气管切开后两种雾化吸入方式的效果观察

目的探讨气管切开后一种较为理想的雾化吸入方式,提高湿化效果。方法将40例气管切开患者分为对照组和观察组各20例。对照组采用气道间断滴药加常规氧气雾化吸入法,观察组采用气道间断滴药加改良氧气雾化吸入法,比较两组湿化效果。结果观察组气道出血、痰痂形成、肺部感染发生率低于对照组,但两组比较,差异无统计学意义(均P>0.05);两组每日吸痰次数比较,差异有统计学意义(P<0.01)。两组痰液成分测定值比较,差异有统计学意义(P<0.05)。结论改良气管切开氧气雾化法能将雾化药液充分吸入气道,可降低痰液的粘稠度,提高气道湿化效果。

Comparison of two methods of nebulization for tracheotomy

Objective To explore an optimal method of nebulization for patients with tracheotomy,and to improve the effects of humidification.Methods Forty patients with tracheotomy were divided into two groups of 20.The control group received intermittent drips of medications into airway plus conventional oxygen-driven nebulization,while the observation group were subjected to intermittent drips of medications into airway plus modified oxygen-driven nebulization.Humidification effects were compared between the two groups.Results The occurrence rates of airway hemorrhage,phlegm(sputum) production and pulmonary infection in the observation group were lower than those in the control group,but there were no significant differences between the two groups.Statistically significant differences were found between the two groups in the number of times of endotracheal suctioning and in levels of sputum components(P<0.01,P<0.05).Conclusion Use of modified oxygen-driven nebulization for tracheotomy can boost absorption of nebulized medications,which could reduce sputum viscosity and improve humidification effect.
