Early diagnosis of Sleep Disordered Breathing (SDB) is crucial. Polygraphy (PG) effectively identifies Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) in children, particularly those with neuromuscular disease or obesity.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Diagnostic Tools
Background:
- Early diagnosis of Sleep Disordered Breathing (SDB) is essential for timely intervention.
- Polygraphy (PG) is a reliable and accessible diagnostic method for SDB.
Purpose of the Study:
- To describe and analyze polygraphy (PG) results in children over 1 year old with suspected SDB.
- To evaluate the prevalence and characteristics of SDB in a pediatric population.
Main Methods:
- Retrospective analysis of 190 PG studies from children and adolescents in Concepcion, Chile (2011-2017).
- Collection of demographic, clinical, and polygraphic variables.
- Descriptive statistics, Spearman's Rho correlation for AHI and oxygen saturation.
Main Results:
- The study analyzed 190 PG studies in children aged 1.0-20.6 years (61% males).
- 55.3% of studies showed abnormal PG results, with 53.3% diagnosed with mild Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS), 30.5% moderate, and 16.2% severe.
- Significant associations were found between the apnea-hypopnea index (AHI) and oxygen saturation parameters (mean, minimum, and <90%). Higher AHI was noted in obese patients and those with neuromuscular disease.
Conclusions:
- A high prevalence of OSAHS was observed in at-risk pediatric patients, particularly those with neuromuscular disease and obesity.
- Polygraphy (PG) is an accessible and implementable tool for diagnosing SDB in pediatric patients within a public hospital setting.
- Findings suggest PG's utility can be extrapolated to other healthcare centers for pediatric SDB diagnosis.
