A prospective study was carried out on 110 children undergoing tonsillectomy or adenotonsillectomy to evaluate the usefulness of computer assisted pulse oximetry (POM) as a screening tool for nocturnal obstructive sleep apnea episodes. Twenty-one healthy age-matched children served as a control group. A self-designed software (CAPO version 1.0) was used to analyse collected oximetric data. Pre-operatively up to 25% of children showed a characteristic pattern of repeated oxygen desaturations related to partial or complete airway obstruction, which was not seen in the matched group. Thirty-one percent had an oxygen desaturation index (ODI) of more than 2 phases/h, being significantly higher than in the matched group. These children could not be identified from history or clinical examination with an acceptable sensitivity. A second monitoring has been performed in 32 patients 5 days after surgery. The nocturnal cyclic oscillations of oxygen saturation resolved in almost all cases. Computer assisted POM is useful in predicting and grading nocturnal obstruction and adds decision making data for the treatment in children suspected of suffering from obstructive sleep apnea.
对110名接受扁桃体切除术或腺样体扁桃体切除术的儿童进行了一项前瞻性研究，以评估计算机辅助脉搏血氧饱和度测定法（POM）作为夜间阻塞性睡眠呼吸暂停发作筛查工具的有效性。21名年龄匹配的健康儿童作为对照组。使用自行设计的软件（CAPO版本1.0）分析收集到的血氧饱和度数据。术前，高达25%的儿童表现出与部分或完全气道阻塞相关的反复氧饱和度下降的特征模式，而在匹配组中未观察到这种情况。31%的儿童氧饱和度下降指数（ODI）超过2次/小时，显著高于匹配组。通过病史或临床检查无法以可接受的敏感性识别出这些儿童。32名患者在术后5天进行了第二次监测。几乎所有病例中夜间血氧饱和度的周期性波动都得到了解决。计算机辅助POM有助于预测和分级夜间阻塞，并为疑似患有阻塞性睡眠呼吸暂停的儿童治疗提供决策数据。
