Shock And Resuscitation Topics

At a Glance

Focus on shock categories, pressor choices, perfusion markers, and reassessment after resuscitation.

Classify shockDifferentiate hemorrhagic, distributive, cardiogenic, obstructive, and mixed shock physiology.

Treat hemorrhage first in trauma.
Trend lactate and urine output.
Use bedside echo when available.

VasopressorsUse pressors as physiology-directed support while source control, volume, or cardiac interventions are addressed.

Do not let pressors hide bleeding.
Reassess endpoints frequently.
Confirm central access when needed.
