Which statement best describes why crystalloids are restricted early and balanced blood products are used in ATCN resuscitation?

• A. To maximize crystalloid infusion to improve perfusion
• B. To avoid transfusions entirely
• C. To limit crystalloids and use balanced blood products to minimize dilutional coagulopathy and edema
• D. To rely on crystalloids as the primary resuscitation fluid

Answer: (C)

In trauma resuscitation, the goal is to restore perfusion while preserving clotting function and avoiding fluid overload. Crystalloids given in large quantities quickly dilute coagulation factors and platelets, expand the interstitial space, and can lead to edema, including in the lungs, without reliably stopping ongoing hemorrhage. Balanced blood products deliver volume and, importantly, restore coagulation factors, fibrinogen, and platelets in ratios that support hemostasis and oxygen delivery. Using these products early helps prevent dilutional coagulopathy and reduces edema compared with heavy crystalloids, which is why this approach is favored in ATCN resuscitation. Other strategies that rely on large crystalloid infusions or avoid transfusions fail to address the bleeding and coagulopathy components of hemorrhagic shock.
