雾化吸入麻醉药物时不同给氧方式应用于支气管镜检查术的效果观察

Clinical effect of different oxygen supply methods during anesthetics inhalation for bronchoscopy examination

目的：探讨压缩雾化吸入麻醉药物时不同的给氧方式应用于支气管镜检查术的临床效果。方法将接受支气管镜检查术的216例患者随机分为观察组和对照组，每组各108例。观察组在进行压缩雾化吸入麻醉药物时给予鼻导管低流量（3 L／min）吸氧；对照组在支气管镜检查前压缩雾化吸入麻醉药物同时在口含器上加入氧气低流量（3 L／min）经口吸入。动态观察两组在压缩雾化吸入前后的血氧饱和度、脉搏以及患者舒适度、麻醉效果。结果雾化吸入后5，10，20，25，30 min观察组患者血氧饱和度分别为（93±1）％，（95±1）％，（94±2）％，（94±1）％，（95±1）％，均高于对照组，差异有统计学意义（t值分别为10．482，12．747，13．044，13．301，13．763；P＜0．05）。雾化吸入后5，10，20，25，30 min观察组患者脉搏分别为（90±1），（91±2），（91±2），（92±1），（91±2）次／min，均低于对照组，差异有统计学意义（t值分别为7．867，9．151，10．207，11．701，11．063；P＜0．05）。结论压缩雾化吸入时在口含器上加入氧气经口吸入能稳定患者的血氧饱和度及脉搏，提高患者的舒适度和压缩雾化吸入的麻醉效果。

Objective To compare the clinical efficacy of different oxygen supply methods during anesthetics inhalation for bronchoscopy examination.Methods Totals of 216 patients who received bronchoscopy examination were randomly divided into two groups, with 108 cases in each.Low flow oxygen inhalation （3 L/min） with nasal canula was performed in the observation group, low flow oxygen inhalation （3 L/min） through mouth device was carried out in control group during the process of anesthetics inhalation.SpO2 , pulse, comfort degree and satisfaction with anesthesia were recorded and compared between the two groups.Results At the time of 5, 10, 20, 25, 30 minutes after anesthetics inhalation, SpO2 of the observation group were （93 ±1）%, （95 ±1）%, （94 ±2）%, （94 ±1）% and （95 ±1）%, which were significantly higher than those in the control group （t=10.482, 12.747, 13.044, 13.301, 13.763, respectively;P〈0.05）.At the time of 5, 10, 20, 25, 30 minutes after anesthetics inhalation, the pulse of the observation group were （90 ±1）, （91 ±2）, （91 ±2）, （92 ±1） and （91 ±2）, which were significantly lower than those in the control group （t=7.867, 9.151, 10.207, 11.701, 11.063, respectively;P〈0.05）.Conclusions Oxygen inhalation through mouth device during anesthetics inhalation can maintain SpO2 and pulse of patients, increase the comfort degree and satisfaction with anesthesia, relief the pain of patient, and make the bronchoscopy examination more smoothly, so it should be recommended in clinical practice.
