title: [Effects of volume and concentration of lidocaine on epidural anesthesia].
abstract: We studied 40 patients scheduled for gynecological surgery to evaluate the effects of volume and concentration of lidocaine on epidural anesthesia. We injected lidocaine 300 mg as 1% (30 ml) or 2% (15 ml) through epidural catheter at L 1/2. There was no significant difference in the spread of sensory blockade (cold and pain) and the Bromage scale between the two lidocaine solutions. This result suggests that volume and concentration of lidocaine do not affect the effects of epidural anesthesia.
