Analysis of polysomnography outcomes and clinical data in seventy-four children

Objective To discuss the clinical feature and diagnosis of pediatric obstructive sleep apnea hypopnea syndrome(OSAHS). Methods Collected the clinical data of 74 suspected OSAHS children-including history of sleep related breathing disorder,body height,weight and specialized examinations of tonsils and adenoid,before performing polysomnography(PSG). Results According to the outcomes of PSG,these children were divided two groups:non-OSAHS group (obstructive apnea index,OAI1 /h),12 cases,and OSAHS group(OAI≥1/h,or apnea hypopnea index,AHI≥5/h associated the lowest pulse oxygen saturation,LSpO2 92%),62 cases. The two groups had no statistically significant differences in clinical manifestations,specialized examinations and body mass index (BMI). Conclusion The clinical manifestations and specialized examinations can't reliably distinguish children with OSAHS from those with simple snore. PSG plays an important role in exact diagnosis of pediatric sleep related breathing disorder; obesity is not the main cause of pediatric OSAHS.
