吸氧面罩与麻醉机螺纹管间改良设计连接管在无痛胃镜检查中的应用观察

Application of improved connecting tube in oxygen mask and threaded pipe of anesthesia machine in painless gastroscopy

目的观察笔者改良设计连接管在无痛胃镜检查中的有效性。方法将120例无痛胃镜检查患者分为实验纽（A组，连接管加普通吸氧面罩组，n=60例）和对照组（B组，胃镜专用麻醉面罩纽，n=60例），观察两组检查中的临床效果。结果两组患者发生呼吸抑制率比较差异无统计学意义，两组患者拔出胃镜比较差异无统计学意义。结论改良后连接管只需和普通吸氧面罩一起使用即可完成胃镜操作，是无痛胃镜中安全有效的选择之一，值得在临床应用中进一步推广。

Objective To observe the availability of author-made connecting tube in painless endoscopy. Methods One hundred and twenty cases of painless endoscopy were divided into experimental group（ group A, connecting tube and ordinary oxygen mask group, n = 60 cases ） and control group （group B, endoscopy, anesthesia mask group, n = 60 cases）. The clinical effects were observed. Resuits The difference of incidence rate of respiratory depression between the two groups was not statistically significant. There was also no significant difference in unplug the endoscopy between the two groups. Conclusions It is a safe and effective choice for painless gastroscope by self connecting tube and ordinary oxygen mask to completing the gastroscopy, it＇ s worthy of further promotion in the clinical application.
