Response to delayed fluid therapy in crush syndrome.

BACKGROUND Although early treatment is valuable in the prognosis of crush syndrome, the diagnosis and treatment of many victims are inevitably delayed in major disasters. PATIENTS AND METHODS Among the 38 victims of the Marmara earthquake with crush injury, 27 were diagnosed as crush syndrome on the basis of findings of acute renal failure. Intensive intravenous fluid treatment was started in all patients on admission. Of these 27 patients, 10 required dialysis treatment while 17 did not. The laboratory data on admission were evaluated and compared between the two groups. RESULTS The mean admission time of 27 patients was 46.5 +/- (SE) 3.08 h. There was no significant difference between the dialysis and the nondialysis groups with regard to patient's age, trapped time or admission time. A significantly higher number of patients had crush injury in more than one extremity in the dialysis group. The dialysis group had significantly lower systolic blood pressure, central venous pressure but a higher heart rate together with higher levels of serum urea nitrogen, creatinine, creatinine kinase, C-reactive protein, fibrinogen on admission compared to the nondialysis group. CONCLUSION Our results suggest that even delayed application of aggressive specific fluid treatment under close monitoring may prevent the development of established acute renal failure.
