INTRODUCTION Few clinical trials have provided evidence that epinephrine administration after out-of-hospital cardiac arrest (OHCA) improves long-term survival. Here we determined whether prehospital epinephrine administration would improve 1-month survival in OHCA patients. METHODS We analyzed the data of 209,577 OHCA patients; the data were prospectively collected in a nationwide Utstein-st...

Ephedrine, metaraminol, epinephrine and maneuvers like carotid sinus stimulation used during intraoperative period have been postulated to cause temporary spasm of the coronary vessels leading decrease supply myocardium precipitating myocardial infraction in non-obstructive arteries (MINOCA). As an anaesthesiologists, we should be aware that even a dose as small 25 mcg infiltrated along with lo...

The acute effects of epinephrine, norepinephrine, and isoproterenol on the plasma immunoreactive parathyroid hormone (iPTH) response were studied in 13 550-600 kg cows. Catecholamines were infused for 7.0 min. During epinephrine infusions at 0.08 mumol/min iPTH increased from 0.48+/-0.12 (mean+/-SE, ng/ml) to 1.09+/-0.18 ng/ml (P < 0.02). Small increases in plasma free fatty acids and glucose c...
