What is the principle of resuscitation in hemorrhagic shock encountered in the field?

• A. Aggressive fluid resuscitation to normal BP
• B. Delayed hemorrhage control until stable
• C. Early use of vasopressors
• D. Control hemorrhage first, provide warmed IV fluids as needed, and avoid over-resuscitation to prevent exacerbating bleeding

Answer: (D)

The idea being tested is damage-control resuscitation: the priority is to stop the bleeding first and protect the patient from the chain reaction that can come with ongoing hemorrhage. In the field, that means directly controlling the hemorrhage as soon as possible, while providing warmed IV fluids only as needed to maintain perfusion. Importantly, avoid over-resuscitation that can raise blood pressure before the source is controlled, because higher pressure can dislodge clots and worsen bleeding. Keeping the patient warm helps prevent hypothermia, which worsens coagulopathy, and if available, using blood products rather than large volumes of crystalloids supports clotting. Vasopressors aren’t the main tool here because they don’t stop bleeding and can compromise tissue perfusion without addressing the bleed.
