目的：探讨PDCA循环管理模式对ICU 气管插管患者发生非计划性拔管的预防价值。方法将180例ICU气管插管患者采用随机数字表法分为两组，各90例。观察组采用 PDCA循环管理模式，对照组采用常规管理，比较两组患者的非计划拔管发生率、住院时间及住院费用差异。结果观察组患者非计划拔管发生率为4．4％，对照组为16．7％，观察组显著少于对照组（P＜0．01），观察组住院时间和住院费用显著少于对照组（P＜0．01）。结论 PDCA循环管理可以明显降低IC U气管插管患者的非计划拔管发生率、住院时间及住院费用，值得临床推广应用。“,”Objective To explore the preventive value of PDCA cycle management model to unplanned en‐dotracheal extubation (UEX) of ICU patients with trachea cannula .Methods A total of 180 ICU patients with trachea cannula were randomly assigned to two groups of 90 ones each .Observation group was man‐aged with PDCA cycle and control group with routine management method ,intergroup UEX rate ,average length of stay and hospitalization fee were compared .Results UEX incidence was 4 .4% in observation and 16 .7% in control group ,the former significantly lower than the latter (P<0 .01) ,and so were aver‐age length of stay and hospitalization fee (P<0 .01) .Conclusion PDCA cycle management model could obviously lower the UEX rate ,average length of stay and hospitalization fee of ICU patients with trachea cannula and deserves clinical generalization and application .
