FentaSim is an educational tool used for understanding and visualizing the effect-site concentration of fentanyl.

Anesthesiologists and other clinicians involved with anaesthesiology or pain medicine, from residents to the very experienced, will find FentaSim a valuable tool for understanding rational dosing strategies tailored to individual patients.

The simulations use a (weight proportional) pharmacokinetic model published by Scott et al. to estimate and graph plasma and effect-site concentrations, and to estimate the decrement time to a user specified effect-site concentration.

Drug entry system allows recording of fentanyl bolus dose and infusion rates real-time or retrospectively from intra-operative record. Dosing history is limited to ten hours.
