Predicting Respiratory Complications for Day Case Paediatric Adenotonsillectomy

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Sleep Medicine

Background:

• Adenotonsillectomy is a common procedure for pediatric obstructive sleep apnoea (OSA).
• Identifying patients at risk for post-operative respiratory complications is crucial for day-case surgery safety.
• Current triaging models require refinement for optimal risk stratification.

Purpose of the Study:

• To evaluate a pre-operative triaging model for pediatric adenotonsillectomy.
• To identify risk factors for early post-operative respiratory complications.
• To propose an evidence-based triaging model for day-case pediatric adenotonsillectomy.

Main Methods:

• Retrospective cohort study of 2953 children (2-12 years) undergoing adenotonsillectomy for OSA.
• Patients were triaged as low-risk or high-risk based on age, comorbidities, and pre-operative oximetry or polysomnography.
• Analysis of pre-operative factors, intra-operative details, and post-operative outcomes.

Main Results:

• Low-risk group (1229 patients) had a 1.5% complication rate with no major events.
• High-risk group (1724 patients) had an 11.7% complication rate, including non-invasive ventilation and ICU admissions.
• Severe OSA (OR 9.5) and recovery room complications (OR 13.6) were significant risk factors for respiratory compromise.

Conclusions:

• Pre-operative oximetry and polysomnography are valuable for triaging pediatric adenotonsillectomy patients.
• These investigations aid in stratifying risk for safe day-case surgery.
• An evidence-based triaging model can improve patient safety.
