目的探讨无痛胃镜在消化内科的临床疗效。方法对163例胃肠疾病患者的临床资料进行回顾性分析。其中以79例接受常规胃镜检查的患者作为对照组,84例接受无痛胃镜检查的患者作为研究组。比较两组患者的平均操作时间以及不良反应发生情况。结果研究组平均操作时间(4.88±1.09)min明显低于对照组(7.45±1.33)min,差异具有统计学意义(P<0.05)。研究组总不良反应发生率8.33%明显低于对照组16.46%,差异具有统计学意义(P<0.05)。结论采用麻醉方法来进行的无痛胃镜技术,可明显减少操作时间,降低不良反应发生率,值得临床推广应用。 Objective To investigate the clinical effect of painless gastroscope in gastroenterology. Methods The clinical data of 163 patients with gastrointestinal diseases were analyzed retrospectively. Among them, 79 patients who underwent routine gastroscopy were taken as the control group, and 84 patients who underwent painless gastroscopy were selected as the study group. Compare the average operation time of two groups of patients and the occurrence of adverse reactions. Results The average operation time (4.88 ± 1.09) min in study group was significantly lower than that in control group (7.45 ± 1.33) min, the difference was statistically significant (P <0.05). The incidence of adverse reactions in the study group was significantly lower than that in the control group (8.33% vs 16.46%, P <0.05). Conclusions The painless gastroscopy using anesthesia can significantly reduce the operating time and reduce the incidence of adverse reactions, which is worthy of clinical application.
