Effect of Propofol and Desflurane on Nucleic Acid of Liver Circulating Tumor

Propofol general anesthesia group (P group) : intravenous propofol infusion was slowly pushed until consciousness disappeared, and then anesthesia was maintained at 4-8 mg/kg/h. In the general anesthesia group with desflurane (group D), intravenous propofol infusion was slowly pushed until consciousness disappeared, and then anesthesia was maintained with 4-6% desflurane. The analgesic and muscle relaxant regimens were the same in both groups except for sedative drugs. All patients were treated with no medication before operation, and the operation was completed under endotracheal intubation and general anesthesia. The amount of propofol or desflurane was adjusted according to BIS or MAC values and hemodynamic changes during operation. Add 10mg of rocuronium every half hour. Vasoactive drugs can be used to maintain hemodynamic stability during the operation, and corresponding records should be made
