Summary
Local infiltration anesthesia was insufficient for pain relief in many patients undergoing percutaneous vertebroplasty (PV). Surgeons often underestimated patient pain levels during the procedure.
Area of Science:
- Pain Management
- Anesthesiology
- Orthopedic Surgery
Background:
- Percutaneous vertebroplasty (PV) pain management lacks consensus.
- Evaluating local infiltration anesthesia as sole pain relief is crucial.
Purpose of the Study:
- To assess the efficacy of local infiltration anesthesia for pain control during PV.
- To compare patient-reported pain with surgeon's pain estimations.
Main Methods:
- 44 patients with symptomatic OVCFs received lidocaine infiltration.
- Pain was assessed using a Visual Analog Scale (VAS) post-procedure.
- Patients identified the most painful procedural moment; surgeons estimated VAS scores.
Main Results:
- Mean VAS score was 5.7; 39% found lidocaine insufficient.
- Needle placement was the most painful moment for 66% of patients.
- Surgeons underestimated patient pain (mean expected VAS 3.3 vs. actual mean 5.7).
Conclusions:
- Local infiltration anesthesia alone is insufficient for substantial pain reduction in many PV patients.
- Surgeons frequently misjudge the severity of patient pain during PV.
