Common postoperative anesthesia-related complications include: 1. Wound pain caused by surgical trauma. Actually, this should not be attributed to general anesthesia, but because anesthesia often accompanies surgery, postoperative pain is relegated to the anesthesiology department for management. The first concern of anesthesiologists is postoperative pain, which must be dealt with for patients. Because pain comes from surgical trauma on the one hand, and some anesthetic analgesics on the other hand, can cause hypersensitivity in the patient’s body. If analgesics are not used, the patient’s sensitivity to pain may not be that high, while the use of some analgesics during surgery may lead to the patient’s hypersensitivity to pain, so that postoperative analgesia is very important; 2, nausea, vomiting. During anesthesia, the effect of some anesthetics, especially opioids, can lead to nausea and vomiting, which is also our key concern; 3. Hypothermia. The patient’s body heat is emitted in a large amount during the operation, in addition, after the application of anesthetics, the patient’s own heat production will be greatly reduced, basically the patient is in a relatively low state of body temperature during the operation. So we have to do a good job of protection to prevent the occurrence of hypothermia after anesthesia, we have to start to insulate the patient from the surgical process, to take precautions, and to prepare for hypothermia after surgery as well; 4. Dizziness and lightheadedness. Although the vast majority of the effects of postoperative anesthetics have disappeared, but the remaining part of the patient will cause dizziness and lightheadedness; 5. Anesthesia operations, including tracheal intubation anesthesia, etc., can also cause discomfort in the throat of the patient.
