Keyword:  打鼾香草扁桃酸低氧血症;
Abstract: 目的:了解打鼾者夜间低氧血症对尿香草扁桃酸(VMA)水平的影响.方法:采用病例-对照的研究方法,分别收集打鼾合并夜间低氧血症的患者和打鼾血氧饱和度正常者夜间8 h尿液和24 h总尿液.夜间低氧血症分度:SaO2≥94%为正常组,85%≤SaO2<94%为轻度低氧血症组,65%≤SaO2<85%为中度低氧血症组,SaO2<65%为重度低氧血症组.尿VMA的测定采用重氮显色法.结果:(1)8 h尿VMA的水平和24h时尿VMA的水平在正常血氧饱和度组、轻度低氧血症组、中度低氧血症组均呈递增的趋势,且存在统计学差异(P<0.05).(2)单因素相关性分析结果显示,夜间8 h尿VMA与夜间最低血氧饱和度的相关系数为-0.19,且差异具有显著意义(P=0.040);24 h尿VMA与夜间最低血氧饱和度的相关系数为-0.15,且差异具有显著意义(P=0.048).结论:研究结果提示,轻、中度缺氧的打鼾患者尿VMA水平随血氧饱和度的降低而增高.
