Abstract

this study aims to evaluate the ecacy of Levo-bupivacaine with the addition of a small dose of cisatracurium by sub-Tenon’s injection on akinesia and mydriasis. Then, to evaluate if such a small dose of cisatracurium could determine a systemic neuromuscular blockade, despite the way of administration. Forty cats were anesthetized for intra-ophthalmic surgery with butorphanol 0,2 mgkg-1, dexmedetomidine 15 mcg/kg and midazolam 0,2 mgkg-1 IM and intubated to receive oxygen and isouorane by mechanical ventilation. The animals were divided in four groups. Group L received 1.25 mgkg-1 L-bupivacaine, administered by peribulbar injection; group CL received the same dose of L-bupivacaine, combined with 0.01mg/kg of cisatracurium; group C received 0.01 mg kg-1 of peribulbar cisatracurium; group GC received 0.01 mg kg-1 of cisatracurium intravenously. Physiological variables and oculomotor activity were measured before and up to 30 minutes after peribulbar injection.
