Cardiovascular and Respiratory Effects of Medetomidine in Dogs and Influence of Anticholinergics
Acta Veterinaria Scandinavica volume 30, pages 401–408 (1989)
Abstract
A total of 10 laboratory beagles was used to determine the cardiovascular and respiratory effects of medetomidine. The effects of atropine sulphate and glycopyr-rolate on heart rate were also observed. Xylazine was included as a positive control. Medetomidine induced initial hypertension followed by a longer lasting hypotensive period. Evident bradycardia with second degree atrioventricular blocks and decrease in respiratory frequency was observed. Atropine sulphate and glyco-pyrrolate transiently abolished the bradycardic effect of medetomidine. Xylazine exhibited a similar cardiovascular and respiratory pattern to medetomidine.
