脉搏传导时间在儿童睡眠呼吸阻塞诊断中的应用

HypnoPTT in the diagnosis of the sleep respiratory disease in children

目的探讨适合于儿童的睡眠呼吸监测法。方法38例儿童患者采用脉搏传导睡眠监测仪HypnoPTT,对照组31例儿童患者采用多导睡眠监测(polysomnography,PSG)。两组在检测参数、操作方法等方面进行对比。结果除了共同参数外,HypnoPTT另可测得吸气受限(inspiratoryflowlimitation,IFL)和皮层下微觉醒,能可靠测出阻塞性事件,HypnoPTT接线通道更少。结论HypnoPTT操作方便,对睡眠干扰小,监测结果可靠,更适合于儿童应用。脉搏传导时间对阻塞性睡眠呼吸疾病具有诊断意义。

OBJECTIVE To explore a more effective method of detecting sleep respiratory events in children. METHODS Thirty-eight children were tested with HypnoPTT and 31 with polysomnography （control）. The test parameters and operative methods were compared. RESULTS In addition to the parameters comm.on to both HypnoPTT and polysomnography, inspiratory flow limitation and spontaneous microarousal can be measured using HypnoPTT and fewer electrodes were needed. CONCLUSION HypnoPTT is a convenient method characterized by less sleep disturbance and credible results, rendering it is especially suitable for pediatric cases. Pulse transit time is a useful parameter for diagnosing the sleep respiratory disease.
