Insights
Children with high-risk obstructive sleep apnea (OSA) undergoing adenotonsillectomy face respiratory complications. Preoperative polysomnogram (PSG) findings like high apnea-hypopnea index (AHI) and abnormal oxygen/carbon dioxide levels predict these risks.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Anesthesiology
Background:
- Obstructive sleep apnea (OSA) is a common condition in children.
- Adenotonsillectomy (AT) is a primary treatment for pediatric OSA.
- High-risk OSA patients may experience significant postoperative respiratory complications.
Purpose of the Study:
- To identify patient characteristics and polysomnogram (PSG) parameters linked to postoperative respiratory complications after AT in children with high-risk OSA.
- To stratify risk for adverse respiratory outcomes in this vulnerable pediatric population.
Main Methods:
- A retrospective case series with chart review was conducted.
- Included were pediatric patients (<18 years) with high-risk OSA (AHI > 30, O2 nadir < 80%, or peak CO2 > 60 mmHg) undergoing AT.
- Primary outcomes assessed were major respiratory intervention, prolonged hospitalization, and ICU admission.
Main Results:
- 307 children met inclusion criteria; 8.1% required major respiratory intervention and 9.7% required ICU admission.
- Neuromuscular disease, higher obstructive apnea-hypopnea index (oAHI), elevated peak CO2, and lower O2 nadir were associated with major interventions and ICU admission.
- Younger children (0-2 years) and those with neuromuscular disease had a higher risk of prolonged hospitalization and ICU stay.
Conclusions:
- Preoperative PSG parameters, including oAHI, oxygen saturation, and carbon dioxide levels, are crucial for predicting postoperative respiratory complications in high-risk pediatric OSA patients.
- Neuromuscular disease and young age are significant risk factors for severe postoperative outcomes.
- Clinicians must consider a comprehensive set of PSG parameters, not just oAHI, for risk assessment and management planning.
Objective:
Identify patient characteristics and polysomnogram (PSG) parameters associated with postoperative respiratory complications after adenotonsillectomy (AT) among children with high-risk obstructive sleep apnea (OSA).
Study Design:
Case series with chart review.
Setting:
Tertiary care children's hospital.
Methods:
Pediatric patients (<18 years) with high-risk OSA (any 1 of: apnea-hypopnea index [AHI] >30, O2 nadir <80% and peak CO2 >60 mm Hg) on overnight PSG from 2019 to 2021 were included. Primary outcomes were major respiratory intervention during the postoperative admission, prolonged hospitalization, and intensive care unit (ICU) stay.
Results:
A total of 307 patients met inclusion criteria. Median age was 6.5 years and 63% were male. Twenty-five (8.1%) required major respiratory intervention and 29 (9.7%) required ICU admission after AT. Major interventions and ICU admissions were significantly associated with neuromuscular disease (P < .01), higher obstructive apnea-hypopnea index (oAHI), higher CO2 peak, and lower O2 nadir. Prolonged admission had similar findings except oAHI was not significantly associated. Younger children were significant more likely to require ICU admission or prolonged admission.
Conclusion:
Increased oAHI and worsening O2 and CO2 parameters on preoperative PSG were associated with postoperative respiratory complications in children with high-risk OSA. Children with neuromuscular disease and age 0 to 2 had higher risk of ICU stay and prolonged hospitalization. Clinicians should recognize the importance of parameters beyond oAHI when anticipating postoperative monitoring.
