Ketorolac Effects on Post-operative Pain and Lumbar Fusion: a Double Blind Randomized Controlled Trial

Phase 4 Interventional University of Maryland St. Joseph Medical Center · NCT06513208

This study will test whether an IV ketorolac dose after surgery reduces post-operative pain and opioid use for adults having elective one- or two-level posterior lumbar fusion.

What this trial studies

This is a randomized, double-blind, placebo-controlled Phase 4 trial comparing IV ketorolac to placebo in adults undergoing elective one- or two-level posterior instrumented lumbar fusion. Participants aged 18–85 who meet medical criteria will be randomized to receive ketorolac or placebo around the time of surgery and followed through post-operative visits. Pain scores and analgesic (opioid) use will be tracked, and safety measures such as renal function and bleeding will be monitored. Common exclusion criteria include significant renal impairment, recent smoking, revision surgery, active cancer or recent chemotherapy, recent narcotic use, and allergies to NSAIDs or opioids.

Who should consider this trial

Good fit: Adults 18–85 scheduled for elective one- or two-level posterior instrumented lumbar fusion who can consent, speak English, and have no renal failure, recent smoking or chronic opioid use, revision surgery, active cancer treatment, or NSAID/opioid allergies are ideal candidates.

Not a fit: Patients with renal impairment, active or recent smokers, recent or ongoing narcotic use, revision fusion cases, active cancer or recent chemotherapy, or allergies to NSAIDs/opioids are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, patients may have better post-operative pain control and require fewer opioid pain medicines after lumbar fusion.

How similar studies have performed: NSAIDs including ketorolac have been shown to reduce post-operative pain and opioid use in many surgeries, but data specific to lumbar fusion and effects on fusion rates are mixed and not fully settled.
