摘要
目的探讨旋转振动排痰仪对下呼吸道感染患者的排痰效果。方法按随机对照临床实验原则将60例患者分为4组,分别给予自动方式和手动方式的3个不同频率段协助排痰,观察1w后痰量、血氧饱和度变化情况以及体温、血常规恢复正常范围的天数。结果在手动方式3组中,670～1280Hz段速组排痰效果好于其他2组,并且患者的不良反应少。而自动方式的排痰效果均优于手动方式各组。结论采用适宜体位,选用自动或中频段速的手动方式应用排痰仪,能够取得理想的排痰效果。
Objective To investigate the tracheobronchial clearance of vibratory spum-ejection apparatus in the aged with lower respiratory tract infection. Methods 60 patients were randomly divided into four groups, one with auto-mode and the other three with manual-mode of three different frequencies to assist tracheobronchial clearance. After a week, the changes of sputum, blood oxygen saturation and the days that the temperature and the time of hemogram returning to normal were observed. Results Auto-mode was superior to manual-mode in tracheobronchial clearance among the three groups. Among the manual-mode groups, the group with frequency of 670~1280Hz had better efficacy than the other two groups, and adverse effect was less. Conclusions Using suitable posture, auto-mode or manual-mode with medial frequency could achieve ideal tracheobronchial clearance if using vibratory sputum-ejection apparatus.
