The use of chewing gum postoperatively has been shown to be useful in the recovery of postoperative ileus.
To evaluate the efficacy of using chewing gum as simulated feeding for the recovery of postoperative ileus after cesarean section.
Randomized, controlled, double-blind clinical trial in women ≥ 18 years, during the postoperative period of cesarean section, distributed in 2 groups, group A (chewing gum, n = 63) and group B (control, n = 63). The postoperative time elapsed until the first flatus, the presence of evacuation during the postoperative period before hospital discharge, and the time elapsed until the first postoperative evacuation and length of hospital stay (HS) were evaluated.
126 patients were included. Postoperative evacuation before hospital discharge was more frequent in group A (p = 0.01); in addition, there was a shorter length of HS (p = 0.04); no patient presented nausea during the postoperative period (p = 0.0001). No difference was observed between the study groups regarding the time to onset of first flatus (p = 0.17), or the time elapsed to first postoperative evacuation (p = 0.07). The number needed to treat (NNT) was 5 and the absolute risk reduction (ARR) was 21%, for both the presence of nausea and the absence of postoperative evacuation. No patient reported complications.
The use of chewing gum as simulated feeding after cesarean section is effective and safe for recovery from postoperative ileus.
术后咀嚼口香糖已被证明对术后肠梗阻的恢复有益。
评估咀嚼口香糖作为模拟进食对剖宫产术后肠梗阻恢复的疗效。
对年龄≥18岁的剖宫产术后女性进行随机、对照、双盲临床试验，分为两组，A组（咀嚼口香糖，n = 63）和B组（对照组，n = 63）。评估直至首次排气的术后时间、出院前术后期间的排便情况、直至首次术后排便的时间以及住院时间（HS）。
纳入126例患者。A组出院前术后排便更频繁（p = 0.01）；此外，住院时间更短（p = 0.04）；术后期间无患者出现恶心（p = 0.0001）。在首次排气时间（p = 0.17）或首次术后排便时间（p = 0.07）方面，研究组之间未观察到差异。对于恶心的发生和术后未排便情况，治疗所需人数（NNT）为5，绝对风险降低（ARR）为21%。无患者报告并发症。
剖宫产术后使用咀嚼口香糖作为模拟进食对术后肠梗阻的恢复有效且安全。
