Comparison of alpha-2-adrenoreceptors in the epidural anesthesia sacrococcigea of cats undergoing ovariohysterectomy

Abstract

The research was carried out at the Veterinary Hospital, the Department of Veterinary Medicine of Rural Federal University of Pernambuco, where they were used 15 cats undergoing ovariosalpingohisterectomy, participated and aged between one and three years, with weight that ranged between three and four pounds, divided into three groups, submitted to ovariosalpingohisterectomy. The animals were pre-medicated with acepromazine 2%, 0.05 mg/kg. The Ketamine hydrochloride 50 mg/ml, 10 mg/kg and diazepam 5 mg/ml, 0.5 mg/kg, were used for anesthetic induction and maintenance was performed using the ketamine hydrochloride at a dose of 4 mg/kg. Then, they were subjected to epidural anesthesia the sacrococcygeal using only clonidine in dose of 20 μg/kg or xylazine at the dose 2 mg/kg or saline (placebo) 1 ml/3.5-kg. The animals were assessed in relation to hemodynamic parameters, respiratory and body temperature, in addition to the evaluation of the analgesic potential and intensity was reached from the measurement glucose, lactate and cortisol levels, since the pre-anesthetic until the end of the surgery.
