Suspension trauma

A condition caused by prolonged suspension in a harness

Suspension trauma, also known as harness hang syndrome, is a medical condition that can occur when a person is suspended in a harness for an extended period. This condition can lead to serious health consequences, including loss of consciousness and even death, if not addressed promptly.

Pathophysiology

Suspension trauma occurs when a person is suspended in a harness and remains immobile for a prolonged period. The harness can restrict blood flow, particularly in the legs, leading to venous pooling. This pooling of blood can cause a decrease in venous return to the heart, resulting in reduced cardiac output and potentially leading to syncope or cardiac arrest.

Symptoms

The symptoms of suspension trauma can vary but often include:

• Lightheadedness
• Nausea
• Dizziness
• Sweating
• Palpitations
• Loss of consciousness

Prevention

Preventing suspension trauma involves ensuring that individuals using harnesses are trained in proper techniques and are aware of the risks. Regular safety training and the use of fall arrest systems can help mitigate these risks. It is also important to have a rescue plan in place to quickly assist anyone who may become suspended.

Management

If a person is suspected of experiencing suspension trauma, it is crucial to remove them from the harness as quickly and safely as possible. Once on the ground, the individual should be laid flat and monitored for signs of shock or other complications. Medical attention should be sought immediately.

Occupational Risks

Falls are a significant risk in occupations such as oil and gas extraction.

Suspension trauma is a particular concern in occupations where workers are required to use harnesses, such as construction, oil and gas extraction, and rock climbing. In these fields, falls are a common hazard, and the use of harnesses is essential for safety. However, the risk of suspension trauma must be managed through proper training and equipment.
