Luton and Dunstable NHS Foundation Trust Intrapartum Care Pathway HB, MC, KC Aug 2011 V1 1 INTRODUCTION The Intrapartum Care Pathway has been developed to provide evidence based guidance for midwives leading care of normal women during labour and the immediate post birth period. The pathway focuses on the following aspects of intrapartum care: First stage of labour Second stage of labour Third stage of labour - physiological - active Care of mother and baby in the first hour after birth The woman’s journey through her intrapartum care is depicted through a series of flow diagrams, which are underpinned by philosophies and principles of care. Guidance notes are also provided to support midwives’ use of the flow diagrams. A red, amber, green (RAG) trigger system is incorporated throughout the intrapartum care pathway in order to aid midwives’ clinical decision making. Green = continue midwifery led care and progress along normal birth pathway Amber = continue midwifery led care but consider and employ as necessary, alternative midwifery actions that may be needed to continue along normal birth pathway Red = transfer to consultant led care Philosophy of caring for women in labour To promote the physiological processes of birth and reduce medical interventions in labour To increase the number of women experiencing normal birth outcomes To reduce the rate of instrumental births and caesarean sections To increase satisfaction with the birth experience for women and families Principles of Care for women in 1st Stage of Labour Birth environment - relaxed, private, safe Low technology and one to one support from a health professional and birthing partner(s) Discuss and support women’s birth plans Midwives are able to offer options for non pharmacological and pharmacological pain relief and support women in their choice Support eating and drinking in labour. Encourage women to bring isotonic drinks HB, MC, KC Aug 2011 V1 2 Maternal Monitoring Abdominal palpation for descent and position on admission and prior to vaginal examination Offer vaginal examinations on admission and 4 hourly to assess progress in labour Palpation and assessment of uterine contractions half hourly Continuous assessment of pain Continuous assessment of colour of PV loss Maternal observations: 4 hourly Temperature and BP, hourly pulse Refer to local guidance on observations if labouring in water Encourage regular bladder emptying 3-4 hourly Fetal monitoring Intermittent auscultation of the fetal heart rate (FHR) is recommended for low-risk women in established labour in any birth setting There is no evidence to support admission CTG in healthy women with no complications Normal fetal heart rate should be between 110-160 bpm on auscultation Intermittent auscultation for 1 minute every 15 minutes after a contraction Be aware of a rising or changing FHR as an indicator of potential fetal compromise and consider changing to Electronic Fetal Monitoring Reference Care of the Woman in Labour (CG114) MLBU operational Policy (CG287) HB, MC, KC Aug 2011 V1 3 PATHWAYS FOR MIDWIFERY LED CARE – 1ST STAGE OF LABOUR Is the woman suitable for midwifery led care?

If birth is not imminent after one hour of active second stage there must be a discussion with the senior midwife and the obstetrician Reference: NICE Intrapartum care (2008) Reference: NICE Intrapartum care (2008) 8 PRINCIPLES OF CARE FOR WOMEN IN 3RD STAGE OF LABOUR Birth environment - relaxed, private, safe Support women’s choice for either physiological or active management of 3 rd stage of labour Assess maternal observations Check placenta and membranes for completeness Record estimated blood loss Maintain accurate contemporaneous records Physiological 3rd Stage Ensure informed maternal consent Do not clamp and cut the cord unless clinically indicated Offer and encourage skin to skin contact Await signs of separation Await maternal urge to push or visibility of placenta at vulva Do not interfere with the fundus or pull the cord Physiological 3rd stage should be complete within 60 minutes Active management is recommended at 60 minutes Active management of 3rd stage Ensure informed maternal consent Administer Syntometrine IM as soon after delivery of the anterior shoulder as possible Offer and encourage skin to skin contact Clamp and cut the umbilical cord after birth Await signs of separation ( should occur within 15 minutes) Deliver the placenta by controlled cord traction Reference Care of Woman in labour (CG114) 9 PATHWAYS FOR MIDWIFERY LED CARE – PHYSIOLOGICAL 3rd STAGE OF LABOUR Offer skin to skin contact and encourage breastfeeding Await signs of placental separation ( usually within 60 minutes) Placenta visible at vulva and/or strong urge to push Placenta delivered by maternal effort Assess maternal observations Check placenta and membranes are complete No signs of placental separation within one hour of birth Encourage breastfeeding/nipple stimulation Change maternal position ( preferably to an upright position) Ensure bladder empty ( if in doubt, empty the bladder with an intermittent catheter) Observe maternal condition No signs of placental separation after one hour of birth Transfer to active management of 3rd stage of labour pathway (following which, if placenta not delivered within 30 minutes, transfer to consultant led care) 10 PATHWAYS FOR MIDWIFERY LED CARE – ACTIVE MANAGEMENT OF 3RD STAGE OF LABOUR Administer one ampoule of intramuscular Syntometrine as soon as possible after the delivery of the anterior shoulder Offer skin to skin contact Clamp and cut the umbilical cord Await signs of placental separation (usually within 15 minutes) Deliver placenta by controlled cord traction Assess maternal observations Check placenta and membranes are complete No signs of placental separation Encourage breastfeeding/nipple stimulation Change maternal position ( preferably to an upright position) Ensure bladder empty ( if in doubt, empty the bladder with an intermittent catheter) Assess for signs of separation within 30 minutes No signs of placental separation within 30 minutes Observe maternal condition Transfer to consultant led care 11 PATHWAYS FOR MIDWIFERY LED CARE – 3rd STAGE NOTES Definition of 3rd stage of labour: The time from birth of the baby to the expulsion of the placenta and membranes. Management of the third stage of labour should be chosen by the woman following discussion and an informed decision. Physiological 3rd stage is only suitable for low risk women Physiological 3rd stage is the natural conclusion to a physiological 1st and 2nd stage of labour. It involves a pathway of care which includes the following three components: No routine clamping and cutting of the umbilical cord No clamping of the cord until at least pulsation has ceased ( unless clinically indicated) Delivery of placenta by maternal effort No pulling the umbilical cord or palpation of uterus Active management of 3rd stage involves a pathway of care which includes the following three components: Routine use of oxytocic drugs Clamping and cutting of the umbilical cord following birth of the baby Delivery of placenta by controlled cord traction Reference: NICE Intrapartum care (2008) Predisposing factors to post partum haemorrhage History of Post partum haemorrhage Previous retained placenta Multiple pregnancy Grandmultiparity Abnormalities of the placenta Coagulation abnormalities Anaemia ( Hb less than 8.5 at onset of labour) Ketoacidosis Polyhydramnios Fibroids Antepartum haemorrhage Prolonged first stage of labour Prolonged second stage of labour Prolonged third stage of labour Precipitate labour Shoulder Dystocia Instrumental birth Raised BMI ( greater than 35 kg/m2) Maternal age ( greater than 35 years) This is not an exhaustive list. Any identification of a risk factor for PPH indicates active management of 3rd stage of labour Reference: NICE Intrapartum Care (2008) 12 PRINCIPLES OF CARE FOR WOMEN AND BABIES IN THE FIRST HOUR AFTER BIRTH Post Birth environment - relaxed, private, safe, unhurried Maternal Monitoring Assess maternal observations Assess involution of the uterus Assess perineal trauma Advice regarding immediate management of perineal trauma Meet personal hygiene needs Ensure adequate hydration and nourishment Ensure successful voiding of bladder Neonatal monitoring Assess neonatal well being and identify any resuscitative measures required Facilitate one hour of uninterrupted skin to skin contact as soon as possible after birth Initiate infant feeding in first hour after birth Maintain infant’s body temperature Identify and label infant in line with local guidance Ensure initial examination of the infant is undertaken Administer Vitamin K based on informed decision of parents Reference: Care of the woman in labour (CG114) The promotion, protection and support of breastfeeding within the Luton and Dunstable NHS Foundation trust (CG12) Identification of babies Definition and repair of perineal tear (CG131) 13 PATHWAYS FOR MIDWIFERY LED CARE – Mother’s 1st hour Skin to skin contact Maternal observations Temperature Pulse Blood pressure Fundal palpation Blood loss General physical condition Assess emotional/physchological condition Examine placenta and membranes Normal observations Inspect vulva,vagina and perineum to assess trauma Intact perineum Ensure hydration and nutrition needs met Ensure personal hygiene needs met Measure first void Continue to postnatal pathway Perineal tear classified as 1st or 2nd degree and repaired as required Perineal tear classified as 3rd or 4th degree Observations outside of normal range Consider: Measures to reduce temperature/pulse Analgesia Empty bladder Stimulate a contraction Observations continue to be outside of normal range Implement obstetric early warning score system Transfer to consultant led care 14 PATHWAYS FOR MIDWIFERY LED CARE –Baby’s 1st hour Skin to skin contact Assess baby’s wellbeing using Apgar score at 1 and 5 minutes Initiate and support chosen method of feeding Initiate resuscitation and call for assistance if indicated Complete two neonatal identification bands. Confirm details with parents Secure identification bands to baby’s ankles (hospital only) Undertake initial examination of the newborn Weigh the baby Measure head circumference Discuss findings with the parents Deviation from normal identified at newborn examination Give unbiased information to enable informed choice about neonatal Vitamin K administration. Administer neonatal Vitamin K by chosen route Continue to postnatal pathway Vitamin K declined Refer to neonatologist 15 PATHWAYS FOR MIDWIFERY LED CARE – MOTHER AND BABY’S FIRST HOUR NOTES In the initial post birth period: Ensure maternal and infant physical wellbeing Do not separate mother and newborn in the first hour after birth Support women in the immediate care of the newborn Promote maternal/infant emotional connection Support infant feeding choice Measure maternal first void of urine Ensure women who have sustained perineal trauma make an informed decision regarding repair Competent midwives can suture perineal trauma that meet the following definitions: First degree – injury to skin only Second degree – injury to the perineal muscles but not the anal sphincter Episiotomy o o Women should be advised that: Reference: NICE Intrapartum care (2008) First degree tear should be sutured to improve healing unless the skin edges are well opposed Second degree tear should have the muscles sutured to improve healing. If the skin is well opposed it may not require suturing Perineal repair should only be undertaken with tested effective analgesia A continuous non locked suturing technique should be used for the vaginal wall and muscle layer A continuous subcuticular technique should be used for the skin An absorbable synthetic suture material should be used Third degree – injury to the perineum involving the anal sphincter complex o 3a – less than 50% of the external anal sphincter thickness torn 3b – more than 50% of the external anal sphincter thickness torn 3c – internal anal sphincter torn Fourth degree - injury to the perineum involving the anal sphincter complex and anal epithelium Third and fourth degree perineal tears must be sutured by a competent obstetrician Reference: NICE Intrapartum care (2008) Reference: NICE Intrapartum Care (2008) 16
