不同呼吸机湿化管道系统在老年机械通气患者中的应用效果对比

摘要

Objective:To explore the application efficacy of different ventilator tube-humidifying system in elderly patients with mechanical ventilation.Methods:A total of 140 elderly patients with mechanical ventilation were selected randomly divided into 3 groups,in which group A(n =43)was treated with MR410 tube-humidifying system,group B(n =47)with MR 730 tube-humidifying system and group C (n =50)with MR 850 tube-humidifying system with one-time double heating and autonomous water adding and hu-midification function.The humidifying efficacy,complications,ventilation duration and tube-nursing conditions were observed in all groups.Results:Group C was moderate in humidifying efficacy with highest ratio,followed by group B,and group A was the lowest, with all differences significant among 3 groups (P <0.01 ).Group C had no complications like sputum scab in pipes and airway spasm,but group A had the highest rate of complications,and there were significant differences among 3 groups (P <0.01 ).Group C was prominently lower in ventilation duration,total changing times of pipes,and the hours of nursing ventilator pipes than groups A and B,and the differences were significant (P <0.01 ).Conclusion:Application of MR 850 tube-humidifying system with one-time double heating and autonomous water adding and humidification function is excellent in humidifying efficacy,which can reduce the rate of complications and shorten the ventilation duration and nursing workloads.%目的：探讨不同呼吸机湿化管道系统在老年机械通气患者中的应用效果。方法：选取老年机械通气患者140例，随机分为3组，其中 A 组（n ＝43）使用 MR410型湿化管道系统，B 组（n ＝47）使用 MR730型湿化管道系统，C 组（n ＝50）采用 MR 850型一次性双加热式、自动加水加湿湿化管道系统。观察3组湿化效果、并发症发生情况、通气时间及管道护理情况。结果：C 组湿化效果适中比例最高，其次为 B 组，A 组最低，3组间差异有统计学意义（P ＜0．01）。C 组无导管痰痂和气道痉挛的发生，A 组发生率最高，3组间差异有统计学意义（P ＜0．01）。C 组通气时间、管道总更换次数、呼吸机管道护理时数均低于 A、B 组，差异有统计学意义（P ＜0．01）。结论：使用 MR850型一次性双加热式、自动加水加湿湿化管道系统湿化效果最好，能降低并发症发生率，缩短通气时间和护理工作量。
