Electrocardiographic parameters of captive lions (Panthera leo) and tigers (Panthera tigris) immobilized with ketamine plus xylazine.

Twenty-seven healthy captive lions (Panthera leo) and 13 healthy captive tigers (Panthera tigris) from São Paulo Zoo (Fundação Parque Zoológico de Sã Paulo, São Paulo, Brazil) collection were selected for this study. They were anesthetized with ketamine (10 mg/kg) combined with xylazine (1-2 mg/kg) for physical examinations, hematologic and serum chemical analysis and electrocardiogram recording. The main aim of this research was to gather initial information about normal electrocardiographic parameters of large felids.

Effects of propofol on the electrocardiogram and systolic blood pressure of healthy cats pre-medicated with acepromazine.

Objective: To obtain and analyze the electrocardiogram and systolic blood pressure of cats before, during, and after a continuous infusion of propofol.

Study Design: Prospective, uncontrolled experimental trial.

Animals: Twenty healthy adult crossbred male and female cats aged between 3 and 5 years, weighing 2.
