Use of the glyceryl guaiacolate alone and associated with levomepromazine and benzodiazepines in gelding of horses

The present paper is aimed to verify the use of glyceryl guaiacolate alone (G1) and associated with levomepromazine and benzodiazepines, of which the flunitrazepam (G2) and midazolam (G3) are used in (10) ten horses for each group, submitted for gelding. The quality of induction and recumbency as well as analgesia was better in the groups that realized the association of glyceryl guaiacolate with levomepromazine and benzodiazepines (G2 and G3), but the recuperation (standing position) of the latter was double of the first one (G1) and for about 60 minutes. There was no significative alteration of the temperature only with the glyceryl guaiacolate group, but there was a tendency of reduction of the temperature in the groups that received the association of the glyceryl guaiacolate with levomepromazine and benzodiazepines. The drugs adninistration in the three groups was followed by tachycardia in the first moments, with normalization in the end. On the other hand was observed bradypnoea and the glyceryl guaiacolate group were distinguished by bigger values of respiratory rate than the other groups. The three anaesthetic procedures showed to be satisfactory, due to the stability of the physiologic parameters and smooth induction and recuperation, while the association of levomepromazine and benzodiazepine with glyceryl guiacolate made recumbency more effective, as well as a bigger muscle relaxation, sedation and analgesia. Visou-se averiguar a utilização do éter gliceril guaiacol isoladamente (G1) ou associado à levomepromazina e benzodiazepínicos, empregando-se o flunitrazepan (G2) e o midazolam (G3) em 10 eqüinos para cada grupo, submetidos à orquiectomia bilateral. Observou-se que a qualidade de indução e decúbito, bem como a analgesia, foram superiores nos grupos em que se realizou a associação de éter gliceril guaiacol com levomepromazina e benzodiazepínicos (G2 e G3), porém, o período de recuperação (estação) destes últimos foi o dobro em relação ao grupo do éter gliceril guaiacol usado isoladamente. A temperatura retal não apresentou alteração significativa apenas com o uso do éter gliceril guaiacol, porém, houve uma tendência à redução desta, nos grupos que receberam a associação do mesmo com levomepromazina e benzodiazepínicos. Verificou-se, nos três grupos, uma taquicardia nos momentos iniciais, com normalização após 60 minutos, sendo esta mais acentuada em G2 e G3, observando-se paralelamente bradipnéia nos três grupos, apesar do grupo do éter g
