ABSTRACT Objective:To compare the efficacy and safety of phloroglucinol and magnesium sulfate in threatened abortion by adopting the method of systematic evaluation. Methods:The Cochrane Library, PubMed, Embase, SinoMed, CNKI, VIP and WanFang Data were electronically searched to collect randomized controlled trials (RCTs) of phloroglucinol and magnesium sulfate in the treatment of threatened abortion from inception to May 2018. Two researchers independently conducted literature screening, data extraction and assessed the risk of bias of included studies evaluation. Stata 12.0 software was used for Meta analysis.Results: A total of 21 RCTs involving 1 940 patients were included, and the quality of the included studies was not high. The result of Meta analysis showed that the total effective rate (RR=1.12, 95%CI1.08 to 1.17, P<0.001) and onset time of phloroglucinol (SMD=0.25, 95%CI 0.09 to 0.41, P=0.002) in the treatment of threatened abortion were higher than those of magnesium sulfate, and the remission time of uterine contraction (SMD=-0.22, 95%CI -0.39 to 0.05, P<0.001), incidence of flush fever (RR=0.09, 95%CI0.05to 0.16,P<0.001), incidence of dizziness and headache (RR=0.15, 95%CI 0.08 to 0.28, P<0.001), incidence of gastrointestinal discomfort (RR=0.19, 95%CI 0.10 to 0.36, P<0.001) and the complete disappearance time of uterine contraction symptoms (SMD=-2.08, 95%CI -3.05 to -1.12, P<0.001) were lower than those of magnesium sulfate. Conclusion:Phloroglucinol is superior to magnesium sulfate in the treatment of threatened abortion with significant reduced incidence of adverse reactions. However, in consideration of the low quality of evidence, larger sample, multi center, high quality studies are still needed to verify. |
