无痛胃镜检查禁饮时间缩短至2 h的可行性分析

Feasibility analysis of shortening the no drinking time before gastroscopy to 2 h

摘要:

目的 探讨将无痛胃镜检查禁饮时间缩短至2 h的可行性。方法 将240名志愿者随机分为非禁饮组（检查前2 h饮水不超过1 000 mL）和禁饮组（禁饮时间大于8 h），非禁饮组腹部彩色多普勒超声检查证实胃排空后，行无痛胃镜检查，禁饮组直接行无痛胃镜检查，比较两组患者检查完成率、误吸发生率、检查时间和视野清晰度。结果 两组患者均顺利完成检查，检查过程中无呕吐和误吸发生。非禁饮组检查前腹部彩色多普勒超声检查，证实所有患者胃内均已排空。非禁饮组和禁饮组检查时间为（204.7±31.2）和（201.4±25.9）s，视野清晰度B级以上分别为96.7%（116/120）和97.5%（117/120），差异均无统计学意义（P > 0.05）。结论 在饮水不超过1 000 mL的前提下，对于没有胃肠排空障碍的患者，禁饮2 h后行无痛胃镜检查，不会增加误吸发生率，不影响检查时的视野清晰度，且不降低检查效率，安全可行。

Abstract:

Objective To explore the feasibility of shortening the no drinking time before gastroscopy to 2 h.Method 240 volunteers were randomly divided into drinking group (drinking no more than 1 000 mL 2 h before the gastroscopy) and no-drinking group (don’t drink anything more than 8 h), the drinking group underwent abdominal color Doppler ultrasonography to confirm gastric emptying and then underwent painless gastroscopy, and the no-drinking group underwent painless gastroscopy directly. The gastroscopy completion rate, aspiration rate, examination time and visual field clarity were compared between the two groups.Results Both groups of patients successfully completed the examination, and no vomiting or aspiration occurred during the examination. The color Doppler ultrasonography of the abdomen before gastroscopy in the drinking group confirmed that the stomachs of all patients had been emptied. The average examination time of the two groups of patients was (204.7±31.2) and (201.4±25.9) s, and the visual field clarity above grade B was 96.7% (116/120) and 97.5% (117/120), respectively, and the difference was not statistically significant.Conclusion On the premise that the drinking water is less than 1 000 mL, for patients with no gastrointestinal emptying disorder, 2 h of no drinking will not increase the probability of aspiration, and will not affect the clarity of the visual field during the inspection, and it will not reduce the efficiency of gastroscopy. It is security and feasibility.
