the average duration ( minutes +/- s.d . ) of analgesia produced by the respective injectates was as follows : lidocaine 0.5 % -42+/-12 lidocaine 1.0 % -47+/-10 mepivacaine 0.5 % -58+/-13 mepivacaine 1.0 % -78+/-23 procaine 0.5 % -0+/-0 procaine 1.0 % -34+/-10 procaine 1.5 % -46+/-13 2-chloroprocaine 1.5 % -38+/-9 bupivacaine 0.5 % -100+/-40 etidocaine 1.0 % -59+/-25 tetracaine 0.2 % -0+/-0 tetracaine 0.3 % -0+/-0 comparison with other animal models used to evaluate conduction block indicates that this technique affords an improved , standardized and reliable experimental guide to the clinical analgesic properties of local anaesthetic agents .
