Gastroesophageal reflux as a predictor of complications after adenotonsillectomy in young children

Abstract Objective To examine characteristics of young children with gastroesophageal reflux (GER) who experienced complications within the first 24 h after adenotonsillectomy. Study design Subset analysis of a larger retrospective cohort. Methods A retrospective chart review was performed at a tertiary care children's hospital. Consecutive records of children 3 years old and younger undergoing adenotonsillectomy (AT) over a 5-year period were reviewed. Children with a clinical history of GER were selected for the study. Results 993 children were included in the initial analysis, and GER was found to be a significant independent variable predictive of early complications. 81 children with a history of GER were included in this study and 8 (9.9%) were found to have experienced complications within the first 24 h. Six of the complications were airway-related; two required re-intubation within the first 24 h. All 8 children with complications had symptoms of sleep-disordered breathing and two had documented severe obstructive sleep apnea (AHI 18.6 and 27.2). Seven children had other risk factors for complications after AT. Eighteen (22%) children had a prolonged length of stay (range 2–7 days); additional risk factors were present in these patients as well. Conclusions Knowledge of risk factors for complications following adenotonsillectomy is critical for identifying at-risk patients that may warrant closer post-operative observation. GER has been previously identified as a risk factor for complications in young children. Upon closer analysis, young children with GER who have other known risk factors may be at a further increased risk for airway complications and prolonged hospitalization. Parents of these children can be counseled on the post-operative risks and the possibility of a longer hospitalization.
