Perioperative betaadrenergic blockade

Has been shown to reduce the incidence of intraoperative and postoperative ischemic episodes and appears to be superior to prophylaxis with a calcium channel blocker alone. B. Eligibility is determined by the presence of any two minor criteria (age greater than 65, hypertension, current smoker, cholesterol greater than 240 mg dL, or non-insulin dependent diabetes) or any single major criterion (high-risk surgical procedure, history of transient ischemic attack or stroke, insulin dependent...

Pertinent cardiac history

Cardiac reserve limited exercise tolerance in the absence of significant pulmonary disease is the most striking evidence of decreased cardiac reserve. If a patient can climb several flights of stairs without symptoms, cardiac reserve is probably adequate. B. Angina pectoris an increase in heart rate is more likely than hypertension to produce signs of myocardial ischemia. C. Previous myocardial infarction the incidence of myocardial reinfarction in the perioperative period is related to the...

Uptake of the inhaled anesthetic

Solubility The solubility of inhaled anesthetics is defined as the amount of anesthetic agent required to saturate a unit volume of blood at a given temperature and can be expressed as the blood gas partition coefficient. The more soluble the agent, the greater the uptake into the pulmonary capillaries. The solubility of the inhalation agent in blood is the most important single factor in determining the speed of induction and recovery in individual patients. B. Cardiac output A high cardiac...
