Abstract: Volatile Anesthetic Agents (VAA) account for one of the reasons of high cost of anesthesia. Estimations of VAA consumed are done in an arbitrary manner to the advantage of the patient. This study aims to determine how Dion's method, a theoretical formula based on the laws of gas and physics that predicts VAA consumption in its vapor form, compares with the precision weighing method of VAA consumption in its liquid form. Ninety patients given general endotracheal anesthesia using sevoflurane whose vaporizers were weighted before and after a procedure to measure actual vapor consumed were included in this study. The obtained value was then compared to the computed value using Dion's method. This study determined that there was no statistical difference between the two values. Hence, Dion's method is viable alternative to determining the actual VAA consumed after a surgical procedure.
