目的：通过比较两种气道湿化方法对重型颅脑损伤气管切开患者气道的湿化效果，为临床上进一步选择合理有效的气道湿化方法提供依据。方法选取2014年6月~12月某三甲医：神经外科重症监护病房使用气管切开套管的连续病例，随机分为实验组(47例)和对照组(47例)，实验组采用微量泵持续点滴法，对照组采用间歇滴注法湿化气道，比较两组患者的湿化效果(痰液粘稠度、痰痂形成发生率)。结果实验组的湿化效果优于对照组(24 h <0.05；72 h <0.005)。结论对于重型颅脑损伤患者，气管切开后使用输液泵控制持续点滴湿化人工气道，稀释痰液、减少痰痂形成效果可靠，安全、方便，值得临床推广。“,”Objective By comparing the two methods of airway humidification severe craniocerebral disease tracheotomy airway humidification ef ect, and further select a reasonable and ef ective airway humidification methods provide the basis for clinical practice. Methods Selected in June 2014 to December a hospital neurosurgery ICU tracheostomy tube continuous use cases were randomly divided into experimental group (47 cases) and control group (47 cases), the experimental group continued to drip micro pump method, in the control group using a batch airway instil ation wet, compared between two groups of patients (sputum viscosity, sputum formation incidence). Results The ef ect of wet experimental group was bet er than the control group (24 hours <0.05;72 hours <0.005). Conclusion For patients with severe craniocerebral disease after tracheotomy using a continuous drip infusion pump to control the ef ect of reliable, safe, convenient, worthy of promotion wet artificial airway mucus, reduce the formation of sputum.
