The probability of surviving a brain hemorrhage in the ICU is about 33%, but the patient’s status prior to surgery should be evaluated on a case-by-case basis, especially if the patient has bilateral dilated pupils, respiratory and circulatory failure, and needs to maintain blood pressure and respiration by means of a ventilator and antihypertensive drugs. The signs of death may appear in a day or two. If the patient is comatose before the surgery, the pupils are dilated for a very short period of time, the corresponding surgical treatment is taken in time, the surgery goes smoothly, and no complications occur after the surgery, but it is difficult to withdraw the tube after the surgery, and it is not possible to restore the autonomic breathing in time, the chance of such a patient being rescued in the ICU is very high, and it can even reach more than 80%, depending on the specific changes of the condition at that time.
