Post-op Pain in Remission from Opioid Use Disorder: A Multimodal Judgment Call
Ms. T, 41, is post-op day 1 after a laparoscopic cholecystectomy. She rates pain 8/10, is guarding, has not ambulated or slept, and reports nausea 3/10. HR 104, BP 138/84, RR 22 and shallow. She has three years in remission from opioid use disorder and takes buprenorphine-naloxone 8/2 mg daily; she tells you she wants "nothing addictive." Orders: hydromorphone 0.5 mg IV q2h PRN, ketorolac 15 mg IV q6h, ondansetron 4 mg IV q6h PRN. She has had two doses of hydromorphone with minimal relief. You have six other patients and a 30-minute window before shift handoff.
1. Prioritize your assessment. What data would change your plan, and what would make you escalate immediately?

Rule out the things that are not "just pain" first
- HR 104, RR 22, shallow breathing, guarding: these are also compatible with splinting from pain, hypovolemia, atelectasis, or early sepsis. Check temperature, SpO2, lung sounds at bases, abdominal exam (rigidity, distension), urine output, and incision sites before titrating more opioid.
- Assess pain with a function-based question: "What could you do at this pain level?" rather than only the number. A score that cannot be moved by 3 mg of opioid equivalent is either a different pain mechanism (visceral spasm, gas, incisional, positioning) or inadequate analgesia from subtherapeutic dosing.
Escalate immediately if: rigid or distended abdomen, fever, falling urine output, SpO2 dropping with shallow breathing, or rising sedation with a falling respiratory rate. Those findings convert this from a pain-management problem into a deterioration problem, and the hydromorphone PRN is then the wrong lever.
Specifically relevant to her history
Buprenorphine has high mu-receptor affinity and can blunt the effect of full agonists. Two doses of hydromorphone 0.5 mg is a low dose to begin with, so "minimal relief" may be a dosing/affinity issue rather than opioid tolerance or drug-seeking. That distinction must be made with the prescriber, not inferred at the bedside.
2. Design a multimodal plan for the next 12 hours that honors her request to avoid "addictive" medication while actually controlling her pain. Justify each element.

Layer mechanisms rather than escalating one drug
| Element | Rationale |
|---|---|
| Scheduled ketorolac around the clock while renal function and bleeding risk allow | Addresses inflammatory/visceral component; reduces opioid need |
| Scheduled acetaminophen if not contraindicated | Different mechanism, no dependence risk |
| Ondansetron before ambulation and meals | Untreated nausea makes pain feel worse and blocks mobility |
| Splinting pillow, repositioning, early ambulation with assistance | Gas pain after laparoscopy responds to movement, not opioid |
| Warm blanket, slow breathing, guided imagery or music of her choosing | Autonomic down-regulation; she retains control, which matters given her history |
| Sleep protection: cluster vitals and meds, dim lights 2200–0600 | Sleep deprivation amplifies pain perception |
Reframe the opioid conversation
Her "nothing addictive" is a legitimate goal, not an obstacle. Say: "Your goal is to leave here without your recovery at risk. That means we use the smallest opioid dose that lets you walk and breathe deeply, and we stop it as soon as the other approaches carry the load." Agonist-antagonist or partial-agonist strategies and the decision about continuing buprenorphine through the perioperative period are prescriber and, ideally, addiction-medicine decisions-your role is to surface the question and get it answered today, not to improvise a buprenorphine plan.
Document the plan's stopping rules so the next shift does not default to PRN-only rescue.
3. Twelve hours later she is ambulating, pain 3/10, but she asks you not to put "drug seeker" in her chart and requests no opioids at discharge. How do you evaluate the outcome and respond?
Read the worked answer
Evaluate against function, not just the number
Success criteria: ambulating, deep-breathing/coughing effectively, sleeping, tolerating diet, pain ≤4/10 with activity, opioid doses trending down, no sedation or respiratory depression. By those criteria the plan worked-name that explicitly in handoff so the improvement is not re-attributed to her history.
Responding to her request
- Tell her the truth about documentation: you cannot purge the record, but you can and will document accurately and without stigmatizing language. Then do it: "reports three years in recovery from opioid use disorder; declined opioids at discharge; multimodal plan effective" is accurate and clinically useful. "Drug-seeking" is neither.
- Flag that her history is medically relevant to future analgesia and to safe prescribing-so the accurate note protects her. Explain this rather than simply agreeing.
- Confirm the discharge plan: non-opioid regimen, bowel regimen, nausea plan, wound care, and a clear pathway to reach the surgical team. Ask whether she wants her buprenorphine prescriber or recovery support notified-offer, do not impose.
Judgment anchor: a holistic plan is not the one that uses the fewest drugs. It is the one that meets the patient's stated goal (protecting recovery) and the physiologic goal (recovery from surgery) at the same time, with the reasoning written down so the next clinician inherits the rationale rather than the label.
