摘要
目的探讨用于临床的下颌肌群肌电活性的评价指标。方法采用下颌肌肌电图检查与夜间多道睡眠监测（PSG）同步进行的方法，对确诊为阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的50例男性患者进行监测。分析其中15例患者1周前后两次监测的下颌肌电活性比的重测信度；比较50例患者非快动眼睡眠期（NREM）与快动眼睡眠期（REM）下颌肌电活性比的差异，分析下颌肌电活性比与年龄、体质量指数（bodymassindex，BMI）、呼吸紊乱指数（apneahypopneaindex，AHI）、最低血氧饱和度的相关性。结果15例患者的前后两次监测的下颌肌电活性比的重测信度〉0．7。50例患者NREM期下颌肌电活性比平均（x±s，下同）为1．84±0．64，REM期为1．68±0．48，两者进行配对t检验，差异有统计学意义（t=2．849，P=0．006），NREM期大于REM期。运用Pearson相关分析法进行分析，肌电活性比与年龄、AHI以及REM期AHI呈负相关，相关系数依次为-0．336，-0．339，-0．338，P值均〈0．05，而与BMI、最低血氧饱和度无相关性。结论下颌肌电活性比是一个较稳定的指标，在一定程度上能够反应下颌肌肉的活性。
Objective To establish an index that can evaluate the genioglossus muscle activity and investigate the relationship between the genioglossus muscle activity and the severity of patients with obstructive sleep hypopnea apnea syndrome （OSAHS）. Methods Mandibular muscle electromyography （EMG） and polysomnography （PSG） were used in fifty patients with OSAHS. The difference of mandibular muscle activity between the twice muscle activity of fifteen patients and between in non rapid eye movement （NREM） stage and rapid eye movement （REM） stage on fifty patients were analyzed. The relationship between the index and age, body mass index （ BMI）, apnea hypopnea index （ AHI）, and the lowest oxygen saturation was evaluated. Results There was no statistical difference between the twice muscle activtity in fifteen patients. The average index in NREM was 1.84 ± 0. 64 x± s, the same below）, in REM was 1. 68 ＋ 0. 48. The difference of mandibular muscle activity between in NREM stage and REM stage was significant（t = 2. 849, P 〈 0. 05 ）. By pearson test there was relationship between the index and age and AHI, the correlation coefficient was - 0. 336, - 0. 339, - 0.338 and P 〈 0.05 . There was no relationship between the index and BMI and the lowest oxygen saturation. Conclusions This index that is stable can evaluate the mandibular muscle activity to some degree.
