摘要
目的评价阻塞性睡眠呼吸暂停综合征(OSAS)对右心功能的影响以及其相关影响因素。方法选择OSAS患者32例和正常对照组30例,分别行多导睡眠监测仪(PSG)、血氧饱和度(SaO2)和超声心动图右心功能检测,并对19例手术治疗的OSAS患者于术后1周重复检测。结果OSAS中、重度组的SaO2、PSG和超声心动图检测指标与正常组和OS-AS轻度组比较,差异有显著性意义;术后1周OSAS患者的上述指标较术前亦有显著变化;OSAS患者右心Tei指数与夜间呼吸暂停最长时间、肺动脉收缩压和夜间最低血氧饱和度相关性好。结论OSAS患者右心功能不同程度下降;最低血氧饱和度、呼吸暂停时间和肺动脉压对OSAS患者右心功能有重要影响。
Objective To investigate the effect of obstructive sleep apnea syndrome （OSAS） on the right ventricular function and its influencing factors. Methods Parameters of oxygen saturation （SaO2）, respiratory function and right ventricular function were measured in 32 cases with OSAS and 30 normal persons. Results In moderate and severe OSAS groups, there were significant differences in parameters of SaO2, respiratory function and right ventricular function, compared with control group and mild OSAS group. In 19 of 32 patients with surgical treatment, the parameters changed significantly compared with those before operation. Tel index of right ventricle had good relationship with maximal time of apnea （Tmax）, systolic pressure of pulmonary artery （PASP） and minimal oxygen saturation （SaO2min）. Conclusion OSAS can impair right ventricular function; SaO2min Tmax and PASP are important influencing factors.
