摘要
目的探讨重症超声监测膈肌位移对重症加强护理病房(ICU)机械通气患者撤机能力的预测价值。方法回顾性分析我院2018年5月~2019年12月收治的100例呼吸衰竭患者的临床资料,根据撤机情况分为撤机成功组(77例)与撤机失败组(23例),使用超声仪器测量患者膈肌位移情况,受试者工作特征(ROC)曲线评价膈肌位移对ICU机械通气患者撤机能力的预测价值。结果撤机失败组0.1 s气道闭合压(P0.1)、浅快呼吸指数(RSBI)高于撤机成功组,左侧膈肌位移、右侧膈肌位移、平均膈肌位移低于撤机成功组,差异均有统计学意义(P<0.05);经ROC曲线分析,P0.1所得ROC曲线下面积(AUC)为0.831,最佳截断值为2.50 cmH2O时,敏感度为0.739,特异度为0.299;RSBI所得AUC为0.839,最佳截断值为45.40时,敏感度为0.783,特异度为0.208;左侧膈肌位移所得AUC为0.904,最佳截断值为0.77 cm时,敏感度为0.870,特异度为0.234;右侧膈肌位移所得AUC为0.901,最佳截断值为1.12 cm时,敏感度为0.826,特异度为0.208;平均膈肌位移所得AUC为0.909,最佳截断值为1.00 cm时,敏感度为0.913,特异度为0.494。结论重症超声监测膈肌位移在预测ICU机械通气患者撤机能力中具有较高的应用价值。
Objective To investigate the value of severe ultrasound monitoring of excursion of diaphragm in prediction of weaning ability in patients with mechanical ventilation in intensive care unit(ICU).Methods The clinical data of 100 patients with respiratory failure who admitted to our hospital from May 2018 to December 2019 were retrospectively analyzed,and they were divided into successful withdrawal group(77 cases)and failed withdrawal group(23 cases)according to withdrawal situation.The excursion of diaphragm of patients was measured by ultrasound instruments,and the ROC curve was used to evaluate the predictive value of excursion of diaphragm in weaning ability of patients with mechanical ventilation in ICU.Results The 0.1 s airway occlusion pressure(P0.1)and rapid-shallow-breathing index(RSBI)in failed withdrawal group group were higher than those in successful withdrawal group,and the left excursion of diaphragm,right excursion of diaphragm and mean excursion of diaphragm in failed withdrawal group group were lower than those in successful withdrawal group(P<0.05);After analysis of the ROC curve,the area under the ROC curve(AUC)obtained by P0.1 was 0.831,when the optimal cutoff value was 2.50 cmH2O,the sensitivity was 0.739 and the specificity was 0.299.The AUC obtained by RSBI was 0.839,when the optimal cutoff value was 45.40,the sensitivity was 0.783 and the specificity was 0.208.The AUC obtained by left excursion of diaphragm was 0.904,when the optimal cutoff value was 0.77 cm,the sensitivity was 0.870 and the specificity was 0.234.The AUC obtained by right excursion of diaphragm was 0.901,when the optimal cutoff value was 1.12 cm,the sensitivity was 0.826 and the specificity was 0.208.The AUC obtained by mean excursion of diaphragm was 0.909,when the optimal cutoff value was 1.00 cm,the sensitivity was 0.913 and the specificity was 0.494.Conclusion Severe ultrasound monitoring of excursion of diaphragm has higher application value in prediction of weaning ability in patients with mechanical ventilation in ICU.
