摘　　要：目的探讨新型旁流呼气末二氧化碳(EtCO_(2))鼻咽通气道在保留自主呼吸全凭静脉麻醉的宫腔镜手术中的应用效果。方法选择2024年2—7月在高州市人民医院接受宫腔镜手术的160例患者,应用随机数表法将患者分为对照组与观察组,每组各80例。对照组采用传统鼻咽通气道,观察组接受新型旁流EtCO_(2)鼻咽通气道,均采用全凭静脉麻醉诱导与维持,术中保留自主呼吸,比较两组麻醉前(T0)、宫腔镜手术开始时(T1)、宫腔镜手术结束时(T2)、宫腔镜手术结束后10 min(T3)各时间的平均动脉压(MAP)、心率(HR)、血氧饱和度(SpO_(2)),并记录术中呼吸抑制、低氧血症和体动的发生情况以及术后不良反应。结果两组各时间点MAP和HR比较,差异无统计学意义(P>0.05);两组SpO_(2)在T0、T1、T3比较,差异无统计学意义(P>0.05)。T2观察组的SpO_(2)高于对照组(P<0.05)。观察组术中低氧血症发生率低于对照组(P<0.05)。两组体动、呼吸抑制(术中、术后)、恶心呕吐、鼻咽痛发生率比较,差异无统计学意义(P>0.05)。结论新型旁流EtCO_(2)鼻咽通气道能实时监测EtCO_(2),提供即时通气状态信息,辅助临床呼吸干预,改善术中氧合,减少低氧血症风险,提升宫腔镜手术麻醉的安全性。Objective To investigate the application effect of a novel sidestream end-tidal carbon dioxide(EtCO_(2))nasopharyngeal airway in hysteroscopic surgery with preservation of spontaneous breathing under total intravenous anesthesia.Methods A total of 160 patients who underwent hysteroscopic surgery in Gaozhou People’s Hospital from February to July 2024 were selected.They were divided into the control group and the observation group(80 patients each)using the randomized numerical table method.The control group was treated with the traditional nasopharyngeal airway,and the observation group was treated with the novel sidestream EtCO_(2) nasopharyngeal airway,both of which were induced and maintained by total intravenous anesthesia,with preservation of spontaneous breathing during the surgery.The mean arterial pressure(MAP),heart rate(HR),and blood oxygen saturation(SpO_(2))at each time point of before anesthesia(T0),at the beginning of the hysteroscopic surgery(T1),at the end of the hysteroscopic surgery(T2),and at 10 min after the end of the hysteroscopic surgery(T3)were compared between the two groups.The occurrence of intraoperative respiratory depression,hypoxemia and body movements and postoperative adverse reactions were recorded.Results The differences in MAP and HR at each time point between the control group and the observation group were not statistically significant(P>0.05).There was no statistically significant difference in SpO_(2) between the two groups at T0,T1,and T3(P>0.05).The SpO_(2) at T2 was higher in the observation group than that in the control group(P<0.05).The incidence of intraoperative hypoxemia was lower in the observation group than that in the control group(P<0.05).The comparison of incidences of body movements,respiratory depression(intraoperative and postoperative),nausea and vomiting,and nasopharyngeal pain showed no statistically significant difference between the two groups(P>0.05).Conclusion The novel sidestream EtCO_(2) nasopharyngeal airway can monitor EtCO_(2) in real time,pr
