Types: hypovolemic (hemorrhagic), distributive (septic, neurogenic), cardiogenic, obstructive. Initial approach: ATLS (Airway with C‑spine, Breathing, Circulation, Disability, Exposure). Hemorrhagic shock is most common in trauma; control bleeding + balanced transfusion (1:1:1) + permissive hypotension until hemorrhage control (except TBI). Resuscitation targets: lactate clearance, base deficit, urine output, MAP appropriate to context. Adjuncts: TXA within 3 hours of injury; damage control surgery principles. Orthopaedic hemorrhage control: pelvic binder, traction for femoral shaft, external fixation, tourniquet in limb exsanguination. Endpoints: normalization of mentation, MAP, lactate/base deficit clearance, warm peripheries, adequate urine output.
