Comparison of minimal-flow sevoflurane versus desflurane anesthesia: randomized clinical trial.

Background And Objectives: Minimal-flow anesthesia provides various advantages, such as reduced environmental pollution, proper humidification and warming of anesthetic gases, and reduced costs. The aim of this study was to compare the cost-effectiveness of minimal-flow sevoflurane and desflurane anesthesia and their effects on hemodynamics, postoperative recovery, respiratory parameters, and liver and kidney functions.

Methods: A total of 60 ASA I-II patients aged 18-70 years who underwent posterior spinal instrumentation were included in the study.
