Abstract

Background and objective To investigate the effects of the perineural injection of lidocaine or corticosteroids on radicular blood flow during spinalsurgery. Methods After lumbar discectomy, a probe for laser Doppler flowmetry was placed directly on the 4th or 5th lumbar nerve root. Thirty patients undergoing lumbar discectomy were randomly assigned to one of three groups. Each group received one of three protocols for a perineural injection to the nerve root: 1.6 mt 0.9% saline in group A, 1.0 mt 1% lidocaine in group B or 1.6 mt dexamethasone (4 mg) in group C. Measurements included radicular bloodflow, mean arterial pressure, haemoglobin concentration, percutaneous oxygen saturation and end-tidal carbon dioxide tension. Radicular blood flow was measured by laser Doppler flowmetry before the injection and 15 min afterthese injections. The three groups were similar with respect to mean arterial pressure, haemoglobin concentration, percutaneous oxygen saturation andend-tidal carbon dioxide tension. Results Radicular blood flow did not change after the injection in any of the groups. Conclusions The results suggest that the perineural injection of 1% lidocaine or dexamethasone does not affect radicular blood flow during lumbar discectomy.
