@wesley91- I have worked as an emergency room nurse for 12 years and see these types of cases quite often.
Most medical emergencies that would require a chest tube placement are things such as a pneumothorax, hemothorax, or a hemo-pneumo thorax.
In a pneumothorax, there is a collection of air in the pleural space. This doesn’t necessarily have to be from a traumatic event. There have been several cases that I have seen where the person just had a collapsed lung, leading to a pneumothorax, and had not had an injury. However, most of the time, a pneumothorax is secondary to some type of trauma to the chest area.
A hemothorax is blood, instead of air, in the pleural space. This is usually from a traumatic injury or post-surgery.
In these cases, a trocar chest tube would need to be inserted immediately to aspirate the air or blood. The hospital that I work for prefers to use the trocar rather than the other types.
