Shock & Hemodynamics
Shock categories, vasopressor selection, perfusion markers, and bedside reassessment.
Classify shock
Differentiate hemorrhagic, distributive, cardiogenic, obstructive, and mixed shock physiology.
- Treat hemorrhage first in trauma.
- Trend lactate and urine output.
- Use bedside echo when available.
Vasopressors
Use 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.
