Sevoflurane Versus Propofol: Effect on Stress Response

Stress is defined as hormonal and metabolic changes in the biological system that follow any injury. The stress response occurs as a general systemic response to injury and includes a wide range of endocrinological, immunological and hematological effects. The level of stress in the surgical process can affect not only the patients outcome but also the overall health system. The two main agents used in maintenance for general anesthesia are inhalation and intravenous anesthetics. Both inhalation anesthesia and TIVA (Total Intravenous Anesthesia) approaches provide general anesthesia suitable for surgical operations. However, the mechanisms of action of these two methods differ and are not fully understood. The aim of investigators' for this study was to investigate the effect of different anesthetic agents on stress inflammatory response in the preoperative, peroperative and postoperative periods.
