30 years old male patient presented to our emergency clinic with complaint of left upper quadrant pain. We learned there has been a fight, he was assaulted with fists and iron bricks to his abdomen and right arm. Clinical examination revealed echymotic areas in his thorax, back and right arm; tenderness at left upper quadrant of abdomen. In laboratuary tests creatinin phosphokinase (CPK), creatinin(Cr) and potassium(K) levels were high. The patient admitted to emergency service with diagnosis of rhabdomyolysis. We started izotonic saline infusion, sodium bicarbonate and furosemide treatment. His serum levels returned to normal values in the fourth day of his admission. In a trauma patient independent from extent of muscle damage if enzymes are high; a probability of acute tubuler necrosis risk is also high. In patients presented to emergency clinic due to trauma, without looking at the extent of muscle injury ; CPK, Cr, K levels must be seen, and if they are high , to prevent complications treatment must be started immediately.
