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