Damage control resuscitation:
Correct Answer: C
Rationale: Damage control resuscitation (DCR) mitigates trauma's lethal triad (hypothermia, acidosis, coagulopathy). It's indicated preemptively in severe bleeding, not just post-derangement, to prevent physiologic collapse. It begins pre-hospital (e.g., paramedics), not only in-hospital, using blood products early. Fluid restriction in hypotensive bleeding limits dilutional coagulopathy, favoring permissive hypotension until haemostasis crucial in uncontrolled haemorrhage. Radial pulse palpation gauges perfusion broadly, but head injury patients need cerebral perfusion pressure prioritization, not DCR adequacy. ABC remains foundational. Fluid restriction's role balancing shock correction with bleeding exacerbation defines DCR's shift from crystalloid overload, improving survival in exsanguinating trauma.
