The best time to resuscitate a brain hemorrhage is usually within 6 hours of the onset of the attack. Cerebral hemorrhage is one of the more common and brain-threatening diseases, and the earlier the attack is resuscitated, the better the outcome and the less harmful the complications. Studies have shown that four-fifths of hematomas increase in size within 6 hours of onset. The longer the hematoma is compressed, the higher the probability of irreversible damage to the surrounding brain tissue, increasing the rate of disability and death. Factors contributing to the growing hematoma include overhydration, respiratory obstruction, and sustained elevation of blood pressure, etc. Therefore, patients need to receive resuscitation treatment within 6 h of the onset of the disease in order to protect brain function and minimize serious damage to the brain. However, it is important to note that for patients who have been in the hospital for more than 6 h, it is still important to treat them as soon as possible. The earlier the treatment, the less brain damage will be caused, and the more it will help the patient to recover. Therefore, once you find a brain hemorrhage, you should go to a regular hospital in time to avoid delaying the condition.
