Other CHO include monosaccharides, oligosaccharides and glycoproteins. • The oligosaccharides and glycoproteins, known collectively as the “bifidus factor”, are important in stimulating the growth, and colonization of the newborn gut with Lactobacillus bifidus, a non-pathogenic bacteria which protects against invasive enteropathogens. • Oligosaccharides also prevent the adherence of bacteria to the mucosal surface and are considered a prebiotic. Composition of Breastmilk - CHO • Lactose. – – Calcium and iron absorption intestinal colonization with lactobacillus bifidus and gut flora, – promote acidity GI tract inhibit growth if pathogenic bacteria – formula-fed baby has higher pH level If – damage of intestinal brush border loss of lactase temporary lactose intolerance Composition of Breastmilk - Minerals • All minerals needed for newborn and infant growth well absorbed from human milk. • The lower quantities of minerals in human milk result in a substantially lower solute load to the infant’s immature renal system. Iron • Fe in human milk is not large (100 μg/liter), but the absorption is superior. (highly biological available 50% 70%) • Lactoferrin – contributes to iron bioavailability in human milk. – It is a protein found in whey, it binds Fe and makes it available for digestion and absorption by the infant. – This binding of iron also inhibits bacterial growth (iron unavailable to iron dependent organisms). – Too much iron in formula which are not well absorbed and favors the development of pathogenic gut bacteria by saturating lactoferrin • Normal full-term infants can be “exclusively breastfed” (no other foods or fluids) for six months without becoming iron deficient. • Absorption is enhanced by high lactose and Vit. C conc in human milk • Fe reduce zinc and copper absorption Breastmilk100mcg/L Formula milk 12mg/L Iron in milk Formula milk HUMAN 50% % absorbed 4% Zinc • Essential mineral for humans and is important to enzyme activity. • Like iron, it is well absorbed from human milk • Both iron and zinc are important to normal brain development and function. Composition of Breastmilk - Enzymes • Over 30 bioactive enzymes identified. • Some enzymes function in the synthesis of milk, some compensate for digestive enzymes needed but not yet produced in adequate quantity by the newborn, • some help transport minerals, and others are antiinfective. E.g, lipase in breast milk works synergistically with lingual lipase and gastric lipase to form an efficient system for complete digestion of human milk fat. • This is particularly important during the months after birth when pancreatic enzyme and bile salt levels are low. Composition of Breastmilk – Other Important Components • Human milk contains numerous peptide and nonpeptide bioactive hormones: – – – – – – – thyroxine, prolactin, erythropoetin, epidermal growth factor (EGF) insulin, leptin and gastrin. Prostaglandins, also present, influence gastrointestinal motility. Composition of Breastmilk – Cellular Components - Human milk is a living tissue. - contains about 4000 cells per cubic mm including neutrophils, macrophages & lymphocytes. - Neutrophils help prevent infection of the breast tissue while macrophages and lymphocytes are actively involved in providing immuno- protection for the newborn and young infant. - Macrophages secrete lysozyme, kill bacteria, and are active in phagocytosis.

This inequality persists until later in life. Growing evidence also suggests that breastfeeding might protect against overweight and diabetes later in life. Breastfeeding in the 21st century: epidemiology, mechanisms, and lifelong effect Breastfeeding benefits mothers. It can: • Prevent breast cancer, • Improve birth spacing, • Might reduce a woman’s risk of diabetes and ovarian cancer High-income countries have shorter breastfeeding duration than do low-income and middle-income countries. However, even in low-income and middle-income countries, only 37% of infants younger than 6 months are exclusively breastfed. Breastfeeding in the 21st century: epidemiology, mechanisms, and lifelong effect • The scaling up of breastfeeding can prevent an estimated 823,000 child deaths and 20,000 breast cancer deaths every year. • Findings from studies done with modern biological techniques suggest novel mechanisms that characterise breastmilk as a personalised medicine for infants. • Breastfeeding promotion is important in both rich and poor countries alike, and might contribute to achievement of the forthcoming Sustainable Development Goals. States of Lactogensis * Stages of lactation (criteria devised by Peter Hartmann) • Mammogenesis – “priming” - growth and development • Lactogenesis – onset of milk production • Galactopoiesis – maintenance of milk production • Involution – decline and cessation of lactation - of ducts and alveoli in the first 12 weeks of pregnancy the breast is prepared for lactation by 16 weeks; - Lactogenesis I - early secretory changes - colostrum - Lactogenesis II – production of copious mature milk - Lactogenesis III - or simple “lactation” - Return of mammary gland to non-lactating state Protection against infection (1) Mother infected (4) Antibodies to mother's infection secreted in milk to protect baby (2) White cells in mother’s body make antibodies to protect mother (3) Some white cells go to breast and make antibodies there sIgA (secretory IgA) • Most infections via the mucosal membranes (100 times large area than skin). 90% of micro-organizms infecting humans cross the mucosa. • Man’s mucosal immune system consist almost exclusively of specially structured antibodies to stop this type of infection. • sIgA : – – – – – main antibodies on mucosal membranes and in human milk. Not found in blood. Resist to proteolytic enzymes. sIgA :80% of all antibodies. prevent the entry of microbes into tissue. Migrates thro the epithelial cell onto the cell surface. sIgA (secretory IgA) • Prevent bacterial and viruses attaching the epithelial cells and entering the tissue. • Anti-inflammatory reaction: prevents activation of the tissue-damaging, energy consuming, proinflammatory defense of IgG, complement action and phagocytes. reserve energy for growth and development. PSYCHOLOGICAL BENEFITS OF BREASTFEEDING - Emotional bonding Close, loving relationship between mother and baby Mother more emotionally satisfied Baby cries less Mother behaves more affectionately Less likely to abandon or abuse baby BREAST-MILK IN THE SECOND YEAR Energy required by age and the amount from breast milk Energy 1200 Kcal/ day) 1000 800 600 400 200 0 0-2 m 3-5 m Energy gap Energy from breastmilk 6-8 m Age ( months) 9-11 m 12-23 m RECOMMENDATIONS Start breastfeeding within 1 hour of birth Breastfeed exclusively to 6 months of age Give complementary foods to all children from 6 months of age Continue breastfeeding up to 2 years of age or beyond Some formula? • Formula changes the gut flora in breastfed babies by breaking down the mucosal barrier that colostrum provides them. This violation allows pathogens and allergens entry into the baby’s system. (Ogawa 1992) • Supplemental bottle of artificial infant milk can sensitize a newborn to cow’s milk protein (Kalliomaki and Isolauri 2003). DANGERS OF ARTIFICIAL FEEDING Interferes with bonding More diarrhoea and respiratory infections More allergy and milk intolerance Persistent diarrhoea Increased risk of some chronic diseases Malnutrition Vit. A deficiency More likely to die May become pregnant sooner Overweight Lower scores on intelligence tests Increased risk of anaemia, ovarian and breast cancer Colostrum: all baby needs In the first few days colostrum, a low volume and high density food is produced for newborns. Babies should be exclusively breastfed and most mothers have milk come-in on 3rd day. 1st day 2nd day Milk comes in COLOSTRUM Property Antibody rich Many White cells Purgative laxative Growth factors Vitamin A rich Importance – protects against infection and allergy – protect against infection – clears meconium helps to prevent jaundice – help intestine to mature prevent allergy, intolerance – reduces severity of infection Prevent eye disease How breastfeeding works? Parts of the Breast Prolactin Secreted after feed to produce next feed Sensory impulses from nipple Prolactin in blood Baby suckling * More prolactin secreted at night *Suppresses ovulation Prolactin • After birth, ,two hormones - Prolactin and Oxytocin become important to help production and flow of milk. • Under the influence of prolactin, the breasts start to make larger quantities of milk. • It usually takes 30-40 hours after birth before a large volume of milk is produced (milk comes-in). Prolactin • Produced from the anterior pituitary gland. • Hormone that makes the alveoli produce milk. • Works after a baby has taken a feed to make the milk for the next feed. • Can also make the mother feel sleepy and relaxed. • Is high in the first 2 hours after birth, also high at night. • Breastfeeding at night allows for more prolactin secretion. Oxytocin Reflex (let-down reflex) Works before or during feed to make milk flow Causes smooth muscles to contract squeezing milk out Sensory impulses from nipple Baby suckling makes uterus contact Oxytocin • Controlled by the posterior pituitary gland. • Causes the muscle cells around the alveoli to contract and makes milk flow down the ducts. • Essential to enable the baby to get the milk. This process is called the “oxytocin reflex”, “milk ejection reflex”, or “letdown”. • It may happen several times during a feed. Oxytocin • Soon after a baby is born, the mother may experience certain signs of the oxytocin reflex. These include: – painful uterine contractions, sometimes with a rush of blood; – a sudden thirst; – milk spraying from her breast, or leaking from the breast which is not being suckled; – feeling a squeezing sensation in her breast. • However, mothers do not always feel a physical sensation. • When the milk ejects, the rhythm of the baby's suckling: rapid slow deep Oxytocin adherence Seeing, hearing, touching and thinking lovingly about the baby, helps the oxytocin reflex. The mother can assist the oxytocin to work by: - Feeling pleased about her baby and confident that her milk is best. - Relaxing and getting comfortable - Gently stimulating the nipple. - Keeping her baby near so she can see, smell, touch and respond to her baby. Oxytocin Reflex Thinks lovingly of baby Sound of baby Sight of Baby CONFIDENCE Helps reflex Worry Stress Pain Doubt Hinder reflex WHO/CDR/93.6 3/5 Inhibitor in Breastmilk Feedback Inhibitor of Lactation (FIL) If breast remains full of milk, secretion stops Feedback Inhibitor of Lactation = FIL • If milk not removed, production decreases • It is suppressed by a chemical inhibitor, FIL • FIL is an autocrine, or local, regulator of breastmilk synthesis • FIL is a peptide (small protein) made in the breast itself • If milk not removed, FIL collects in alveoli • As the concentration of FIL increases it blocks milk secretion in the mammary cell • If milk removed by suckling, concentration of FIL falls and milk secretion continues Feedback Inhibitor of Lactation • To prevent the FIL from collecting and reducing milk production: – make sure that the baby is well attached; – encourage frequent breastfeeds; – allow baby to feed for as long as she or he wants at each breast; – let the baby finish the first breast before offering the second breast; – if baby does not suckle, express the milk so that milk production continues. Milk transfer from breast to baby • The baby’s suckling controls the prolactin production, the oxytocin reflex and the removal of the inhibitor within the breast. • For a mother to produce the milk that her baby needs, her baby must suckle often and suckle in the right way. ROOTING REFLEX When something touches lips, baby opens mouth puts tongues down and forward Skill Mother learns to position baby Baby Learns to take breast SUCKING REFLEX When something touches palate, baby sucks SWALLOWING REFLEX When his mouth fills with milk, baby swallows Early skin-to-skin contact A very precious and significant moment •Uterine contraction •Decrease crying of baby •The beginning of lactation programmed to find the breast – More effective suckling – Stabilized sugar level – Regulate Tº •Bacteriological point of view colonized with the familiar and friendly germs & share the same IgG with mothers •Thermoregulation How long should skin-to-skin contact last? • At least one hour or until after the first feed. • As long as mother wishes.

Baby must be alert and shows cues of feeding • Baby can smell the milk • Help digestion and learning • Can be used for preterm baby • Involvement of the tongue • Sit upright • Rest the cup on the lower lip, don’t press too heavy • No pouring of milk How to assure successful breastfeeding? THE WHO 10 STEPS TO SUCESSFUL BREASTFEEDING 1. Have a written breastfeeding policy that is routinely communicated to all health care staff. 2. Train all health care staff in skills necessary to implement this policy. 3. Inform all pregnant women about the benefits and management of breastfeeding. 4. Help mothers initiate breastfeeding within a halfhour of birth. 5. Show mothers how to breastfeed, and how to maintain lactation even if they are separated form their infants. 6. Give newborn infants no food or drink other than breastmilk, unless medically indicated. 7. Practise rooming-in – allow mothers and infants to remain together – 24 hours a day. 8. Encourage breastfeeding on demand. 9. Give no artificial teats or pacifiers (also called dummies of soothers) to breastfeeding infants. 10.Foster the establishment of breastfeeding support groups and refer mothers to them on discharge from the hospital or clinic. Hospital Policies: % of mothers, breastfed < 6 weeks Increased number of “Baby-Friendly” Hospital practices in place decreases risk of breastfeeding cessation 30.0% 26.9% 21.5% 15.5% Steps measured: Early bf initiation Exclusive breastfeeding Rooming-in On-demand feedings No pacifiers Information provided 13.7% 6.2% 0 1 2 3 4 5 3.2% 6 Number of Baby-Friendly steps mothers reported experiencing DiGirolamo, Pediatrics, 2008 Duration of any breastfeeding by number of baby‐friendly steps experienced Tarrant, M.

Protect Breastfeeding • International Code of Marketing of Breast-Milk Substitutes – Formula milk – Bottle & Teat – Cereal and baby food Compliance with the WHO international code of marketing of breast milk substitutes means; • • • • • • • NO advertising. NO donations. Of Breastmilk NO free samples. Substitutes NO promotion. NO gifts. NO pictures idealising formula feeding. NO use of equipment sponsored or produced by formula companies. The International Code on the Marketing of Breastmilk Substitutes is widely violated in Hong Kong. Marketing of Formula Milk in Hong Kong 2013 (From DH, Hong Kong) Breastfeeding/Provision of Human Breast Milk=Primary Prevention! Think! • What practice will damage breastfeeding? – – – – – Government Community Commercial Family …… Breastfeeding Myths • Breastmilk is not enough for babies • Mother doesn’t have enough milk because her breasts are small, she is old, she …. • Mother should not breastfeed when: she is ill, she takes medication, she has breast problems, she is C/S, …… • Babies should not be breastfed when he has NNJ, he is X months old, he is sick, he has teeth, ….. Good Professional, consistent advice helps mothers to breastfeed for longer How to sustain breastfeeding • • • • Promotion Initiate breastfeeding Establish breastfeeding Sustain breastfeeding Mother may stop breastfeeding because • Of the attitudes and beliefs in their community • They have to resume work outside home • Because health care practices are not supportive Support Breastfeeding & Work Two half hour breastfeeding break for staff Breastfeeding Friendly Premies Neonatal Jaundice Neonatal Jaundice (Hyperbilirubinaemia) Definition:Increase serum bilirubin visible yellowing of skin, sclera … Bilirubin • In the fetus –the placenta eliminate most of the lipid-soluble bilirubin. • In the newborn –bilirubin must be conjugated in the liver to a water-soluble form, before it can be excreted in the bile. • An endogenous ‘anti-oxidant’ produced in the body. 3 Metabolic Pathway of Bilirubin Red Blood Cell Breakdown of RBC Haemoglobin Haem Iron Bilirubin (unconjugated, fat-soluble) Globin Unconjugated Bilirubin (Blood) Activity of enzymes Physiological jaundice Conjugation in Liver Portal circulation Prematurity Infection Conjugated Bilirubin (Direct Bilirubin) Hypothyroidism (water soluble) Bile Bile Duct Enterohepatic Circulation Stool / Urine Reabsorption & rehydrolysed •Biliary atresia •Choledocal cyst Dark color urine • In normal metabolism, lipophilic bilirubin, which results predominantly from the catabolism of red cells, circulates in blood mainly as a noncovalent conjugate with serum albumin. • After uptake by the liver, it is converted into two isomeric monoglucuronides and a diglucuronide (direct bilirubin) by the enzyme uridine diphosphate glucuronosyltransferase. Premature Infants At a higher risk for problems: • Have a lower plasma albumin level • Have a lower albumin binding capacity • Blood-brain barrier –more porous to the bilirubin (e.g. anoxia) Bilirubin levels in pre-term infants peak later at 5 to 7 days of life. 11 Breastfeeding Preterm or Late Preterm Infants • Jaundice in late preterm infants results from: – Increased bilirubin due to increased bilirubin production – Decreased bilirubin elimination – Insufficient breast milk intake even when mom’s milk established – Inability to ingest larger volumes of breast milk • Hyperbilirubinemia in late preterm infants: – Increased incidence – Increased severity – Longer course – Increased risk of deleterious consequences 12 Breastfeeding & Jaundice • • • • • • • • Not enough Breast milk Jaundice/ Breastfeeding Jaundice Hospital routines which lead to insufficient breastfeeding Baby poorly latched-on Mother’s milk take longer to ‘come in’(not common) Breast Milk Jaundice ?Etiology Onset after day7 Thriving baby Peaks at 10-21 days, lasts for 2-3 months An extension of physiological jaundice 13 Management of NNJ • Assessment • Observation • Treatment – Ensure adequate intake – Phototherapy – Exchange transfusion Findings • History taking • Onset of NNJ, any onset within 1st 24 hrs should be assumed as serious. • Examine under good daylight: face, chest, hands and feet. • Take blood for serum bilirubin, haemoglobin, (if necessary baby’s blood group and perform Coomb’s test.) Assessment for NNJ • • • • Yellowing of skin Pallor Any source of haemolysis Hydration of baby Phototherapy • PT is the use of visible light for the treatment of hyperbilirubinemia in the newborn. • This relatively common therapy lowers the serum bilirubin level by transforming bilirubin into watersoluble isomers that can be eliminated without conjugation in the liver. • The dose of phototherapy largely determines how quickly it works; the dose, in turn, is determined by the wavelength of the light, the intensity of the light (irradiance), the distance between the light and the infant, and the body surface area exposed to the light. Phototherapy • Effective irradiance delivery: – – – – – – maximizing skin exposure, providing eye protection and eye care, carefully monitoring thermoregulation, maintaining adequate hydration, promoting elimination, and supporting parent-infant interaction. NNJ and BF • Breastfeeding Jaundice – Developed in early days – ↓ BF performance – Not enough breastmilk intake – Overlap with physiological jaundice – NNJ resolved if BF improves • Breastmilk Jaundice – – – – Develop around D10-14 Thrival babies BF well Arise from the pathway of conjugation – Subside gradually, can last for few months How to help a baby with NNJ • Early and effective breastfeeding • Frequent feeding • Assess and ensure mother’s feeding technique and baby’s effectiveness in getting mother’s milk • Ensure FOLLOW UP in the first week of life • Increase baby’s intake – More feeding – Extra express breastmilk to baby is baby is sleepy SN3180: Childbearing Family Nursing Puerperium – Psychological & physiological changes Kitty Wong 2018 –1 Learning outcome By the end of the study, students should be able to: 1. 2. 3. 4. 5. 6.

From Ms Christine Lam, (All needed) Nurse Consultant of Lactation, QEH Breast engorgement: For NON-lactating mothers – management occurs Day 3 after baby birth put on brassiere for support apply ice/ cool packs on upper chest if engorged avoidance of nipple stimulation oral analgesics p.r.n. to relieve pain 45 Breastfeeding problem Sore nipples in lactating mothers Possible causes: 1. improper positioning and latch-on 2. not breaking suction before removing baby from breast 3. breast engorgement, 4. prolong exposure to moist 5. Improper use of breast pads 46 breaking suction before removing baby from breast 47 Breastfeeding problem Management of Sore nipples in lactating mothers 1. 2. 3. 4. 5. 6. 7. 8. 9. Position the infant appropriately Change baby’s position during nursing Attachment : Area of nipple directly in line with baby’s nose and chin Offer the breast which is less sore first Express some milk before feeding to enable the infant latch onto the nipple more easily Massage the breasts during breastfeeding to enhance milk flow Use breaking suction before removing baby from breast Apply breast milk to nipples after feeding to help healing Expose the nipples to air dry in between feedings 48 Breastfeeding: (guest speaker) Assessing baby to have enough milk • Can hear baby swallowing frequently during feedings • Breast is getting softer during feeding • Milk can be seen in baby’s mouth or dripping • Feeding 10 to 12 times per day initially • For exclusively BF baby, 6 or more soaked nappies a day, and a weight gain of 0.5 kg per month after the initial physiological weight loss in the first few days (HKDH, 2006; Wong, 2012) 49 Breastfeeding problem Mastitis in lactating mothers ' inflammation of Mammaryglands 1. occurs 2-3rd wks postpartum, 5% of BF mothers affected 2. S/S: high fever, chills, localized redness & pain, hard & tender on ONE breast 50 Breastfeeding problem Mastitis in lactating mothers Cause: 3. by Staphylococcus aureus -> on hands of mothers/ health care staff -> the mouth of baby -> crackle -> stasis of breast milk Treatment : 4. i. ii. iii. iv. v. vi. penicillin, erythromycin, analgesics surgical drainage of the abscess if abscess occurs Moist heat / cold packs Breast support Bed rest Increase fluid intake 52 Postnatal Follow Up (~ 6 weeks) - to evaluate maternal condition on: • general health status, vital signs, BP, urinalysis, skin color, edema • wound condition, presence of vaginal discharge • involution of the uterus, duration of lochia • return of menstruation • baby feeding & lactation • emotional states, morale & parenting ability • Postnatal exercises for muscle strength & overall wellness • resumption of sexual activity • use of contraceptive devices 53 Evaluation: the client can 1. have normal uterine involution process & show no signs of physical complications 2. shows confident & demonstrates ability in self care & infant care/ feeding 3. verbalize how to take care on self & infant at home 4. verbalize the s/s of complications or difficult issues in daily care 5. use community resources for support if required 6. obtain legal documents for the child (birth certificate) 7. show stable emotional state 8. adjust & integrate to the arrival of the newborn 54 Documentation in ward i. ii. A daily observation chart is used to note all the observations on the maternal condition Other observations on mother’s emotional state are also recorded 55 Postnatal exercise Advantages/significance: • promote involution of uterus • promote healing • restore muscle tone • improve circulation • prevent complications (e.g. prolapse of cervix) • quicker return to fitness & body figure • improve appetite 56 Supplementary: Postnatal exercise Advice: For women with NSD – begin as soon as possible For women after CS – usually from Day 4, but consult doctor for exercise regimen i. suggest: - a new exercise can be added daily - begin with easy exercise - 10 minutes twice daily ii. no vigorous exercise until the lochia is clear iii. continue the exercise until the end of puerperium to have maximum benefit iv. avoid fatigue 57 Suggested exercises 58 Reading materials/ reference Davidson, M.R., London, M.L., & Ladewig, P.W.(2014).

To prevent sexual transmitted infections To reduce the risk of having cervical cancer (HPV) To prevent unwanted pregnancy 1. TO PREVENT STI AND INFECTIONS THROUGH SEXUAL TRANSMISSION Agents may cause sexually transmitted infection Bacterial : – Syphillis (Treponema pallidum) – Gonorrhoea (Neisseria gonorrohoeae) – Chlamydia (Chlamydia trachomatis) – Chanchroid (Haemophilus Ducreyi) Protozoan: - Trichomoniasis (Trichomonas vaginalis) Agents may cause sexually transmitted infection (cont’d) Viral: Viral hepatitis B Herpes simplex (Type II) Human Papillomavirus (HPV) Human Immunodeficiency Virus (HIV) Fungal: Candidiasis (yeast infection) • Parasite: – Crab louse (pubic lice) – Scabies 2. TO REDUCE THE RISK OF HAVING CERVICAL CANCER Unsafe sex and cervical cancer Higher risk of developing cervical epithelial abnormality in those: Multiple sexual partners Higher chance to contact with HPV Unprotective sex Onset of sexual activity less than aged 18 ↑denudation of stratified epithelium ↑exposure of the basal layer to HPV Prolonged use of oral contraceptives Direct contact of penis with HPV virus (Louie et al., 2009), (Wong et al., 2011) 3. TO PREVENT UNWANTED PREGNANCY Factors leading to unwanted pregnancy • • • • Unplanned sexual activity Unprotected sex Inaccurate use of contraceptive methods Defective contraceptive articles, etc Principles of contraception 1. Avoid combination or encounter of sperm and egg 2. Avoid zygote implantation 3. Control ovulation Office of National Statistics (ONS) in UK – 10 most popular types of contraception: 1. 2. 3. 4. 5. Contraceptive pills Male condom Vasectomy Female sterilization Intrauterine contraceptive device (the coil) 6. Withdrawal method At ¥ I 7. 8. 8. 10. 11. Rhythm method Contraceptive injection Skin patch Cap/ diaphragm Implant 12. Female condom 13. Vaginal ring 28 Oral contraceptives - contain estrogen and progesterone Use: Suppress ovulation and cause thickening of the cervical mucus to block sperm penetration Reliability: 92-99% Directions: For 28 days packet Take one tablet daily for 28 days in the order specified in the packet. Start a new packet the day after taking the 28th tablet. For 21 days packet One tablet daily for 21 days. After 21 days, stop for 7 days. Menstruation period may come after stopped for 1~2 days. Follow the instruction to restart another packet of pills, e.g. start on the 5th or 7th day. Oral contraceptives Advantages: i. Continuous protection for preventing pregnancy ii. regular and shorter menstrual periods iii. Able to resume pregnancy iv. Protects against ovarian and endometrial cancer Disadvantages: a. May decrease vaginal lubrication or diminish libido b. Must remember to take daily c. Possible side effects: nausea, breast tenderness, mild headaches, weight gain or loss. d. Higher health risks for women over 35 who smoke (eg. Stroke) e. ADD barrier methods during the period in taking 1st packet of contraceptive pills f. No protection against STI Male condom It forms a barrier to prevent sperms go to vagina Reliability : Contraception: 98% Prevent 80% to 95% of HIV transmission Male condom (cont’d) Advantages: Protection against STI inexpensive Easy to access Disadvantages: May fall off, leak or break if not used properly Embarrassed to purchase or to apply condoms Less protection against infections that are transferred by skin contact (e.g. HPV) Very few side effects, unless one is allergic to latex or to the lubricant or spermicide IUCD Intrauterine contraceptive device - last for 5 - 12 years vs. types of IUCD [hormonal, copper] - It will be inserted with surgical procedure done by doctor at clinic - Insert after a thorough physical and vaginal assessment Contraindications for IUCD 1. Have pelvic infections or abortions in the past 3 months 2. Have / may have STI 3. Have/ may get pregnant 4. Unexplained bleeding from vagina 5. Pelvic tuberculosis 6. Uterine perforation during insertion Periodic abstinence The various methods used for estimating the fertile period Correct use: Avoid sexual intercourse during fertile period Estimated by the calendar method, charting daily basal body temperature, or detecting changes in cervical mucus Reliability: 97.9% effective only when an electronic hormonal fertility monitor is correctly used & correct cervical mucus observations (Fehring, Schneider & Raviele, 2007). (The Family Planning Association of Hong Kong, 2012) Periodic abstinence Advantages: Costless No side-effects only method acceptable to some couples with religious beliefs. Disadvantages: Not for women with irregular cycles Does not protect STI difficult to abstain from sexual intercourse during fertile period Need careful instruction Withdrawal method To pull one’s penis out of the vagina before ejaculation also known as coitus interrupts. (Pull Out Method - Withdrawal Method, 2012) Reliability: 18% of couples will become pregnant in a year (Kost, Singh & Vaughan, 2008). Only reliable when men can pull out accurately before ejaculation Pregnancy can still happen if pre-ejaculate, or pre-cum occurs. Withdrawal method (cont’d) Advantages: Costless No side effects Efficacy increases with higher educational background (Güngör, Başer & Göktolga, 2006). Disadvantages and potential restrains: Requires great self-control, experience, and trust Not for men who ejaculate prematurely Not for teens and sexually inexperienced men Pregnancy is possible Does not protect against STI Depot medroxyprogesterone acetate (Depo-Provera/DMPA) Reliability: 99.7% Direction: • Injection for every 3months • Contains progestin • Cause uterine lining to be dry and brittle • Require a visit to healthcare provider for every year Advantages: • Convenient for those who has low risk of getting STI • Very low chance of getting pregnant (Sterilization with 0.5%) Disadvantages: • Does not protect client from STI • Withdrawal bleeding • Weight gain • Depression • Increased risk of osteoporosis (Cromer, 1999) (Cropsey, Matthews, Campbel, Ivey & Adawadkar, 2010) Emergency contraceptive pills(ECPs) Levonorgestrel-only or combined estrogen-progestogen Actions: öPrevent an unintended pregnancy öInhibit ovulation öCause thickening of the cervical mucus Reliability: 60-90% effective, but failure rate increases progressively each additional day between unprotected intercourse and taking the pills Emergency contraceptive pills(ECPs) Use: • Should be taken as early as possible after unprotected intercourse, within 72 hours. • Effectiveness is reduced with increased lapping time • Cannot act as an abortifacient Emergency contraceptive pills Advantages To prevent pregnancy after unprotected vaginal intercourse Disadvantages Many side effects : breast tenderness, fatigue, headache, nausea, abdominal pain and dizziness Not effective once implantation has begun Not suitable for women with blood clotting disorders, breast cancer, diabetes, hypertension or with past history of CVDs Next menses may be early or late Not suitable for regular use (once a year) Does not protect against STI Contraceptive method Condom Pills Periodic abstinence Withdrawal Picture Reliability 98% 92-99+% 97.9% 82% function Use a latex layer to separate sperms and ovum Use pills to inhibit ovulation/integrate Avoid sexual activity when ovulation period pull penis out before ejaculation Advantages - Cheap -Few side effects -Safe -Can against STD -Reliable -Almost 100% reliable - x pregnancy after unprotected sexual activity - Costless -No side effects -Safe -Convenient - Costless -No side effects -Safe -Convenient Disadvantages -Allergy / -Affect enjoyment Complications -break or slip off -Drug allergy -Need to consult doctor -with more S/E -induce health risks -not protect from STI -Need the normal work of hormone -Not reliable with irregular cycles -not protect from STI - difficult to control -Affect enjoyment -Not reliable -not protect from STI Note - May reduce menstrual discomfort May be the only method of birth control to some religion The fluid secretes before ejaculation also have sperms It has different texture/ taste to increase exited Conclusion Different people have different characteristics and preferences ,it leads to various contraceptive methods. Generally, people are based on the following criteria to choose their own suitable contraceptive method: • • • • • • • Reliability Existing Material Safety/ Side effect The enjoyment during the process Age/ Pregnancy before or not Temporary/Permanent Religion SN3180 Pregnancy related issues: Infertility Kitty Wong Nov 2018 1 Learning outcomes: students should be able to I. List and describe the types and its possible causes of infertility II. Briefly describe the management of infertility related to: a. investigation b. management c. prevention III. Briefly describe the nursing management in supporting the couple with infertility issue 2 Review: reproductive systems of man and woman 3 Fertility • Women – From menarche to menopause – At birth, each ovary contains roughly 500,000 ovarian follicles [also called Graafian follicles] (these follicles are the immature form of ovum) – For a female, < 500 ova produced from puberty to her reproductive years • Men – Sperms: from onset of puberty → his life span – Capacity to reproduce sexual excitement, penile erection & ejaculation 4 Essential Components of Fertility in Women 1. Normal ovaries and ova 2. Patent fallopian tubes, normal fimbria(e) with peristaltic movements 3. Endometrium functions normal for implantation 4. Adequate reproductive hormones 5. Favorable cervical mucus for survival of spermatozoa 5 Cervical secretions favours sperms passing through - 7 Essential Components of Fertility in Men 1) Testes must produce spermatozoa of normal quality, quantity, and motility 2) Unobstructed male genital tract 8 Essential Components of Fertility in men: 1. Male genital tract secretions: normal 2. Ejaculated spermatozoa must be deposited in the female vagina into cervix 3. Semen and sperms 9 Semen and sperms During ejaculation, it receives fluid from seminal vesicles and the prostate glands ⇝ ~ 2 – 5 ml per ejaculation ⇝ spermatozoa and fructose-rich nutrients ⇝ sperm counts: 20 million spermatozoa / ml or more ⇝ sperm movement: 60 - 80% of the sperm show normal forward movement after 1 hour ⇝ sperm morphology: > 30% of the sperm have normal shape ⇝ pH : 7.1 – 8.0 10 Semen and sperms ⇝ Effective transportation of sperm requires adequate nutrients, an adequate pH (about 7.5), a specific concentration of sperm to fluid, and an optimal osmolarity ⇝ appearance: thick, whitish ⇝ odour: musty ⇝ Once ejaculated, sperm can live only 2 or 3 days in the female genital tract (sperm may be stored in the male genital system up to 42 days, depending primarily on the frequency of ejaculations) 11 Infertility 13 Define Infertility is defined by the failure to achieve a successful pregnancy after 12 months or more of regular unprotected intercourse. Types: 1. Primary - biological inability of a person to contribute to conception 2. Secondary – couples who have been unable to conceive after one or more successful pregnancies 3. Subfertility – a couple having difficulty conceiving because both partners have reduced fertility 14 Define Sterility is a term applied when there is an absolute factor preventing reproduction Types: - Postpartum Sterilization (PPS) - Tubal ligation - vasectomy 15 Causes of infertility Cause % Tubal factor 11 Endometriosis 6 Ovulatory dysfunction 6 Diminished ovarian reserve (DOR) 7.9 DOR refers to the condition of having a low number of normal oocytes or having poor quality oocytes.

Probably responsible at brain for excitement & feeling of attachment & sex A study with 49 men and women into a brain scanner to understand the ecstasy: # Pfa € Sex drive: testosterone 睾丸素 Igt € Romantic love: increased dopamine 多巴胺 & norepinephrine serotonin 血清素 (optimal) ) € Deep attachment: oxytocin & vasopressin Fisher, H. (2004).Why we love: The nature & chemistry of romantic love. NY: Henry Holt & Co. 4 Pleasure & desire Different in cultures and different in persons! Sexual desire can be directed at a specific gender, body part, personality trait, … Sexual pleasure can range from mental fantasies, to masturbation of the genitals, to a simple touch of a partner’s fingertips – consent (willingness to engage in sex) Kinsey, A., Pomeroy, W. & Martin, C. (1975). Sexual behaviour in human male. Bloomington: Indiana University Press. 5 The human sexual response cycle (4-stage-model) 1. excitement phase (initial arousal) Vaginal lubrication vs. erection of penis 2. plateau phase (at full arousal) Outer 1/3 of vagina markedly engorged, clitoris retracts 3. orgasm Contractions in the outer 1/3 of the vagina, uterine contractions begin, rate, respiration, blood pressure heart 4. resolution phase (after orgasm) – Masters, W. & Johnson, V. (1966). Human sexual response. NY: Ishi Press International 6 Male sexual response cycle 6/20/2016 School of Nursing, The Hong Kong Polytechnic University 7 Female sexual response Phase 1:murmur excitement phase - last from a few minutes to several hours, include the following: • • • • • Muscle tension increases. Heart rate quickens and breathing is accelerated. Skin may become flushed (blotches of redness appear on the chest and back). Nipples become hardened or erect. Blood flow to the genitals increases, resulting in swelling of the woman's clitoris and labia minora (inner lips), and erection of the man's penis. • Vaginal lubrication begins. • The woman's breasts become fuller and the vaginal walls begin to swell. • The man's testicles swell, his scrotum tightens, and he begins secreting a lubricating liquid. 9 Phase 2: Plateau murmur - extends to the brink of orgasm as below: • The changes begun in phase 1 are intensified. • The vagina continues to swell from increased blood flow, and the vaginal walls turn a dark purple. • The woman's clitoris becomes highly sensitive (may even be painful to touch) and retracts under the clitoral hood to avoid direct stimulation from the penis. • The man's testicles are withdrawn up into the scrotum. • Breathing, heart rate, and blood pressure continue to increase. • Muscle spasms may begin in the feet, face, and hands. • Muscle tension increases. 10 Phaseummm 3: Orgasm - climax of the sexual response cycle - the shortest of the phases and generally lasts only a few seconds. Involuntary muscle contractions begin. Blood pressure, heart rate, and breathing are at their highest rates, with a rapid intake of oxygen. Muscles in the feet spasm. There is a sudden, forceful release of sexual tension. In women, the muscles of the vagina contract. The uterus also undergoes rhythmic contractions.
