ObjectiveTo systematically evaluate the effect of combination of motherwort injection and oxytocin for promoting the involution of uterus. MethodsData of randomized controlled trials (RCTs) of motherwort injection and oxytocin in promoting the effect of postpartum involution of uterus were collected by searching the electronic databases including PubMed, EMbase, CNKI, WanFang Data, CENTRAL and WHO ICTRP from inception to August 26th, 2016. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data, and assessed the risk of bias of included studies. Meta-analysis was conducted by RevMan 5.3 software. ResultsA total of 18 RCTs involving 6 468 patients were included. The results of meta-analysis showed that:Compared with the oxytocin alone group, the combination group of motherwort injection and oxytocin was higher on promoting the drop height of uterus (MD=1.33, 95%CI 1.03 to 1.63), lower on the height of uterus (MD=-2.12, 95%CI -2.64 to -1.61) and duration of lochia (MD=-7.11, 95%CI -8.84 to -5.38). There was no statistical difference in adverse effect rate between the two groups (OR=0.87, 95%CI 0.64 to 1.19, P=0.38). ConclusionsMotherwort injection combined with oxytocin is superior to oxytocin alone in promoting the drop height of postpartum uterus and shortening the duration of lochia. Because of the low quality of the included studies, more high quality RCTs are needed to prove the above conclusion.
Objectives To systematically review the efficacy and safety of carbetocinversusoxytocin on the prevention of postpartum hemorrhage (PPH) for women undergoing vaginal delivery. Methods PubMed, The Cochrane Library, Web of Science, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on carbetocinversusoxytocin on the prevention of PPH for women undergoing vaginal delivery from inception to January 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 and Stata 12.0 software. Results A total of 16 RCTs including 2 537 patients were included. The results of meta-analysis showed that: compared to oxytocin, carbetocin could reduce the amount of blood loss within 24h (MD=–107.68, 95%CI–130.21 to –85.15, P<0.000 01) and 2h (MD=–85.98, 95%CI–93.37 to –78.59,P<0.000 01), hemoglobin (Hb) within 24h after delivery (MD=–5.63, 95%CI–6.82 to –4.43,P<0.000 01), the occurrence of PPH (RR=0.46, 95%CI 0.32 to 0.66,P<0.000 01) and the requirement for additional uterotonic agents (RR=0.63, 95%CI 0.48 to 0.84,P=0.002). There was no significant difference in the risk of adverse effects between two groups. Conclusions Current evidence shows that carbetocin is superior to oxytocin in the prevention of PPH for women undergoing vaginal delivery, without increasing the adverse effects. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above the conclusion.
