Epsilon-aminocaproic acid in traumatic renal hematuria in the rabbit.

Epsilon-aminocaproic acid (EACA) was intravenously administered to rabbits subjected to bilateral renal crushing trauma. Posttraumatic hematuria in 10 control rabbits lasted a mean of 5.5 days (range 5 to 7 days). Rabbits treated with 1250 mg 5 min before renal trauma and with repeat EACA injections 1 hr (500 mg) and 24 hr (500 mg) after the injury had significantly less hematuria. Only eight of 20 EACA-treated rabbits had any hematuria, and this bleeding terminated by the 2nd posttrauma day in all. EACA may have an important role in the management of trauma-induced renal bleeding.
