RESUMO:

Electroretinography (ERG) is a record of the electrical activity of the retina, an exame of great importance in the ophthalmic routine. It has high sensitivity to external interference, such as patient sedation, drugs used and monitoring equipment used. In the canine species, several anesthetic techniques and protocols have been proposed and described, however, even in the need for standardization, there is still no consensus on which provides a better examination with greater anesthetic safety. Thus, the present study aims to compare the performance of the ERG, according to the guidelines of the International Society of Clinical Visual Electrophysiology (ISCEV) in six healthy Molinois Belgian Shepherd dogs, between 1 and 5 years old, randomly submitted and at intervals of 15 weeks. days at the two anesthetic protocols: 0.02 mL / kg, intramuscularly (IM), of the TDex solution (50 mg of tiletamine-zolazepam lyophilisate diluted in 25% butorphanol 25% solution and 0.125 mg 50% dexmedetomidine); and 0.2 mg / kg butorphanol (IM), 5 mg / kg propofol (IV) and vaporized isoflurane in order to maintain superficial surgical plan according to clinical parameters. All animals were intubated, bandaged for dark adaptation, received rocuronium (0.05 mg / kg IV) and had their vital parameters monitored via a multiparameter battery and covered with a red filter. Both protocols proved to be effective for ERG examination. Inhaled anesthesia provided higher retinographic responses, although statistically both were similar, shorter total examination time and better recovery. The incidence of anesthetic complications was similar, but hypotension was more frequent with isoflurane, while bradicardia and hypercapnia was more frequent in the Tdex study. Not only the choice of anesthetic but also the adjustment of the anesthetic plan was determinant for the acquisition of quality records.
