ObjectiveSystematically review the published literature comparing the presence of clinical features (age, BMI, co-morbidities, etc.) versus polysomnogram (PSG) results in the prediction of major post-operative respiratory complications following pediatric adenotonsillectomy (T/A) for the treatment of Obstructive Sleep Apnea Syndrome (OSAS).MethodsA systematic review of the PUBMED and EMBASE databases was performed to identify studies containing both clinical and PSG data predicting major post-operative respiratory complications following T/A. Inclusion criteria included English language and extractable data. Major respiratory complications were defined as events that required significant intervention (intubation, CPAP,etc.) and/or altered patient disposition. Random effect modeling was performed and study quality was assessed using the Newcastle-Ottawa Scale.ResultsTwenty-two studies met the inclusion criteria with a median sample size of 157 (range 26–1735) and published between 1992 and 2015. The most common study design was a case series. Most studies included multiple patients at high risk for respiratory complications (Syndromic, obese, etc.). The summary estimate of the major respiratory complication rate following T/A was only 5.8% (95% CI = 4.2–7.4%, p < 0.001, I² = 99%). For studies with extractable data, 102 of 112 patients (91.1%) with a post-operative respiratory complication had a clearly identifiable clinical risk factor, the remainder (8.9%) had only moderate or severe OSAS on PSG and no other predictor.ConclusionThe major respiratory complication rate following pediatric T/A for OSAS is low even amongst series of high risk patients. The majority of the published literature report that readily identified clinical factors predict the large majority of post-operative respiratory complications following T/A.
