Carbetocin versus oxytocin in prevention of postpartum hemorrhage after cesarean delivery in high-risk women. A systematic review and meta-analysis
Abstract
Objectives: To assess the value of carbetocin in prevention of postpartum hemorrhage (PPH) after Cesarean delivery (CD).
Search strategy: Screening of PubMed, Web Of Science, Scopus, register clinical trials registry and Google scholar from inception to December 2023. The keywords used included postpartum hemorrhage, intraoperative blood loss, postoperative blood loss, Cesarean delivery and their MeSH terms.
Selection criteria: All RCTs that compared carbetocin to oxytocin in women undergoing CD with risk factor for PPH. Fourteen studies including 3068 participants. Thirteen were written in English and one in Polish.
Data collection and analysis: The extracted data included location of the trial, number of centers involved in recruitment, the number of participants and their characteristics, details of the study groups and dose time and route of intervention and its comparator, primary and secondary outcome parameters and trial registration number and timing in relation to patients recruitment. The evaluated outcomes parameters included intraoperative and 1st 24 h post-operative blood loss, PPH, the hemoglobin changes after the procedure, the need for any additional uterotonic agents, surgical interventions or blood transfusion and drugs side effects.
Main results: Blood loss during the 1st 24 h after CD was evaluated in 11 studies with 2497 participants and revealed a mean difference (MD) of -111.07 with 95% CI of [-189.34 and -32.80 (P = 0.005, I2 97%). The hemoglobin…
