Surgery should be performed as soon as possible after complete cessation of bleeding to minimize secondary damage to surrounding brain tissue such as ischemic degenerative necrotizing edema. Hematoma expansion mostly occurs within 6 hours, especially within 3 hours. A large number of studies have proved that bleeding basically stops after 6 hours after hypertensive cerebral hemorrhage, so 6 hours often acts as the time limit for early surgery, but secondary brain damage starts to occur 6 hours after bleeding, and the later the surgery, the heavier the peripheral damage and the worse the functional recovery, weighing the pros and cons, most people advocate that surgery is appropriate 6-12 hours after the onset. Drilling and drainage: generally used for not too much bleeding (because the flow rate of drilling and drainage is small, if the hematoma is large and the flow rate of drilling and drainage is too small to achieve the purpose of decompression), the location of deeper part or important functional area, the surgery is less traumatic, but can not effectively stop bleeding, so the recurrence rate is higher; open hematoma removal: used for more heavy bleeding, the location of shallow relatively non-important functional area, the surgery is traumatic, but can find the bleeding point and stop bleeding, and can clearly diagnose whether the AVM is serious or not. And it can clearly diagnose whether it is AVM and other lesions, so the recurrence rate is low. At present, there is no uniformity in the dosage of UK or rt-PA in the postoperative drainage tube, the time of closing the tube, and the frequency of drug injection. Since brain hemorrhage surgery is mainly to preserve life rather than function, the priority is to stop bleeding and relieve compression, and the priority is to preserve life.
