40％以上的肺炎患者可合并胸腔积液，其中约15％可继发感染，此时治疗需用手术引流，但由于纤维蛋白粘连阻隔，插管引流胸水常常失败。一些研究结果提示，胸腔注入链激酶可使胸膜内纤维蛋白粘连溶解而有利于胸腔积液的引流，但因没有设置对照研究，故难令人信服。本文报道对并? More than 40% of patients with pneumonia can be combined pleural effusion, about 15% of which can be secondary to infection, when the need for surgical drainage, but due to fibrin adhesion barrier, intubation drainage of pleural effusion often fail. Some studies suggest that intrathoracic injection of streptokinase fibrin adhesions can be pleural pleural effusion conducive to drainage, but not set up a controlled study, it is difficult to convince.
