What does subcutaneous emphysema sound like?
Subcutaneous emphysema has a characteristic crackling-feel to the touch, a sensation that has been described as similar to touching warm Rice Krispies. This sensation of air under the skin is known as subcutaneous crepitation, a form of Crepitus. Numerous etiologies of subcutaneous emphysema have been described.

- sore throat.
- neck pain.
- swelling of the chest and neck.
- difficulty breathing.
- difficulty swallowing.
- difficulty speaking.
- wheezing.
What is a subcutaneous emphysema?
Subcutaneous emphysema is the de novo generation or infiltration of air in the subcutaneous layer of skin. Skin is composed of the epidermis and dermis, with the subcutaneous tissue being beneath the dermis.
When does subcutaneous emphysema occur?
Subcutaneous emphysema (SE) occurs when air gets into the tissues under the skin and in the soft tissues. This usually occurs in the soft tissues of the chest wall or neck but can also occur in other parts of the body [1].
What is crepitus in the lungs?
Crepitus is the abnormal popping or crackling sound in either a joint or the lungs, which may be faint or loud enough for people to hear. It is often accompanied by a popping or crunching sensation that may sometimes be uncomfortable or painful.
What causes bubbles under skin?
subcutaneous emphysema, disorder in which bubbles of air become trapped under the skin. The condition can occur after surgery or traumatic accidents and can also develop locally in cases of gas gangrene. One of the frequent causes of subcutaneous emphysema is rupture of the lung tissue.
Is subcutaneous emphysema the same as emphysema?
Subcutaneous emphysema is a condition in which air becomes trapped under the skin. Emphysema simply means “air,” while “subcutaneous” refers to the location of the air. This type of emphysema is not like other types of emphysema you have heard of, which are diseases of the lungs, and it is not caused by smoking.
What is Paraseptal?
What Is Paraseptal Emphysema? Doctors also call it distal acinar emphysema. It mainly damages the tiny ducts that connect to your lung’s fragile air sacs that help you breathe. Paraseptal emphysema usually affects the upper parts of your lung. Fluid-filled sacs called bullae form on the organ’s surface.
What is the difference between crepitus and subcutaneous emphysema?
Subcutaneous emphysema can often be seen as a smooth bulging of the skin. When a health care provider feels (palpates) the skin, it produces an unusual crackling sensation (crepitus) as the gas is pushed through the tissue.
How is subcutaneous emphysema diagnosed?
Computed tomography (CT) scan can show dark pockets of air in the subcutaneous layer and may also be helpful in identifying the source of the air. Laryngoscopy and/or bronchoscopy may be performed if the subcutaneous emphysema is thought to be the result of an injury from intubation. Ultrasound.
How do you get rid of subcutaneous emphysema?
Several methods have been described in the literature for the treatment of extensive subcutaneous emphysema, including: emergency tracheostomy, multisite subcutaneous drainage, infraclavicular “blow holes” incisions and subcutaneous drains or simply increasing suction on an in situ chest drain.
What is the difference between crackles and Crepitations?
Crackles, still often referred to as “rales” in the United States and “crepitations” in Great Britain, consist of a series of short, explosive, nonmusical sounds that punctuate the underlying breath sound; fine crackles (Audio 16-4 ) are softer, shorter in duration, and higher in pitch than coarse crackles (Audio 16-5) …
Where does the air come from in subcutaneous emphysema?
Subcutaneous refers to the tissue beneath the skin, and emphysema refers to trapped air. Since the air generally comes from the chest cavity, subcutaneous emphysema usually occurs on the chest, neck and face, where it is able to travel from the chest cavity along the fascia.
What’s the difference between SCE and subcutaneous emphysema?
Subcutaneous emphysema. Subcutaneous emphysema ( SCE, SE) is when gas or air is in the layer under the skin. Subcutaneous refers to the tissue beneath the skin, and emphysema refers to trapped air. Since the air generally comes from the chest cavity, subcutaneous emphysema usually occurs on the chest, neck and face,…
How is subcutaneous emphysema caused in a car accident?
Subcutaneous emphysema is often found in car accident victims because of the force of the crash. Chest trauma, a major cause of subcutaneous emphysema, can cause air to enter the skin of the chest wall from the neck or lung.
Can a person be misdiagnosed with subcutaneous emphysema?
Edema from subcutaneous emphysema has been misdiagnosed as other conditions such as allergic reactions, but the presence of crepitus and the fact that there will be an absence of lip swelling with subcutaneous emphysema can help medical professionals to differentiate between these conditions.
