Study on the risk factors of hematoma enlargement in patients with intracerebral hemorrhage at acute stage

Objective To investigate the related risk factors referred to hematoma enlargement in acute stage of spontaneous cerebral hemorrhage.Methods 104 stroke patients were divided into the observation group(hematoma enlarged group) and control group (without hematoma enlarged group).The course of disease,mean arterial pressure,the bleeding amount of the first time,hematoma shape and mortality were compared between the two groups,and the risk factors of hematoma enlargement of cerebral hemorrhage patients were analyzed.Results (1) The course of disease,mean arterial pressure,hematoma shape and the bleeding amount were significantly different between the two groups(t =9.5431,11.4499,6.1847,10.7233,all P ＜ 0.05).(2) The multivariate logistic regression analysis showed that factors of influence on hematoma enlargement were mean arterial blood pressure,the course of disease and hematoma shape.(3)The mortality of the observation group was 36.53 ％,which was significantly higher than that of the control group (19.23 ％) (χ2 =3.8731,P ＜ 0.05).Conclusion High level of mean arterial blood pressure,short time of interval to onset,irregular shape of hematoma and frequent vomiting are main risk factors of hematoma enlargement in patients with intracerebral hemorrhage at acute stage.
