There have been colossal technological advances in the use of simulation in anesthesiology in the past 2 decades. Over the years, the\nuse of simulation has gone from low fidelity to high fidelity models that mimic human responses in a startlingly realistic manner,\nextremely life-like mannequin that breathes, generates E.K.G, and has pulses, heart sounds, and an airway that can be programmed\nfor different degrees of obstruction. Simulation in anesthesiology is no longer a research fascination but an integral part of resident\neducation and one of ACGME requirements for resident graduation. Simulation training has been objectively shown to increase\nthe skill-set of anesthesiologists. Anesthesiology is leading the movement in patient safety. It is rational to assume a relationship\nbetween simulation training and patient safety. Nevertheless there has not been a demonstrable improvement in patient outcomes\nwith simulation training. Larger prospective studies that evaluate the improvement in patient outcomes are needed to justify the\nintegration of simulation training in resident education but ample number of studies in the past 5 years do show a definite benefit\nof using simulation in anesthesiology training. This paper gives a brief overview of the history and evolution of use of simulation\nin anesthesiology and highlights some of the more recent studies that have advanced simulation-based training.
