Aim: To compare the efficacy of three postoperative feeding regimens on bowel function recovery after term elective cesarean section (CS). Methods: Women recruited for this randomized trial were allocated into three groups. Women in group (A) were instructed to chew sugarless gum for 10 min every 2 h after surgery. Group (B) mothers received IV fluids for 6 h followed by sipping fruit juices sweetened with honey. Group (C) had oral intake of clear fluids after passage of flatus and regular diet with the passage of bowel movement. The main outcome measures were the timing of first return to bowel movement and initiation of regular diet. Results: The mean times to first hearing of bowel sounds, to first flatus passage and to first defecation were significantly lower in group A (10, 17.5 and 28.1 h, respectively) compared to groups B and C [15.1, 24.9 and 36 h (B) and 21.6, 38.8 and 49.4 h (C)]. Initiation of regular diet was significantly earlier in group A compared to groups B and C (21 vs. 27.5 and 40.3 h, respectively). Conclusion: Chewing gum appears to be more advantageous than early or traditional feeding regimens after term elective CS resulting in rapid recovery of bowel function.

三种不同方案对选择性剖宫产术后肠功能恢复的疗效：一项随机试验

目的：比较三种术后喂养方案对足月择期剖宫产（CS）后肠功能恢复的疗效。方法：为这项随机试验招募的女性被分为三组。(A) 组的女性被要求在手术后每 2 小时咀嚼一次无糖口香糖 10 分钟。(B) 组母亲接受静脉输液 6 小时，然后喝加蜂蜜的果汁。(C)组在排出肠胃气后口服清流质，随排便规律饮食。主要结局指标是首次恢复排便的时间和开始规律饮食的时间。结果：与 B 组和 C 组相比，A 组第一次听到肠鸣音、第一次排气和第一次排便的平均时间（分别为 10、17.5 和 28.1 小时）显着降低 [15.1, 24. 9 和 36 小时 (B) 和 21.6、38.8 和 49.4 小时 (C)]。与 B 组和 C 组相比，A 组开始规律饮食的时间明显更早（分别为 21 与 27.5 和 40.3 小时）。结论：在选择性 CS 后，口香糖似乎比早期或传统喂养方案更有利，导致肠道功能快速恢复。
