58-year-old man with severe pain after colectomy
A 58-year-old man is on hospital day 2 after an open colectomy for colon cancer. He has chronic lumbar pain treated at home with oxycodone 20 mg every 6 hours and takes gabapentin. Since surgery, he has received intermittent IV morphine for severe incisional pain but now reports 9/10 pain and cannot participate in incentive spirometry or physical therapy. He is afebrile, blood pressure is 148/86 mm Hg, heart rate is 96/min, respiratory rate is 14/min, and oxygen saturation is 96% on 2 L nasal oxygen. He is awake, answers appropriately, and has no myoclonus. Creatinine is 0.9 mg/dL. Which of the following is the most appropriate next step in management?

Explanation
Clinical Pearl:
Hospitalized patients who are already opioid tolerant should not be managed with sporadic as-needed doses alone after major surgery. Continue or replace their baseline opioid requirement, add short-acting medication for breakthrough pain, and pair this with bowel prophylaxis and monitoring for oversedation.
Explanation:
This patient has uncontrolled postoperative pain in the setting of chronic outpatient opioid use, making him opioid tolerant and unlikely to be adequately treated with intermittent as-needed doses alone. Current inpatient pain guidance supports maintaining baseline opioid exposure, often with scheduled dosing or an equivalent long-acting or around-the-clock regimen, while adding short-acting opioid for breakthrough pain and using multimodal adjuncts when appropriate. A bowel regimen and regular sedation and respiratory assessment are essential because opioid safety depends on monitoring, not on undertreating pain. Ketorolac alone is inadequate after major abdominal surgery in an opioid-tolerant patient, and nothing here suggests opioid-induced hyperalgesia. Continuing the same as-needed morphine has already failed, benzodiazepines increase risk of respiratory depression and delirium, and low-flow oxygen use without sedation or hypoventilation is not a reason to withhold analgesia. Effective pain control here also improves pulmonary hygiene and early mobilization.
