The Effect of Desfluran On Global Dna Methylation

Peripheral venous blood samplesof patients will collected at two time points as follows: before the premedication and the induction of anesthesia (T₁): 120 minutes after the beginning of anesthesia (T₂). Anesthesia maintenance will be provided with 40% O₂ and minimum alveolar concentration (MAC) in 60% air with 6% desflurane. DNA will be obtained from blood samples with the help of DNA isolation kit, and global DNA methylation analysis will performed by ELISA method.
