Effectiveness of per rectal misoprostol versus intramuscular oxytocin for prevention of primary postpartum haemorrhage

Objective: To compare the effectiveness of per rectal misoprostol over oxytocin in primary postpartum haemorrhage [PPH]

---

Study Design: Randomised controlled trial study

---

Place and Duration of Study: Gynaecology and Obstetrics Department, Unit IV, Bolan Medical Complex Hospital, Quetta, from September 2013 to February 2014

---

Methodology: Emergency obstetric patients receiving per rectal misoprostol [800 micro gm] were named as group 'A' and those receiving 10 units oxytocin intramuscularly were labelled as group 'B'. The patients were followed within 24 hours of spontaneous vaginal deliveries. Pads soaked were used to assess the amount of blood loss

---

Results: A total of 1,678 patients were included in the study. The mean age of patients in group-A was 29.11 years while the mean age of patients in group-B was 29.16 years. One hundred and twenty-three [14.66%] patients in group-A and 120 [14.31%] patients in group-B had PPH. Among the total 1,678 patients, 243 [14.49%] had postpartum haemorrhage among whom 24 [9.88%] had major haemorrhage with a blood loss >/=1000 mL. Among the sub-group [839 patients] administered misoprostol had 123 [14.66%] patients with blood loss greater than 500 mL and the rest 716 patients [85.34%] had blood loss less than 500 mL. The sub-group administered oxytocin have 120 [14.31%] out of 839 patients with postpartum haemorrhage while 719 [85.69%] had blood loss less than 500 mL

Conclusion: Active management of 3rd stage of labour with per rectal misoprostol administration was as effective as intramuscular oxytocin. Both were equally effective to reduce PPH and the subsequent need for surgical interventions
