Epi and LA

Q: What's the etiology behind lactic acidosis from intravenous epinephrine infusion?

Answer: Out of all the intravenous vasopressors used in ICU, epinephrine is known to be the most notorious to cause lactic acidosis. Two mechanisms have been proposed. Postulation is that they may be happening together. One is the increased glycolytic activity in skeletal muscles and second is the hypoperfusion of gut causing lactic acidosis.
