Monitors that show intravenous (IV) drug concentrations currently do not exist. However, using real-time displays of intravenous anesthetic concentrations and effects could significantly enhance intraoperative clinical decision-making. Pharmacokinetic models are available to estimate past, present and future drug concentrations in the brain, and pharmacodynamic models are available to predict the drug's associated physiological effects. An interdisciplinary research team developed a new graphic display incorporating these models to show the predicted concentrations and effects of anesthetic drugs in real-time. To evaluate the effectiveness of the display on the management of anesthesia, 15 anesthesiologists participated in a computer-based simulation study. Anesthesiologists maintained drug concentrations closer to an optimal target level when they used the prototype anesthesia drug display. Participants also reported lower levels of workload with the display and rated the display as a useful addition to anesthesia monitoring.
