品管圈对心胸外科护士呼吸机报警认知与处理的影响

The Impact of Quality Control Circles on Cardiothoracic Surgery Nurses'Awareness and Management of Ventilator Alarms

目的探讨品管圈活动对护士在呼吸机报警认知与处理方面的影响,确保呼吸机治疗的安全。方法采用随机数字表法选取2022年1—5月106例机械通气患者为开展品管圈活动前设为对照组;将2022年6—10月114例机械通气患者为开展品管圈活动后设为观察组。对照组采取传统护理方法,观察组采取品管圈质量改进活动,探讨重症监护室护士对呼吸机报警识别与处理不及时、不正确的原因,从认知、行为、管理及流程4个方面进行分析、讨论,设定目标,制订和实施对策,并对实施的过程进行质控。对比2组相同时间段内呼吸机报警次数、护士处理时间及不良事件发生情况,以及护士掌握报警知识情况。结果心胸外科护士对呼吸机报警原因掌握知晓率由实施前52.50%提高到97.50%;理解呼吸机报警英文意义知晓率由实施前41.25%提高到93.75%;报警处理正确率由实施前56.25%提高到95.65%;在报警次数、护士对报警处理时间方面比较,差异有统计学意义(P<0.05)。结论品管圈活动提高了心胸外科护士对呼吸机报警认知程度和呼吸机报警及时识别与防范处理的能力。

Objective To explore the influence of the quality control circle activity on nurses'cognition and handling of ventilator alarms to ensure the safety of ventilator therapy.Methods A total of 116 mechanically ventilated patients from January 2022 to May 2022 were selected with random number table method as the control group before the implementation of quality control circle activities.A total of 114 mechanically ventilated patients from June 2022 to October 2022 were selected with random number table method as the observation group after the implementation of quality control circle activities.The control group adopted the traditional nursing method,and the observation group adopted the quality improvement activities of the quality control circle,grasping the reasons affecting nurses'untimely and incorrect identification and treatment of ventilator alarms by ICU nurses,analyzing and discussing the 4 aspects of cognition,behavior,management and process,setting goals,formulating and implementing countermeasures,and conducting quality control on the process of implementation.The number of ventilator alarms,nurses'handling time and occurrence of adverse events in the same time period of patients in both groups were compared and studied,as well as nurses'knowledge of alarms.Results The knowledge rate of cardiothoracic nurses about the cause of ventilator alarms increased from 52.50% to 97.50% before implementation;the knowledge rate of understanding the meaning of ventilator alarms in English increased from 41.25% to 93.75% before implementation;the correct rate of alarm handling increased from 56.25% to 95.65% before implementation;there were also significant differences in the number of alarms and nurses'handling time of alarms when compared(P<0.05).Conclusion The quality control circle activity improved cardiothoracic surgery nurses'awareness of ventilator alarms and the ability to identify and prevent the handling of ventilator alarms in a timely manner.
