Abstract

Objective: Cost comparison between three common anesthetic agents. Design: Retrospective analysis. Patients had been randomized to anesthetic maintenance with either desflurane, sevoflurane, or propofol. Setting: Operating room in an academic medical center Patients: 103 patients undergoing general endotracheal anesthesia. Patients were ASA class I-III and between 18 and 75 years old. Cardiac, Neurologic, and regional cases were excluded. Outcome Measures: Volatile anesthetic cost was determined using the following formula: Cost = [(concentration) (FGF)(duration)(MW)(cost/ml)]/[2412)(D)]. To determine propofol cost, average infusion rate (mcg/kg/min.), patient weight, and duration were measured. Cost for each agent was then divided by surgical time to compare the results on a cost/min. basis. Results: Per minute of surgery, propofol was the least expensive agent for anesthetic maintenance at $0.12/min. Sevoflurane cost $0.18/min and desflurane cost $0.48/min. The differences between all three agents were statistically significant (p <0.05). Propofol maintenance was associated with a higher intra-operative fentanyl dose. The average fentanyl dose in the propofol group was 468 mcg, sevoflurane was 321 mcg, and desflurane was 284 mcg. There was no association between intra-operative fentanyl dose and anesthetic maintenance cost per minute of surgery. Surgical time did not significantly differ between the three groups and averaged over three hours. Conclusion: Anesthetic maintenance with propofol may help peri-operative physicians deliver care in the most cost effective manner possible.
