MAST suit update.

In recent years, the use of the MAST suit has become commonplace. While no controlled human studies have shown the device's efficacy, extensive clinical experience suggests that it is practical and useful in combating shock, stabilizing fractures, and promoting hemostasis. Studies indicate that the antishock trousers elevate blood pressure primarily by increasing peripheral vascular resistance. Proper application and removal of the device are crucial. A number of potential complications exist, but are infrequent and rarely should preclude MAST suit use. Further studies are necessary to prove the efficacy of the device and clearly define its role in patient management.
