Different regimens of penicillin antibiotics given to women routinely for preventing infection after cesarean section: A systematic review and meta analysis.

ABSTRACT

BACKGROUND: Varied regimens of penicillin antibiotics were given to women for preventing infection after cesarean section, but there is no study compares the effectiveness and safety of them. METHODS: We searched MEDLINE, Embase, CENTRAL, CNKI, Wanfang, VIP, and CBM Database, and contacted experts in the field and searched reference lists of retrieved studies. We included randomized controlled trials comparing different regimens of penicillin antibiotics given to women after cesarean section. Two review authors independently assessed the studies for inclusion, assessed risk of bias, and carried out data extraction. RESULTS: A total of 18 randomized controlled trails (involving 3287 pregnant women) were eligible. Compared with after umbilical cord clamping, penicillin antibiotics prophylaxis before skin incision could reduce the risk of endometritis for women undergoing cesarean. Compared with using penicillin antibiotics alone, using antibiotic-inhibitor combination could reduce the risk of endometritis or fever. No statistically significant difference was present between single-dose versus multidose, short term versus long term, intravenous injection versus lavag in the risk of reported outcomes. CONCLUSION: There is insufficient evidence to draw certain conclusions on which regimen of penicillin antibiotics is the best in this review. Further studies should pay attention to the study design, and besides the outcomes of pregnant women, researchers should focus on the outcomes of newborns.
