Efficacia analgesica di ropivacaina e bupivacaina, dopo chirurgia ortopedica nel cane, additivate all'anestesia generale mediante blocchi loco-regionali degli arti con localizzatore neurale : 159 casi

Aim of this study was to evaluate the analgesic effect of ropivacaine(RPV) and bupivacaine (BPV) used for regional limb blockade, in anaesthetised dogs undergoing orthopaedic procedures localised distally to the scapula or hip. Loco-regional limb blockade was obtained in each case by using nerve locator. A score pain, calculated with a multiparametric pain scale by a random blind operator, was given to every subject. Analgesic effects achieved by using RPV or BPV showed to be equivalent, without statistically significant differences. In this case, since the higher cardiotoxic effect induced by BPV in dogs, RPV seems to be recommended for post-operative analgesia, after orthopaedic surgery by using single nerve blockade.
