If a newborn has a simple subarachnoid hemorrhage with no other complications, he does not need surgery, but only a drug infusion to improve the condition. If there is a combination of cerebral vasospasm, cerebral edema, etc., it is possible that the time will be delayed by 1-2 weeks. However, if the subarachnoid hemorrhage is combined with cerebral hemorrhage due to certain factors, or even requires open surgery, the recovery time may be very long, and the more severe the condition is, the more often the child will have hemiplegia, or immobility of the limbs, and will need to do the corresponding rehabilitation exercises later. It may take up to 3 months to improve. For neonatal subarachnoid hemorrhage, it is important to detect and treat it early to reduce the occurrence of complications.
