0.45％盐水气道湿化在颅脑损伤气管切开患者中的应用效果

摘要

目的 探讨0.45％盐水气道湿化在颅脑损伤切开患者中的应用效果.方法 将58例颅脑损伤气管切开的患者为研究对象,设为观察组,采用0.45％盐水进行气道湿化.选取同期收治的40例颅脑损伤气管切开的患者为对照组,采用灭菌生理盐水进行气道湿化.比较2组的气道湿化效果、痰痂形成率、不良反应的发生率.结果 观察组气管切开3d、5d的痰液pH值小于对照组(P＜0.05);2组患者的气道湿化疗效及痰痂形成率均无统计学意义(P＞0.05);观察组的肺部感染、刺激性咳嗽、呼吸道黏膜出血的发生率低于对照组(P＜0.05).结论 采用0.45％盐水进行气道湿化符合患者的生理需求,湿化效果好,且不良事件发生率低,值得推广.%Objective To investigate the effect of 0.45 ％ saline for airway humidification in patients with craniocerebral injury after tracheotomy.Methods A total of 58 patients with craniocerebral injury after tracheotomy treated in our department were as observation group,given 0.45％ saline for airway humidification.And 40 craniocerebral injury patients after tracheotomy at the same time were as control group,given sterilized saline for airway humidification.The effect of airway humidification,the rate of sputum scab formation,and the incidence of adverse reactions were compared between the two groups.Results The pH of sputum after 3,5 d of tracheotomy in the observation group was lower (P ＜ 0.05),but the effect of airway humidification and the rate of sputum scab formation in the two groups showed no statistically significant difference (P ＞ 0.05).The incidence of pulmonary infection,irritating cough and respiratory mucosal bleeding in the observation group were lower than that in the control group (P ＜ 0.05).Conclusion The 0.45％ saline solution for airway humidification is in accordance with the physiological needs of the patients,and has better wetting effect and lower incidence of adverse events.
