⚡ Massive APH (praevia/abruption)

IN REVIEWPENDING CLINICAL VERIFICATIONTIME-CRITICAL PROTOCOLFull clinical topic →
1 RECOGNIZE
  • Significant antepartum bleeding with instability or fetal compromise: resuscitate immediately; visible loss can underestimate concealed abruption.
  • Pain/tender tense uterus suggests abruption; painless bleeding may indicate praevia. Bleeding after membrane rupture with sudden fetal deterioration also raises vasa praevia.
2 CALL FOR HELP
  • Senior obstetrician, anaesthetist, blood bank, theatre and neonatal team; major-haemorrhage activation when required.
3 IMMEDIATE ACTION
  1. Resuscitate with two IV cannulae, crossmatch/blood, warming and continuous maternal monitoring. Quantify loss and assess shock rather than relying on the pad count.
  2. NO digital vaginal examination until placenta praevia is excluded or the senior team is prepared for immediate operative rescue.
  3. Continuous fetal assessment when appropriate; localise the placenta by ultrasound if it does not delay necessary birth. A normal ultrasound does not rule out abruption.
  4. If a preterm birth is likely and time/eligibility allow, choose ONE antenatal-steroid course and consider magnesium neuroprotection using the complete regimens below. Do not postpone urgent maternal/fetal delivery for their completion.

Drug doses & preparation

Choose the regimen for the stated indication. Alternatives are not instructions to give every medicine. Check prior doses, contraindications, concentration and the response before repeating.

Betamethasone — antenatal courseWHOsummary checked
Dose12 mg IM, then 12 mg IM 24 hours later
RouteIM
FrequencyTwo doses, 24 h apart
DurationOne 24 mg course. Consider only ONE repeat course under NICE criteria; not routine weekly courses
PreparationConfirm product strength: for 6 mg/mL, 12 mg = 2 mL; volumes differ by formulation. Use the obstetric IM preparation
Max dose24 mg/course; NICE permits no more than 2 courses in total under its repeat-course criteria
  • Indication: Imminent preterm birth within the guideline gestational window; do not delay urgent maternal/fetal delivery
  • NICE offers at 24+0–33+6 weeks, considers 34+0–35+6; individual discussion at 22+0–23+6. Repeat: <34 weeks, prior course >7 days ago and very high risk of birth in 48 h.
Monitoring
  • Glucose monitoring and an insulin-adjustment plan in diabetes; assess infection and timing of birth
Contraindications: Do not delay lifesaving delivery to complete steroids; do not use a blanket “infection contraindication” without senior assessment
Dexamethasone — antenatal alternativeWHOsummary checked
Dose6 mg IM every 12 h for four doses
RouteIM
FrequencyEvery 12 hours, four doses
Duration24 mg total over 36 h; ONE course, subject to the same repeat-course restrictions
PreparationCheck the injectable product: if 4 mg/mL, 6 mg = 1.5 mL; other strengths require recalculation. Give IM for this antenatal regimen
Max doseFour 6 mg doses = 24 mg/course; do not combine with a full betamethasone course
  • Indication: Alternative fetal-lung-maturation course when appropriate
Monitoring
  • Maternal glucose, infection assessment and birth timing; diabetes team plan
Contraindications: Do not prolong an unsafe pregnancy to finish the course
Magnesium sulfate — fetal neuroprotectionNICE · NG25checked
Dose4 g over 15 min, then 1 g/hour
RouteIV infusion
FrequencyLoading once, then continuous infusion
DurationStop at birth or 24 hours, whichever occurs first
Preparation50%: 4 g = 8 mL diluted in compatible sodium chloride 0.9%; maintenance example 20 g made up to FINAL 100 mL, 5 mL/hour via pump
Max dose24 hours for neuroprotection; do not add to an eclampsia regimen already running
  • Indication: Imminent preterm birth: NICE offers at 24+0–29+6 weeks and considers at 30+0–33+6 weeks; discuss 23+0–23+6 individually
Monitoring
  • Record pulse, BP, respiratory rate and tendon reflexes at least every 4 h; more often if oliguria or renal impairment
Contraindications: Myasthenia gravis, heart block or magnesium toxicity · Renal impairment or oliguria requires reduced/withheld maintenance and more frequent assessment
4 INVESTIGATIONS (never delaying treatment)
  • CBC/platelets, crossmatch, PT/APTT and fibrinogen; blood gas/lactate, calcium and renal function during major loss.
  • Ultrasound placental localisation/fetal assessment when feasible; RhD status and fetomaternal-haemorrhage testing to guide anti-D under the local gestation-specific policy.
5 DEFINITIVE MANAGEMENT
  1. Ongoing major bleeding, maternal deterioration or fetal compromise requires urgent birth and haemorrhage control. Route depends on cause and circumstances; praevia commonly requires caesarean.
  2. Abruption with fetal death and a stabilised mother may favour vaginal birth, but coagulopathy/ongoing bleeding still needs active resuscitation and senior review.
  3. Suspected accreta requires senior specialist planning; avoid forcible placental separation.
6 ESCALATION
  • Major transfusion, coagulopathy or persistent shock: theatre, blood-bank/haematology and ICU support immediately.
7 POST-EVENT CARE
  • Monitor for recurrent bleeding/DIC, renal injury and anaemia; send placenta for indicated examination.
  • Document RhD prophylaxis assessment, neonatal outcome, cause and future pregnancy/birth plan.

Admission & discharge after the acute event

Care setting: Emergency obstetric assessment; suspected acute abruption usually needs admission

Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.

This is recovery after major antepartum haemorrhage. Identify the actual cause: placenta praevia/PAS/vasa praevia and abruption need their own specialist surveillance, birth and postoperative plans.

When admission or continued hospital care is needed

  • Admit suspected abruption with pain, tenderness, bleeding, maternal instability, coagulopathy or fetal compromise; arrange timely delivery and resuscitation when indicated.

When clinic, day care or home care may be suitable

  • Abruption must not be dismissed because visible bleeding is small or absent. Home care is considered only after specialist reassessment of a resolved/uncertain presentation with a clear surveillance plan.

Before going home

  • Acute bleeding/pain and obstetric risk have been addressed; maternal blood/renal/coagulation trends and fetal or post-birth assessment support recovery.
  • No ongoing transfusion/organ-support need; the senior team has documented surveillance if the pregnancy continues.

Discharge medicines and treatment changes

  • Reconcile anaemia treatment and any indicated post-birth VTE prevention against current bleeding risk. Acute haemorrhage medicines are not routine take-home treatment.

Tests, pending results and their reviewer

  • Communicate blood loss, Hb/platelets/coagulation/renal findings and the plan for abnormal results.

Home care and counselling

  • Explain recurrence risks, future-pregnancy specialist review and urgent-return symptoms; support bereavement if relevant.

Follow-up: when and what to review

WhenAction / responsible service
Before discharge
Agree obstetric/fetal monitoring if still pregnant, or early postnatal and anaemia reviews after birth.
Postnatal/future-pregnancy review
Review hypertension, placental-risk factors, recovery and prevention planning.

Return urgently

  • Recurrent bleeding, abdominal pain, reduced movements, collapse, dyspnoea or fever require immediate hospital care.
