A Randomized, Double-blind, Controlled, Multi-site Study of the Pharmacokinetics and Pharmacodynamics of Methadone vs. Morphine During Mechanical Ventilation Following Cardiac Surgery in Neonates, Infants and Children
In Brief
A Phase 2 clinical trial evaluating Methadone and Morphine for Pain. Completed, enrolled 47 participants across 3 sites.
Detailed Summary
Study Population: Neonates, infants and children from birth to 5 years of age undergoing cardiac surgery with CPB. The use of methadone to provide analgesia may be increasing due to advantages compared to other commonly used opioid analgesic drugs. While efficacy of methadone has been reported in adults, there is a paucity of information in neonates and infants. In the latter population, fentanyl and morphine are most commonly used for opioid analgesia following major surgery, while methadone is frequently used for weaning of opioid dependent and tolerant patients, in spite of the paucity of knowledge of methadone pharmacology in this population. There are several clinical problems associated with fentanyl and morphine, and methadone may offer superior efficacy with fewer side effects than these agents. We propose to study the pharmacokinetics (PK) and pharmacodynamics (PD) of methadone in neonates and infants in the intensive care unit following cardiac surgery.

Interventions
0.2 mg/kg (IV) for the Initial Loading Dose; followed by PRN ("as needed") doses (given by the ICU Nurses) starting at 0.035 mg/kg (IV) every 30 minutes, for postoperative pain. The PRN dose of methadone may be increased by the ICU doctors until the dose is adequate to relieve the patient's pain.
