Background: Oxidative damage and increasing of lipid peroxidation are caused by chronic iron overload in patients with beta thalassemia major. Fatty acids are important structural elements for palmitoylation of membrane proteins which constitute a great part of natural membranes. Oxidative damages caused by reactive oxygen derives in thalassemic erythrocytes can be determined with lipid peroxidation, protein oxidation, and antioxidant system elements.

Perineal wounds caused by high-kinetic-energy shotgun blasts have a high mortality risk because they are often accompanied by injuries of the anus, rectum, genitourinary system, and extremities. Mortality often results from hemorrhage in the early stage and from multiple organ failure caused by sepsis in the late stage. The primary step in the treatment of patients presenting with perineal wound and hemodynamic instability caused by severe hemorrhage is to control hemorrhage and contamination using damage control surgery.

Background: Transport of casualties from a combat area to a fully equipped hospital where all techniques of damage control surgery (DCS) can be performed requires a great deal of time. Therefore, prior to transport, prompt control of hemorrhage and contamination should be achieved, and resuscitative procedures should be performed at the nearest health center. The aim of the present study was to investigate the effect of the location at which DCS was performed on rates of mortality.
