Influência de cinco protocolos anestésicos sobre o hemograma de coelhos (Oryctolagus cuniculus familiaris)

Abstract

The anesthetic techniques have been evolving significantly providing comfort, humanity and analgesia to the animals in surgical and outpatient procedures. Local action bupivacaine hydrochloride is often used for rapid procedures involving small areas, and ketamine hydrochloride, which in addition to cause sedation in the animal, also has the utility for chemical containment. They have the ability and property to be associated during a procedure to get a sum of their action or to decrease unnecessary doses. Thirty adult rabbits were divided into five groups (GR) of equal numbers (n = 6), to analyze the influence of five anesthetic protocols on the hemogram, being GR1 - ketamine 20mg / kg, IM; GR2 - bupivacaine minimum dose, IM; GR3 - bupivacaine maximum non-lethal dose, IM; GR4 ketamine 20mg / kg, IM + bupivacaine minimal epidural lumbosacral dose; GR5 - ketamine 20mg / kg, IM + bupivacaine maximum dose non-lethal epidural lumbosacral. The blood of the animals was collected before performing the anesthesia, moment zero (M0) and after 10 (M10), 30 (M30) and 50 (M50) minutes of the accomplishment of each protocol. Significant reductions in red blood cells, hemoglobin, hematocrit, lymphocytes and total leukocytes were observed in both, the groups and at the time of collection, suggesting that anesthetic agents can generate changes in blood tissue.
