Abstract

Dobutamine is routinely used to improve cardiovascular function in anaesthetized horses. However, dobutamine in conscious horses is insufficiently investigated. Ten research horses that were already instrumented for a preceding trial were included into the study. Cardiovascular variables were...

Comparação dos efeitos hemodinâmicos da efedrina ou dobutamina em equinos anestesiados com Isofluorano, 2018, pp 78 pp.
Abstract

Reasons for performing study: Cardiac output does not always increase with dobutamine administration in anaesthetised horses and information on peripheral perfusion is lacking. Objectives: To determine the effect of intravenous (i.v.) dobutamine infusion with and without a concurrent 20 mL/kg...

Abstract

Echographic parameters of the left ventricle during an atropine-low dose dobutamine stress test in adult horses is described. Six healthy 7-15y untrained Kord horses were used. Heart rate and left ventricular B- and M-mode dimensions were recorded at baseline during administration of 35 mg/kg...
