MB and rhabdomyolysis: EHS is significantly different from massive crush syndrome, due to involving heat injury factors, the myoglobin released from rhabdomyolysis caused by EHS increases gradually, usually without serious trauma and extrusion, but hypermyoglobinemia can aggravate the injury of other organs, and its treatment methods are also different.[7,8] Studies have shown that serum myoglobin exceeds the renal threshold of 0.5–1.5 mg/dL; hence myoglobinuria will occur.
