The purpose of this study was to evaluate the quality of analgesia provided by morphine and meperidine in the cats presenting traumatic process and submitted to osteosynthesis, Eighteen animals were divided into two groups. Animals from group I were premedicated with acepromazine (0.2mg/kg) and meperidine (4.0mg/kg) and were induced with administration of ketamine (3.0mg/kg) and midazolan (0.3mg/kg). Anesthesia was mantained using halothane and 100 % oxigen. Group II was premedicated with acepromazine (0.2mg/kg)and morphine (0.2mg/kg) and then submited to the same protocol proposed to group I. Heart and respiratory rate, systolic arterial blood pressure, oxihemoglobin satuation, carbon dioxide pressures, inspired and end-tidal concetrations of halothane were evaluated at pre, trans and pos surgery for statistical analysis, concluding that morfine and meperidine presented sastifactory analgesia.
