COMPARISON OF LOCAL ANAESTHETIC EFFECTS OF TRAMADOL AND LIDOCAINE FOR SKIN BIOPSY IN EQUINES.

Abstract

This study was aimed at comparing the local anesthetic effect of tramadol and lidocaine for skin biopsy in equines. Eight mature horses underwent skin biopsy after infiltration with either 2.5% tramadol (GT) or 1% lidocaine (GL). The following parameters were evaluated: the onset, duration of block (DB), skin alteration (SA), quality of block (QB), heart rate (HR), respiratory rate (RR) and rectal temperature (T). HR, RR and T were measured before the local blockade and every 15 minutes until the end of the anaesthesia. The onset: immediately after the infiltration of the drugs until sensory blockade. DB: immediately after sensory blockade until reappearance of sensibility. The sensibility test was accomplished every 10 minutes with mechanical nociceptive stimuli. Statistical analysis was done using Tukey
