Abstract
To examine whether chewing gum hastens the return of gastrointestinal function after a cesarean delivery. All randomized controlled trials comparing the use of chewing gum in the immediate postoperative recovery period (i.e. intervention group) with a control group were included in the meta-analysis. The primary outcome was the time to first flatus in hours. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of mean difference (MD) or relative risk (RR) with 95% confidence interval (CI). Seventeen trials, including 3041 women, were analyzed. Trials were of moderate to low quality with different inclusion criteria. In most of the included trials chewing gum was given right after delivery, three times a day for 30 min each and until the first flatus. Women who were randomized to the chewing gum group had a significantly lower mean time to first flatus (MD - 6.49 h, 95%CI -8.65 to -4.33), to first bowel sounds (MD - 8.48 h, 95%CI -9.04 to -7.92), less duration of stay (MD - 0.39 days, 95%CI -0.78 to -0.18), lower time to first feces (MD - 9.57 h, 95% CI -10.28 to 8.87) and to the first feeling of hunger (MD - 2.89 h, 95%CI -4.93 to -0.85), less number ...Continue Reading
