Which analgesic plan is appropriate after scoliosis surgery?

• A. Morphine 2 mg IV every 4 hours PRN
• B. Ibuprofen 3 times daily
• C. Acetaminophen 15 mg/kg IV every 4 hours PRN
• D. Oxycodone 5 mg IV every 4 hours PRN

Answer: (A)

Effective postoperative pain control after scoliosis surgery in children hinges on providing potent, titratable analgesia that allows deep breathing and early mobilization. IV morphine is a strong, easily titratable opioid that can be given PRN to match the patient’s pain level, ensuring adequate relief while enabling the child to breathe deeply, cough, and participate in early rehabilitation. This approach aligns with the need for reliable analgesia in the immediate post-op period and allows careful monitoring of respiratory status.

Ibuprofen, an NSAID, is less favored right after major spine surgery because NSAIDs can affect platelet function and hemostasis, increasing bleeding risk, and there is concern about potential effects on bone healing and fusion—making it less appropriate as the primary plan in the immediate post-op period.

Acetaminophen alone provides less intense analgesia and is best used as part of a multimodal approach rather than as the sole plan for major spine surgery.

Oxycodone can be effective, but IV oxycodone is less commonly used as the standard initial plan in this context, and the familiar, titratable control with IV morphine commonly fits the immediate post-op needs.
