Abstract

We examined whether the concentration of hyperbaric lidocaine affected the regression of motor block when the dose of lidocaine was kept constant at 30 mg. We also examined the spread, duration, and regression of sensory block. Sixty-five patients (ASA physical status I or II), scheduled for elective perineum or lower limb surgery, were enrolled in this study. Patients received spinal anesthesia with 1 mL of 3% lidocaine or 3 mL of 1% lidocaine. Adequate level of block was obtained for surgery in 63 of 65 patients. Whereas the administration of 3 mL of hyperbaric 1% lidocaine solution produced a level of sensory block similar to that produced by the administration of 1 mL of hyperbaric 3% lidocaine solution in spinal anesthesia, the administration of 3 mL of hyperbaric 1% lidocaine solution resulted in shorter times to full motor recovery and to urination and produced less motor block compared with 1 mL of hyperbaric 3% lidocaine solution. Two patients receiving 1% lidocaine and four patients receiving 3% lidocaine required IV ephedrine because of hypotension. Our results showed the clinical advantages of hyperbaric 1% lidocaine spinal anesthesia compared with hyperbaric 3% lidocaine spinal anesthesia for surgery of short duration.
