Brief Summary  

This randomized, double-blind study aims to compare the effect of phenylephrine and norepinephrine infusions on coagulation during caesarean section in parturients at high risk of postpartum haemorrhage. Eighty consenting mothers undergoing caesarean section under spinal anaesthesia with risk factors such as advanced maternal age, abnormal placenta, multiple pregnancy, prior uterine surgery, previous history of  PPH or uterine anomalies will be studied. Preoperative haemoglobin and coagulation parameters will be recorded. After administration of spinal anaesthesia, phenylephrine or norepinephrine infusion will be titrated to maintain blood pressure. Post-delivery, oxytocin will be administered, and total blood loss recorded. Haemoglobin and coagulation parameters will be reassessed in the postoperative period. The primary outcome will be total blood loss.
