不同呼吸机撤机策略的临床疗效评估

目的:比较计划性撤机、经验性撤机和智能软件为主导的撤机模式的优劣。方法:60例机械通气患者随机分成3组:经验性撤机(T组)20例、计划性撤机(SBT组)20例和以智能软件为主导的撤机方式(K组)20例,进行撤机试验。结果:SBT组、K组患者机械通气时间、住院时间、住院费用、气管切开率和呼吸机相关性肺炎发生率均低于T组,撤机成功率高于T组,差异有统计学意义(P<0.05,P<0.01)。SBT组与K组间差异无统计学意义(P>0.05)。结论:计划性撤机和智能软件为主导的撤机模式均能够缩短机械通气时间和住院时间,降低撤机后并发症和死亡率,减轻患者经济负担。

Clinical curative effect evaluation of three different ventilator weaning strategies

Objective:To compare the effects of planned,experienced and software dominated ventilator weaning modes.Meth-ods:A total of 60 patients with mechanical ventilation treatment were randomly divided into T group (n =20),SBT group (n =20) and K group (n =20),with experienced,planned,and software dominated ventilator weaning modes,respectively.Results:SBT group and K group received shorter duration of mechanical ventilation and length of stay,lower cost hospitalization,lower incidence of trache-otomy and ventilator associated pneumonia (VPA)compared with T group (P <0.05,P <0.01 ).The rate of weaning successfully in SBT group and K group was higher than that in T group(P <0.05,P <0.01 ),but with no significant difference between SBT group and K group (P >0.05).Conclusion:Planned and software dominated ventilator weaning modes is effective to reduce the duration of mechanical ventilation ,length of stay and incidence of complication in patients with mechanical ventilation treatment.
