阻塞型睡眠呼吸暂停综合征96例临床分析

Clinical Analysis of 96 Patients with Obstructive Sleep Apnea Syndrome (OSAS)

为观察不同程度的睡眠呼吸暂停综合征病人有关诊断指标与临床表现的相关关系。将多导脑电图仪改装成睡眠多导图监测仪。记录病人整夜睡眠时的脑电、眼动、肌电、心电、口鼻呼吸、胸腹呼吸、血压、脉搏及血氧饱和度（ＳａＯ２）等，并进行分析。阻塞型睡眠呼吸暂停综合征（ＯＳＡＳ）９６例，根据程度将其分为轻、中、重３个组。其呼吸暂停指数（ＡＨＩ）和ＳａＯ２的均值分别为１２．７７，７８．５％；３０．９９，７２．６２％；７３．９３，５６．８８％；总共低通气时间均值为１３．８８分，３４．９３分，１０３．５９分。说明随着ＡＨＩ的增加，总共低通气时间越长，ＯＳＡＳ的病情越重。肥胖与ＯＳＡＳ密切相关。

urpose: To study the relations between the different degree of diagnostic indexes of OSAS and the clinical manifestations of the patients. Method: EEC, ECG, EMG, eyemovements, blood pressure, pulse rate, mouthnosebreath, chestabdomenbreath and SaO2 of every patient were recorded all night with sleep polygraph by means of reequiped electroencephalograph and then analysed. Results: the averages of apnea hypnosis indexes (AHI) and SaO2 of mild, moderate and severe groups were 12.77,78.5%; 30.99,72.62% and 73.93,56.88% respectively. The averages of general hypoxic ventilatory time were 13.88,34.93 and 103.59 minutes respectively. Conclusions (1) The higher the AHI and the longer the general hypoxic ventialatory time, the severer the patient's condition of OSAS. (2) OSAS relates closely to obesity.
