Propofol is one of the most commonly used anesthetics in the world. However, the dose-response of propofol was remarkable variety. Herein, this study aims to investigate the possible association of gene polymorphism and propofol susceptibility, and to research more precise infusion model of this drug.
Patients undergoing gastrointestinal endoscopy will be recruited. Anesthesia is induced with propofol via TCI at 1.5µg/ml, and increases 0.5µg/ml for every 3min until OAA/S score 0. During this period, OAA/S score will be evaluated every 1min until OAA/S score 0. At this moment, the blood concentration of propofol, the doses of propofol, the onset time and BIS are recorded, and blood sample for gene polymorphism detection were required.

gene polymorphism of propofol susceptibility
combination of the blood concentration of propofol (ng/ml) with the onset time(min) at OAA/S score of 0 to demonstrate propofol susceptibility, the gene polymorphism of propofol susceptibility will be detected with the blood sample of subjects.
Time frame: from anesthesia induction to the end of the gastrointestinal endoscopy
