A Systematic Review And Meta-Analysis Of The Effect Of Prophylactic Tranexamic Acid Treatment In Major Benign Uterine Surgery
INTERNATIONAL JOURNAL OF GYNECOLOGY & OBSTETRICS(2017)
摘要
Background: The value of tranexamic acid ( TA) treatment as bleeding prophylaxis in major uterine surgery is unclear.Objectives: To evaluate the antihemorrhagic effect of prophylactic TA treatment in major benign uterine surgery.Search strategy: PubMed, Embase, Cochrane Library, and Web of Science were searched from 1980 to 2015 without language restriction using search terms related to major uterine surgery combined with TA.Selection criteria: Randomized controlled trials comparing prophylactic TA with placebo or no intervention in women undergoing elective major benign uterine surgery.Data collection and analysis: Basic information and outcomes were collected and meta-analyses performed.Main results: Sixteen trials were included, with five trials considered to have an overall low risk of bias. In cesarean delivery, TA significantly reduced intraoperative bleeding ( mean -136 mL, 95% confidence interval [ CI] - 189 to -83), blood loss of more than 1000 mL (relative risk 0.38, 95% CI 0.18-0.81), and blood transfusion (relative risk 0.32, 95% CI 0.17-0.59). In abdominal myomectomy, TA also significantly reduced intraoperative bleeding (mean - 251 mL, 95% CI - 391 to - 110).Conclusions: Prophylactic TA treatment significantly reduced operative bleeding in women undergoing elective cesarean delivery or abdominal myomectomy. Additional randomized trials with low risk of bias are needed.
