呼末二氧化碳监测在ERCP麻醉中预防麻醉期间低氧血症应用效果

Effect of End-expiratory Carbon Dioxide Monitoring on the Prevention of Hypoxemia during Anesthesia in ERCP Anesthesia

目的:探讨呼末二氧化碳监测在内镜下经胰胆管造影(ERCP)麻醉中预防麻醉期间低氧血症应用效果。方法:选择2022年1月-2023年6月本院-行ERCP治疗的300例患者,用随机数表法分为试验组(n=150)和对照组(n=150)。对照组给予行常规心电图、血压和血氧饱和度监测,试验组在对照组基础上行呼末二氧化碳监测。比较两组一般资料、低氧血症、呼吸暂停、面罩加压给氧及改变头部姿势发生情况。结果:两组一般资料进行比较,无统计学差异(P>0.05);试验组低氧血症、呼吸暂停、面罩加压给氧均显著低于对照组,改变头部姿势发生率显著高于对照组,两组比较有统计学意义(P<0.05)。结论:ERCP麻醉患者中使用呼末二氧化碳监测可实时指导对患者进行辅助呼吸处理,降低ERCP麻醉期间低氧血症的发生率和面罩加压给氧率。

Objective:To study the effect of end-expiratory carbon dioxide monitoring on the prevention of hypoxemia during anesthesia in endoscopic retrograde cholangiopancreatography(ERCP)anesthesia.Methods:300 patients treated with ERCP in our hospital from January 2022 to June 2023 were selected and divided into experimental group(n=150)and control group(n=150)by random number table method.The control group received routine electrocardiogram,blood pressure and blood oxygen saturation monitoring,and the experimental group was monitored on the basis of the control group.General data,hypoxemia,apnea,mask pressure oxygen and head postural changes were compared between the two groups.Results:There was no significant difference in the general data between the two groups(P>0.05).Hypoxemia,apnea and mask pressure oxygen administration in experimental groups were significantly lower than those in control group,and the incidence of head posture change was significantly higher than that in control group,and the comparison between the two groups was statistically significant(P<0.05).Conclusion:The use of end-expiratory carbon dioxide monitoring in patients under ERCP anesthesia can guide the assisted respiratory management of patients in real time,and reduce the incidence of hypoxemia and mask pressure oxygen delivery rate during ERCP anesthesia.
