Background: Desflurane is relatively newer volatile anesthetic in clinical practice with many advantages. Unfortunately, it is comparatively costlier. The present observational study is aimed to evaluate the consumption pattern and cost of Desflurane based minimal flow anesthesia with regards to different durations of anesthesia.
Methods: Twenty adults of American Society of Anesthesiologists’ class I and II of either sex were enrolled for the study with informed consent during November 2015 to January 2016. Anesthesia was performed using Intermed Penlon sigma Alfa Desflurane vaporizer and Penlon Prima SP2 workstation. Age and opioid compensated minimum alveolar concentration was fixed for each patient and was monitored using Penlon SP M8 monitor and its attached anesthesia gas monitoring system. Bispectral index was used in affordable patients to monitor depth of anesthesia. Data of Desflurane consumption was collected from the digital numerical display on the vaporizer screen. Statistical analysis was done using INSTAT software and cost was calculated from maximum retail price.
Results: Data from 20 patients consisting 60% male (mean + standard deviation age of 39.8 + 16.9 years and weight of 59.7 + 12.52 kilograms) were analyzed. Gender had no effect on consumption of Desflurane. Older patients (>60 years) consumed less than the younger (p
