Pain, PONV, Temperature, and Comfort Interventions
Key Takeaways
- Pain treatment in PACU follows assessment of airway, sedation, respiratory status, procedure, baseline opioid exposure, and complication clues.
- Severe pain out of proportion, new neurovascular deficit, chest pain, or pain with instability should trigger assessment before routine analgesia.
- PONV management starts with airway protection, aspiration prevention, hydration assessment, and ordered antiemetics or nonpharmacologic support.
- Hypothermia and shivering increase oxygen consumption and cardiac workload, especially in older patients or those with limited reserve.
- Comfort interventions are still priority-based: treat physiologic threats first, then use positioning, warmth, reassurance, family support, and multimodal measures.
Pain Is an Assessment, Not Just a Score
A numeric pain rating is useful only when it is paired with procedure, baseline status, sedation, respiratory rate, blood pressure, allergies, blocks, chronic opioid use, and patient communication ability. Use developmentally appropriate tools such as faces scales for many children, behavioral tools for nonverbal patients, and critical-care observation tools when self-report is not possible. Reassess after each intervention.
Before giving more opioid, check airway and ventilation. A patient with shallow respirations, high sedation, or rising carbon dioxide needs respiratory support and an adjusted analgesic plan, not automatic dose escalation. Conversely, a tolerant chronic-opioid patient may need higher or more frequent analgesia plus multimodal adjuncts, regional techniques, or pain-service consultation.
Pain That Signals Trouble
| Pain Pattern | Possible Concern | Priority Response |
|---|---|---|
| Pain out of proportion with passive stretch | Compartment syndrome | Neurovascular check, urgent notification |
| Chest pressure with dyspnea or diaphoresis | Ischemia or embolic issue | ABCs, ECG, escalate |
| Neck pressure after thyroid surgery | Expanding hematoma | Airway readiness, surgeon/anesthesia now |
| New back pain during transfusion | Transfusion reaction | Stop product, saline, notify |
| Severe block-site symptoms with tinnitus | Local anesthetic toxicity | Stop source, call help, prepare lipid protocol |
PONV and Aspiration Prevention
Postoperative nausea and vomiting (PONV) can be a comfort issue, but it can also threaten airway, wounds, hemodynamics, and discharge readiness. First protect the airway: turn the head or position laterally when appropriate, provide suction, withhold oral intake until safe, and assess for aspiration signs. Then use ordered antiemetics, hydration support, reduced opioid exposure when possible, slow position changes, aromatherapy or relaxation measures if appropriate, and reassessment.
Persistent vomiting, abdominal distention, blood in emesis, hypotension, severe headache, or neurologic changes should not be treated as routine PONV. Connect the symptom to the procedure and anesthesia history.
Temperature and Shivering
Temperature is a physiologic vital sign. Hypothermia, often less than 36 C, can delay drug metabolism, worsen coagulopathy, increase wound complications, and trigger shivering. Shivering can markedly increase oxygen demand, which matters in patients with coronary disease, anemia, lung disease, or major blood loss. Apply forced-air warming, warm blankets, warmed fluids if ordered, and ongoing temperature checks.
Hyperthermia has a different urgency. Fever may reflect warming overshoot, infection, transfusion reaction, thyroid storm, serotonin syndrome, or malignant hyperthermia depending on timing and associated findings. A rapidly rising temperature with rigidity, tachycardia, and hypercarbia after trigger exposure is an emergency, not routine fever.
Nonpharmacologic Does Not Mean Optional
Positioning, splinting, ice, elevation when appropriate, guided breathing, reduced stimulation, and family presence can lower distress and drug requirements. Use them deliberately, especially when opioids or sedatives are risky. However, do not let comfort measures delay treatment of airway compromise, bleeding, severe neurovascular pain, or an emergency temperature pattern.
Comfort With Safety
Comfort interventions include splinting, repositioning, ice or heat when appropriate, reducing noise and light, protecting privacy, reuniting selected patients with family, treating pruritus, and relieving urinary retention. CPAN questions test sequencing. If the patient is unstable, stabilize first. If the patient is stable but uncomfortable, choose the intervention that matches the cause and then reassess the response.
