What are mast trousers used for in hypovolemic shock?

Mast trousers, also known as anti-shock garments, are designed to treat hypovolemic shock by applying external pressure to the body, particularly to the lower extremities. The main purpose of these trousers is to force blood centrally towards the vital organs such as the heart and brain. In hypovolemic shock, there is a significant reduction in blood volume, which can lead to inadequate perfusion of these critical areas.

By compressing the lower half of the body, mast trousers help to redistribute blood volume temporarily, improving central circulation and enhancing perfusion to vital organs. This intervention can be crucial in stabilizing a patient while more definitive treatments, like fluid resuscitation, are implemented.

Other options do not accurately reflect the function of mast trousers. They are not used to induce hypothermia, provide analgesia, or directly elevate blood pressure. Instead, their focus is on optimizing blood flow to critical regions during a state of compromised circulation due to low blood volume.
