Q

Method of IOL

A

Antenatal ward under care of midwifes
Move to labour ward when in active labour

Membrane sweeping before induction (from 40 weeks) - releases prostaglandins

  1. Vaginal prostaglandin (tablet/gel 2 doses 6 hours apart, pessary 1 over 24 hours). Cervical ripening balloon can avoid uterine hyperstimulation.
  2. Amniotomy
  3. IV syntocinon (2 hours after rupture if labour has not ensued)

If failed, rest and attempt again or C-section

• Examination - lie, presentation, SFH

  • LFTs
  • Bile acids
  • PT
21
Q

Obstetric cholestasis counselling

A
  • Slow down of bile through the liver, build up, and leakage into bloodstream causing symptoms (unsure why - hormonal? genetic?)
  • RF of FHx, previous Hx, multiple pregnancy

• Offer IOL at 37 weeks and deliver on labour ward with continue CTG monitoring, due to risk of stillbirth

  • Weekly LFTs and bile acid levels
  • Wear cool, loose clothing
  • Pay attention to foetal movements
  • Symptomatic treatment: ice packs, emollients, ursodeoxycholic acid

• High recurrence rate

A 
Beside, bloods, imaging approach
• Obs

Admit and involve the MDT - call for senior obstetrician, call 2222 for major obstetric haemorrhage protocol

ABCDE
• Gain IV access
• Bloods if haven't done that yet as acute
• Give anti-D in Rh-negative women
• Continuous fetal monitoring

Placental abruption management

A

Admit and involve the MDT - call for senior obstetrician, call 2222 for major obstetric haemorrhage protocol

ABCDE
• Gain IV access
• Bloods if haven't done that yet as acute
• Give anti-D in Rh-negative women
• Continuous fetal monitoring
  • Haem unstable/foetal distress- deliver
  • Stable: <37 - steroids, admit to antenatal ward, discharge with weekly serial growth scans, >37 - IOL

• Obs
• Examination - cardio, resp, preg abdo

• FBC, ABG, coagulation screen

  • DVT: Compression duplex USS - if positive start treatment
  • PE and no DVT: V/Q lung scan or CTPA
27
Q

VTE/PE management

A

Admit if PE. Involve the MDT - senior obstetrician, radiologists, anaesthetists, midwives.

  • SC LMWH immediately
  • Titrate to booking weight and use throughout pregnancy until 3 months postpartum
  • Teach how to use injections daily
  • Stop 24 hours before delivery or once in labour
28
Q

Postpartum haemorrhage investigations/management

A
  • Abdo exam
  • Vaginal exam (speculum)

I would like to involve the MDT by calling for help for the senior obstetrician, anaesthetist, senior midwife and porter. I’d pull the alarm behind the hospital bed and call 2222 for Major Obstetric Haemorrhage Protocol.

An ABCDE investigative approach would then be started concurrently with management. Would ensure:
• O2 by mask
• 2x 14 gauge peripheral cannulae
• Cross-match 6 units of bluid and inform the haem team
• Foley catheter into bladder and fluid balance chart
• Blood transfusion
• Anti-D if rhesus negative

Mechanically:
• Bimanual compression
• Intrauterine balloon tamponade
• MROP
• Clamp ligation of uterine or internal iliac arteries
• Surgical repair for trauma

Medically:

  1. IV syntometrine or IV syntocinon (if HTN/asthma)
  2. IM carboprost (increases uterine tone)
  3. IV tranexamic acid

ABx for secondary PPH (>24 hours after birth) e.g. endometritis

Hysterectomy if severe uncontrolled haemorrhage (2 seniors to make decision)

29
Q

SGA/IUGR investigations

A
  • Obs
  • Abdo exam - SFH, lie
  • Urine dip
  • Doppler
  • CTG
30
Q

IUGR management

• Doppler USS 2x a week
• Advise mother to monitor foetal movements

Delivery
• Aim for 37 weeks
• Immediate delivery if abnormal CTG + RFM, or abnormal doppler

31
Q

Shoulder dystocia management

A

Obstetric emergency - call for senior obstetric help and neonatal paediatric team.
Tell mother to stop pushing.

  1. McRobert’s manoeuvre: flexion and abduction of hips
  2. Suprapubic pressure to improve manoeuvre
  3. Internal rotation (consider episiotomy)
    - Rubins manoeuvre: pressure on anterior aspect of baby’s shoulder
    - Wood’s screw manoeuvre: insert other hand on posterior aspect of shoulder to aid (4) for 180-degree rotation
  4. Deliver posterior arm
  5. Change position to all fours
  6. Foetal cleidotomy, maternal symphisiotomy, or Zavanelli followed by C-section
