Intrapleural instillation of streptokinase. Effects on systemic fibrinolysis.
Ten consecutive patients aged 25 to 75 with postoperative empyema or hemothorax conventionally treated with drainage without sufficient effect were given intrapleural instillations of streptokinase (Kabikinase, 250,000 IE) for 4 hours). The effects on systemic fibrinolysis were studied. Venous blood samples for determination of fibrinolytic activity on fibrin plates, plasminogen, alpha 2-antiplasmin, alpha 2-macroglobulin, fibrinogen, fibrin(ogen) degradation products (FDP) and thrombin time were taken before instillation, after instillation and then after 24 hours. Preinstillation values were compared to the values 4 and 24 hours after instillation with Student's paired t-test. There were no differences in fibrinolytic activity, alpha 2-macroglobulin and thrombin time. There was a slight increase in plasminogen, alpha 2-antiplasmin and fibrinogen, probably due to an acute phase reaction. Fibrin degradation products showed an increase with border line significance. These changes are not consistent with generalized fibrinolysis, and it is concluded that intrapleural instillations of streptokinase can be given safely in the early posttraumatic or postoperative period.
