汉化版Munro成人手术室压疮风险评估表在全身麻醉手术中的应用研究

摘要

目的 探讨汉化版Munro成人手术室压疮风险评估表(以下简称Munro量表)、Braden量表、钱维明手术压疮评估量表(以下简称自制量表)在全身麻醉手术患者中使用的临床效度.方法 由3名调查员分别应用Munro量表、Braden量表、自制量表对261例全身麻醉手术患者在术前、手术结束时、出麻醉恢复室时进行压疮风险评估,计算各评估工具的灵敏度、特异度、阳性预测值、阴性预测值.结果 Munro量表的最佳临界值在术前、手术结束时、出麻醉恢复室时分别为8.0、24.5、28.5分,Braden量表最佳临界值术前、手术结束时、出麻醉恢复室时分别为18.5、11.5、13.5分;自制量表最佳临界值术前、手术结束时、出麻醉恢复室时分别为12.5、13.5、13.5分;三者术前的受试者工作特征(ROC)曲线下面积分别是0.653、0.596、0.652,手术结束时ROC曲线下面积分别是0.872、0.548、0.792,出麻醉恢复室时ROC曲线下面积分别是0.868、0.773、0.813.结论 Munro量袁较Braden量表、自制量表可能更适合手术患者的压疮风险评估,但术前风险评估部分有待改良.%Objective To test the clinical validity of use of the Chinese version of Munro adult pressure ulcer risk-assessment scales (Munro scales),Braden scales,Qian Weiming operation pressure ulcer risk-assessment scales (self-designed scales) in the patients with general anesthesia surgery.Methods Three investigators respectively used the Munro scales,Braden scales and self-designed scales to conduct the pressure ulcer risk-assessment on 261 patients with general anesthesia surgery before operation,at the end of operation and at exiting from anesthesia recovery room.The sensitivity,specificity,positive predictive value and negative predictive value of each assessment tool were calculated.Results The best critical values of the Munro scales before operation,at the end of operation and at exiting from anesthesia recovery room were 8.0,24.5,28.5 points respectively;which of the Braden scale were 18.5,11.5,13.5 points respectively;which of self-made scale were 12.5,13.5,13.5 points respectively.The area under the ROC curve of the three different scales at the beginning of the operation above was 0.653,0.596,0.652.The area under the ROC curve of the three different scales at the end of the operation above was 0.872,0.548,0.792.The areas under the ROC curve of the three different scales before operation were 0.868,0.773 and 0.813 respectively.Conclusion The Chinese version of Munro scales is more suitable for the assessment of operative patient's pressure ulcer risk than the Braden scale and self-designed scales,but the preoperative risk assessment needs to be improved.
