Abstract
Local anesthetic effects of trimecaine, lidocaine and bupivacaine have been compared in high axillary brachial plexus blockade in 110 patients operated on the lower limb. The clinical pattern of conductive anesthesia and its efficacy (90 to 95.5%) did not depend on the kind of the anesthetic used. The rate of analgesia development in this technique is determined by physicochemical properties of the drug. Trimecaine effect is of minimum duration (130.0 +/- 1.3 min), while bupivacaine effect is of maximum duration (375.7 +/- 22.7 min). Lidocaine has an intermediate position (161.4 +/- 2.6 min).
