RESUMO
Prevention of postpartum haemorrhage has been a major issue for its life threatening impact on maternal morbidity and mortality worldwide. Conventional continuous infusion of oxytocin has been employed for this condition. Apparently, in place of conventional oxytocics, application of carbetocin with longer half-life shows the same clinical benefits. This requires doing this present study. To compare the effectiveness of I/V bolus cabetocin and oxytocin infusion used for prevention of primary PPH after caesarean section. This descriptive cross-sectional comparative study was carried out in Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from November 2015 to April 2016. A total of 100 pregnant women undergoing elective or emergency caesarean section were enrolled and divided into two groups on the basis of exclusion and inclusion criteria. Group I (n=50) received bolus of 100µgm IV carbetocin after delivery of the baby & Group II (n=50) received 20 IU of oxytocin in 1000ml of Hartman solution I/V in 8 hours continuous infusion after delivery of the baby. Baseline demographic and obstetric profile, indications for C/S, estimated blood loss, hemoglobin level, additional uterotonic agents, blood pressure and the diuresis were compared immediate postoperatively and 24 hours after operation. The patients were followed up for 24 hours after operation regarding outcomes variables. Baseline profiles were similar between two groups. Regarding haemodynamic effects, both drugs have a hypotensive effect but a greater reduction in blood pressure is found in oxytocin group. There was no significant difference in respect of estimated blood loss, blood transfusion, additional oxytocics and diuresis between two groups. It can be concluded that a single injection of carbetocin is as effective as continuous oxytocin infusion to prevent postpartum haemorrhage, with similar haemodynamic profile. So, carbetocin as a uterotonic agent is an acceptable alternative for prevention of postpartum haemorhage after caesarean section.
