Management of Postoperative Lumbar Radicular Pain

First-Line Pharmacological Management

The American College of Surgeons recommends administering NSAIDs and acetaminophen preemptively and continuing throughout the perioperative period as the foundation of pain management 1, 2
Combination therapy with both NSAIDs and acetaminophen provides superior analgesia and reduces opioid requirements, according to the World Journal of Emergency Surgery 2
COX-2 inhibitors, such as celecoxib, can be considered as an alternative to traditional NSAIDs, especially in patients with bleeding risk, as suggested by the World of Neurosurgery 3, 4
Short-term use of NSAIDs appears safe for patients who have undergone spinal fusion, with a duration of less than 2 weeks, according to the World of Neurosurgery 3

Gabapentinoids, such as pregabalin and gabapentin, significantly reduce postoperative pain scores, opioid consumption, and improve long-term functional outcomes when administered preoperatively and continued postoperatively, as recommended by the World of Neurosurgery 3
Dexamethasone can be considered as part of the multimodal approach to reduce inflammation and pain, according to the World Journal of Emergency Surgery and the World of Neurosurgery 1, 4

Local anesthetic wound infiltration with bupivacaine can provide immediate postoperative pain relief, as suggested by the World of Neurosurgery 4
Liposomal formulations of bupivacaine may provide extended relief for up to 96 hours with fewer adverse effects, according to the World of Neurosurgery 4
Conventional or thermal radiofrequency ablation should not be routinely used for the treatment of lumbar radicular pain following surgery, as recommended by the American Society of Anesthesiologists 5

Opioids should be used judiciously and for the shortest duration possible, no more than 7 days, to avoid complications such as respiratory depression, somnolence, urinary retention, and nausea, as recommended by the World Journal of Emergency Surgery and the World of Neurosurgery 1, 4

Regular assessment of pain scores using validated tools, such as the Visual Analog Scale, is essential to evaluate treatment response and guide adjustments, according to the World Journal of Emergency Surgery 1
Follow-up evaluation should assess for persistent symptoms beyond expected duration and functional improvement, as suggested by the World Journal of Emergency Surgery and the Praxis Medical Insights 2

Overreliance on opioids can lead to respiratory depression, nausea, vomiting, and delayed mobilization, as warned by the World Journal of Emergency Surgery and the World of Neurosurgery 1, 4
Up to 75% of people entering treatment for heroin addiction report that their first opioids were prescription drugs, highlighting the importance of judicious opioid prescribing, according to the World of Neurosurgery 4
