Obstetrical Emergencies Silver Cross EMS CME June 2011 2nd Trimester Instructor/Author: Lonnie Polhemus RN, NREMT-P OB/GYN Emergencies • Many types of emergencies can occur with female reproductive system • Gravid and non-gravid • Following information will help you refresh assessment & treatment skills for emergency childbirth & gynecological emergencies Because we have to have objectives • • • • • Identify anatomic structures and functions of female reproductive system. Demonstrate basic understanding of pregnancy physiology and menstrual cycle, ovulation, and fetal development. Identify signs/symptoms and proper care for gynecological emergencies. Identify key aspects of evaluating pregnant patient to determine if birth is imminent. Identify purpose and use of tools in an OB kit. More objectives • • • • • • Identify steps for normal delivery of infant. Identify how and when to cut umbilical cord. Identify steps for post-delivery care of newborn/mother including placenta delivery. Identify critical treatment interventions for pregnancy complications • • • • breech (buttocks) or limb presentation shoulder dystocia prolapsed cord postpartum bleeding. Identify steps for assessing infant APGAR score. Identify steps for neonatal resuscitation Terms to become familiar with •abruptio placenta — When placenta prematurely separates from uterine wall, causing heavy internal bleeding and pain •Can occur as a result of trauma. •bloody show — Mucous and blood that comes from vagina as first stage of labor begins. •Cervix sealed by a plug of mucus during pregnancy to prevent contamination. •When cervix dilates, plug expelled as pink-tinged mucous. •crowning — Bulging out of the vaginal opening caused by the baby’s head pressing against it. And these too •dilation — To get larger or enlarge. •Degree of dilation of cervix often key indicator used by midwives and physicians to determine if birth is imminent. •EMTs/paramedics do not perform this test. •Process occurs over a period of several hours in some women, but can take much longer. •eclampsia (toxemia) — Serious condition that can develop in the third trimester. •Characterized by high blood pressure and excessive swelling in the extremities and face. •Life-threatening seizures differentiate eclampsia from preeclampsia. A few more terms •ectopic pregnancy — Condition where fertilized egg implants outside uterus, often in fallopian tubes. •Symptoms can include abdominal pain, bleeding (intraperitoneal or vaginal). •effacement — Term relating to thinning of cervix. •meconium — Dark-green fecal material found in intestines of fullterm babies. •Ordinarily meconium is passed after a baby is born. •In some cases, meconium expelled into the amniotic fluid prior to birth. •Gives fluid greenish-brown color known as meconium staining. Almost done •placenta previa — A condition where placenta sits low in uterus, blocking cervix. •Can present with painless, bright red bleeding. •postpartum — A term used to describe the period shortly after childbirth. Only three more terms •preeclampsia — Condition in pregnant women characterized by high blood pressure, abnormal weight gain, edema, headache, protein in the urine, and epigastric pain. •If untreated, preeclampsia can progress to eclampsia. •supine hypotensive syndrome — Weight of unborn fetus and uterus puts pressure on inferior vena cava. •Result is inadequate venous blood return to the heart, reduced cardiac output, and lowered blood pressure. Last one for now • Braxton-Hicks — Defined by Taber's Medical dictionary as intermittent, painless contractions that may occur every 10 to 20 minutes after the first trimester of pregnancy. • First described in 1872 by British gynecologist John Braxton Hicks. • Sometimes called pre-labor contractions or Hicks sign. • Not everyone will notice or experience these contractions, and some will have them frequently. • Some mothers notice them more in subsequent pregnancies than in first pregnancy. Female Anatomy of the reproductive organs •Cervix – opening of the uterus – First stage of birth, cervix opens & thins – Allows fetus to move into vagina – Opening process called dilation • Endometrium – inner lining of uterus – Each month built up in anticipation of implantation of fertilized egg – Fertilization does not occur, lining simply sloughs off • Referred to as menstrual period •Fallopian tubes – long slender passageways connect uterus to ovary – Female egg (ovum) passes through structure on its way to uterus for implantation to uterine wall • Ovaries – two almond-sized glands located on each side of uterus behind & below fallopian tubes – Produce estrogen & progesterone in response to follicle stimulation hormone (FSH) & luteinizing hormone (LH) secreted from pituitary gland Female Anatomy •Perineum – area between vaginal opening & anus – It sometimes is torn during birth which causes bleeding • Uterus – pear-shaped, muscular organ holds fetus during pregnancy – Contracts to push fetus through cervix & into vagina during birth • Vagina – flexible, muscular tube about three inches long – Called birth canal – Fetus moves from uterus through cervix into vagina & then out of mother’s body Fetal Anatomy •Placenta – develops early in pregnancy & performs important functions – Exchanges respiratory gases – Transports nutrients from mother to fetus – Excretes waste – Transfers heat – Active endocrine gland produces several important hormones – Attached by umbilical cord • Vein - transports oxygenated blood toward fetus • Artery – return deoxygenated blood to placenta •Amniotic sac – develops early in pregnancy – Consists of membranes surround & protect developing fetus – Fills with amniotic fluid cushions fetus & provides stable environment • Umbilical cord – attaches fetus to placenta – Contains one vein & two arteries – Vessels in umbilical cord similar to pulmonary circulation • Arteries carry deoxygenated blood • Veins carry oxygenated blood – Newborn cord is about two feet long Fetal Anatomy Assessment of the OB/GYN patient Assessment • Recognition of pregnancy – Breast tenderness – Urinary frequency – Amenorrhea – Nausea/Vomiting Assessment • Obstetric History – Gravidity and Parity • Gravidity = Number of pregnancies • Parity = Number of live births Assessment • Obstetric History – Last normal menstrual period – Estimated delivery date (-3/+7) – Previous Ob-Gyn complications – Prenatal care (by whom) – Previous Cesarean sections Assessment • Obstetric Physical Exam – Evaluation of Uterine Size • • • • 12 to 16 weeks: above symphysis pubis 20 weeks: at umbilicus For each week beyond 20 weeks: 1 cm above umbilicus At term: near xiphoid process Assessment • Obstetric Physical Exam – Presence of fetal movements • ~20th week – Presence of fetal heat tones • ~20th week • Normal: 120 to 160/minute Assessment • Presence of Pain – Abdominal pain in last trimester suggests abruption until proven otherwise – Appendicitis may present with RUQ pain Assessment • Presence of vaginal bleeding – Always dangerous in first trimester – Dangerous in late pregnancy if greater than normal period Assessment • General health – Diabetes may become unstable • Hypoglycemic episodes in early pregnancy • Hyperglycemia as pregnancy progresses – Hypertension complicated by PIH – Cardiovascular disease may worsen Assessment • Warning signs – Vaginal bleeding – Swelling of face, hands – Dimmed, blurred vision – Abdominal pain Assessment • Warning signs – Persistent vomiting – Chills, fever – Dysuria – Fluid escape from vagina Gynecology Menstrual cycle • Woman’s monthly hormonal cycle in which uterus prepares to receive egg • Then discharges a bloody fluid • Cycle repeats on average every 28 days, but can vary widely Menstrual cycle •Days 1 to 5 – Egg not fertilized, hormone levels lower, causes thickened lining of uterus to shed – Results in a woman’s period – First day of menstrual bleeding is Day 1 in menstrual cycle • Days 6 to 14 – Pituitary gland produces hormone, stimulates ovaries to develop follicles –Each follicle contains an egg – Only one egg reaches maturity & has potential to become fertilized – Hormone levels increase, lining of uterus thickens & prepares to receive mature egg •Days 10 to 18 – Hypothalamus & pituitary glands release hormone, mature follicle bursts & releases egg – Ovulation typically occurs midway through menstrual cycle on Day 14 – Egg begins its journey down fallopian tubes to uterus – Time period when a woman is most likely to become pregnant • Days 16 to 28 – After releasing egg, ruptured follicle secretes progesterone –Progesterone continues to thicken lining of uterus in preparation for fertilized egg – If egg is fertilized by sperm, it implants in lining of uterus – If egg not fertilized or implanted, lining of uterus shed again at next menstrual cycle Pelvic Inflammatory Disease • Pelvic inflammatory disease (PID) – infection of female reproductive tract – Organs most commonly involved – Uterus – Fallopian tubes – Ovaries – Occasionally, peritoneum & intestines Pelvic Inflammatory Disease •Symptoms of PID include: –Lower abdominal pain –Fever –Abnormal vaginal discharge –Painful intercourse –Irregular menstrual bleeding –Pain in right-upper quadrant •Vaginal bleeding & lower abdominal pain can indicate serious gynecological problem • Maintain high index of suspicion when encountered Pelvic Inflammatory Disease • Causes of PID – Gonorrhea & Chlamydia infections • Can progress undetected before PID symptoms appear – Other bacteria, such as staph or strep. • Acute or chronic – Allowed to progress untreated, sepsis can develop • Most common symptom of PID – moderate to severe, lower abdominal pain Vaginal Bleeding • Vaginal bleeding not result of direct trauma or normal menstrual cycle can indicate serious problem • Difficult to isolate specific cause, treat all vaginal bleeding as if there is serious underlying condition • Especially true if bleeding associated with lower abdominal pain Vaginal Bleeding • Treatment depends on patient’s needs, but may include the following: – Maintain ABCs – Control bleeding, if possible – Administer oxygen – Place in shock position – Provide fluid replacement – Large bore IV if needed Dilation and Curettage (D&C) •Dilation – opening of the cervix • Curettage – scraping the walls of uterus • Surgical procedure – usually done on outpatient basis under local anesthesia – Diagnose conditions such as cancer – Remove tissue after miscarriage – Elective abortion •Complications – Heavy bleeding – uncommon • Patients with heavy bleeding – Evaluate for signs of shock – Expedite transport to hospital Ectopic Pregnancy •Egg released from ovary, cyst often left in its place • Cyst – fluid-filled sac that is often enlarged • Can rupture & cause abdominal pain • Occasionally cysts develop independent of ovulation Sexual Assault • Rape – any genital, oral or anal penetration by a body part or object, through use of force or without victim's consent • It is a crime of violence with serious physical and psychological implications Sexual Assault •Trauma to woman’s external genitalia can be difficult to treat – Need to maintain patient’s modesty – Rich network of nerves in external genitalia makes such injuries painful •Tends to bleed profusely due to rich blood supply •Treat open genitalia wounds with sterile compresses • Use direct pressure to control bleeding if severe • Do not place dressings in the vagina Obstetrics Ovulation •Pregnancy begins with ovulation in female • Fourteen days before beginning of next menstrual period, ovary releases egg into the fallopian tube • Egg enters fallopian tube for transportation to uterus –Intercourse 24-48 hrs before ovulation – Fertilization should occur in fallopian tube Ovulation •Once fertilized, egg begins to divide • Fertilized egg continues down fallopian tube to uterus • Attaches to endometrium Trauma •Direct abdominal trauma can cause: – Premature separation of placenta from uterine wall – Premature labor – Abortion – Uterine rupture – Fetal death •Fetal death can result from: – separation of placenta from uterine wall – maternal shock – uterine rupture – fetal head injury Gestational Diabetes • Some women develop diabetes during pregnancy • Pregnant diabetics prescribed insulin if blood sugar cannot be controlled by diet alone • Cannot be managed with oral drugs • They are absorbed into placenta & can adversely affect fetus Ectopic Pregnancy •Implantation of growing fetus in location other than endometrium • Most common site is in one of the fallopian tubes • Surgical emergency because tube can rupture & cause massive bleeding 1 month gestation 6 weeks gestation Ectopic Pregnancy • Patients with ectopic pregnancy often have one-sided, lower abdominal pain • Late or missed menstrual period • Occasionally vaginal bleeding • Life-threatening emergency • Treat for shock, initiate immediate transport Vaginal Bleeding (Gravid) •Vaginal bleeding during pregnancy cause for concern. • Bleeding in early pregnancy often associated with: • spontaneous abortion •ectopic pregnancy •vaginal trauma • Vaginal bleeding in third trimester usually caused by: – abruptio placenta – placenta previa – trauma to vagina or cervix • Can be a life-threatening emergency! Vaginal Bleeding (Gravid) • Range: light spotting to massive hemorrhage • Difficult to find cause of in field • Suspect placenta previa, abruptio placenta, or vaginal trauma in third trimester bleeding Abruptio Placenta •Premature separation of placenta from wall of uterus • Separation either partial or complete –Complete separation usually results in death of fetus •Several factors may predispose patient to abruptio placenta – Preeclampsia – Maternal hypertension – Multiparity – Abdominal trauma – Short umbilical cord Placenta Previa •Attachment of placenta in lower part of uterus covering cervix • Unless sonogram done, placenta previa usually is not detected until third trimester • When fetal pressure on placenta increases or uterine contractions begin, cervix thins out resulting in bleeding from placenta Gravid Hypertension • Preeclampsia – condition characterized by high blood pressure, abnormal weight gain, edema, headache, & protein in urine • Eclampsia – characterized by high blood pressure & excessive swelling in extremities & face • Life-threatening seizures differentiate eclampsia from preeclampsia Pre-Eclampsia • Variety of signs and symptoms including: – Hypertension – Abnormal weight gain – Edema – Headache – Protein in the urine – Epigastric pain • If untreated, preeclampsia can progress to eclampsia Eclampsia •Eclampsia, also called toxemia, most serious manifestation of hypertensive disorders of pregnancy • Characterized by grand mal seizures • Often preceded by visual disturbances such as flashing lights or spots before the eyes •Eclampsia patients often experience swelling of hands & feet & markedly elevated blood pressure • If eclampsia develops, death of mother & fetus frequently results • Treat by lying mother on her side, maintaining airway, & delivering highflow oxygen Supine Hypertensive Syndrome • Supine hypotensive syndrome occurs when increased weight of uterus compresses inferior vena cava while a patient is supine • Markedly decreases blood return to heart & reduces cardiac output • Some women are predisposed to this condition because of an overall decrease in circulating blood volume or anemia Take 5. •Take a five minute break. •Enjoy this movie interlude. Remember the volume for movies comes from the computer, not the phone. •See you in five! Emergency Childbirth Usually not a big deal unless something hits the fan Signs of Imminent Delivery •Main task in evaluating expectant mother is to determine if delivery is imminent • Expose abdomen & genital area, taking care to be discrete • Visually inspect the abdominal & vaginal areas for bleeding or crowning •Prepare for immediate delivery if observe any of the following: – Crowning – Contractions less than 2 minutes apart – Rectal fullness – Feeling of imminent delivery Crowning •Crowning – appearance of any part of fetus in mother’s vagina • Remove enough of mother’s clothing to view genital region • Look for bulging at vaginal opening or a presenting part of infant Contractions •Occur at regular intervals ranging from 30 minutes to 2 minutes or less • Labor pain from contractions lasts from 30 seconds to 1 minute • As birth approaches, interval between contractions gets shorter • Contractions that occur within 2 minutes of each other, from end of one to beginning of next, signify impending delivery •Consider transporting mother if baby does not deliver after 20 minutes of contractions 2 to 3 minutes apart • Labor is generally prolonged for mother’s first baby • Average is 12 to 17 hours which allows plenty of time for transport Rectal Fullness • Rectal fullness or sensation of having to move one’s bowels can indicate infant’s head is in vagina & pressing against the rectum • Delivery is imminent • Do not let the mother sit on the toilet Feeling of Imminent Delivery • Mothers who have previously given birth often know when ready to deliver • Labor tends to be shorter after first child • Use your judgment given circumstances • When evaluating mother, keep in mind four signs of imminent delivery • Consider transport time Preparing for Delivery •• Don sterile gloves, gown, and eye protection •• Position mother on her back, legs drawn up •• Provide supplemental oxygen •• Prepare OB kit •• Prepare infant BVM •IV is optional at this point Take a look • Presentations you can’t deliver safely – Single limb – Prolapsed cord • Presentations you can deliver – – – – – Head first Umbilical cord wrapped Shoulder dystocia Breech (Buttocks first) Double footling Assisting With Delivery • • • • Support head with gentle pressure Check if cord is wrapped around baby’s neck— attempt to loosen Apply gentle downward pressure on shoulder & head After anterior shoulder has delivered, apply gentle upward pressure • Suction mouth & nostrils when head appears • Once delivered, stimulate infant if it does not breathe • Put two clamps on umbilical cord & cut 6 inches from navel Amniotic sac •During first stage of labor amniotic sac usually breaks, expelling amniotic fluid • If sac is still covering infant’s head when head appears, use a finger to pierce sac •Very tough membrane •Note color & character of amniotic fluid • Fluid can be clear or straw-colored (which is normal) • Tainted, discolored, thick or “pea soup-like” (which indicates meconium staining or a bad intrauterine infection) Detailed Delivery Instructions • Encourage the mother to breath deeply between contractions and push with contractions. • As the baby crowns, support with gentle pressure over perineum to avoid an explosive birth. • If the amniotic sac is still intact, rupture it with a finger to allow amniotic fluid to leak out. Detailed Delivery Instructions • If the umbilical cord is wrapped around the baby’s neck, gently slip it over the head. • Do not force it. • If the cord is too tight to slip over the head, apply umbilical cord clamps and cut the cord. • Clamp and cut the umbilical cord only if he baby’s head has emerged and is in a position that lows you to manage the airway. Detailed Delivery Instructions • Re-suction the baby’s mouth & nostrils • Dry & wrap baby in a warm blanket — cover its head • Place baby on its side to facilitate drainage • Perform an APGAR assessment at 1 minute & 5 minutes after delivery Infant care • Baby not breathing – stimulate it • If newborn does not start breathing effectively within 10 – 15 seconds of stimulation • Blow-by oxygen • If no response • use infant BVM to deliver gentle puffs of air — enough to cause the chest to rise • If after 30 seconds of assisted ventilation there is no response • heart rate <60 beats/min • begin CPR CPR - Two-Thumb Encircling Hands Technique CPR technique for infant with pulse rate below 60 beats/min Place infant on a firm, flat surface Remove clothing from chest Find compression site which is just below nipple line on middle or lower third of sternum Wrap your hands around upper abdomen with your thumbs on compression site Use your thumbs to deliver gentle pressure against sternum, pressing ½ to ¾ inch into chest Infant Care • If signs of meconium are present, do not stimulate infant • suction mouth & nose • This avoids aspiration of fecal material that can cause pneumonia • Good antibiotics to treat bacteria but we would rather not need to APGAR •APGAR scale – numerical measure of baby’s overall condition immediately after birth • Healthy baby will have total score of 10 • Many babies score 7 to 8 during first minute • By 5 minutes, most babies score 8 to 10 APGAR stands for: • Appearance • Pulse • Grimace • Activity • Respirations Scale Sign 0 Score 1 2 Appearance (skin, nailbeds or lips) Blue, pale Body pink, extremities blue All pink Pulse Absent <100 >100 Grimace (reflex or irritability) No response Grimaces Cries Some flexion of extremities Purposeful movement Activity (muscle tone) Respirations Limp No response Slow or irregular Strong or crying Total 1 minute 5 minute Managing a Poor APGAR Score • Three things to remember when managing infant with low APGAR score: position, suction and stimulate (PSS) – Position body so head is down & airway is open – Suction mucous & fluid from mouth & nostrils – Stimulate infant by taping bottoms of feet • PSS – memory aid to help recall these steps — position, suction and stimulate Care for mom after birth •Once baby delivered & umbilical cord cut & clamped you should: – Monitor and control bleeding from mother – Begin fundal massage – Monitor vital signs – Keep the mother and baby warm •Transport once infant is delivered • Do not wait for placenta— may take up to 30 minutes to deliver • Do not pull on umbilical cord • If placenta does deliver at scene, transport with mother & baby to hospital Care for mom after birth • After placenta delivered, place sanitary napkin between mother’s legs • Ask her to hold legs together • Normal for mother to bleed up to one cup (about 250 cc) or 5 sanitary napkins of blood after delivery • Record number of pads • Now it is time for an IV for fluid replacement Fundal Massage •Makes uterus contract & diminishes vaginal bleeding • Can feel for fundus of uterus • located in abdomen between pubic bone & umbilicus • Should feel like a softball • Perform massage like you would a muscle massage • Area may be tender & massaging it can cause discomfort •Be gentle but use some muscle Complications Field care Nuccal Cord • Once head delivered ask mother to stop pushing so you can check if cord is wrapped around infant’s neck • If cord looks like it is wrapped tightly, so as to constrict airway, need to loosen it • Gently slip cord over baby’s head by placing two fingers under cord at back of neck Nuccal Cord • Bring cord over shoulders & head • Cord durable, it can tear if handled roughly so don’t use excessive force • Too tight to loosen, clamp cord in two places two inches apart • Cut cord between clamps • Unwrap cord from around neck & take care not to injure baby Shoulder Dystocia • Labor progresses normally & head delivered routinely • However, immediately after head delivers, shoulders become trapped between symphysis pubis & sacrum, preventing further delivery • First step in treating shoulder dystocia is recognizing when it occurs • Two main signs of shoulder dystocia are: – Baby’s body does not emerge with standard moderate traction & maternal pushing after delivery of baby’s head – “Turtle Sign” –head suddenly retracts back against mother’s perineum after it emerges from vagina Buttocks & Double Footling Presentation •If buttocks or two feet present first, you can attempt delivery in field • These are generally slow deliveries & you likely have time to transport •Position mother with buttocks at edge of bed •Hold mother’s legs in flexed position • Support infant’s legs — do not pull • As head passes pubis, apply gentle upward traction until mouth appears • If head is stuck, create airway by pushing away vaginal wall — transport immediately When the head does not deliver • Create airway for infant • First, place gloved hand into vagina with your palm towards infant’s face • Form a “V” with index & middle finger on either side of infant’s nose • Push vaginal wall away from infant’s face to allow unrestricted breathing • Maintain airway & transport immediately Single limb presentation • Support baby with your hands • Provide airway for baby using your fingers if possible • Transport immediately — do not attempt delivery in field • Supportive care for mother Cord Presentation • • • • • If you see umbilical cord presenting before the baby, initiate the following steps: Place mother in kneechest position Check umbilical cord for pulsations No pulsations - press presenting part of fetus away from umbilical cord, towards mother’s head Re-check cord for pulsations • • • • • Administer high flow oxygen to mother Transport immediately – fetus will die without rapid intervention Continue holding presenting part of baby away from umbilical cord Apply moistened dressing on exposed umbilical cord Do not push umbilical cord back into vagina Summary •Key structures of female reproductive system include: – Cervix – Endometrium – Fallopian tubes – Ovaries – Perineum – Uterus – Vagina •The key structures of fetal anatomy include: – Placenta – Amniotic sac – Umbilical cord Summary • Fetus has excellent chance of survival after the seventh month of pregnancy • Pregnant women more susceptible to traumatic injury because of the increased vascularity of uterus • Patients with ectopic pregnancy often have onesided abdominal pain, late or missed period, & occasionally vaginal bleeding • Vaginal bleeding in third trimester usually caused by abruptio placenta, placenta previa, or trauma • To relieve supine hypotensive syndrome tilt the pregnant patient to one side Summary Key points for assisting with normal delivery: • Support head with gentle pressure • Check if cord wrapped around baby’s neck—if so, attempt to loosen • Apply gentle downward pressure on anterior shoulder and head • After anterior shoulder has delivered, apply gentle upward pressure on posterior shoulder & head • Suction mouth and nostrils when head appears • Once delivered, stimulate newborn if it does not breathe • Put two clamps on umbilical cord & cut 6 inches from navel Summary Care for newborn infant includes: • Stimulate infant if not breathing sufficiently • Start CPR if no response after 30 seconds • Keep infant warm • Repeat suctioning of mouth & nose • Check APGAR score at 1 & 5 minutes Summary • APGAR stands for appearance, pulse, grimace, activity, & respirations • Care of mother includes: – – – – Monitor & control bleeding from mother Begin fundal massage Monitor vital signs Keep mother & baby warm • If head remains stuck during buttocks or double footling presentation, create airway by pushing away vaginal wall then transport immediately • Important steps in caring for postpartum bleeding include fundal massage and treatment of shock Silver Cross EMS skill o’ the month! Dexi! No, not Dixie… Dexi – as in blood sugar • Should be checked on every ALS patient. – After all, we are starting IV’s anyway, so we have plenty of blood. • Should also be checked on every altered mental status, dizziness, weakness and fall. – Falling is a symptom, not a complaint. • Also, any patient who is a diabetic should have a sugar tested. • Low blood sugar is scary to have and easy to fix, that’s why we should always check for it. Testing Tips • • Of course you should always be wearing gloves. Choose a finger. – Diabetic patients will often tell you which finger they prefer. – Wipe finger with alcohol wipe, let dry completely. • Insert a test strip into your meter. – Some models like you to put the blood on the strip before testing. Know your model. • Use lancing device on SIDE of fingertip to get drop of blood. – Closer to the nail the better… people need the pads of their fingers to do stuff! – Or use whatever method you prefer to get the blood from an IV catheter. • You may have to squeeze or massage the finger to get enough blood out. – But too much squeezing/massaging can change the character of the blood. – Hold hand downward to allow gravity to help. Dexi tips continued • Touch and hold the edge of the test strip to the drop of blood, and wait for the result. • Blood glucose level will appear on the meter's display. – Many models read “hi” or “low” when sugar is below 20 or above 600. Know your meter. • Some newer meters out there let you use forearm, thigh or fleshy part of hand. • It’s OK to use the patient’s meter in a pinch, or let him/her do it, but always check with yours as well. – Patient’s glucometer may not have been calibrated lately. – Plus a lot of patients are not too good at finger hygiene… eww!
