What immediate action should be taken in the case of suspension trauma?

In the case of suspension trauma, the most critical immediate action is to get the patient to a horizontal position. This is essential because when a person is suspended, especially if they are hanging in a harness, the blood flow can become compromised, leading to a dangerous condition where blood pools in the lower extremities. By placing the individual horizontally, you help to stabilize blood circulation and reduce the risk of serious complications, such as fainting or loss of consciousness due to inadequate blood flow to the brain.

Repositioning the patient standing would not be advisable as it could exacerbate the condition by causing pooling of blood in the legs and increasing the risk of cardiovascular issues. Applying pressure to the legs or using cold packs does not address the urgent need to stabilize the patient's position, and these actions could potentially complicate the situation further rather than alleviating the risks associated with suspension trauma. Therefore, placing the patient flat on their back is the most effective and immediate response.
