Postpartum haemorrhage refractory to first-line drugs in a woman who wants more children
A 31-year-old G3P2 has a spontaneous vaginal birth at 39 weeks after a 9-hour labour and active third stage. Estimated blood loss is 1200 mL at 10 minutes and ongoing. She is pale, BP 96/58, pulse 118, and has received oxytocin 10 IU IM, an oxytocin infusion, ergometrine 250 mcg IM and carboprost 250 mcg IM. The uterus remains soft and fundal massage produces only partial contraction. She has one intravenous cannula, 1 unit of packed cells running, and no crossmatched blood yet. Her booking bloods were group O negative, Hb 118, and she has no comorbidities. She tells you she wants more children.
1. Set out your next steps in order of priority, including drugs, resuscitation and mechanical measures.

This is a major primary postpartum haemorrhage with uterine atony and maternal compromise (tachycardia, hypotension).
Resuscitation first:
- Call for help: senior obstetrician, anaesthetist, haematologist, porter and blood bank. Use a massive haemorrhage protocol.
- Second large-bore cannula, warmed crystalloid cautiously, and urgent crossmatched blood; give O-negative units if crossmatch is not available. Group O negative means she can receive O-negative or, once crossmatched, her own group.
- Send full blood count, coagulation profile, fibrinogen, urea and electrolytes and crossmatch; repeat every 30-60 minutes.
- Give tranexamic acid 1 g IV over 10 minutes as soon as possible (within 3 hours of birth), and consider a second dose.
- Keep her warm, monitor urine output, and consider a urinary catheter.
Drugs and mechanical measures:
- Misoprostol 800 mcg sublingually or 600 mcg orally can be added; carboprost can be repeated up to the maximum dose (usually 8 doses of 250 mcg) if no asthma.
- Bimanual uterine compression, then intrauterine balloon tamponade (e.g. Bakri) while arranging theatre.
- If these fail, transfer to theatre for examination under anaesthesia, evacuation of retained products, and laparotomy with compression sutures (B-Lynch) or vessel ligation, with hysterectomy as the last resort.
- Consider interventional radiology if available and the patient is stable enough.
Document times, drugs, doses and responses.
2. She is RhD-negative. What specific additional management is required, and why does timing matter?
Read the worked answer
She needs anti-D immunoglobulin because a large fetomaternal haemorrhage is likely with a major postpartum haemorrhage and manual interventions.
- Standard antenatal and postnatal anti-D prophylaxis is 500-1500 IU depending on local protocol; after a sensitising event or large bleed, give at least 500 IU and perform a Kleihauer-Betke or flow cytometry test to quantify fetomaternal haemorrhage.
- If the Kleihauer shows more than the standard dose covers (roughly 4 mL of fetal red cells per 500 IU in many protocols), give additional anti-D calculated from the result. Local protocols vary, so follow the unit's guideline.
- Give anti-D as soon as possible after delivery; it is most effective within 72 hours but should still be given up to 10 days if delayed.
- Check that she has not already formed anti-D; if she is already sensitised, anti-D is not useful and the focus shifts to monitoring any future pregnancy.
- Record the dose, batch and Kleihauer result, and ensure the result is communicated to her and her GP.
Timing matters because prophylaxis works by clearing fetal cells before the immune system mounts a response; once sensitised, the risk to future pregnancies is permanent.
3. If bleeding is controlled with a balloon and she recovers, what follow-up and future-pregnancy advice do you give?
Read the worked answer
Follow-up:
- Continue observation for at least 24 hours after the event, with repeat haemoglobin and iron studies; treat anaemia with iron and consider transfusion if symptomatic.
- Consider thromboprophylaxis once bleeding has stopped, balancing the risk of venous thromboembolism against ongoing bleeding.
- Screen for Sheehan syndrome only if there are symptoms; routine testing is not needed, but advise her to report failure of lactation, fatigue or amenorrhoea.
- Offer debriefing and written information; screen for postnatal depression and post-traumatic stress.
Future pregnancy:
- Recurrence of postpartum haemorrhage is increased (roughly 15-25% after atonic haemorrhage), so plan delivery in a unit with blood products and senior cover.
- Document the cause and the interventions used; the next pregnancy should have an individualised third-stage plan, active management, and early recognition of bleeding.
- Correct anaemia before conception and in early pregnancy.
- Discuss contraception and interpregnancy interval; she wants more children, so avoid sterilisation unless she requests it.
- Ensure she knows to report heavy bleeding or symptoms of anaemia.
