Cardiopulmonary and behavioral effects of fentanyl-droperidol in cats.
The combination of the narcotic fentanyl (0.4 mg/ml) and the tranquilizer droperidol (20 mg/ml) was injected into 12 healthy adult cats at a rate of 1 ml/9 kg of body weight, sc. Arterial blood pressure, heart rate, respiratory frequency, PaCO2, and PaO2, arterial pH (pHa), and rectal temperature were measured before and 30, 60, 90, and 120 minutes after injection of fentanyl-droperidol. Respiratory frequency was decreased significantly (P less than 0.05) and heart rate increased significantly (P less than 0.05) at all measurement intervals after drug administration. Observed decrements in arterial blood pressure were not significant. Arterial PO2, PCO2, and pH did not change significantly. A significant (P less than 0.05) decrease in body temperature was measured 90 minutes after drug administration. All cats were calm, tractable, and frequently assumed lateral recumbency after administration of fentanyl-droperidol. This maximal tranquil state was determined to be 30 to 60 minutes after drug administration.
