The Relationship of Sevoflurane Consumption With Metabolic Age

Study Overview
=================
Brief Summary
-----------------
The aim of this clinical study is to determine the consumption of sevoflurane, which is one of the inhalation anesthetics, with metabolic age and basal metabolic rate. The basal metabolic rates and metabolic ages of the patients who will be given sevoflurane- maintained general anesthesia were measured preoperatively. The relationship between the amount of sevoflurane consumption and the measured data of the patients in the postoperative period was examined.

Detailed Description
-----------------
Standard monitoring, BIS, TOF (train of four) were performed from the premedication application. Aspect A 2000 (Aspect Medical Systems, Newton) monitor and single-chip BIS electrodes will be used for BIS. The total amount of sevoflurane consumed and MAK values of these components will be recorded. Chronological age, metabolic age, BMR, height, weight, ideal body weight, BMI, body adiposity, body fluid ratio, body fluid care, fat mass, lean body weight, muscle registered, visceral adiposity, obesity degree in the preoperative period of the patients. Values, ASA scores and demographic data will be recorded for the operation process, cutting time, anesthesia time, extubation time, total sevoflurane consumption throughout the case, and the relationship with basal metabolism and metabolic age will be evaluated.
