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 کاملAstrocytoma presenting with apnea and sinus arrest.
Although some vascular lesions of the central nervous system are known to cause abnormalities in the control of breathing, association between astrocytoma and combined cardiorespiratory abnormalities in the adult is distinctly unusual. We present a case of a 52-year-old man whose only features of astrocytoma consisted of episodes of apnea and sinus arrest followed by prolonged alveolar hypovent...
متن کاملConcurrent atrioventricular block, sinus arrest and pneumothorax in a dog secondary to vehicle accident
In human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating QRS amplitude (electrical alternans). However, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. A 3-year-old male crossbreed dog was presented with a history of car accident. Thoracic au...
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...
