Improved postoperative pain control in pediatric adenotonsillectomy with dextromethorphan.

Abstract

A prospective, randomized, double-blinded, placebo-controlled protocol. An academic, tertiary care referral center. Forty randomly selected children, ages 3 to 13 years, scheduled for adenotonsillectomy without other simultaneous procedures. A single, oral dose of dextromethorphan pediatric cough syrup (1 mg/kg) or placebo given 30 minutes before surgery. Total dose requirement of intravenous morphine within a 6-hour postoperative observation period. During routine postoperative observation, significantly fewer patients in the dextromethorphan group required no intravenous morphine compared with the placebo group (P =.03). Of those children requiring morphine, the mean dose requirement was significantly lower in the dextromethorphan group (P =.02). There was no known drug-related morbidity. Dextromethorphan syrup is a safe, non-narcotic medication that significantly reduced the requirement of intravenous morphine after pediatric adenotonsillectomy. Its routine use in this manner is recommended.
