The patients were randomized into two groups medium flow anesthesia (MeFA) and minimal flow anesthesia (MiFA). While MeFA received medium flow anesthesia with 2 lt/min, MiFA received minimal flow anesthesia with 0.5 lt/min fresh gas flow. In both groups dynamic compliance values, peak inspiratory pressure (PIP) values, total inhalation anesthetic drug consumption, total remifentanil drug consumption, duration of anesthesia, and duration of surgery were recorded. The FVC, FEV1, and FEV1/FVC values of the patients in both groups were evaluated and noted 24 hours before the operation, after the operation 2nd, 8th, and 24th hours.
