Air can get trapped under the skin, a condition known as subcutaneous emphysema, through several ways. It's important to note that this is a relatively rare condition.
Common Causes of Air Under the Skin
Here's a breakdown of how air can find its way beneath the skin's surface:
Trauma and Injury
- Penetrating Wounds: Injuries that break the skin, such as stab wounds or deep cuts, can allow air to enter the tissue underneath.
- Blunt Trauma: Significant impact from events like car accidents can damage internal structures, potentially forcing air into subcutaneous spaces.
- Fractures: Broken bones, particularly rib fractures, can sometimes cause air to leak from the lungs or airways into nearby tissues.
Infection
- Gas-Producing Bacteria: Certain types of infections, especially those involving bacteria that produce gas, can lead to air accumulation under the skin. This is commonly associated with severe infections that can cause other complications if not treated immediately.
Medical Procedures
- Surgical Procedures: Some surgical interventions, particularly those involving the chest or lungs, can inadvertently introduce air into subcutaneous tissue.
- Endoscopy: Procedures involving the insertion of a scope, particularly in the upper respiratory tract, can sometimes result in air leaking out and becoming trapped under the skin.
- Certain Injections: If air is inadvertently introduced during injections, it can cause localized subcutaneous emphysema.
Characteristics and Medical Terminology
Subcutaneous emphysema is a medical term that refers to the condition where air is trapped in the tissues beneath the skin. Doctors also sometimes use terms like crepitus, tissue emphysema, or subcutaneous air when talking about this. This condition can be detected when the affected skin area feels like bubble wrap and sometimes makes a crackling sound.
| Cause | Description |
|---|---|
| Trauma/Injury | Wounds, impact, or fractures that allow air to enter. |
| Infection | Certain bacteria produce gas, leading to air trapped under the skin. |
| Medical Procedures | Surgical interventions, endoscopic procedures, or certain injections can sometimes introduce air. |
In summary, while subcutaneous emphysema can be concerning, knowing how it occurs can help understand potential risks and the importance of seeking medical attention.
