目的:观察在呼吸机依赖患者中间歇性停机法的脱机成功率。方法:13例呼吸机依赖的患者随机分为两组,试验组6例,采用间歇性停机法,对照组7例,采用压力支持通气和同步间歇指令通气方法,比较两周内的脱机成功率。结果:两周内试验组和对照组的脱机成功率分别为83.3%和14.3%,差异有统计学意义(P<0.05)。结论:COPD呼吸依赖患者脱机时,采用间歇性停机法具有较高的脱机成功率。
OBJECTIVE: To observe the success rate of off-line in intermittent ventilator-dependent patients. Methods: Thirteen ventilator dependent patients were divided into two groups at random. Six patients in trial group were treated with intermittent shutdown method and control group with seven patients. Pressure assisted ventilation and synchronized intermittent mandatory ventilation were used to compare two weeks’ offline success rate. Results: The off-line success rates of the experimental group and the control group were 83.3% and 14.3% in two weeks respectively, with statistical significance (P <0.05). Conclusion: COPD patients with respiratory dependence offline, the use of intermittent shutdown method has a high success rate of off-line.
