    Journal: Am J Vet Res; 1987 Sep; 48(9):1372-5. PubMed ID: 2959181.
    Abstract:
    Cardiopulmonary effects of IV administration of lenperone (0.44 mg/kg) and glycopyrrolate (0.11 mg/kg) were determined in 6 healthy adult (2 to 5 years) Pointers during controlled ventilation with oxygen. Sufentanil was then administered as a loading dose (5 micrograms/kg, IV) and continually infused (0.1 microgram/kg/min) for 120 minutes. Lenperone-glycopyrrolate did not significantly affect heart rate, but induced a significant decrease in systemic vascular resistance, rate-pressure product, and mean arterial pressure, and significantly increased cardiac index. Administration of sufentanil did not significantly affect mean arterial pressure. Heart rate and rate-pressure product were significantly decreased during sufentanil infusion. Systemic vascular resistance gradually increased during the 2-hour sufentanil infusion and was not significantly different from base-line values at end of study. Cardiac index was not significantly different from baseline values during sufentanil infusion, except at 90 and 120 minutes, when it was significantly less. As administered in the present study, lenperone, glycopyrrolate, and sufentanil are safe and efficacious in adult dogs.
