Abstract:
Objective To analyze the clinical characteristics and polysomnographic(PSG)features of children with sleep-related hypoventilation disorder(SRHD),facilitate its auxiliary diagnosis,and explore the therapeutic effects of non-invasive positive pressure ventilation(NPPV)on SRHD children.Methods A retrospective study was conducted on the medical records of 16 children diagnosed with SRHD who were admitted and treated in the Department of Respiratory Diseases,Children's Hospital Affiliated to Capital Institute of Pediatrics,from July 2016 to June 2024.Additionally,69 children with severe obstructive sleep apnea(OSA)who visited the Department of Respiratory Diseases and Otolaryngology at the same hospital from July 2021 to June 2022 and met the inclusion criteria were enrolled to compare clinical and PSG characteristics between SRHD and OSA children.The therapeutic effects of NPPV were evaluated.Results(1)Among 16 SRHD children,4(25.0%)presented with cyanosis,9(56.3%)with dyspnea,and 5(31.3%)with convulsions.(2)Eleven SRHD children completed PSG+PetCO2,showing PSG characteristics consistent with severe OSA.(3)Compared with severe OSA children,SRHD children had lower proportion of rapid eye movement(REM)sleep,mean and minimum oxygen saturation,and higher obstructive hypopnea index,obstructive apnea-hypopnea index(OAHI),and apnea-hypopnea index(AHI)(P<0.05).(4)When compared with 25 severe OSA children with OAHI>25,the ratio of obstructive apnea to hypoventilation was approximately 1:30 in SRHD children,with more significant decrease in pulse oxygen saturation(P<0.05).(5)After NPPV treatment for 12 SRHD children,clinical symptoms and PSG indicators significantly improved(P<0.05).Conclusions The 3 main symptoms in SRHD children are dyspnea,convulsions,and cyanosis.For children with unexplained cyanosis and PSG meeting severe OSA criteria,especially those with predominantly obstructive hypoventilation events and significant SpO2 reduction,PetCO2 monitoring should be performed to detect SRHD early.NPPV improves clinical symptoms,reduces sleep-related events,increases sleep-time SpO2,and enhances sleep safety in SRHD children.
