Effects of TIVA and Inhalation Anesthesia on Oxidative Stress Factors During Hypotensive Anesthesia

Anesthesia Clinical Trial

Official title:
Effects of TIVA and Inhalation Anesthesia on Oxidative Stress Factors During Hypotensive Anesthesia

Clinical Trial Summary

Total intravenous anesthesia (TIVA) and inhalation anesthesia are two anesthesia methods that can be preferred for the maintenance of anesthesia. Sevoflurane and propofol are drugs used frequently in these methods. This study aims to investigate and compare the effects of inhalation anesthesia using sevoflurane and TIVA using propofol on oxidative stress in patients undergoing controlled hypotensive anesthesia.

Clinical Trial Description

Controlled hypotension is defined as keeping systolic blood pressure in the range of 80-90 mmHg or mean arterial pressure in the range of 50-65 mmHg. Pharmacological and non-pharmacological methods can be used to achieve controlled hypotension. Intravenous anesthetics, inhalation anesthetics, opioids, calcium channel blockers, beta blockers, nitrate derivatives are frequently used drugs for this purpose. General anesthesia maintenance is applied in two ways: total intravenous anesthesia (TIVA) and inhalation anesthesia. The pharmacokinetic and pharmacodynamic properties of drugs used in both methods are quite different. Products of the body's oxidant antioxidant balance can be measured by biochemical methods and information about this balance can be obtained. Thiols are the regions of proteins most susceptible to oxidation, and the conversion of thiols to disulfides and oxyacids is the earliest marker of radical-mediated protein oxidation. Total antioxidant status (TAS) shows the total effect of all antioxidants in the human body and total oxidant status (TOS) shows the total effect of oxidants. In this study, it was aimed to investigate and compare the effects of inhalation anesthesia using sevoflurane and total intravenous anesthesia using propofol on oxidative stress in rhinoplasty cases under controlled hypotension. This assessment was planned using TAS (total antioxidant status), TOS (total oxidant status), Catalase, Myeloperoxidase (MPO), Total Thiol, Native Thiol and Disulfide parameters. ;
