Cloridrato de dexmedetomidina como medicação pré-anestésica ou sedativo em cães – relato de dois casos

Abstract

It is reported, two cases, and in the first, elective OVH surgery was performed. As MPA, 2.5 mcg / kg dexmedetomidine hydrochloride and 0.2 mg / kg IM methadone hydrochloride were used. The anesthetic recovery was quiet and uncomplicated and the animal was extubated after five minutes, discharged from the operating room 30 minutes later. In the second case, the third eyelid gland was buried. As sedative, 3.5 mcg / kg of dexmedetomidine hydrochloride and as an analgesic, 0.2 mg / kg of methadone hydrochloride IM was used. At the end of the surgical procedure, 0.4 mcg / kg IM atipamezole hydrochloride was administered. After 15 minutes, the patient recovered completely and could be referred for surgery. Both procedures had high SBP values and bradycardia, characteristic effects of dexmedetomidine use. In the first case, SBP remained between 150 and 180 mmHg, in the second, between 160 and 180 mmHg. From the reported cases, it was concluded that the use of dexmedetomidine was beneficial, providing adequate pre-anesthetic medication and sedation in these patients.
