脑电双频指数指导重症肺炎机械通气患者镇静效果的研究

A study on the Effect of EEG Dual-frequency Index Guides Sedation in Patients with Severe Pneumonia and Mechanical Ventilation

目的研究脑电双频指数在指导重症肺炎机械通气患者镇静中的应用效果,为护理工作的有效开展提供一定的参考和指引。方法选取中山市医院2018年5月至2019年11月ICU收治的重症肺炎机械通气患者60例,随机数字表法平分为试验组和对照组,每组30例。对照组依据镇静-躁动评分评估镇静深度,试验组依据脑电双频指数评估镇静深度,比较两组患者的最终护理指标。结果通过对比试验组和对照组的护理指标来看,采取脑电双频指数(BIS)指导重症肺炎机械通气试验组患者的镇静效果更好,组间比较差异有统计学意义(P<0.05)。结论BIS指导重症肺炎机械通气患者镇静具有更好的临床实践效果,通过双频分析法对脑电图信号转化为简单的数字报告,能够更加及时、客观地做好镇静评价,对于指导ICU患者护理工作的有效开展起到了重要作用。

Objective To study the application effect of EEG dual-frequency index in guiding sedation in patients with severe pneumonia mechanical ventilation,and to provide certain reference and guidance for the effective development of nursing work.Methods A total of 60 patients with severe pneumonia on mechanical ventilation admitted to ICU in Zhongshan Hospital from May 2018 to November 2019 were selected and divided into the experimental group and the control group by random number table method,with 30 patients in each group.The sedation depth was assessed according to the sedation-agitation score in the control group,and the sedation depth was assessed according to the eeg dual-frequency index in the experimental group,and the final nursing indicators of patients in the two groups were compared.Results By comparing the nursing effect of the BIS group and the RASS group,the sedation effect of the patients with severe pneumonia mechanical ventilation was guided by BIS(P<0.05).Conclusion The EEG bispectral index guides sedation in patients with severe pneumonia with mechanical ventilation has better clinical practice effects.The dual-frequency analysis method is used to convert the EEG signals into simple digital reports.The ability to do sedative evaluations in a more timely and objective manner has played an important role in guiding the effective development of ICU patient care.
