Catch! If delivery not imminent move to booked maternity unit If preterm or any complications move to nearest maternity unit Request midwife and second vehicle If any trauma or medical condition move to nearest ED Be aware supine hypotension
Frequency of contractions Pushing/expulsive noises Rupture of membranes Cervical show Vaginal bleeding Crowning
Drape everything with inco pads – its messy! Keep temperature warm Lots of towels ready As head delivers check for nuchal cord Deliver onto abdomen – beware they’re slippery Dry baby and discard wet towel No need to clamp and cut cord Transfer to nearest unit or await midwife
Birth is hypoxic event......but babies are designed to cope 1. Dry and cover baby – vigorously! 2. Assess need for intervention (APGAR) ◦ Tone, breathing and heart rate over secs 3. Open the airway – neutral position 4. 5 x inflation breaths ◦ If no chest movement reposition and repeat 5. Chest compressions if HR <60 6. Ratio CPR 3:1 and reassess every 30 seconds
Score 7-10 normal 4-7 might need some resus <4 immediate resus needed Scored at 1, 5 and 10 minutes
Transfer all to nearest obstetric unit Minor/Moderate/Major Placenta Praevia/Vasa Praevia Placental Abruption ◦ Be aware constant severe pain without bleeding Labour Post-coital Vaginal trauma/local causes Ruptured uterus esp. VBAC
This is an EXTREME EMERGENCY Bony obstruction – anterior shoulder on symphysis pubis Failure of head to deliver with routine traction on next contraction Do not pull or twist baby’s head Mc Robert’s postion Suprapubic pressure Rolling onto all fours Allow 2 attempts at delivery with each manoeuvre If not delivered immediate transfer to obstetric unit
In hospital/trained provider H – Help E – Episiotomy L – Legs into Mc Robert’s P – Pressure E – Enter manoeuvres R – Remove posterior arm R – Roll on all fours
This is also an EXTREME EMERGENCY Replace cord gently in vagina Use pad to hold in place ◦ Or keep moist with saline soaked gauze Try to avoid use of chair Lie on side with padding under pelvis Elevates the hips Disimpacts fetal head Encourage not to push Direct to nearest obstetric unit
If its not a head or a bum scoop and run! Move mother to edge of bed or sofa to use gravity Support mother’s legs – looks a bit like McRobert’s position Do not touch body or umbilical cord until nape of neck visible Only exception – baby’s spine rotates to face the floor Gently hold the pelvis and rotate so back is facing upwards Do not clamp or cut cord until head is free Once baby born gently lift feet to aid delivery of head Take care not to over-extend baby’s neck
Blood loss >500mls – can loose this in 1 minute! Primary or secondary 5% deliveries major PPH Minor <1000mls Moderate mls Severe >2000mls Major

Pre-eclampsia – hypertension and proteinuria Eclampsia – generalised tonic-clonic seizure ◦ 2.7/10,000 deliveries ◦ Usually self-limiting ◦ If seizure not stopped by 3 mins administer diazepam ◦ In hospital treated with MgSO4 Symptoms – headache, visual disturbance, epigastric pain, muscle twitching, N+V, confusion Complications – intracranial haemorrhage, renal failure, liver failure, liver capsule rupture, DIC
Treat mother as first priority Special considerations ◦ Supine hypotension – can decrease cardiac output 40% Left lateral tilt or manually displace uterus ◦ Airway oedema ◦ Increased risk aspiration ◦ Perimortem caesarean to improve CPR by 5 minutes Sepsis and VTE leading causes maternal death Manage as per underlying cause
