应用"应力环"降低心电监护仪误报警率的效果评价

Evaluation of the effect of"Stress Ring"to reduce the error alarm rate of ECG monitor

目的应用"应力环"固定心电监护仪导联线,减少心电监护仪使用过程中生命体征误报警情况的发生。方法对我科2018年3月至2019年2月应用心电监护仪的200例患者,按照随机数字表法分为对照组和试验组各100例。对照组采用常规方法进行心电监护仪的连接及观察,试验组在此基础上加用导联线盘成"应力环"的方法进行心电监护仪的连接固定,比较2组患者在行心电监护期间的生命体征心率/律和呼吸误报警现象的差异,比较护士工作量、汉密尔顿焦虑量表得分及护士满意度的变化。结果2组在心率/律和呼吸的误报警次数方面比较差异有统计学意义(χ^(2)值为35.835、109.368,P<0.01),试验组患者监护后焦虑量表得分及满意度得分分别为(22.340±4.016)、(85.702±4.653)分,均显著优于对照组的(27.340±7.667)、(81.301±4.773)分,差异有统计学意义(t值为4.216,P<0.05)。结论在患者应用心电监护仪期间将导联线盘成"应力环"可以有效降低心电监护仪生命体征监测中心率/律、呼吸误报警的现象,降低护士工作量,提高护士满意度,降低患者焦虑情绪。

Objective To reduce the occurrence of false alarm of vital signs during the use of ECG monitor by using stress ring to fix the lead wire of ECG monitor.Methods 200 patients who used ECG monitor in our department from March 2018 to February 2019 were intervened by two methods.The control group(n=100)was connected and observed by routine method.The experimental group(n=100)was added with lead wire to form"stress loop"on the basis of this method.Methods The connection and fixation of ECG monitors were carried out.The differences of vital signs,heart rate/rhythm and respiratory false alarm between the two groups during ECG monitoring were compared,and the changes of nurses'workload,Hamilton anxiety score and satisfaction were compared.Results There were significant differences in heart rate/rhythm and respiratory false alarm between the two groups(P<0.05).The scores of anxiety,nurses'workload and satisfaction in the experimental group were significantly improved.Conclusion During the application of ECG monitor,the lead wire coiled into"stress ring"can effectively reduce the ECG monitor vital signs monitoring center rate/rhythm,respiratory false alarm phenomenon,reduce the workload of nurses,improve the satisfaction of nurses,and reduce anxiety of patients.
