Pain Management: Medication and Surgery Indications
Both medication and surgery are medically indicated for pain management, with the specific approach determined by pain severity, underlying pathology, and patient-specific factors. 1
Medication Management for Pain
First-Line Pharmacological Approach
Multimodal analgesia using non-opioid medications should be the foundation of pain management. 1 This approach combines different drug classes to achieve additive or synergistic pain relief while minimizing individual medication side effects. 1
Non-Opioid Medications (Preferred Initial Therapy)
Acetaminophen should be administered at the beginning of pain therapy as it may be safer than other drugs and reduces opioid requirements when used in multimodal regimens. 1
NSAIDs (including ibuprofen and diclofenac) are strongly recommended when contraindications are absent, as they effectively treat moderate pain and reduce morphine consumption. 1, 2, 3
- Use the lowest effective dose for the shortest duration (typically 400 mg ibuprofen every 4-6 hours, not exceeding 3200 mg daily). 3
- NSAIDs should be used for brief periods only due to cardiovascular and gastrointestinal risks. 2, 3
- Critical pitfall: Never combine NSAIDs with opioids initially, as this increases harm without proportional benefit. 2
COX-2 inhibitors (coxibs) may be considered if there are no contraindications, particularly in patients at higher gastrointestinal bleeding risk. 1
Gabapentinoids (gabapentin, pregabalin) are recommended as components of multimodal analgesia, particularly for neuropathic pain. 1
Opioid Medications (Reserved for Severe Pain)
Opioid usage should be reduced as much as possible and reserved only for moderate-to-severe pain unresponsive to other medications. 1
- Opioids are indicated when non-opioid approaches fail and regional anesthesia is not feasible. 1
- Avoid initial continuous infusion in opioid-naïve patients; start with bolus dosing. 1
- Patient-controlled analgesia (PCA) is recommended for appropriate candidates with adequate cognitive function. 1
- Common opioid options include morphine, fentanyl, oxycodone, and sufentanil, though no single agent shows clear superiority. 1
- For chronic pain, opioids should be used judiciously given the opioid crisis; tramadol may be considered as an alternative in patients with cardiopulmonary compromise. 1
Pain Assessment and Monitoring
Regular pain assessment at standard intervals is mandatory, not just "as needed" or according to pain scales alone. 1 After any pain intervention, reassess for both pain control and adverse reactions at appropriate intervals based on the anticipated effect. 1 When pain worsens significantly, reevaluate for possible complications. 1
Special Populations Requiring Caution
- Obstructive sleep apnea patients: Minimize opioid use to prevent cardiopulmonary complications. 1
- Younger age and female gender are risk factors for acute postoperative pain requiring more aggressive management. 1
- Patients with psychiatric comorbidities, chronic pain, or substance abuse history require specialized pain management approaches. 1
Surgical Interventions for Pain
Indications for Surgical Pain Management
Surgery is indicated for pain when:
- Conservative treatments have failed and pain significantly impacts quality of life. 1
- Structural pathology causes pain that can be corrected surgically (e.g., malignant spinal cord compression, gastric outlet obstruction, hidradenitis suppurativa). 1
- Emergency conditions exist requiring urgent surgical decompression or stabilization. 1
Specific Surgical Scenarios
Malignant Spinal Cord Compression
- Radiotherapy is first-line treatment for the majority of patients, providing back pain relief in 50-58% of cases. 1
- Surgery followed by radiotherapy should be reserved for carefully selected patients with single-level compression and neurological deficits. 1
- Dexamethasone (16 mg/day) should be given immediately when diagnosis is obtained. 1
Gastric Outlet Obstruction
- Endoscopic stent placement is safe and effective for patients with shorter life expectancy. 1
- Gastrojejunostomy is preferable for patients with more prolonged prognosis. 1
- Severe uncontrolled pain after stent placement requires emergent endoscopic stent removal. 1
Hidradenitis Suppurativa
- Surgical excision is reserved for disease uncontrolled by pharmacologic care. 1
- Medical therapy may be continued perioperatively without interruption, as poorly controlled disease poses higher surgical risk than medications. 1
Procedural Pain Management
For temporomandibular disorders and myofascial pain:
- Manual trigger point therapy provides the largest pain reduction and should be initiated immediately. 2
- Supervised jaw exercises with stretching provide 1.5 times the minimally important difference in pain relief. 2
- These non-pharmacological interventions provide superior pain relief compared to NSAIDs alone. 2
Critical Clinical Pitfalls to Avoid
- Never discontinue antiplatelet therapy perioperatively except in specific high-bleeding-risk scenarios (intracranial, spinal canal, posterior eye chamber surgery), as thrombotic risk exceeds bleeding risk. 4
- Do not rely solely on pain scales for assessment; use standardized intervals with comprehensive evaluation. 1
- Avoid prolonged NSAID use beyond brief initial trials due to cardiovascular and gastrointestinal complications. 2, 3
- Do not prescribe opioids for myofascial pain dysfunction due to lack of evidence and significant harm potential. 5
- Never assume pain is solely from one condition in patients with multiple comorbidities; coexisting fibromyalgia may complicate assessment. 6
