Points & Pearls Excerpt
-
In prehospital trauma care, there is no imperative for endotracheal intubation over bag-valve mask ventilation.
-
Prehospital crystalloid fluid administration should be enough only to maintain mentation and pulses; resuscitation should instead proceed with blood or plasma, which have shown mortality benefits in selected prehospital settings.
-
Stratification by the degree of shock index may predict outcomes better than the traditional ATLS® classes of shock.
-
A delta shock index value of > 0.1 is linked to greater mortality, blood transfusion, and intensive care unit (ICU) length of stay.
