Popis: Objectives Adenoidectomy and/or tonsillectomy are commonly performed in tertiary pediatric hospitals for the management of obstructive sleep apnea, often in children with significant comorbidities. This study examines the peri-operative course of a large series of complex patients undergoing such surgery at a major pediatric centre, reporting particularly cases of respiratory compromise requiring intensive care admission, both electively and unplanned. Methods This study was conducted by the pediatric ENT department at Great Ormond Street Hospital. All children undergoing adenoidectomy and/or tonsillectomy from July 2003 to December 2010 were included in this study. This involved a retrospective review of the case notes and hospital databases, with particular emphasis on those children requiring admission to the pediatric intensive care unit. Results A total of 1735 consecutive admissions for adenoidectomy and/or tonsillectomy (1627 individual patients aged 4–197 months, median 46 months) were included between 2003 and 2010 (998 adenotonsillectomies, 182 tonsillectomies and 555 adenoidectomies). In this group, 999/1627 patients (61.4%) had a diagnosis of sleep disordered breathing or sleep apnea, including 258 who had polysomnography. 407/1627 (25.0%) had no specific comorbidities which were felt likely to influence their surgical outcome. Established high risk factors included age less than 24 months (292), Down syndrome (99), neuromuscular problems (314), craniofacial abnormalities (94), storage diseases (23), morbid obesity (20), cardiovascular disease (133), respiratory disease (261), hemoglobinopathy (76) and coagulophathy (34). 300/1735 admissions were day cases and 1082/1735 were observed for one night. 353/1735 required more than one night in hospital (294 for two to three nights). 7/1735 had primary hemorrhage necessitating return to the operating room, all after tonsillectomy. 41/1735 (38 with major comorbidities) required peri-operative intensive care admission, mostly for respiratory support. Of these, 7 were admitted pre-operatively to intensive care, and 17 were planned post-operative transfers. Only 17/1735 required unanticipated post-operative admission to intensive care. Odds ratio analysis suggested a significantly higher chance of PICU admission in children with particular comorbidities (Down Syndrome, cardiac disease, obesity, cerebral palsy, craniofacial anomalies, mucopolysaccharidoses and hemoglobinopathy) when compared to children without comorbidities. Adenotonsillectomy was associated with a higher risk of PICU admission than adenoidectomy alone, but patient age less than 24 months was not associated with significantly higher rates of PICU admission. There were no peri-operative mortalities in this cohort. Conclusions The peri-operative course was largely uneventful for the majority of children undergoing surgery during this period, particularly given the high prevalence of sleep apnea and other risk factors in this cohort. Major complications were uncommon, with 2.4% of these selected, typically high risk cases requiring peri-operative intensive care admission. Importantly, only 1% of all admissions required unanticipated transfer to intensive care. This has informed changes in peri-operative management in this unit, with implications for other pediatric tertiary referral centres.
