Hemodynamic Effects of Intravenous Ephedrine Administration During General Anesthesia for Radiation Therapy in Cats
Ephedrine is used as a vasopressor in cats, but the hemodynamic effects of intravenous (IV) administration have not been characterized. This study evaluated the hemodynamic effects of IV ephedrine in 10 cats that developed hypotension during anesthesia. Cats received either saline (SE) or atropine (AE) before ephedrine for hypotension (mean arterial pressure < 60 mmHg). Hemodynamic variables were analyzed using a linear mixed-effects model. No significant differences were observed between groups in the response rat …
