目的 探讨人工气道风险防范管理引入失效模式和效果分析( FMEA)对共同风险系数( RPN)值变化和老年患者意外拔管事件发生率的影响.方法 选择2013 年1 月 ~2015 年6 月我院 ICU进行气管插管人工气道的患者40 例作为对照组, 实施常规风险防范管理; 选择2015 年7 月~2017 年2 月我院ICU进行气管插管人工气道的患者40 例作为观察组, 实施 FMEA 模式进行风险防范管理.对比两组RPN值变化和患者意外拔管事件发生率.结果 观察组 RPN 值评分低于对照组, 差异有统计学意义(P<0. 05); 观察组患者意外拔管事件发生率低于对照组, 差异有统计学意义(P <0. 05).结论 人工气道风险防范管理中引入FMEA模式可显著减小风险, 尽可能降低老年患者意外拔管事件发生率, 确保患者气管插管人工气道安全性, 值得临床大力推广.“,”Objective To assess the effect of failure mode and effect analysis (FMEA) on risk priority number (RPN) score and the incidence of accidental extubation in patients with artificial airway risk prevention management. Methods A total of 40 patients undergoing tracheal intubation between January 2013 and June 2015 were selected as control group. Routine risk prevention and management was implemented in the control group. A total of 40 patients undergoing tracheal intubation between July 2015 and February 2017 were selected as observation group. FMEA for risk prevention and management was used in the observation group. RPN score and incidence of accidental extubation in two groups were compared. Results The RPN score in the observation group was lower than that in the control group (P<0. 05). The incidence of accidental extubation in the observation group was lower than that in the control group (P<0. 05). Conclusion The use of FMEA in artificial airway risk prevention management can significantly reduce the risk and the incidence of accidental extubation in patients with tracheal intubation.
