 All patients scheduled for anesthesia should have a thorough physical examination.

 Because anesthetic drugs can drastically alter cardiovascular function, techniques to evaluate the cardiovascular system should be emphasized, especially in patients with primary cardiovascular disease or cardiovascular compromise secondary to other systemic disease (e.g. sepsis).Laboratory tests should include serum chemistry and a complete blood count.

 Regardless of the cause of cardiovascular compromise, the patient must be stabilized prior to anesthesia. This includes:Restoration of circulating blood volume (use of whole blood if necessary).Intravenous fluids must be used judiciously in horses with heart failure.Restoration of electrolyte balance.Serum [Ca++] and [K+] are often decreased.Promotion of cardiovascular function (e.g. IV fluids, positive inotropes, and analgesics).
