Sucking Chest Wounds

Post by Ryan » Fri Mar 30, 2012 11:05 am

Sucking chest wounds. Penetrating chest trauma. What are they? Fucking bad news.

The two pleura layers around the lungs press up against one another, and in the healthy chest, there is no air or significant fluid between them. The space between these two layers of pleura is called the pleural space.

There are some main categories of SCW's:

Pneumothorax's

A pneumothorax occurs when air enters the pleural space. This will cause a partial or absolute collapse of a lung. This usually occurs in a tactical setting from a traumatic injury (traumatic pneumothorax) e.g. a penetrating chest wall injury such as a stab or gunshot wound or a rib fracture. The pneumothorax can then be classified as either open or closed.

They will also be subdivided into left or right, complete or partial. For instance, "A left side, partial, closed pneumothorax".

Closed Pneumothorax

There is no associated external wound. The most common form of a closed pneumothorax is a spontaneous pneumothorax - this can be caused by anything from an injury sustained during mechanical ventilation, a broken rib or during an insertion of a central venous catheter. Tends to be associated with a flailed chest.

Open Pneumothorax

This occurs when the air is entering through an actual opening within the chest wall such as a hole or cavity a gunshot wound has created.

It is good to mention that any type of injury of this severity may cause what is known as a tension pneumothorax.

Tension Pneumothorax

A rapid accumulation of air in the pleural space causes high intrapleural pressures which resonate pressure upon the heart and great vessels, this is potentially life threatening.

An example.

They are managed by the insertion of a chest tube or needle for chest decompression (possibly with an underwater sealed drain (UWSD).

IF the puncture is too medial, it may pierce the heart or great vessel.

Haemothorax's

An accumulation of blood in the intrapleural space. It is often associated with an open pneumothorax and is then called a haemopneumothorax (as below).

Haemopneumothorax's

Blood and air has accumulated within the intrapleural space due to an open pneumothorax.

Diagnosis is done via immediate history and an examination. Chest X-ray is not for a tactical setting (LOL!).
