A retrospective cohort study of twin pregnancies in Hong Kong has identified general anaesthesia (GA) and use of oxytocin as significant risk factors for all postpartum haemorrhage (PPH; ≥500 mL). The study also shows that GA, in vitro fertilization (IVF), antepartum haemorrhage, placental abruption, and placenta praevia (PP) are significantly associated with major PPH (>1,000 mL), while IVF, PP, and obesity are significant risk factors for severe PPH (>1,500 mL).
