Changing patterns of posttraumatic acute renal failure.

ARF will continue to occur as more severely traumatized patients survive with better resuscitation. The incidence of ARF, however, appears to be steadily decreasing and ARF occurs only in patients with severe injury and multiple organ failure. ARF developing for the past three years in MIEMS was a nonoliguric variety in the majority of patients. Management of ORF with dialysis has been disappointing. Prevention of oliguria in ARF appears possible and may be one of the most important steps to decrease the morbidity and fatality rate. Further investigation is required to find the cause and optimum management of NORF.
