Moodiness after general anesthesia surgery usually improves. After general anesthesia surgery, there are many factors that lead to emotional irritability, including wound pain, anesthetic drugs, catheterization, respiratory insufficiency, respiratory tract stimulation, etc. If there are these factors, it may lead to emotional irritability. After surgery, with the gradual recovery of the patient, the above factors can be gradually eliminated, pain can be gradually relieved, respiratory function can be gradually restored, anesthesia drugs can be gradually metabolized, and then emotional irritability can gradually improve. When the patient is irritable, it is necessary to actively search for the cause and carry out standardized treatment, such as pain relief treatment, oxygen therapy, infusion therapy, etc., which can promote the relief of emotional irritability.
