预吸氧对丙泊酚麻醉在老年患者无痛胃镜检查中的安全性

Influence of preoxygenation on safety of propofol anesthesia in elderly patients receiving painless gastroscopy

目的探讨预吸氧对丙泊酚麻醉在老年患者无痛胃镜检查中的安全性与有效性。方法将我院收治的120例无痛胃镜检查的老年患者随机分为实验组和对照组,对照组的患者给予常规不吸氧,实验组的患者给予预吸氧。结果两组患者胃镜操作时间与苏醒时间无显著差异(P>0.05);呼吸抑制的发生率低于对照组(P<0.05),胃镜检查的过程中SpO2高于对照组及HR低于对照组(P<0.05),具有统计学意义。结论对采用丙泊酚麻醉行无痛胃镜检查老年患者给予预吸氧,可有效的对抗检查过程中出现的不同程度呼吸抑制所造成的缺氧,提高无痛胃镜检查的安全性。

Objective To investigate the influence of preoxygenation on the safety and effectiveness of propofol anesthesia in elderly patients receiving painless gastroscopy. Methods 120 elderly patients receiving painless gastroscopy in our hospital were randomly divided into the experimental group and the control group. The control group was given conventional non-oxygenation and the experimental group was given preoxygenation. Results The experimental group was not significantly different from the control group in the gastroscopic operation time and awakening time （P ~ 0.05）, was lower than the control group in the incidence of respiratory depression （P ~ 0.05）, was higher than the control group in the SpO2 and was slower than the control group in the HR （P 〈 0.05）, with statistical significance. Conclusion The application of preoxygenation in the elderly patients receiving propofol anesthesia in painless gastroscopy can effectively confront the anoxia caused by various degrees of respiratory depression in the examination process and increase the safety of painless ~astroscoDv examinatinn
