π§ FREE MSRA PODCAST β Postpartum Haemorrhage (PPH): Key Revision Insights
Postpartum haemorrhage (PPH) is one of the most critical emergencies in obstetrics and a must-know for any MSRA candidate. In this episode, we break down the absolute essentialsβdefinition, causes (including that classic β4 Tsβ mnemonic), investigations, management, prevention, and complications. Listen in for high-yield revision and clinical pearls that stick!
π Key Learning Points
π©Έ Definition & Types
β’ PPH = Excessive bleeding after birth: >500 ml after vaginal delivery, >1,000 ml after caesarean.
β’ Primary PPH: within 24 hours post-delivery. Secondary PPH: 24 hours to 6 weeks after delivery.
π‘ Causes: Remember the 4 Ts!
β’ Tone (uterine atony β most common)
β’ Trauma (tears or lacerations)
β’ Tissue (retained placenta/clots)
β’ Thrombin (coagulation disorders)
β’ (Secondary PPH: think infection/endometritis, retained products)
β οΈ Risk Factors
β’ History of PPH, prolonged labour, multiple pregnancies, large baby (macrosomia), polyhydramnios, preeclampsia, placenta praevia, C-section, manual placenta removal, anaemia.
π©Ί Clinical Picture & Diagnosis
β’ Excessive vaginal bleeding (soaking >1 pad/hour), passing clots, signs of shock (tachycardia, hypotension, pallor, dizziness), boggy uterus (atony), fever/pain (suggesting infection in secondary PPH).
π Investigations
β’ FBC (Hb, Hct), clotting screen, blood group & cross-match, blood cultures (if infection), MSU & high vaginal swab (if secondary PPH).
β’ Ultrasound: helpful for retained tissue (thin endometrial stripe = unlikely RPOC); not reliable for endometritis.
π¨ Management β 4 Key Steps
Communication: Alert team (obstetricians, anaesthetists, blood bank, porters)
Resuscitation: 2 large-bore IVs, O2, fluid resus, cross-match for blood
Monitoring: Vital signs, urine output, repeat bloods
Arrest the bleeding: Uterine massage, uterotonics (oxytocin Β± ergometrine), balloon tamponade, B-Lynch suture, arterial ligation, embolisation, hysterectomy if severe/uncontrolled
π¦ Secondary PPH:
β’ Treat infection (IV antibiotics), evacuate retained products if needed, correct anaemia with iron.
π‘οΈ Prevention
β’ Active management of third stage (give oxytocin): reduces PPH risk by ~60%
β’ Identify at-risk women, plan delivery in appropriate setting.
π Complications
β’ Severe anaemia, transfusion reactions, DIC, sepsis, multi-organ failure, AKI, liver failure, ARDS, and death (if untreated).
