[Clinical and toxicologic study of axillary plexus block with prilocaine or mepivacaine]. 1987

M Tryba, and H Kurth, and M Zenz

A prospective controlled double-blind study was designed to compare the efficacy and the toxicity of mepivacaine and prilocaine for the axillary blockade of the brachial plexus. Twenty patients in each group received 40 ml of either 1.5% mepivacaine or 1.5% prilocaine. The sensory and the motor blockade achieved in both groups were comparable. The mean plasma levels attained following mepivacaine were significantly higher than those attained after prilocaine (peak-plasma level (mean +/- SD): 2.02 +/- 0.28 micrograms/ml vs 5.37 +/- 1.83 micrograms/ml). In four patients of the mepivacaine group, the plasma levels entered the toxic range. While no methemoglobinemia could be detected following mepivacaine, four of the patients receiving prilocaine developed methemoglobinemia with a maximum level of 10%. No complications due to methemoglobinemia were observed in any of the patients. Because of its significantly lower toxic potential, prilocaine seems to be the better local anaesthetic for axillary blockade of the brachial plexus.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008619	Mepivacaine	A local anesthetic that is chemically related to BUPIVACAINE but pharmacologically related to LIDOCAINE. It is indicated for infiltration, nerve block, and epidural anesthesia. Mepivacaine is effective topically only in large doses and therefore should not be used by this route.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic
