颅内血肿微创术后单纯液化引流与冲洗后液化引流对术后再出血的影响

The influence of the pure liquefaction diversion and rinse liquefaction drainage on the re-bleeding after the operation of intracraniai haematoma minimally invasive surgery

目的探讨颅内血肿微创术后不同引流方法对术后再出血的影响。方法将颅内血肿微创术后进行血凝块引流的患者分为A、B两组，A组单纯应用血凝块液化剂（尿激酶加玻璃酸酶）液化血凝块引流而不行冲洗步骤，B组以0．9％氯化钠注射液反复冲洗血肿后应用血凝块液化剂（同上）液化引流。结果A组血肿清除率与B组相当，而A组再出血发生率（3．8％）明显低于B组（22．7％）（x2=4．594，P〈0．05）。结论颅内血肿微创术后多数患者单纯使用液化剂就能很好弓I流血肿，且再出血风险明显降低。

Objective To explore the different effects on the bleeding after the surgery of minimally invasive intracranial haematoma with drainage method. Methods The cases with minimally haematoma invasive operation were divided into A and B group. Group A simply used the liquefaction agent for blood clots（ urokinase mixed with hy- aluronidase）, without washing step, and Group B used saline water to wash repeatedly and then use liquefaction agent to divert. Results The hematoma clearance rate of A group equal to that of B Group, while the rate of re-bleeding was （3.8 % ） obviously lower than than of B Group（22.7 % ） （ X2 = 4. 594, P 〈 O. 05）. Conclusion For many cases who have experienced the minimally invasive intracranial operation, the simple use of liquefaction agent can divert haema- toma,and the risky rate of re-bleeding was obviously lowered.
