儿童全身麻醉苏醒期躁动风险量表的汉化及信效度研究

Translation and psychometric evaluation of a risk scale for emergence agitation after general anesthesia in children with strabismus correction surgery

目的汉化儿童全身麻醉苏醒期躁动风险量表(EA风险量表),分析其在斜视矫正术患儿全身麻醉苏醒期躁动风险评估中的信效度。方法征得原作者授权后,采用国际通用的Brislin翻译模型及回译法对EA风险量表进行双人翻译、回译和文化调试,形成中文版EA风险量表;采用便利抽样方法抽取天津医科大学眼科医院279例斜视矫正术患儿进行调查,检验其信效度。结果该量表各条目与总分的相关系数分别为0.759(条目1)、0.707(条目2)、0.686(条目3)、0.654(条目4)(均P<0.01);内容效度指数为0.920,各条目内容效度指数为0.80~1.00。探索性因子分析共提取1个公因子,包含4个条目(年龄、手术方式、术前行为得分及麻醉时间),累计方差贡献率为62.052%。量表躁动风险评分的截断值为10分,此时ROC曲线下面积为0.816,特异度为0.704,敏感度为0.839。该量表的Cronbachα系数为0.819,评分者信度为0.835。结论中文版EA风险量表具有良好的信效度,条目表达简明清晰,易于理解,适合作为临床科室斜视矫正术前患儿全身麻醉术后苏醒期躁动的识别及评估其发生风险的初步筛查工具。

Objective To analyze a Risk Scale for Emergence Agitation After General Anesthesia in Children(the EA risk scale)into simplified Chinese and evaluate the reliability and validity in children with strabismus correction surgery.Methods After obtaining the authorization of the original author,the English version of the EA risk scale was translated,translated back and culturally debugged to form the Chinese version of the EA risk scale.Then 279 children with strabismus correction surgery were selected from a tertiary hospital of ophthalmology in Tianjin and were investigated to validate the scale.Results The correlation coefficients of each item and the total score of the scale were respectively 0.768(item 1),0.717(item 2),0.676(item 3),0.634(item 4)(all P<0.01).Content validity index of the scale was 0.920,and each item was 0.80-1.00.One factors including 4 items were identified using exploratory factor analysis,accounting for 62.052%of the total variance.The optimal cut-off value for the EA risk in children was 10,with the AUG was 0.816,specificity of 0.704,and sensitivity of 0.839.The Cronbachαcoefficient for the total scale was 0.819,and the intraclass correlation coefficient value between the scorers was 0.835.Conclusion The Chinese version of the EA risk scale has good reliability and validity.The items are concise,clear,and easy to understand.It is suitable for clinical departments as a preliminary screening tool to identify emergence agitation after general anesthesia on children with strabismus correction surgery and to assess the risk of its occurrence.
