Abstract

Polysomnography (PSG) is the gold standard for diagnosing obstructive sleep apnea (OSA) in children but not always available. Abbreviated exams exist, such as respiratory polygraphy (RP), but are less accurate for OSA diagnosis. Video recording (video-RP) may provide a more precise estimation of the total sleep time (TST) compared to RP alone. The aim of this study was to evaluate the diagnostic power of video-RP compared to RP and PSG.

Overall, 68 PSG from 68 children (median [1st; 3rd quartile] age of 9 [7; 12]years) were included. After the interpretation of the initial PSG, the analysis was deleted, and the recording was analyzed by taking into account only the respiratory signals and video recording (video-RP). Finally, a third interpretation, after deleting the previous, was performed by considering only the respiratory signals (RP).

The median [1st; 3rd percentile] obstructive apnea-hypopnea index (OAHI) was underestimated in video-RP (4.1 [2.7; 6.5]/h) as well as RP (4.0 [2.7; 6.2]/h) compared to PSG (4.8 [2.9; 6.7]/h, p = 0.02 and p = 0.01, respectively). Bland-Altman analysis confirmed the underestimation of OAHI by video-RP and RP compared to PSG, the magnitude of the difference being −0.69 ± 2.16 and −0.78 ± 2.12, respectively. OSA severity grading was different when scored by video-RP and RP compared to PSG in 14 (21 %) children.

Video-RP underestimated the OAHI compared to PSG, similar to RP. Adding the video recording did not improve the diagnostic power of RP for the diagnosis of OSA. The use of video-RP at home should be investigated in future studies.

期刊介绍： Sleep Medicine aims to be a journal no one involved in clinical sleep medicine can do without. A journal primarily focussing on the human aspects of sleep, integrating the various disciplines that are involved in sleep medicine: neurology, clinical neurophysiology, internal medicine (particularly pulmonology and cardiology), psychology, psychiatry, sleep technology, pediatrics, neurosurgery, otorhinolaryngology, and dentistry. The journal publishes the following types of articles: Reviews (also intended as a way to bridge the gap between basic sleep research and clinical relevance); Original Research Articles; Full-length articles; Brief communications; Controversies; Case reports; Letters to the Editor; Journal search and commentaries; Book reviews; Meeting announcements; Listing of relevant organisations plus web sites.
