开胸术后病人雾化吸入开始时间对雾化效果影响的研究

目的]探讨胸外科开胸术后病人雾化吸入开始时间对雾化吸入效果的影响,从而确定既有利于病人呼吸道功能恢复又舒适的最佳雾化开始时间.方法]采用方便抽样的方法抽取2009年3月-5月在北京某三级甲等医院胸外科病房住院并行开胸手术术后病人61例,随机分成3组,A组为全身麻醉清醒后、B组为全身麻醉清醒后4 h～6 h、C组为全身麻醉清醒后12 h～18 h给予第一次空气压缩式雾化吸入治疗,每日3次,每次15 min～20 min,饭前或饭后30 min进行,两次时间间隔4 h～6 h.连续雾化3 d.记录3组病人术日至术后3 d的咳嗽、咳痰、咳痰难易度、痰液性状及口咽舒适度情况.结果]3组病人术后1 d咳痰难易度、术后1 d痰液性状、术后2 d痰液性状、术日的口咽舒适度比较差异有统计学意义(P＜0.05).结论]全身麻醉清醒后及全身麻醉清醒后4 h～6 h开始雾化吸入治疗均能更早地稀释痰液,提高病人排痰效果,增加病人的舒适度,缩短术后拔管时间.全身麻醉清醒后4 h～6 h开始雾化吸入治疗的病人口咽无明显不适,平均拔管时间早于全身麻醉清醒组,因此推荐全身麻醉清醒后4h～6 h开始雾化吸入治疗为佳.

Study on influence of starting time of nebulization inhalation on nebulization effect of patients after accepting thoracotomy

Objective:To probe into the influence of starting time of nebulization inhalation on effect of nebulization in thoracic surgery patients after accepting thoracotomy,so as to determine the best nebulization start time which not only helped patients for respiratory tract recovery but also let them feel comfortable.Methods:To adopt convenient sampling method,a total of 61 inpatients accepted thoracotomy in thoracic surgery ward of third grade class A hospital of Beijing city from March to May 2009 were selecte...
