Brief Summary:
The purpose of this study is to look at a standardized methadone-based enhanced recovery after surgery protocol following pediatric cardiac surgery. This study will consist of randomly assigning children to receive the methadone-based recovery procedures or to receive current standard of care recovery procedures. Randomly assigning means that there is a 50/50 chance, like a coin flip, of being assigned to either research group.
Detailed Description:
Specific Aims Aim 1. Conduct a randomized clinical trial in cardiac surgery (CS) to compare acute pain relief, opioid-sparing efficacy, and safety of standardized perioperative multidose methadone-based enhanced recovery after surgery (ERAS) vs. standard-of-care non-methadone-based analgesia.
Aim 2. Develop precision methadone dosing based on age, CYP2B6 and ORM1 variants, and alpha acid glycoprotein (AAG) levels, cardio-pulmonary bypass (CPB) related dilution.
Aim 3. Identify patient profiles that predict benefits from the assigned analgesia protocol to optimize clinical outcomes. Personalized risk prediction models will be developed and validated including genetic variants (i.e., CYP2B6, CYP2D6, ABCB1, OPRM1, and FAAH), and psychological and clinical factors to predict benefit with the assigned treatments (methadone or non-methadone) for pre-specified clinical endpoints (i.e., lower acute surgical pain, respiratory depression \[RD\], postoperative nausea and vomiting \[PONV\], opioid dependence \[OD\], and chronic postsurgical pain \[CPSP\]) in cardiac surgery.
Overall Impact Investigators will develop actionable evidence for the efficacy of standardized, multidose, methadone-based ERAS protocols and will harness genetic, clinical, and psychological factors contributing to variability in methadone and oxycodone PK, acute surgical pain, transition to CPSP, opioid-induced PONV, RD, and dependence to develop personalized analgesia strategy and dosing for children undergoing cardiac surgery. Implementation of evidence-based standardized methadone-based ERAS pain management and individualized risk prediction will maximize acute surgical pain relief while minimizing opioid use and AEs in millions of children.
Hypothesis The central hypothesis is that a standardized, multidose, methadone-based ERAS protocol will reduce acute surgical pain, overall opioid use, RD, PONV and CPSP compared with standard-of-care short-acting opioid-based analgesia in children undergoing cardiac surgery. The long-term goal is to proactively improve the safety and efficacy of surgical pain control while reducing opioid AEs and the opioid epidemic burden in all children undergoing inpatient surgeries. Further, we hypothesize that age, CYP2B6 and ORM1 variants, AAG levels, and CPB-related dilution will explain methadone's PK variability and dose adjustments that correlate with optimal clinical outcomes, and that patient profiles based on genetic, psychological, and that clinical factors will predict benefits from the assigned analgesia protocol to optimize clinical outcomes.
