Pediatric obstructive sleep apnea: a prospective observational study of respiratory events in the immediate recovery period after adenotonsillectomy
Authors' conclusion
Respiratory volume monitoring in the immediate postoperative period after pediatric high-risk adenotonsillectomy identifies impaired ventilation more frequently than is clinically apparent.
Study context
- Population
- High-risk children having adenotonsillectomy for obstructive sleep apnea
- Participants
- 60 children
- Outcome
- Respiratory depression and airway obstruction in the PACU measured by noninvasive respiratory volume monitor (RVM): episodes of predicted minute ventilation <40% for ≥2 min
Methodological detailsobservational
- Observational
Main finding
As reported in the abstract
≥1 episode of PACU respiratory depression or airway obstruction (RVM)
Children with ≥1 episode of post-anesthesia care unit (PACU) respiratory depression or airway obstruction measured by respiratory volume monitor (RVM)

Observational data: associations, not effects.
Further findings
Clinically apparent respiratory events in PACU
- Children with clinically apparent respiratory events
- 21 (35%)
Factors associated with increased episodes of respiratory depression and airway obstruction (Poisson regression)
- BMI Z-score less than −1: estimate
- 3.91 (95% CI 1.49-10.23)
- BMI Z-score 1-2: estimate
- 2.04 (95% CI 1.20-3.48)
- Two or more comorbidities: estimate
- 1.96 (95% CI 1.11-3.46)
