Puristusvamma

Puristusvamma, often referred to as crush injury in English, is a physical trauma resulting from prolonged or intense compression of the body. This compression can affect muscles, nerves, blood vessels, and even organs. The severity of a puristusvamma depends on the duration of the compression, the force applied, and the area of the body affected. Common causes include being trapped under heavy objects, such as in construction accidents or natural disasters, or prolonged compression in a confined space.

The immediate effects of a puristusvamma can include pain, swelling, and loss of sensation in the affected limb. As the compression continues, blood flow to the tissues is restricted, leading to oxygen deprivation and cell damage. Once the pressure is released, a significant complication known as rhabdomyolysis can occur. This is the breakdown of muscle tissue, releasing myoglobin into the bloodstream. High levels of myoglobin can overwhelm the kidneys and lead to acute kidney failure, a potentially life-threatening condition. Other complications can include compartment syndrome, where swelling within a muscle compartment restricts blood flow, and nerve damage.

Treatment for puristusvamma focuses on immediate medical attention to relieve the pressure, assess for internal injuries, and manage complications. This may involve surgical decompression, intravenous fluids to support kidney function, and pain management. Long-term rehabilitation is often necessary to regain strength and function in the affected areas. Prevention of puristusvamma involves safety precautions in environments where heavy objects or confined spaces are present.
