两种不同气道湿化方法用于脑梗死患者气管切开术后疗效比较

目的比较两种不同气道湿化方法用于脑梗死患者气管切开的疗效。方法60例脑梗死气管切开患者按数字表法随机分为观察组及对照组各30例，观察组采用以输液泵持续滴注0．45％氯化钠溶液气道湿化法，对照组采用以注射器间断滴入0．45％氯化钠注射液气道湿化法，比较两组患者刺激性咳嗽、痰痂形成、气道黏膜出血、肺部感染等发生情况。结果观察组刺激性咳嗽、痰痂形成、气道黏膜出血、肺部感染等发生率明显低于对照组，差异有统计学意义（均P〈0．05）。结论应用输液泵持续滴注0．45％氯化钠溶液气道湿化法能明显减少肺部感染及痰痂形成，预防刺激性咳嗽与气道黏膜出血，值得临床推广应用。

Comparison of effect of different method of airway humidification in cerebral infarction patients after tracheotomy

Objective To compare the result of different method of airway humidification in cerebral infarction patients after tracheotomy. Methods 60 cerebral infarction patients after tracheotomy were divided into experiment group and control group randomly. 0.45% normal sodium was dropt with infusion pump consistently to humidify airway in experiment group and liquid was dropt with injector every 30 ～ 60 minutes in control group. Cough, sputum crusts,mucosa bleeding and pulmonary infection were compared between two groups. Result Therapeutic effect of experiment group was significantly better than control group (P ＜ 0.05). Conclusion 0. 45% normal sodium been dropted with infusion pump consistently to humidify airway could reduce the incidence of sputum crusts and pulmonary infection, prevent cough and mucosa bleeding obviously.
