咽通道管治疗阻塞性睡眠呼吸暂停综合征

目的探讨用自行设计的咽通道管治疗阻塞性睡眠呼吸暂停综合征（obstructivesleepapneasyndrom,OSAS）的效果。方法利用咽通道管于1995年5月～1999年8月共治疗57例OSAS患者，治疗前后用国产GKD-405A六导睡眠监测呼吸暂停指数、低通气指数、呼吸紊乱指数、最长呼吸暂停时间、最低血氧饱和度、监测期间血氧饱和度大于90%时间的百分率和鼾声响度7项指标。结果治疗后最长呼吸暂停时间由（54.82±20.83）s降至（25.74±9.50）s，呼吸紊乱指数由70.82±18.06降至30.00±10.10，最低血氧氧饱和度由（62.36±11.53）%提高到（78.68±12.09）%，鼾声响度由(84.32±18.51)dB降至(32.64±10.16)dB，均较治疗前有明显改善(P<0.05～0.001，t值2.204～15.290)。掌握自行戴管技术的成功率为87.72%（50/57），长期置管率（半年以上）为72.73%（32/44）。结论本疗法对重症OSAS患者有明显疗效，可作为一种行之有效的非手术方法推荐。

Pharyngeal passage tube treatment for obstructive apnea syndrome

Objective　To investigate the therapeutical effect of pharyngeal passage tube for OSAS. Methods　Fifty-seven patients were treated during May 1995 to August 1999. All patients were examined by GKD-405 A polysomnography for apnea index (AI), hypnea index (HI), AHI (AI+HI) at cetera 7 items index before and after pharyngeal passage tube treatment. Results　After treatment, the longest time of apnea shortened from (54.82±20.83) s to (25.74±9.50) s, the AHI lessened from 70.82±18.06 to 30.00±10.10, the oxygen desaturation increased from (62.36±11.53) % to (78.68±12.09)%. After treatment, the recorded parameters showed obvious therapeutical effect (P＜0.05～0.001, t values is from 2.20 to 15.29, the snore loudness of all patients dropped from (84.32±18.51) dB to (32.64±10.16) dB. The therapeutical successful rate was 87.72%. The long-term use rate (over 6 months) was 72.73%. Conclusion　The pharyngeal passage tube has obvious effect for patients suffering from severe OSAS. It is recommended for the treatment of OSAS as a concervative method.
