title: A meta-analysis of dexamethasone use with tonsillectomy.
abstract: OBJECTIVE
  To determine the quantitative impact of intravenous dexamethasone on recovery after tonsillectomy using established principles for meta-analysis.
  
  
  METHODS
  Double-blind randomized-control trials in which subjects were treated identically except for the presence or absence of perioperative intravenous dexamethasone. Six articles met inclusion criteria. Two investigators extracted data regarding postoperative emesis and return to a soft/regular diet.
  
  
  RESULTS
  Pooled analysis using a random effects model revealed a 27% decrease (P<0.00001) in postoperative emesis attributable to dexamethasone (95% CI, 12% to 42%). Dexamethasone increased the tolerance of a soft/regular diet at 24 hours by 22% (P< 0.001), but studies were heterogenous with low precision (95% CI, 1% to 44%).
  
  
  CONCLUSIONS
  To prevent emesis in 1 child after tonsillectomy, approximately 4 children must receive perioperative dexamethasone. An additional benefit is earlier tolerance of a soft/regular diet, but low precision and heterogeneity among studies preclude definitive conclusions.
  
  
  CONCLUSIONS
  Perioperative dexamethasone administration had a positive impact on recovery from tonsillectomy.
