不同梗阻平面对儿童阻塞性睡眠呼吸暂停低通气综合征的影响

Effect of different obstruction plane on obstructive sleep apnea-hypopnea syndrome in children

目的探讨鼻咽平面(腺样体)与口咽平面(扁桃体)的阻塞对儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的影响。方法经多导睡眠监测确诊的OSAHS儿童患者62例,分为单纯扁桃体肥大组(24例)和单纯腺样体肥大组(38例),对不同梗阻平面阻塞的影响进行分析。结果单纯腺样体肥大组在呼吸暂停/低通气指数(AHI)、最低血氧饱和度(LSaO2)、≥3%的氧减指数(≥3%ODI)明显高于单纯扁桃体肥大组(P<0.05)。腺样体肥大程度与儿童OSAHS的严重程度关联性较大。结论鼻咽平面的梗阻是儿童OSAHS的主要影响因素。

Objective To explore the effect of different obstruction planes on obstructive sleep apnea-hypopnea syndrome（OSAHS） in children. Methods A total of 62 children with OSAHS was divided into two groups of A（24 cases） with tonsil hypertrophy only and B（38 cases） with adenoidal hypertrophy only. The effect of different obstruction planes on OSAHS was analyzed. Results The apnea-hypopnea index（AHI）, lowest oxygen saturation （ LSaO2 ）, ≥ 3 % oygen dcrease index （ ≥ 3 %ODI） were higher in group B than those in group A （P〈0.05）. The severity of adenoidal hypertrophy was closely correlated with OSAHS. Conclusion The nasopharyngeal obstruction by adenoid hypertrophy is the major factor to influence OSAHS.
