目的探讨妊娠各期人体测量、睡眠呼吸变化的特征,为其诊治提供依据。方法选择我院产科门诊建卡登记并分娩的孕妇30例,在孕早、中、晚期观查各孕期孕妇一般生理指标及并进行同期多导睡眠图(PSG)监测。结果随着妊期的进展,孕妇体重、体质指数、颈围均显著升高(P值均<0.05);妊娠期妇女呼吸暂停低通气指数(AHI)、氧减指数(ODI)、血氧饱和度<0.9时间占睡眠时间百分比(SLT90%)、最长呼吸暂停时间(LAT)随着孕期进展均呈进行性升高(P均<0.05),夜间最低血氧饱和度(SaO_2min)随着孕期进行性降低(P<0.05),妊娠中期与早期比较,微觉醒指数(MAI)显著降低(P<0.05),妊娠晚期与早期、中期比较,MAI显著升高(P<0.05)。结论随着孕期的进展,孕妇发生SDB的可能性增大。
Objective To investigate the characteristics of body measurement and sleep-respiration during pregnancy and to provide basis for its diagnosis and treatment. Methods Thirty cases of pregnant women who were enrolled in obstetrics and gynecology clinic and were born in our hospital were enrolled in this study. The general physiological indexes of pregnant women during the first, second and third trimester of pregnancy were observed, and polysomnography (PSG) monitoring was performed. Results With the progress of pregnancy, the body weight, body mass index and neck circumference of pregnant women were significantly increased (P <0.05). The AHI, ODI, (P <0.05). The nighttime minimum oxygen saturation (SaO_2min) increased with pregnancy (P <0.05), and the peak time of apnea (LAT) (P <0.05). The MAI was significantly lower in the third trimester than in the second trimester (P <0.05). Compared with the early trimester and the second trimester, MAI was significantly increased (P <0.05). Conclusion With the progress of pregnancy, pregnant women increased the possibility of SDB.
