Abstract

The aim of this study was to evaluate four protocols of loco regional anesthesia for ophthalmicprocedures that could provide safety and life support, in addition to maintain intraocular pressurestable, with eye centralization and eyelid akinesia. 20 New Zealand rabbits were used to perform localanesthesia by retrobulbar block with four protocols: 2% lidocaine with epinephrine, 2% lidocainewithout epinephrine associated with tramadol, 1% ropivacaine and bupivacaine 0.5 %. Each animalreceived an anesthetic volume of 1 mL. All anesthetic protocols used promoted eyelid akinesia and centralization of the eye during the assessment period. The retrobulbar block with the proposedanesthetic protocols proved to be feasible and safe for the maintenance of intraocular pressure,invasive blood pressure and pupillary diameter and can be used in intraocular surgeries, respecting thetime of action of each anesthetic. All protocols showed an excellent blockage action but bupivacainepromoted the highest pupil diameter compared to the other drugs tested.
