The Effects of Propofol and Thiopental on Nitric Oxide Production and Release in Erythrocytes

Male patients aged 18-45 years with ASA (American Society of Anaesthesiologists) class I (normal, healthy person without any disease or systemic problem other than surgical pathology that does not cause a systemic disorder) who applied to the anaesthesiology and reanimation clinic outpatient clinic for preoperative preparation were planned to be included in the study. Women, patients with ASA class \>1, patients with known thiopental/propofol allergy and patients outside the age range of 18-45 years were excluded from the study. Venous blood samples will be taken from the patients included in the study and incubated with thiopental and propofol (dose: 100, 250, 500 and 1000µM) after appropriate procedures in the laboratory environment. . After incubation, all resuspensions will be subjected to flow cytometric analysis to evaluate erythrocyte NO synthase activity and erythrocyte-mediated NO release.All patients included in the study will be informed and their written and verbal consent will be obtained.
