摘要

目的:传统上,术前建议禁食6-8小时,以防止呼吸系统并发症。然而,最近的证据表明,在全身麻醉前2小时摄入透明液体可能是安全的。本研究旨在评价全麻手术患者减少禁食时间并摄入清液的安全性和有效性。方法:将60例全麻下择期行内镜下全腹膜外成形术的成年患者随机分为两组,每组30例。对照组禁食过夜(每次口服不禁食),而液体组允许清除液体直到手术前2小时。插管后测定胃内容物体积和pH值。使用视觉模拟量表评估术前和术后的口渴和饥饿水平。术后声音嘶哑、恶心、呕吐、血氧饱和度在恢复室监测。结果:液体组平均摄入液体520 mL。两组均未见严重的呼吸系统并发症。液体组术前和术后的口渴和饥饿评分均显著降低(P < 0.001)。胃内容物体积和酸度在组间无显著差异,大多数患者的体积可以忽略不计(结论:全麻前2小时允许摄入透明液体是安全的,不会增加呼吸系统并发症的风险。它有效地减少了口渴和饥饿,在不影响安全性的情况下提高了患者的舒适度。

The safety and effect of preoperative reduced fasting time by oral clear liquid administration in adult surgery patients: a randomized controlled trial.

Purpose: Traditionally, 6-8 hours of fasting has been recommended before surgery to prevent respiratory complications. However, recent evidence suggests that intake of clear fluids up to 2 hours before general anesthesia may be safe. This study aimed to evaluate the safety and efficacy of reduced fasting time with clear liquid intake in surgical patients under general anesthesia.

Methods: In this randomized controlled trial, 60 adult patients undergoing elective endoscopic total extraperitoneal plasty under general anesthesia were divided into two groups (n = 30 each). The control group fasted overnight (nothing per oral), while the liquid group was allowed clear fluids until 2 hours before surgery. Gastric content volume and pH were measured after intubation. Thirst and hunger levels were assessed pre- and postoperatively using a visual analogue scale. Postoperative hoarseness, nausea, vomiting, and oxygen saturation were monitored in the recovery room.

Results: The liquid group consumed an average of 520 mL of fluid. No serious respiratory complications were observed in either group. Pre- and postoperative thirst and hunger scores were significantly lower in the liquid group (P < 0.001). Gastric content volume and acidity showed no significant differences between groups, with most patients having negligible volumes (<1 mL).

Conclusion: Permitting clear liquid intake up to 2 hours before general anesthesia is safe and does not increase the risk of respiratory complications. It effectively reduces thirst and hunger, improving patient comfort without compromising safety.
