Most clinical units admit paediatric obstructive sleep apnoea (OSA) patients to high dependency unit (HDU) following adenotonsillectomy.
We aim to assess the necessity of HDU admissions for paediatric OSA patients following adenotonsillectomy.
A retrospective cohort study was performed for paediatric OSA patients who underwent adenotonsillectomy between 2010 to 2014.
285 patients were included in the study. 64 out of 285 (22.5%) patients suffered post-operative morbidity, which were all respiratory adverse events (RAE). Amongst these patients, 56 out of 64 required interventions. However, majority of these patients (48/64) required simple interventions. Only a minority (8/64) received interventions for severe RAE. Multivariate analysis shows that patients with perioperative anaesthetic events and high BMI are more likely to develop post-operative RAE.
Our results suggest that routine HDU admission is not necessary for paediatric OSA patients undergoing adenotonsillectomy. Selective HDU admission is advocated for at-risk patients.
