antishock garment

antishock garment

A three-compartment garment that can be placed quickly on a patient with severe hypovolemia or a suspected pelvic fracture. When the compartments are inflated, they compress the abdomen and legs, limiting the blood flow into these areas and preventing pooling of blood and fluid in the underlying tissues. The value of the device in improving long-term survival has been questioned; therefore, these garments are no longer used as frequently as they were in the past. Also known as MAST (military antishock trousers). Synonym: pneumatic antishock garment


The garment is contraindicated in cardiogenic shock, penetrating abdominal or chest trauma with hemorrhage, or congestive heart failure. In patients who are bleeding as a result of penetrating trauma, the pressure in the garment may raise systemic vascular resistance (SVR) and increase the rate and volume of blood loss.

Patient care

Inflatable compartments are filled to appropriate pressure (approx. 104 mm Hg or until the pop-off valves begin to leak), from the bottom up, and inflation is maintained until venous access and fluid resuscitation are initiated. Compartments are then deflated from top to bottom; the patient's blood pressure and pulse are monitored frequently for evidence of hypotension. See: anti-G suit
