睡眠体位与睡眠呼吸暂停类型累计次数的关系

Relationship between sleeping body posture and cumulative number of sleep apnea types

目的探讨睡眠呼吸暂停低通气综合征(SAHS)患者睡眠体位与睡眠呼吸暂停各类型累计次数的关系。方法用初筛睡眠诊断仪监测55例SAHS患者,设定仰卧位、俯卧位、侧卧位和未知体位4种体位,记录各体位发生低通气、阻塞型、中枢型、混合型睡眠呼吸暂停的次数及总累计次数,比较不同体位时睡眠呼吸暂停次数的差异。结果侧卧位各类型呼吸暂停累计次数和总累计次数与其他体位比较差异有统计学意义[侧卧位时各类型睡眠呼吸暂停的次数及总累计次数分别为(0.61±0.25)次、(3.44±1.98)次、(0.84±0.50)次、(1.29±0.58)次、(6.33±2.97)次,P<0.05],仰卧位、俯卧位和未知体位三者比较差异无统计学意义(P>0.05)。结论 SAHS患者取侧卧位可减少睡眠呼吸暂停次数。

Objective To investigate the relationship between sleeping body posture and cumulative number of different sleep apnea types for patients with sleep apnea hypopnea syndrome（SAHS）. Methods Fifty-five patients with SAHS were monitored by portable polysomnography, with four sleeping body positions（supine position,prone position, lateral position, and postural unknown） defined. The sleep apnea times of respective and total for hypoventilation, obstructive, central, mixed sleep apnea in different position were recorded. The differences for the number of times were analyzed. Results Sleep apnea times of respective and total at lateral position showed significant differences（P〈0.05）, when lateral position compared to other positions. The number of times for respective and total of hypoventilation, obstructive, central, mixed sleep apnea at lateral position was（0.61±0.25）,（3.44±1.98）,（0.84±0.50）,（1.29±0.58） and（6.33 ± 2.97）. The other kinds of sleeping positions showed no significant difference（P〈0.05）. Conclusion Patients with SAHS sleeping at lateral position can reduce the times of sleep apnea.
