Vomiting may indeed occur after general anesthesia, which is related to the patient's own situation and anesthetic medication. But vomiting occurred one week after operation, which had nothing to do with anesthesia. Narcotic drugs usually metabolize quickly. If the postoperative analgesia pump is used, some painkillers will cause vomiting and other reactions. It is rarely seen that patients with general anesthesia still have vomiting symptoms three to five days after operation.
If possible, it is suggested to check the CT and MRI of the head to see if there is any bleeding or other conditions, or consider it as a symptom of the nervous system.
