摘要
目的 探讨对阻塞性睡眠呼吸暂停综合征 (obstructivesleepapneasyndrome,OSAS)有效的颌下经皮电刺激颏舌肌部位。方法 应用局部解剖提供颏舌肌及支配神经的刺激部位 ,1 1例健康人和 9例OSAS患者清醒状态下颌下恒流刺激 ,对刺激点半径、刺激强度及颌下皮肤厚度进行比较 ,并对 9例舌后咽 (retrotonguebasepharynx ,RTBP)狭窄的OSAS患者进行睡眠颌下经皮电刺激效果对比。结果 选定的颏下及下颌角内侧两刺激部位 ,能有效刺激颏舌肌 ,两刺激点半径、刺激强度无差异 (P>0 0 5 ) ,并不受颌下皮肤厚度影响。睡眠期颌下电刺激所测呼吸紊乱指标均明显下降 (P <0 0 5 ) ,血氧饱和度指标显著提高 (P <0 0 5 ) ,临床症状改善。结论 选择的颌下电刺激部位经刺激能有效改善OSAS的临床表现和各项呼吸紊乱指标 ,其机制可能是因刺激颏舌肌使舌体向前运动而开放咽腔的结果。
Objective To investigate the effective position of submaxillary transcutaneous electrical stimulation for obstructive sleep apnea syndrome (OSAS) Methods With fixed provocative locus of genioglossus and its controlling nerve, 11 normal healthy men and 9 patients with OSAS during awakening were studied to disclose the effect of submaxillary constant current stimulation under different stimulative radius or intensity and thickness of submaxillary skin The effects of electric stimulation in 9 OSAS patients with narrowing of the retrotongue base pharynx level were compared with the control during sleep Results The submental and internal side of mandibular angle was effective loci for stimulating genioglossus Stimulative radius and intensity of both loci were not significantly different ( P <0 05) and no influence of the skin thickness was found During sleep, indices of breath disorder ( P <0 05), oxygen saturation ( P <0 05) and clinical symptoms had significantly improved Conclusion Submaxillary electrical stimulation with fixed provocative locus is effective for the treatment of OSAS The mechanism is perhaps stimulation of genioglossus pushes the tongue ahead and opens the pharyngeal cavity
