Blood purification for crush syndrome.
At least 372 people developed crush syndrome after they were injured by the Great Hanshin-Awaji Earthquake. Of these, 23 were transferred to Osaka City General Hospital from the disaster area. The serum creatinine kinase (CK) of each of the 23 patients exceeded 10,000 IU/L. Sixteen of these patients were treated with various methods of blood purification including hemodialysis (HD), plasma exchange (PE), and continuous hemodiafiltration (CHDF). The effectiveness on each method of blood purification was evaluated in this study based on the clearance of myoglobin and the length of time until recovery from acute renal failure (ARF). None of the patients died, and none suffered from ARF longer than 2 months. The length of time required for blood purification was significantly correlated with the serum CK and myoglobin levels on admission. The serum myoglobin levels decreased linearly regardless of the method of blood purification used. Our findings showed that the severity of ARF that occurred in association with crush injury was proportional to the amount of crushed muscle and that once ARF had developed, the clearance of myoglobin was not affected by any of the blood purification methods tested including HD, PE, and CHDF. Therefore, the method of blood purification employed for crush syndrome should be selected for its effectiveness in treating ARF, rather than the elimination of myoglobin.
