Study Details

Brief summary:

The multicenter PRECISE Analgesia (Prospective Randomized Evaluation of Analgesia for Idiopathic Scoliosis Spine Fusion Elective Surgery in Children) trials will a) implement and investigate the efficacy and safety of multidose methadone-based standardized enhanced recovery after surgery (ERAS) protocol, and b) develop personalized ERAS protocols including precision methadone and oxycodone dosing and c) personalized analgesia for the safe and effective opioid-sparing management of surgical pain after posterior spine fusion (PSF) in children.

Interventions and Outcome Measures

Arms

experimental: Methadone-Based ERAS Group

The methadone-based standardized analgesia intervention arm will include standardized perioperative care and analgesia, including intraoperative intravenous methadone (1st dose: 0.1 mg/kg up to a maximum of 5 mg before incision; 2nd dose: 0.1 mg/kg up to a maximum of 5 mg administered 4 hours after the 1st dose) and postoperatively, up to 4 additional IV or oral doses of methadone (0.1 mg/kg up to a maximum of 5 mg) every 12 hours before discharge as part of standardized multimodal analgesia in the hospital setting.

active comparator: Non-Methadone-Based Group

The comparator standard-of-care non-methadone-based analgesia arm will include standard opioid analgesia protocol without intra- and post-operative methadone per the current site standards.

Interventions

Methadone based ERAS

Methadone intervention includes intraoperative intravenous methadone (1st dose: 0.1 mg/kg up to a maximum of 5 mg before incision; 2nd dose: 0.1 mg/kg up to a maximum of 5 mg administered 4 hours after the 1st dose) and postoperatively, up to 4 additional IV or oral doses of methadone (0.1 mg/kg up to a maximum of 5 mg) every 12 hours before discharge as part of standardized multimodal analgesia in the hospital setting.

Non-methadone based group

Non-methadone intervention includes standard opioid analgesia protocol without intra- and post-operative methadone per the current site standards. Postoperative pain medication is recommended when reported pain level is considered moderate or higher (≥4 on NRS and FLACC).

Primary outcome measure

  • Average postoperative pain scores [ Time Frame: Postoperative 48 hours ]
  • Total postoperative opioid use [ Time Frame: Postoperative 48 hours ]
