前馈控制护理在心脏手术安全管理及护理中的应用效果

Application Effect of Feedforward Control Nursing in Safety Management and Nursing of Cardiac Surgery

目的:观察前馈控制理论在心脏手术安全管理中的应用及对护理效果的影响。方法:选择接受心脏手术治疗的123例患者为研究对象,随机分为观察组(n=63)和对照组(n=60),对照组实施常规护理,观察组实施前馈控制护理,比较2组患者的护理差错事件发生情况、手术相关并发症发生情况及对护士的护理质量评分,对所有患者开展为期6个月短期随访,比较2组术后心功能康复情况。结果:实施前馈控制护理后,观察组护理差错事件发生率(4.76%)低于对照组的(18.33%)(P<0.05),手术相关并发症发生率6.35%低于对照组的20.00%(P<0.05),各维度护理质量评分均高于对照组(P<0.05);观察组左室射血分数(LVEF)高于对照组[(58.42±5.17)%vs(55.36±5.44)%],左室舒张末期内径(LVDD)小于对照组[(50.25±5.16)mm vs(53.17±5.28)mm],差异有统计学意义;观察组6 min步行试验(6 MWT)大于对照组[(455.35±50.27)m vs(428.32±50.37)m],差异有统计学意义(P<0.05)。结论:前馈控制护理可有效降低心脏手术的护理差错事件及手术相关并发症的发生风险,可显著提升护理质量并促进患者远期心功能康复。

Objective:To observe the application of feedforward control theory in the safety management of cardiac surgery and its influence on the nursing effect.Methods:123 patients who received cardiac surgery were divided into observation group(n=63)and control group(n=60)by random number table method.The control group only carried out routine operation room nursing,while the observation group carried out feedforward control nursing,and compared the occurrence of nursing errors,surgical complications and nursing quality scores of nurses in the two groups,All patients were followed up for a short period of 6 months to compare the recovery of cardiac function between the two groups.Results:Under different nursing modes,the incidence of nursing error events in the observation group was 4.76%lower than that in the control group 18.33%(P<0.05),and the incidence of operation-related complications was 6.35%lower than that in the control group20.00%(P<0.05),and the nursing quality scores in all dimensions were higher than that in the control group(P<0.05);During the follow-up period,LVEF(58.42±5.17)%in the observation group was higher than that in the control group(55.36±5.44)%(P<0.05),LVDD(50.25±5.16)mm was smaller than that in the control group(53.17±5.28)mm(P<0.05),and 6MWT(455.35±50.27)m was larger than that in the control group(428.32±50.37)m(P<0.05).Conclusion:Feedforward control nursing can effectively reduce the risk of nursing errors and complications related to cardiac surgery,significantly improve the quality of nursing and promote long-term cardiac function recovery of patients.
