The most common scenario for unclear speech after a trochanteric fracture of the femur is postoperative delirium, which may also be a brain lesion. Intertrochanteric femur fractures, now called intertrochanteric femur fractures, often occur in older patients. The main symptoms are painful swelling and limited mobility of the hip after a fall. Postoperative delirium due to the trauma of the injury and surgery (bleeding, anesthesia, and other factors) is the most common cause of unclear speech after surgery. This condition can be treated with psychosomatic therapy (e.g., medications such as quetiapine fumarate), but the effectiveness of treatment varies from person to person, and the symptoms usually resolve and disappear gradually after 3 to 5 days after surgery. In addition, there may also be complications of brain lesions, such as cerebral infarction appearing If there are symptoms should go to the hospital in time, under the guidance of the doctor’s standardized treatment of unclear speech, choking and coughing on drinking water and other symptoms, the need to perform a cranial CT to clarify the diagnosis. The medication should be used under the guidance of a doctor.
