Preoperative Oral Dextromethorphan Does Not Reduce Pain or Analgesic Consumption in Children After Adenotonsillectomy

Abstract

Premedication with dextromethorphan 0.5 or 1.0 mg/kg p.o. does not improve postoperative analgesia in school-aged children who receive preemptive morphine 0.075 mg/kg i.v. and acetaminophen 25-35 mg/kg p.r. during nitrous oxide and desflurane anesthesia for adenotonsillectomy.
