Cardiorespiratory/sedative effects of a peptide identified in crotalic venom compared to acepromazine and xylazine in horses
ABSTRACT The purpose of this study was to investigate whether intravenous crotalphine produces significant sedation, as well as physiological changes, in healthy standing horses. Six mares, aged 8 years and weighing 415kg underwent three different treatments in a crossover design: TA (acepromazine: 50μg.kg-1), TC (crotalphine: 0.01μg.kg-1) and TX (xylazine: 1000μg.kg-1), intravenously. At various time points over 60 minutes, physiologic variables were recorded: heart rate, respiratory rate, and rectal temperature. The head height from the ground (HHG) was evaluated in centimeters. Data were analyzed using ANOVA followed by Dunnett’s test or Friedman followed by Dunn’s test, under 5% significance. Heart rate decreased significantly at M5 and M10 compared with Mb in TX (28±7, 26±6 and 40±8 beats/minute-1, respectively; p=0.0004). Respiratory rate and rectal temperature did not differ among groups or time points. The HHG significantly decreased in all groups compared with Mb at various time points (p<0.0001). In conclusion, crotalphine did not produce reliable and durable sedation in healthy standing mares and did not influence cardiorespiratory variables in a clinically relevant manner.
期刊介绍:
Publica artigos originais de pesquisa sobre temas de medicina veterinária, zootecnia, tecnologia e inspeção de produtos de origem animal e áreas afins relacionadas com a produção animal. Atualmente a revista mantém 628 permutas (419 internacionais e 209 nacionais), sendo um verdadeiro suporte para o recebimento de periódicos pela Biblioteca da Escola.
A partir de 1999, a Escola de Veterinária delegou à FEP MVZ Editora o encargo do gerenciamento e edição de todas suas publicações, inclusive do Arquivo, ficando somente com o apoio logístico (instalações, equipamentos, pessoal etc.). O apoio financeiro é exercido pelo CNPq/FINEP e pela própria FEP MVZ.
