If the patient is mentally abnormal after surgery, the effects of anesthesia should be considered, and no treatment is needed if this occurs. If it is caused by other reasons, we can consider choosing medication (such as diazepam, lorazepam) and psychotherapy, and follow the doctor’s instructions for regular review. 1. Medication: If the patient’s spirit is abnormal after the operation, such as nervousness and anxiety, unable to sleep and other symptoms, consider taking anti-anxiety drugs, such as diazepam, lorazepam, etc.; if the patient has hallucinations and fantasies, take a small dose of olanzapine, haloperidol, etc., according to the doctor’s instructions. 2. Psychotherapy: If the postoperative patients have excessive mental tension, anxiety and depression, they can consider psychotherapy to get comfort and support from professional doctors, reduce anxiety and depression, and eliminate inner pain. 3. Regular review: CT or blood test can be done to confirm whether there are specific lesions such as brain diseases or infections, and if there is any abnormality, targeted treatment should be taken in a timely manner. Regardless of any surgery, there are certain risks or chances of after-effects after surgery, so you must choose a regular hospital for the surgery. If there is any mental abnormality after the surgery, you should inform your doctor in time and follow the doctor’s instructions for treatment.
