目的探讨自发性脑内出血(ICH)患者发病4h内的首诊CT对早期血肿扩大的预测作用。方法本组98例患者均由发病后4h内CT诊断为ICH,24h后复查CT,以了解血肿扩大的发生情况。先将可能的危险因素与血肿扩大之间进行显著性检验,再用Logistic回归加以明确,得到回归方程。结果早期血肿扩大的发生率为26.5%。根据影响力大小,首诊CT早期血肿扩大的预测指标依次是血肿密度不均和首诊CT距发病的时间(IOFC)。结论首诊CT对ICH早期血肿扩大具有明确的预测作用。血肿密度不均和IOFC是早期血肿扩大的预测指标。
Objective To investigate the predictive value of initial diagnosis of CT in the early stage of hematoma enlargement within 4 hours after onset of spontaneous intracerebral hemorrhage (ICH). Methods 98 patients in this group were diagnosed as ICH by CT within 4 hours after onset and CT after 24 hours to find out the occurrence of hematoma enlargement. First, the possible risk factors and hematoma expansion between the significant test, and then use Logistic regression to be clear, the regression equation. Results The incidence of early hematoma enlargement was 26.5%. According to the size of the influence, the predictive indexes of hematoma enlargement in the first diagnosis of CT followed by the unevenness of hematoma density and the time of onset of the first diagnosis of CT (IOFC). Conclusions The first diagnosis of CT has a clear predictive effect on the early expansion of hematoma in ICH. Uneven density of hematomas and IOFC are predictors of early hematoma enlargement.
