The goal of this study was to evaluate the effects of xylitol gum chewing on gastrointestinal recovery after cesarean section.
Women who underwent cesarean section (N = 120) were randomly allocated into Group A (xylitol gum), Group B (nonxylitol gum), or the control group (no chewing gum). Every 2 hr post-cesarean section and until first flatus, Groups A and B received two pellets of chewing gum and were asked to chew for 15 min. The times to first bowel sounds, first flatus, and first defecation were then compared among the three groups.
Group A had the shortest mean time to first bowel sounds (6.9 ± 1.7 hr), followed by Group B (8 ± 1.6 hr) and the control group (12.8 ± 2.5 hr; one-way analysis of variance, p < .001; Scheffe's post hoc comparisons, p < .05). The gum-chewing groups demonstrated a faster return of flatus than the control group did (p < .001), but the time to flatus did not differ significantly between the gum-chewing groups. Additionally, the differences in the time to first defecation were not significant.
After cesarean section, chewing gum increased participants' return of bowel activity, as measured by the appearance of bowel sounds and the passage of flatus. In this context, xylitol-containing gum may be superior to xylitol-free gum.
本研究旨在评估剖宫产术后咀嚼木糖醇口香糖对胃肠道恢复的影响。
将接受剖宫产手术的女性（N = 120）随机分为A组（木糖醇口香糖组）、B组（非木糖醇口香糖组）或对照组（不咀嚼口香糖）。剖宫产术后每2小时直至首次排气，A组和B组各接受两粒口香糖，并被要求咀嚼15分钟。然后比较三组首次肠鸣音、首次排气和首次排便的时间。
A组首次肠鸣音的平均时间最短（6.9±1.7小时），其次是B组（8±1.6小时）和对照组（12.8±2.5小时；单因素方差分析，p <.001；谢费尔事后比较，p <.05）。咀嚼口香糖组的排气恢复速度比对照组快（p <.001），但咀嚼口香糖组之间的排气时间差异不显著。此外，首次排便时间的差异也不显著。
剖宫产术后，通过肠鸣音的出现和排气情况衡量，咀嚼口香糖可加快参与者肠道活动的恢复。在此情况下，含木糖醇的口香糖可能优于不含木糖醇的口香糖。
