Halothane is one of the most used inhalation anesthetic, but produces cardiovascular depression, due to decreased cardiac output and peripheral vascular resistance. This study aimed to compare the effect of Lactated Ringer and 0,01% carbazochome (Adrenoplasma)for treatment of arterial hypotension produced by halotano in dogs. Anesthesia was induced with propofol and maintained with 1,3% of halothane.Dogs of group A received the infusion of Adrenoplasma and dogs of group B received the infusion of the Lactated Ringer. The infusuin rate was 20 ml/kg/hr in both groups during the anesthesia. All dogs were maintained under controlled ventilation. Heart rate, eletrocerdiogram, arterial blood pressure, expired CO2 concentration, tidal and minute volume, hemoglobin oxygen saturation, bleeding time and rectal temperature were observed before and 30 minutes after the anesthetic induction and at 15,30, 45 and 60 minutes after beginning of fluis. Sistolic and mean arterial blood pressure increased only in animals treated with Adrenoplasma when compared to the value observes immediately before the administration of fluids.Rectal temperature decreased in all animals. There was no difference in the bleeding time. Adrenoplasma may be used for treatment of the arterial hypotension due to halothane anesthesia in dogs.
