![]() ![]() When the skin thaws, pain and severe discomfort can occur in the affected area. However, if contact with the aerosol is prolonged the skin will freeze further and deeper layers of tissue will be affected, causing a more serious burn that reaches the dermis, destroys nerves, and increases the risk of infection and scarring. Most injuries of this type only affect the epidermis, the outermost layer of skin. Signs and symptoms An example of postinflammatory hypopigmentation (the light white patches) about one year after a severe aerosol burn.ĭepending on the duration of exposure aerosol-induced frostbite can vary in depth. ![]() In rare cases aerosol-induced burns can be severe enough to necessitate skin grafting. It is highly advised for those who develop frostbite to seek medical attention. The form of injury is freezing of the skin, a type of frostbite. According to controlled laboratory experiments, the gas from a typical deodorant spray can reduce skin temperature by up to sixty degrees Celsius. Uncontrolled cooling, however, can result in freeze burns to the skin. ![]() In freeze sprays, a controlled amount of this cooling is useful. Īdiabatic expansion and/or evaporative cooling (with a low boiling temperature) causes the gas to rapidly cool on exit from the aerosol applier. Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. If your burn has healed, you may also be given a compression glove.Medical condition aerosol frostbite of the skinĪn aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. Your therapist may bandage your hand with a stretchy bandage called ‘coban’ which helps to push the oedema out of the swollen area. You should avoid lying flat as this encourages fluid collection in your face and head which can lead to difficulty opening your eyes and may also affect your breathing. If you have facial swelling it is extremely important to maintain an upright position. Upright position (for face, head or neck burns) Please ask your therapist if you are unsure. Sometimes movement is not encouraged (e.g. Your therapist may show you specific exercises to help with this. Muscles act as a pump, pushing fluid away from the swollen area. Slings, pillows, tables and sometimes splints may be used to position your limb. The swollen part should be higher than the rest of the limb so that gravity can assist. ElevationĮlevation will encourage drainage of fluid and allow it to be reabsorbed by the body. There are steps that you can take to reduce the amount of swelling you have and to prevent it from getting worse. In this instance it is even more important to follow the advice below to minimise the negative effects of fluid. If you have had a skin graft, tissue fluid and bleeding can affect the healing and in some cases, may cause the graft to fail. Otherwise it can increase pain, make it difficult to move, cause stiffness or deformity of joints, interfere with the normal functioning of your muscles, nerves and blood vessels and can cause a superficial burn to deepen. It is very important that the swelling is reduced as soon as possible. The extent and location of the swelling will depend on how the burn was caused and the location and depth of the burn injury. Swelling tends to occur soon after injury and generally decreases after 48–72 hours, although this timescale can vary. The swelling is caused by fluid leaking from blood vessels and collecting around damaged areas. For example, if your burn is on your arm, then your hand can also become swollen, due to the effects of gravity. Why do I have oedema?ĭepending on the size of the burn, you may experience swelling immediately around the injured area or it may involve other parts of the body. This leaflet will help you understand why you may have oedema following your burn injury and give you some advice about how to reduce swelling and prevent complications. ![]() Oedema is the medical name for ‘swelling’. ![]()
