CAUSES ANALYSIS AND PREVENTION OF REBLEEDING IN SUBARACHNOID HEMORRHAGE

[Objective]To explore the risk factors and causative factors of rebleeding in subarachnoid hemorrhage.[Methods]78 patients who survived the subarachnoid hemorrhage were followed up for 6 months after the bleeding.The risk factors were compared between the two groups of 31 cases with rebleeding(rebleeding group),and 47 cases without rebleeding(control group).[Results]The rebleeding rate of the 78 patients was 39.7%.The percentage of which patients had the risk factors of being over 60,grade Ⅲ and above of Hunt-Hess grade,hypertension,aneurysm,admission over 24 hours after the first attack in the rebleeding group was higher than that in the control group.[Conclusion]Being over 60 years old,grade Ⅲ and above of Hunt-Hess grade,hypertension,aneurysm,admission over 24 hours after the first attack are the risk factors of rebleeding in subarachnoid hemorrhage.The prevention of rebleeding is to control the risk factors and avoid the causative factors.
