对４７人次超早期脑内血肿单纯抽吸术实施时机与对血肿清除程度作回顾分析，结果发现在病程６小时内，平均抽成率为６３．１％，６～１２小时者为３８．２％，１２～１８小时者为１８．６％，１８～２４小时者为１０．９％，而在２４～４８小时者为９．５％。表明该疗法实施得越早对血肿清除的效果越好。而病程超过１８小时，其效果则较差。作者进一步探讨其原因，认为血液的凝固状态是影响抽吸效果的主要因素 47 cases of ultra-early intracerebral hematoma aspiration and the timing of the removal of hematoma for retrospective analysis showed that within 6 hours of the disease, the average rate of 63.1% aspirations, 6 to 12 hours was 38.2 %, 18.6% in 12-18 hours, 10.9% in 18-24 hours, and 9.5% in 24-48 hours. Indicating that the earlier the therapy is implemented, the better the effect of hematoma clearance. The duration of more than 18 hours, the effect is poor. The authors further explore the reasons for that the blood clotting state is the main factor affecting the suction effect
