Beta-blockade and surgery
Early studies with propranolol and other betablockers, mainly employing intravenous administration, demonstrated elective and prophylactic control of supraventricular and ventricular tachyarrhythmias periand postoperatively. There has been particular focus on esmolol, which is an ultrashort acting beta1 selective antagonist that is rapidly hydrolysed by red cell esterases with a half life of ab...
متن کاملBeta-adrenoceptor blockade and anesthesia
A potential for impaired cardiovascular performance among anesthetized patients due to preoperative treatment with propranolol was considered based on clinical observation of sudden, irretractable cardiac failure in five patients. As a result, a recommendation to terminate beta-adrenoceptor therapy prior to general anesthesia was advanced. During the ensuing decade many clinical researchers sou...
متن کاملEsmolol and beta-adrenergic blockade.
Tachycardia often presents difficult management problems in anesthesia. Because it increases myocardial oxygen demand so sharply, tachycardia can quickly place patients at risk of myocardial ischemia. It can occur for any number of reasons. Deepening the anesthetic, either with inhalation agent or opioids, will ablate increases in heart rate, but changes in heart rate are often transient and ch...
متن کاملBeta blockade in lithium tremor.
Practolol, propranolol, and placebo have been tested on an objective test of lithium induced tremor. Both beta-blocking agents produced significantly more tremor than the placebo. It is argued that lithium induced tremor is closer to essential than to physiological tremor.
متن کاملIntermittent claudication complicating beta-blockade.
Intermittent claudication is an occasional side effect of beta-adrenergic blockade' but clinical details are lacking. Beta-blocking agents may exacerbate intermittent claudication in patients with severe peripheral arterial insufficiency.2 The following cases suggest that they may also provoke claudication in patients with previouslv asymptomatic peripheral arterial disease. Case 1 A man aged 5...
