Abstract

Abstract: Introduction: Adenotonsillectomy is the first-line treatment for pediatric obstructive sleep apnea (OSA). The postoperative course may be complicated by hypoxia, requiring intervention. Positive pressure respiratory support (PPS ) could be used to bridge the postoperative period and avoid invasive mechanical ventilation; however, the safety of PPS following tonsillectomy has not been established. Objective To review the incidence of complications and risk factors associated with PPS use immediately after tonsillectomy. Methods: A retrospective cohort study between 2015 and 2020 of patients who underwent tonsillectomy and were admitted to the pediatric intensive care unit at a single healthcare system. Results: Seven hundred eighty patients met inclusion criteria, including 101 patients treated with PPS immediately following surgery. A similar number of patients were diagnosed with severe OSA in each group prior to surgery. One patient in the PPS cohort developed pneumomediastinum and pneumothorax. Eleven patients (12%) in the PPS group and 18 patients (2%) in the non-PPS group developed life-threatening complications, defined as pneumothorax/pneumomediastinum, re-intubation, post-tonsillectomy bleeding that required surgical intervention, pulmonary edema and death, and all occurred in patients who had not used PPS at baseline. Regression analysis identified body mass index, surgical technique, and PPS use to be associated with increased odds of life-threatening complications. Conclusion: Our study suggests that PPS is generally safe to use. New-onset PPS is associated with increased odds of life-threatening complications, likely reflecting a severe post-surgical clinical course.
