Summary

Three arm randomized controlled trial to evaluate the efficacy of a single dose of intraoperative methadone in reducing post-operative pain and opioid consumption in adolescents undergoing posterior spinal fusion. Our secondary goal is to determine the pharmacokinetics of IV methadone in children (0. 4 and 0. 5 mg/kg).

Clinical Details

Official title: Methadone in Pediatric Anesthesia II

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Morphine consumption

Pain scores

Secondary outcome: Methadone clearance

Detailed description: Randomized, controlled, modified dose-escalation design. Patients receive standard monitoring for anesthesia and postoperative care. Surgical and anesthesia (except for opioid use) care are not altered for study purposes. All patients are induced by propofol and muscle relaxants. In the first cohort (n=30 evaluable), subjects are randomized 1: 2 to either control (standard intraop opioid at anesthesiologists' discretion) or methadone HCl (0. 4 mg/kg ideal body weight, IBW). In the second cohort (n=30 evaluable), subjects are randomized 1: 2 to either control (standard intraop opioid) or methadone HCl (0. 5 mg/kg ideal body weight, IBW). Subjects in the study groups will receive methadone (IV bolus, after induction of anesthesia) as their primary intraoperative opioid, rather than leaving the choice of intraoperative opioid to the anesthesiologist. Intraoperative breakthrough pain will be treated at the discretion of the anesthesiologist with fentanyl. In the control groups, intraoperative opioid administration will be left at the discretion of the anesthesia providers. Patient controlled analgesia as prescribed by the clinical team, using hydromorphone or morphine, will be used to treat postoperative pain relief.
