摘要
目的:探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者悬雍垂腭咽成形术(UPPP)后PSG观察指标的改变。方法:对行UPPP手术的20例OSAHS患者于手术前后分别进行PSG监测。结果:①与术前比较,UPPP术后PSG监测观察指标中睡眠呼吸暂停低通气指数(AHI)(P<0.01)、最低SaO2(P<0.01)、平均SaO2(P<0.01)、平均睡眠呼吸暂停低通气时间(P<0.05),均有不同程度的改善;②UPPP手术后,PSG监测观察指标睡眠时相构成比的改变主要在与从S1期转入到S2期;③PSG监测观察指标中,AHI与最低SaO2、平均SaO2、平均最长睡眠呼吸暂停低通气时间之间均具有相关性,但是前两者之间的相关性更有统计学意义,且手术前后AHI的减小值与最低SaO2的升高值之间同样具有相关性。结论:对于患者病情轻重以及手术疗效的评价,SaO2是较睡眠呼吸暂停低通气时间更为敏感的指标,UPPP术后睡眠构成比的变化主要在于从S1期转入到S2期。
Objective： To study the change of polysomnography （PSG） parameters of obstructive sleep apnea hypopnea syndrome（OSAHS） patients before and after uvulopalatopharyngoplasty（UPPP） operation. Method.. Having PSG detection for this 20 OSAHS patients both before and after UPPP operation. Result： OAfter UPPP operation,AHI（ P （0.01）, average SaO2 （ P〈0.01）, Min SaOz （ P 〈0.01）, and apnea time contrast （ P〈0. 0S）have improvements; ②After UPPP operation, the change of sleep stage mainly S2 stage replaced S1 stage. ③In observation index of PSG, both the relationship between AHI and oxygen saturation and the relationship between AHI and apnea time have correlation, but correlation of the former has more significant difference in statistics. The change of AHI and MinSaO2 after UPPP operation has correlation also. The secant plane of oropharynx can be regarded as the predictive index for OSAHS severity and guideline for UPPP operation, but the change of oropha- ryngeal secant plane after operation can not be used as the predicitive index for therapeutic effectiveness. Conclusion： So we treat oxygen saturation as a more sensitive marker than apnea time in predicting severity degree of OSAHS. After UPPP operation, the change of sleep stage mainly S2 replaced S1 stage.
