摘要: 目的 评价改良Mallampati分级联合NoSAS问卷筛查阻塞性睡眠呼吸暂停(OSA)的价值。方法 以因睡眠障碍就诊的344例患者为研究对象,测量所有患者的身高、体重、颈围等参数,填写NoSAS量表及评估改良Mallampati分级。对患者均进行PSG记录,根据PSG监测结果中的AHI将患者分为非OSA组(AHI < 5)93例和OSA组251例,OSA组包括轻度OSA组(AHI为5~15)、中度OSA组(AHI为16~30)、重度OSA组(AHI>30)。绘制受试者工作特征(ROC)曲线,分别评估NoSAS评分和NoSAS评分联合改良Mallampati分级对OSA的筛查价值。结果 以NoSAS≥8分为标准筛查OSA组的灵敏度和特异度分别为0.733和0.538;以NOSAS≥9分为标准筛查OSA的灵敏度和特异度分别为0.701和0.624;采用NoSAS联合改良Mallampati分级筛查OSA的灵敏度及特异度分别为0.813和0.710。结论 NoSAS问卷作为一项新的筛查工具,简单便捷。改良Mallampati分级联合NoSAS问卷可明显提高对OSA的筛查敏感性及特异性,有较高的应用价值。

Abstract: Objective To evaluate the value of improved Mallampati grading combined with NoSAS questionnaire in screening for obstructive sleep apnea (OSA).Method A total of 344 patients admitted to our hospital for sleep disorders were studied. All patients were measured for their height, weight, neck circumference and other parameters. NoSAS scores, improved Mallampati grading and polysomnography (PSG) were performed in these patients. According to AHI in PSG monitoring results, patients were divided into non-osa group (AHI < 5) 93 cases and OSA group 251 cases. The OSA group were divided into mild (AHI 5-15), moderate(AHI 16-30) and severe OSA group(AHI>30) according to the PSG result. The ROC curve was plotted to evaluate the screening value of NoSAS and improved Mallampati grading combined with NoSAS for OSA.Result With the NoSAS score of 8 or 9 as cutoffs for analysis, the sensitivity for OSA was 0.733 and 0.701; the specificity for OSA was 0.538 and 0.624, respectively. The sensitivity and specificity of NoSAS combined with improved Mallampati grading for screening OSA were 0.813 and 0.710, respectively.Conclusion As a new screening tool, NoSAS questionnaire is simple and convenient, and has certain screening value to OSA. The improved Mallampati grading combined with NoSAS questionnaire can obviously improve the screening sensitivity and specificity of Osa, and has higher application value. -
