Lee SH, Choi JH, Park IH, et al. Measuring sleep quality after adenotonsillectomy in pediatric sleep apnea. Laryngoscope 2012; 122(9): 2115-21. DOI:10.1002/lary.23356
To demonstrate postoperative changes in sleep quality in children with obstructive sleep apnea (OSA), using both conventional sleep staging and electrocardiogram-based cardiopulmonary coupling (CPC) analysis. The hypothesis is that being electroencephalography (EEG)-independent, CPC may detect changes in sleep quality that traditional sleep architecture analysis cannot.
Adenotonsillectomy led to a significant change in CPC parameters (HFC, LFC), which was paralleled by significant improvements in the apnea-hypopnea and arousal index. Polysomnographic sleep stage parameters other than the arousal index did not reflect postoperative resolution of OSA.
In pediatric OSA, postoperative improvement of sleep quality is more readily discernible by CPC analysis than EEG-based sleep staging. The CPC analysis may have potential advantages in the assessment of sleep quality in pediatric populations.
