Resumo
O objetivo deste estudo foi o de avaliar uma associação anestésica com e sem a utilização de relaxante muscular não-despolarizante e seu efeito sobre a pressão intra-ocular de eqüinos. Também objetivou-se uma técnica anestésica sem efeitos adversos que possa ser utilizada em procedimentos e cirurgias oftálmicas nesta espécie animal. Para tanto, dezesseis eqüinos foram divididos aleatoriamente em dois grupos de oito animais cada. Os animais do grupo I foram pré-medicados com romifidina, induzidos com tiletamina/zolazepam e a anestesia foi mantida com halotano e vecurônio. Os animais do grupo II receberam a mesma associação anestésica, com exceção do vecurônio. No decorrer do experimento, a pressão intra-ocular, a pressão arterial e a freqüência cardíaca foram avaliadas em diferentes momentos. A associação anestésica composta pela romifidina, tiletamina/ zolazepam e halotano com e sem vecurônio não promoveu alterações estatisticamente significativas na pressão intra-ocular de eqüinos e o seu uso é exeqüível em procedimentos oftálmicos nesta espécie animal.
The purpose of this study was to evaluate an anesthetic association with and without the use of a nondepolarizing muscle relaxant agent and its effect on intraocular pressure of horses, and also obtain an anesthetic technique free of adverse effects for ophthalmic surgeries in this specie. Sixteen horses were randomly divided in two groups of eight horses each. In group I, horses were pre-medicated with romifidine, anesthesia induced with tiletamine/zolazepam and maintained with halothane and vecuronium. Horses of group II received the same anesthetic association except for vecuronium. Intraocular pressure, arterial pressure and heart rate were evaluated in different moments during the experiment. The anesthetic association composed by romifidine, tiletamine/zolazepam and halothane with and without vecuronium did not promote statistically significant alterations in horses intraocular pressure and its use is practicable in ophthalmologic procedures.
