Chronic postoperative pain is an entity that is usually neglected by anesthetists, but several studies show that the choice of anesthetic technique may interfere with this prevalence. Esmolol is a selective beta-blocker of ultra fast duration that has been studied as a perioperative venous adjuvant with antihyperalgesic and opioid sparing action. The investigators ventured the possibility of this anti-hyperalgesic effect attenuating the chronic pain syndrome post-mastectomy.
