Update in perioperative medicine 2012.

Perioperative medicine is an increasing area of research focus that brings together internists, anesthesiologists, surgeons, and hospitalists. A medical team approach to ensure the best possible patient outcomes has fostered collaborative strategies across areas of patient care. We review 8 seminal articles in the field of perioperative medicine. Each article was published in either 2011 or 2012 and adds to care strategies in the areas of perioperative cardiac medicine, pulmonary care, blood transfusion decision making, and medication management.
