Beta adrenergic blockade reduces utilitarian judgement

Beta adrenergic blockade reduces utilitarian judgement

Noradrenergic pathways are involved in mediating the central and peripheral effects of physiological arousal. The aim of the present study was to investigate the role of noradrenergic transmission in moral decision-making. We studied the effects in healthy volunteers of propranolol (a noradrenergic beta-adrenoceptor antagonist) on moral judgement in a set of moral dilemmas pitting utilitarian o...

Beta-adrenergic blockade reduces myocardial injury during experimental cardiopulmonary resuscitation.

OBJECTIVES We attempted to determine the effects of beta-adrenergic blockade during cardiopulmonary resuscitation (CPR) on defibrillation rates and postresuscitation left ventricular function. BACKGROUND The results of previous studies suggest that propranolol administration can both reduce myocardial oxygen requirements and increase coronary perfusion pressure during CPR. METHODS Left vent...

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...

Beta-adrenergic blockade in hypertrophic obstructive cardiomyopathy.

Hypertrophic obstructive cardiomyopathy is a disorder of ventricular muscle characterized by asymmetrical hypertrophy and unusually rapid ventricular ejection of a normal stroke volume (Goodwin et al., 1960; Braunwald et al., 1964). The presence of a systolic gradient between the left ventricle and the aorta has been taken as evidence of obstruction of the ventricular outflow tract, but recent ...
