Esophageal cancer is a common malignant tumor in modern society, which is usually treated by surgical resection, and anesthesia is required during the operation, and the choice of anesthetic drugs and anesthetic forms is the key to the smooth implementation of the operation. Currently, general anesthesia is commonly used in clinical practice, but the actual application effect of general anesthesia does not meet expectations, so some scholars have proposed that General anesthesia without opioid drugs combined with thoracic epidural anesthesia can obtain good anesthetic effects. In this study, a randomized controlled study was conducted to compare the anesthetic effects of conventional general anesthesia and opiate-free general anesthesia combined with thoracic epidural anesthesia, and it was found that: The overall anesthetic effect, pain degree, complication rate and other indicators of the latter are better than those of the former, which also indicates that the implementation of opiate-free general anesthesia combined with thoracic epidural anesthesia for surgical anesthesia during radical resection of esophageal cancer can further improve the anesthetic effect and ensure the surgical safety.
