Pathophysiology of major surgery and the role of enhanced recovery pathways and the anesthesiologist to improve outcomes

Abstract

Enhanced recovery pathways have been increasingly adopted into surgical specialties with the aim of reducing the stress response and improving the metabolic response to surgical insult. Enhanced recovery pathways encompass a large range of perioperative elements that together aim to restore a patient's gut function, mobility, function and well-being to preoperative levels as soon as feasible after major surgery. There is increasing evidence that rapid recovery and return to normal function reduces complications. This may not just have a benefit by reducing morbidity and mortality but also have an effect on long-term survival. There also may be additional benefits for patients with cancer.
