Efficacy of Four Different Treatment Regimes on Postpartum Hemorrhage

This prospective, randomized controlled study was conducted at the Department of Obstetrics and Gynecology of Bezmialem University Hospital and Van Regional Training and Research Hospital between August 2022 and February 2023. The study protocol was approved by the Ethical Committee of the Medical Faculty of Bezmialem University. Written informed consent was obtained from all patients. Investigators included a total of 272 women between 18 and 40 years of age who came to hospital for vaginal delivery at term single pregnancy. 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 four groups by random allocation using a computer-generated random number. Group I: carbetocin (Pabal®; Ferring Pharma, Istanbul, Turkey) (n = 68 )(was intravenously administered immediately after birth of the baby). Group II: Oxytocin(Synpitan forte®; Deva Pharma, Istanbul, Turkey) (n =68)(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 III: carbetocin and tranexamic acid (Transamin; TEVA Pharma, Istanbul, Turkey)2 (n =68) (100-mg carbetocin was intravenously administered immediately after birth of the baby and tranexamic acid infusion consisting of 1gr dissolved in 100 mL of normal 0.9 % sodium chloride solution was administered immediately after clamping the umbilical cord) . Group IV: oxytocin and tranexamic acid (n=68) (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 and tranexamic acid infusion consisting of 1gr dissolved in 100 mL of normal 0.9 % sodium chloride solution was administered immediately after clamping the umbilical cord).The collected data were age, prepregnancy body mass index (BMI), gravida, parity, gestational age at birth, Apgar scores at 1 and 5 min, birth weight, neonatal intensive care unit (NICU) admission, the prepartum hemoglobin and hematocrit concentrations, the change in the hemoglobin and hematocrit concentrations (difference between prepartum and postpartum levels), duration of delivery stages, intrapartum blood loss and estimated blood loss after 2 hours of vaginal delivery. In this study, the investigators aimed to compare the efficacy of oxytocin, carbetocin and tranexamic acid in preventing uterine blood loss during vaginal delivery.
