METHODS： Pre-operative preparation was improved by analyzing pathological factors and hematoma property, and considering patients＇ age, basic disease, blood pressure control, with persistent haemorrhagia/rehaemorrhagia or not, operative occasion choice, positioning and other procedures. In the surgery, positioner was used. Initial aspiration volume was cautiously controlled. After operation, vital signs of patients were kept stable by cautiously using hematoma liquefacient and combining with free radical scavenger. RESULTS： The core content of individual micro-invasive surgery was mainly to relieve intracranial pressure. Under the condition of sufficient pre-operative preparation known by patients＇ family members, precise positioning was determined and individual therapeutic regimen was made. Meanwhile, caution should be taken in hematoma aspiration. Liquefaction and drainage should be paid more attention, and complications were processed actively. CONCLUSION： During the process of micro-invasive evacuation of intracranial hematoma for treating cerebral hemorrhage, attention should be paid to analyzing cerebral hematoma etiology and pathophysiological mechanism, and individual idea should be considered in surgical treatment aiming at patients＇ concrete disease condition.展开更多
