[Mepivacaine for axillary plexus anesthesia. Comparison of mepivacaine-CO2 and mepivacaine-HCI].
Forty patients scheduled for elective surgery of the hand-forearm region under axillary plexus block received mepivacaine carbonate or mepivacaine hydrochloride (1% solution) in a random fashion. Onset and spread of the resulting anaesthesia were recorded, using the pin-prick test in the area propria of the nervus axillaris, musculocutaneus, radialis, medianus, ulnaris, intercostobrachialis and cutaneus antebrachii medialis. The motor block was assessed by testing the strength of arm flexion (n. musculocutaneus), extension (n. radialis), grip strength of the hand (n. medianus) and lateral abduction of the fingers (n. ulnaris). The results suggest that there is no difference of the effects of the two preparations. In ten patients of each group, blood levels of mepivacaine were determined during 90 min after the injection. The difference between the two groups (the levels after the carbonate being higher during the first 30 min) was significant at 15 min.
