Esmolol — just another beta blocker?

Electrophysiological effects of sotalol--just another beta blocker?

The electrophysiological effects of intravenous sotalol hydrochloride (0.4 mg/kg) were assessed in 24 patients, including 13 with the Wolff-Parkinson-White syndrome, undergoing routine electrophysiological study. Fifteen to 30 minutes after sotalol administration there was a significant increase in sinus cycle length and in sinus node recovery time. There was a small increase in the AH interval...

Esmolol: a unique Beta-blocker in maintaining cardiovascular stability following neurosurgical procedures.

PURPOSE Patients with increased intracranial pressure (ICP) are prone to severe cardiac and or cerebral complications following emergence from general anesthesia and especially post-extubation phase. Administering beta blockers including esmolol is believed to be helpful in providing a stable hemodynamic at the end of the surgery and recovery stages and reducing recovery phase length. METHOD ...

Managing critically ill patients with esmolol. An ultra short-acting beta-adrenergic blocker.

Esmolol is a new intravenous beta-adrenergic blocker with an ultrashort (nine-minute) elimination half-life, which has been studied predominantly for control of supraventricular tachycardia and management of certain types of hypertension. Clinical studies indicate that the efficacy of esmolol is equivalent to that of propranolol and verapamil for control of supraventricular tachycardia and to s...

Esmolol 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...
