This study conducted a systematic review and meta-analysis to compare the antihemorrhagic efficacy and safety of tranexamic acid (TXA) and misoprostol in the management of postpartum hemorrhage (PPH). The results showed no significant difference between TXA and misoprostol in terms of antihemorrhagic efficacy and safety.
Aim: To conduct the first-ever systematic review and meta-analysis of randomized controlled trials (RCTs) on the antihemorrhagic utility and safety of tranexamic acid (TXA) versus misoprostol for management (prevention and/or treatment) of postpartum hemorrhage (PPH).Methods: Six databases were screened from inception until May 2023 and updated in September 2023. The RCTs were assessed for quality according to the Cochrane's risk of bias tool. The endpoints were summarized as mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI) in a random-effects model.Results: Ten RCTs with 2121 patients (TXA = 1061 and misoprostol = 1060) were analyzed. There was no significant difference between TXA and misoprostol groups regarding the mean intraoperative blood loss (n = 9 RCTs, MD = 17.32 ml, 95% CI [-40.43, 75.07], p = 0.56), mean change in hemoglobin (n = 6 RCTs, MD = 0.11 mg/dl, 95% CI [-0.1, 0.31], p = 0.30), mean hospital stay (n = 2 RCTs, MD =-0.3 day, 95% CI [-0.61, 0.01], p = 0.06), blood transfusion rate (n = 4 RCTs, RR = 0.49, 95% CI [0.16, 1.47], p = 0.2), and rate of additional uterotonic agents (n = 4 RCTs, RR = 1.05, 95% CI [0.72, 1.53], p = 0.81). Leave-one-out sensitivity analysis showed robustness of the results, and there was no evidence of publication bias. Regarding safety endpoints, there was no significant difference between both groups regarding the rates of minor side effects, such as diarrhea, fever, nausea, and vomiting. No patient developed thromboembolic events in the TXA group.Conclusion: There was no significant antihemorrhagic efficacy between adjunct TXA and misoprostol for the management of PPH. The safety profile was comparable between both agents.
