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.
