不同睡眠体位对OSAHS患者呼吸暂停低通气指数的影响

Effect of different sleep positions on the apnea hypopnea index of OSAHS patients

目的 了解睡眠状况下OSAHS患者不同体位对呼吸暂停低通气指数（AHI）的影响.方法 于2015年5—7月选取长沙某三级甲等医院耳鼻喉科门诊和住院部收治的98例OSAHS患者为研究对象,利用多导睡眠检测仪观察其不同体位下AHI的变化,并进行比较.结果 98例患者,取右侧卧位时AHI为（16.51±42.08）,左侧卧位时为（20.05±66.11）,仰卧位时为（22.04±86.39）,俯卧位时为（53.31±122.88）.患者睡眠状态下俯卧位与右侧卧位、左侧卧位、仰卧位两两比较差异均具有统计学意义（P〈0.05）.结论 右侧卧位为OSAHS患者睡眠状态时的最佳体位,能有效改善患者上气道阻塞的压力,减少患者睡眠期间的呼吸暂停、低通气的次数.

Objective To explore the effects of different sleep positions on the apnea hypopnea index （AHI） of obstructive sleep apnea hypopnea syndrome （OSAHS） patients under the state of sleep. Methods Totally 98 OSAHS patients from the ENT clinic and the inpatient department of a tertiary hospital of Changsha from May to July 2015 were selected as the research objects. By using polysomnography detection instrument, the AHI index of patients under different sleeping postures were observed and compared between two groups. Results For 98 patients, the AHI index was （16.51±42.08） in their right lateral position, the AHI index was （20.05±66.11） in left lateral position, AHI index was （22.04±86.39） in supine position, and the AHI index was （53.31±122.88） in prone position. The differences of AHI index in prone position were statistically significant compared with the right lateral position, the left lateral position and supine position （P 〈 0.05）. Conclusions The right lateral position is the best position for OSAHS patients under the state of sleep, and it can decrease upper airway pressure and reduce the sleep apnea and hypopnea during sleep.
