Abstract
Esthesia were randomly allocated to receive 1 mg/kg of either 5% or 2% lidocaine in 7.5% glucose. Patients were evaluated on the first postoperative day by an anesthesiologist who was unaware of the solution administered or the details of the anesthetic procedure. Symptoms suggestive of transient radicular irritation were observed in 8 patients (32%) receiving 5% lidocaine, and in 10 patients (40%) receiving 2% lidocaine (NS). These results confirm our previous findings that transient neurologic symptoms may occur in up to one third of the patients receiving 5% lidocaine, and indicate that a modest reduction in lidocaine concentration does not reduce risk.
