Dizziness after general anesthesia may be due to residual general anesthetic drugs. In order to ensure that the patient is in a state of general anesthesia, that is, in a state of deep sleep during surgery, continuous anesthesia is needed to keep the patient in a sleep state without intraoperative knowledge, so the general anesthetic drugs used are continuous drugs. At the end of surgery, the metabolism of these general anesthetics requires a process. Although the patient wakes up, the anesthetic in the body takes a longer time to be metabolized. Although the patient has woken up, but there is still a certain concentration of drugs in the body, the patient will experience dizziness. Of course, dizziness is also related to surgery, and dizziness is also related to factors such as reduced physical strength and weakness of the patient after major surgery.
