Different anesthesia methods will have different reactions after the drug is administered. If general anesthesia is administered, due to the suppression of the central nervous system by general anesthetic drugs, consciousness will disappear and the patient will enter a state of sleep, and will not feel any external painful stimuli, thus accepting the surgery. If local anesthesia is administered, the local anesthetic temporarily blocks the conduction function of certain peripheral nervous systems, causing a temporary loss of sensory and motor functions in the areas innervated by these nerves. At this time, the patient’s cerebral cortex is not inhibited and he or she is still conscious and can communicate with the surgeon. In comparison, general anesthesia can reduce the patient’s anxiety and tension, and allow the patient to complete the surgery while sleeping, so that the patient will have a better comfort level. Currently, many clinical procedures with local anesthesia are also compounded with intravenous general anesthetics so that the surgery can be performed smoothly and with higher patient satisfaction.
