外伤性基底节血肿预后影响因素的Logstic模型分析

目的探讨影响外伤性基底节血肿预后的相关因素。方法对32例连续病例进行研究，记录年龄、性别、致伤原因、GCS评分、瞳孔大小变化、基底节血肿量、中线移位程度、血肿是否破入脑室及是否有其它颅内血肿等9个变量。6个月后按照预后评分将病例分为预后良好组与预后不良组。利用Logistic回归模型筛选有统计学意义的预后影响因素。结果通过逐步Logistic回归分析发现，是否合并其它颅内血肿和瞳孔大小变化是影响外伤性基底节血肿预后的独立危险因素。模型预测成功率达到87．5％。结论对于早期出现瞳孔改变或合并颅内其它部位出血的患者，应加强监护，必要时早期采取手术治疗。

Prognostic Factors of Traumatic Basal Ganglia Hematoma: a Logistic Regression Analysis

Objective To investigate the prognostic risk factors of traumatic basal ganglia hematoma (TBGH). Methods Nine parameters, including age, sex, the cause of injury, GCS, pupillary changes, Hematoma volume, midline shift, TBGH ruptured into ventricle or not, having the other intracranial hematoma or not, were recorded in 32 consecutive patients with TBGH. All the patients were divided into both the good outcome and bad outcome groups according to GOS 6 months after the trauma. The relationship of prognosis to the above-methioned 9 parameters were analysed by using computerized logistic model. Results Having the other intracranial hematoma and pupillary change were independent risk factors for the prognosis of patients with TBGH. The prognosis predicted by the model was right in 87.5% of the patients with TBGH. Conclusion The patients with TBGH which is accompanied papillary change or the other intracranial hematoma in early stage should be strictly monitored or operated on in good time.
