高血压脑出血术后二次脑损伤因素与脑组织氧及预后的关系研究

Study on the Correlation of Secondary Brain Insult with Brain Tissue Oxygen and Prognosis in Postoperative Patients with Hypertensive Intracerebral Hemorrhage

目的研究高血压脑出血术后合并二次脑损伤因素对患者脑组织氧及预后的影响。方法对2006年1月-2013年6月收治的120例高血压脑出血患者行手术治疗,术后对影响二次脑损伤的血压、体温、动脉血氧分压、血糖、血钠等多项指标进行监测,其中10例同时行脑组织氧监测,将患者按是否存在二次脑损伤因素分为阳性组和阴性组,并比较两组术后格拉斯哥预后分级。结果 73例阳性组患者格拉斯哥预后分级为Ⅴ级13例,Ⅳ级23例,Ⅲ级11例,Ⅱ级0例,Ⅰ级26例;47例阴性组分级为Ⅴ级19例,Ⅳ级16例,Ⅲ级4例,Ⅱ级2例,Ⅰ级6例;阳性组预后差于阴性组,差异有统计学意义(Z=-3.241,P=0.001)。脑组织氧监测显示脑灌注压、动脉血氧分压均与脑组织氧分压呈正相关(P<0.001)。结论二次脑损伤因素的异常改变,影响患者的脑组织氧代谢,可造成二次脑损害,继而影响预后。

Objective To study the brain tissue oxygen and prognosis index of the postoperative patients with hypertensive intracerebral hemorrhage （HICH） associated with secondary brain insults. Methods A total of 120 patients with HICH from January 2006 to June 2013 were treated by neurosurgical intervention. Postoperative monitoring of factors affecting the secondary brain insults in the 120 patients and of brain tissue oxygen in 10 patients was performed and statistically analysis was carried out. Results Secondary brain insults had a significant influence on the prognosis of postoperative patients with hypertensive intracerebral hemorrhage, and was correlated with brain tissue oxygen metabolism. Conclusion Abnormal secondary brain insults affect brain tissue oxygen metabolism, which may further deteriorate the brain damage and can lead to poor prognosis.
