Gum chewing has been reported to enhance the intestinal function recovery after caesarean section, current perspectives and practice guidelines vary widely on the use of gum chewing, more studies on the role of gum chewing after caesarean section are needed.
We performed a comprehensive, systematic meta-analysis of randomized controlled trials (RCTs) on the efficacy of gum chewing after caesarean section. Studies were identified by searching EMBASE et al database (until June 30, 2016). Summary odd ratios or weighted mean differences with 95% confidence intervals were calculated for each outcome with fixed- or random-effects model.
Ten RCTs with a total of 1659 women were included in our meta-analysis. Gum chewing provided significant benefits in reducing the time to first passage of flatus, first defecation, first bowel sound, first bowel movement and the length of hospital stay, but not in the time to first feeling of hunger.
Gun chewing hastens the intestinal function recovery after caesarean section and offers a safe and inexpensive option. High-quality and larger-scale RCTs are still warranted to clarify the role of gum chewing in intestinal function recovery after caesarean section.
据报道，剖宫产术后嚼口香糖可促进肠道功能恢复，但目前对于嚼口香糖的应用，观点和实践指南差异很大，仍需要更多关于剖宫产术后嚼口香糖作用的研究。
我们对剖宫产术后嚼口香糖疗效的随机对照试验进行了全面、系统的荟萃分析。通过检索EMBASE等数据库（截至2016年6月30日）来确定研究。采用固定效应或随机效应模型为每个结局计算汇总比值比或加权平均差及95%置信区间。
我们的荟萃分析纳入了10项随机对照试验，共1659名女性。嚼口香糖在缩短首次排气时间、首次排便时间、首次肠鸣音时间、首次排便次数和住院时间方面有显著益处，但在首次有饥饿感的时间方面没有作用。
嚼口香糖可加速剖宫产术后肠道功能恢复，是一种安全且廉价的选择。仍需要高质量、大规模的随机对照试验来阐明嚼口香糖在剖宫产术后肠道功能恢复中的作用。
