The practice of anesthesia frequently requires administration of a diverse set of medications under time pressure, without the aid of multiple checks on drug concentrations and infusion rates that occur in other acute care settings. This requires anesthesia providers to consistently and correctly perform complex calculations. In this infographic, through an interactive approach, we review the results of a drug calculation study in which anesthesia attending physicians and residents completed a written assessment of their computation acumen. We describe the factors that influence performance on this examination and factors that might reduce computation errors in the perioperative setting.
