ABSTRACT
The use of sedation protocols to assist in the restraint of cats to perform blood collections is of great importance, but the use of some drugs can alter the results and interpretation. Moreover, the physical restraint may generate intense stress, especially in animals of the feline species, which may also interfere with the results. This study aimed to evaluate examinations of clinical biochemistry in the use of physical restraint and chemistry in cats subjected to two sedation protocols. We used 50 cats, 26 females and 24 males, of mixed-breed, who underwent physical restraint and immediately after underwent two sedation protocols, DB (dexmedetomidine 5μg / kg and 0.3mg butorphanol / kg) and DBC (dexmedetomidine 5μg / kg butorphanol 0.3mg / kg ketamine and 3mg / kg), applied intramuscularly. Blood samples were taken after physical restraint and then after the use of one of the sedation protocols. The following parameters were evaluated: urea, creatinine, alanine aminotransferase (ALT), alkaline phosphatase (ALP), total serum protein (TP), albumin, globulin, cholesterol, triglycerides, calcium, magnesium and chloride in serum samples, and lactate and glucose in fluoride plasma samples. Statistical difference was found between groups for albumin, triglycerides, TP and cholesterol with higher values being found in the DBC group. A statistical difference between moments was found for cholesterol, and ALP with higher values in physical restraint only in the DBC group. Glucose had greater values after sedation for both groups. The study revealed that the use of these protocols implies restrictions on some biochemical parameters studied here, and that their interpretations should be evaluated carefully.
