Which three conditions comprise the lethal triad in trauma resuscitation?

The lethal triad in trauma resuscitation is made up of hypothermia, acidosis, and coagulopathy. Each one feeds the others in a dangerous loop: hypothermia slows the coagulation cascade and impairs platelet function, making bleeding worse; bleeding and poor perfusion cause lactic acidosis, which further reduces coagulation factor activity and platelet function; and coagulopathy leads to more bleeding, which worsens both hypothermia and acidosis through ongoing blood loss and dilution. This cycle is hard to reverse unless all three components are addressed together—by limiting warming loss, actively warming the patient, and using balanced transfusion strategies to restore coagulation factors and platelets while improving perfusion. Other findings like hypoxia, thrombocytopenia, or anemia can accompany trauma but are not the defining trio.
