摘要
背景:当代术前喂养指南允许在麻醉前 6 小时内喂固体食物,2 小时内喂清水。在剖腹产手术中,缺乏支持这种方法的临床试验证据。许多医疗从业人员继续奉行从午夜到手术前不进食的保守政策,尤其是对孕妇而言:研究设计:一项随机对照试验于2020年10月至2022年5月在马来亚大学医疗中心产科进行。504名计划剖宫产的参与者被随机分配:252人在术前自由饮水,直到接到通知派往手术室或从午夜开始禁食。主要结果是围手术期呕吐和产妇满意度。根据情况使用 t 检验、曼-惠特尼 U 检验和 Chi-Square 检验进行分析:结果:剖宫产术后 6 小时内的呕吐率为 9/252 (3.6%) vs. 24/252 (9.5%) RR 0.38 95% CI 0.18-0.79 p=0.007,产妇满意度评分(0-10 VNRS)中位数[四分位间范围]9 [8-10] vs. 5 [3-7] p结论:与禁食相比,免费提供的水对产妇更有效:与禁食相比,计划剖宫产术中自由饮水可减少围术期呕吐,深受产妇欢迎。术前和术中的一些次要结果也得到了改善。然而,剖宫产后恢复和新生儿预后并无不同。
Preoperative free access to water compared to fasting for planned cesarean under spinal anesthesia: a randomized controlled trial.
Background: Contemporary guidance for preoperative feeding allows solids up to 6 hours and clear fluids up to 2 hours before anesthesia. Clinical trial evidence to support this approach for cesarean delivery is lacking. Many medical practitioners continue to follow conservative policies of no intake from midnight to the time of surgery, especially in pregnant women.
Objective: This study aimed to evaluate the pragmatic approach of permitting free access to water up to the call to dispatch to the operating theater vs fasting from midnight in preoperative oral intake restriction for planned cesarean delivery under spinal anesthesia on perioperative vomiting and maternal satisfaction.
Study design: A randomized controlled trial was conducted in the obstetrical unit of the University of Malaya Medical Centre from October 2020 to May 2022. A total of 504 participants scheduled for planned cesarean delivery were randomized: 252 undergoing preoperative free access to water up to the call to dispatch to the operating theater (intervention group) and 252 undergoing fasting from midnight (fasting arm). The primary outcomes were perioperative vomiting and maternal satisfaction. Analyses were performed using t test, Mann-Whitney U test, and chi-square test, as appropriate.
Results: Of note, 9 of 252 patients (3.6%) in the intervention group and 24 of 252 patients (9.5%) in the control group had vomiting at up to 6 hours after completion of cesarean delivery (relative risk, 0.38; 95% confidence interval, 0.18-0.79; P=.007), and the maternal satisfaction scores (0-10 visual numerical rating scale) were 9 (interquartile range, 8-10) in the intervention group and 5 (interquartile range, 3-7) in the control group (P<.001). Assessed before dispatch to the operating theater, feeling of thirst was reported by 69 of 252 patients (27.4%) in the intervention group and 134 of 252 patients (53.2%) in the control group (relative risk, 0.52; 95% confidence interval, 0.41-0.65; P<.001), capillary glucose levels were 4.8±0.7 mmol/L in the intervention group and 4.9±0.8 mmol/L in the control group (P=.048), and preoperative intravenous fluid hydration was commenced in 49 of 252 patients (19.4%) in the intervention group and 76 of 252 patients (30.2%) in the control group (relative risk, 0.65; 95% confidence interval, 0.47-0.88; P=.005). In the operating theater, ketone was detected in the catheterized urine in 38 of 252 patients (15.1%) in the intervention group and 78 of 252 patients (31.0%) in the control group (relative risk, 0.49; 95% confidence interval, 0.25-0.59; P<.001), and the numbers of doses of vasopressors needed to correct hypotension were 2.3±1.7 in the intervention group and 2.7±2.2 in the control (P=.009). The recommendation rates for preoperative oral intake regimen to a friend were 95.2% (240/252) in the intervention group and 39.7% (100/252) in the control group (relative risk, 2.40; 95% confidence interval, 2.06-2.80; P<.001), in favor of free access to water. Other assessed maternal and neonatal outcomes were not different.
Conclusion: Compared with fasting, free access to water in planned cesarean delivery reduced perioperative vomiting and was strongly favored by women. In addition, several pre- and intraoperative secondary outcomes were improved. However, postcesarean delivery recovery and neonatal outcomes were not different.
