The management of external sources of hemorrhage during the primary survey prioritizes immediate and effective measures to control bleeding to stabilize the patient. Using manual pressure or a tourniquet is crucial as these methods aim to restrict blood flow to the area of injury and halt significant blood loss, which is vital for the immediate preservation of life.

Manual pressure applies direct force to the wound, promoting clot formation and reducing blood flow. When direct pressure is insufficient, especially in cases of severe extremity hemorrhaging, a tourniquet may be indicated. Tourniquets are effective for controlling extremity bleeding by compressing the blood vessels beyond the injury site, making them an essential tool in trauma care.

Other management options, such as IV fluids, surgical intervention, or the administration of anticoagulants, serve different purposes and are not the immediate priorities during the primary survey focused on addressing life-threatening situations. IV fluids are useful for volume resuscitation after bleeding is controlled. Surgical intervention may be necessary later on, but it cannot directly address external hemorrhage in the critical early moments. Administering anticoagulants could exacerbate bleeding and is not appropriate in the acute management of hemorrhage.
