摘要:
Objective:To systematically review the clinical efficacy and safety of application of mifepristone combined with misoprostol vaginal medication for termination of second trimestic.Methods:The database of Pub-Med,the Cochrane library,CBMdisc,FMJS,VIP,Wanfang and CNKI were searched from inception to Sep.2017.Randomized controlled trials(RCTs)of termination of second trimestic by mifepristone combined with misoprostol vaginal medication(group B) or by rivanol amniotic cavity injection(group A) were reviewed and evaluated.Rev Man5.3 software was used for Meta analysis.Results:Eighteen RCT with 3,216 patients were eligible and included in the systematic review.Meta analysis showed that the group B was significantly superior to the group A in the time of launching uterine contraction,fetal delivery and total duration of labor (P<0.00001,WMD =-0.65,95%CI-0.76,-0.54;P<0.00001,WMI-0.77,95%CI-0.86,-0.68;P<0.00001,WMD =0.63,95%CI 0.48,0.73),improved success rate of termination of second trimestic(P 0.000 5,WMD=-10.50,95%CI-16.46,-4.55),and decreased theincomplete abortion rate (Z =4.21,P<0.00001,95 %CI0.42,0.73).There was no significant differences in the amount of vaginal bleeding within 24 hours after delivery between two groups(P=0.09,WMD =-0.66,95%CI-1.42,0.11).The incidence of nausea,vomiting and gastrointestinal symptoms of women in group B were significant higher than those of women in group A (Z =11.87,P < 0.00001,95%CI 11.62,30.65).Conclusions:Mifepristone combined with vaginal misoprostol for termination of secondtrimestic is more efficacy than the intra-amniotic injection of rivanol,which has lower rate of tissue residues,dilation and curettage of uterus,less blood loss,lower rate of cervico-vaginal injury.It is a safe and ef fective method for termination of mid-term pregnancy.However,due to the limitations of the number and quality of the literature included in the system evaluation,more rigorous evidence is needed.%目的:系统评价米非司酮联合米索前列醇阴道用药终止中期妊娠的疗效与安全性.方法:检索Pub Med、Cochrane图书馆、中国生物医学文献数据库、西文生物医学期刊文献数据库、万方数据库、维普中文科技期刊数据库和中国知网(CNKI),检索时限均从建库至2017年9月,收集米非司酮联合(配伍)米索前列醇为主要方法终止中期妊娠的随机对照试验(RCT),进行文献筛选及质量评价,采用Rev Man5.3软件进行统计分析.结果:共18篇文章,3216例妇女符合纳入标准进入研究.meta分析结果表明,米非司酮联合米索前列醇与传统依沙吖啶羊膜腔内注射相比,能明显缩短宫缩发动时间、总产程及胎儿排出时间(P<0.00001,WMD=-0.65,95%CI-0.76~-0.54;P<0.00001,WMD =-0.77,95%CI-0.86~-0.68;P<0.00001,WMD =0.63,95%CI 0.48~0.73),提高引产成功率和完全流产率(Z=1.87,P=0.06,95%CI 0.98~2.03;Z=10.25,P<0.00001,95%CI 3.15~5.43),降低胎盘胎膜残留率(Z=9.25,P<0.00001,95%CI 0.14~0.27)和不完全流产率(Z=4.21,P<0.00001,95%CI:0.42~0.73),恶心(呕吐)胃肠道反应较对照组发生率高(Z=11.87,P<0.00001,95%CI 11.62~30.65).结论:米非司酮联合米索前列醇阴道用药是终止中期妊娠安全有效的方法,但由于本系统评价纳入的文献数目及质量的局限性,尚需更为严谨的证据.
