摘要
目的观察腺样体肥大儿童在行腺样体切除术后睡眠结构的改变。方法对120例行腺样体肥大切除术的儿童,分别于术前及术后1个月行夜间睡眠多导监测,比较手术前后宏观、微观睡眠结构的变化。结果腺样体肥大儿童术后S1期和S2期所占比例与术前比较无统计学意义(P>0.05);SWS期和REM期所占比例增加(P>0.05)。腺样体肥大儿童术后觉醒指数AI(2.8±0.3)较术前(6.3±0.4)明显减小(P<0.01);术后最低SaO2(93.4±1.4)较术前(70.3±1.3)明显提高(P<0.01)。结论腺样体肥大儿童术后宏观睡眠结构无明显改善,微观睡眠结构的改善可能是腺样体肥大儿童术后症状改善的病理生理学基础。
Objective To evaluate the changes of sleep architecture in children with adenoidal hypertrophy after adenoidectomy. Methods From January 2003 to October 2006, polysomnography （PSG） was performed on 120 children with adenoidal hypertrophy before and after adenoidectomy. Various polygraphic parameters describing the macro- structure of sleep and the mierostrueture of sleep were analyzed . Results The S1 and S2 stages were not significantly ehanged after adenoideetomy （ P 〉 0.05）, and the SWS and REM stages inereased in ratio （ P 〉 0.05）. But the arousals index before adenoideetomy was higher than that after adenoideetomy （6.3 ± 0. 4 vs 2.8 ± 0.3, P 〈 0.01 ） and the SaO2 before operations was lower than that after operations （70.3 ± 1.3 vs 93.4 ± 1.4） （ P 〈 0. 01 ）. Conclusions There are no significant differences in the maerostrueture of sleep after adenoideetomy. Improvement of the miemstrueture of sleep in ehildren with adenoidal hypertrophy is the physiopathologieal basis of elinieal relief after adenoideetomy.
