The most common cause of irritability in patients with cerebral hemorrhage is mainly due to increased intracranial pressure. If the irritability is caused by increased intracranial pressure and the amount of bleeding reaches the indication for surgery, surgical treatment should be considered. If the amount of bleeding is small, you can use some dehydrating drugs to lower the cranial pressure or give analgesic or sedative treatment. If the irritability of the brain hemorrhage is caused by the use of a ventilator, analgesia and sedation may also be used. In addition, patients who have uncomfortable experiences can also cause irritability, such as urinary catheter clamping and uncomfortable position, which can cause irritability. Therefore, irritability in patients with cerebral hemorrhage should be managed mainly according to the cause of irritability.
