Clinical analysis hematoma enlargement after intracerebral hemorrhage

Objective To discuss the dangerous factors for hematoma enlargement after intracerebral hemorrhage(ICH).Methods We selected 313 patients with ICH admitted within 24h after onset.According to the CT result,all 313 patients were divided into hematoma enlargement group and non-hematoma enlargement group.Statistical analysis was performed to assess the relationships between hematoma enlargement and BP,usage of mannitol,the fature of the hematoma and the moving history.Results Patients with SBP200mmHg and DBP110mmHg in hematoma enlargement group were more than those in non-hematoma enlargement group(P0.01).Patients with early usage of mannitol(≤6h) of hematoma enlargement group were significantly more than those of non-hematoma enlargement group(P0.01).Thalamic hemorrhage of hematoma enlargement group was significantly more than non-hematoma enlargement group(P0.05).The ratio of bleeding volume20ml was significantly higher in hematoma enlargement group than non-hematoma enlargement group(P0.01).Hematoma with irregular shape were more prone to hematoma enlargement(P0.01).There were 57.98% of patients had moving history in the hematoma enlargement group,while 41.75% in the non-hematoma enlargement group,with significant differences(P0.05).Conclusion High blood pressure,usage of mannitol earlier(within 6h),thalamic hemorrhage,bleeding volume20ml,hematoma with irregular shape and moving history were all risk factors for hematoma enlargement.
