Tourniquet Application Guidelines

Recommended Duration and Considerations

• The DOD Joint Trauma System guidelines recommend that tourniquets should be left in place until surgical control of bleeding is achieved, with the time to removal shortened as much as possible 1, 2, 3
• Some publications suggest a maximum application time of two hours, though military reports document cases where tourniquets remained in place for up to six hours with survival of the extremity 1, 2, 6
• The time to removal should be shortened as much as possible to minimize complications 4, 5

Potential Complications of Prolonged Tourniquet Use

• Improper or prolonged placement can lead to complications such as nerve paralysis and limb ischemia, which are relatively rare 1, 2, 5, 6
• The risk of complications from tourniquet use, including nerve paralysis and limb ischemia, should be considered when applying a tourniquet 1, 2

Clinical Application

• Tourniquets should be properly applied to completely control hemorrhage, with commercially available tourniquets being superior to improvised ones 4, 5, 7
