The effect of the components of general anesthesia on the level of carcinoembryonic antigen in the blood serum of patients with cancer of the large intestine

The effect of calipsol and thiopental (the most frequent drugs used for basis anesthesia), as well as their combinations with narcotic analgesics fentanyl, morphine, promedole and a neuroleptic droperidol on the level of carcinoembryonic antigen (CEA) in patients with colonic cancer has been studied. A significant effect of anesthetics on CEA level in the postoperative period has been established. The lowest CEA level was observed when calipsol, morphine, and promedole were used as components of narcotic analgesics.
