Abstract

Objective: The safe implementation of low-flow anesthesia has greatly facilitated, because of the anesthesia machines monitors that analyze the anesthetic gas composition detailed way, increase the knowledge of anesthetics. In this research; we aimed to compare the effects of high and low-flow general anesthesia methods on the peroperative hemodynamics, anesthesia depth and postoperative recovery time in patients with abdominal surgery in the presence of bispectral index monitoring.

Methods: ASA I-II, 40 patients; 18 - 75 ages, who will have abdominal surgery were randomly divided into two groups, after the approval of the ethics committee (2016 - 06/02) and the patients. Anesthesia induction was performed with 6 mg/kg thiopental sodyum, 1 μg/kg remifentanil and 0.5 - 20 μg/kg/min remifentanil infusion, 4 - 6% desflurane after routine ECG, blood pressure, SpO₂ and BIS monitorization to all patients. In the low-flow group after the first 10 min 4 lt/min fresh flow, the flow was reduced to 1 lt/min. Values of the heart rate, MBP, SpO₂, FiO₂, BIS, tympanic temperature at before induction and after intubation and the minutes of 15^th, 30^th, 45^th, 60^th, 90^th,120^th are recorded. Lactate and COHb values were measured in blood gas analyzes performed at 30^th and 90^th minutes.

Results: When SpO₂ and FiO₂ values measured in different time periods of the individuals in both two groups were compared, differences between the minutes of 30^th, 45^th, 60^th, 90^th, 120^th were significant.

Conclusion: In this research; it is revealed that low-flow anesthesia which has advantages in many aspects can be used safely like high flow anesthesia when applied with adequate information equipment, appropriate anesthesia devices and necessary monitorizations.
