About

Postpartum haemorrhage (PPH) remains an important cause of maternal morbidity and mortality and it accounts for approximately 25% of all deaths worldwide. Drugs such as oxytocin, carbetocin, misoprostol, prostaglandin F2a and methylergonovine have been tested for bleeding control during and after cesarean section. Oxytocin is the most widely used agent for the prevention of postpartum hemorrhage.The primary aim of this study is to reduce the mean blood loss during cesarean section.In this study, the investigators planned to compare peroperative and postoperative blood loss levels by giving oxytocin alone to the 1st group, oxytocin and intrauterine misoprostol to the 2nd group, and carbetocin to the 3rd group of patients who were randomly divided into 3 groups.In this study, we aimed to compare the efficacy of oxytocin, misoprostol and carbetocin in preventing uterine blood loss during cesarean section.

Full description

Our prospective, randomized controlled study was conducted at the Department of Obstetrics and Gynecology of Bezmialem University Hospital between July and November 2021. The study protocol was approved by the Ethical Committee of the Medical Faculty of Bezmialem University. Written informed consent was obtained from all patients. We included a total of 156 women between 18 and 40 years of age who underwent a primary cesarean section or old 1 cesarean section under spinal anesthesia at term single pregnancy with an American Society of Anesthesiology physical status of I or II. This trial was designed and reported according to the Consolidated Standards of Reporting Trials (CONSORT) guidelines.

The patients included in this study were randomly divided into three groups by random allocation using a computer-generated random number. Group I: Oxytocin(Synpitan forte®; Deva Pharma, Istanbul, Turkey) (n = 52 )( the oxytocin infusion consisting of 20 IU dissolved in 500 mL of normal 0.9 % sodium chloride solution and infused at a rate of 125 mL/h was administered immediately after clamping the umbilical cord). Group II: (n =52) oxytocin plus intrauterine misoprostol (Synpitan forte®; Deva Pharma, Istanbul, Turkey) (the oxytocin infusion was administered immediately after clamping the umbilical cord and misoprostol tablet (400 mg) was placed into uterine cavity at the fundus after delivery of the placenta and swabbing the cavity. Group III: (n =52) 100-mg carbetocin (Synpitan forte®; Deva Pharma, Istanbul, Turkey) was intravenously administered immediately after birth of the baby. All surgeries were performed by the same team of two surgeons.. The collected data were age, prepregnancy body mass index (BMI), gravida, parity, indication of cesarean section, gestational age at birth, Apgar scores at 1 and 5 min, birth weight, neonatal intensive care unit (NICU) admission, the preoperative hemoglobin and hematocrit concentrations, the change in the hemoglobin and hematocrit concentrations (difference between preoperative and postoperative levels), operating time, intraoperative blood loss.

In this study, the investigators aimed to compare the efficacy of oxytocin, misoprostol and carbetocin in preventing uterine blood loss during cesarean section.
