Evaluation of a xylazine-ketamine hydrochloride combination in the cat.
Cardiopulmonary function was assessed in healthy cats given a xylazine-ketamine hydrochloride combination intramuscularly. Cardiac output, heart rate, stroke volume and cardiac index were significantly decreased. Systolic, diastolic and mean arterial blood pressure were also significantly decreased. Systemic vascular resistance and central venous pressure were significantly increased. Blood gas values remained stable. In conclusion, significant cardiovascular depression was noted in normal cats given the xylazine-ketamine combination at the dosages listed.
