Cold compression

Cold compression is a combination of

cryotherapy Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy may be used to treat a variety of tissue lesions. The most prominent use of the term refers to the surgical treatment, ...

and static compression, commonly used for the treatment of pain and inflammation after acute injury or surgical procedures. Cryotherapy, the use of ice or cold in a therapeutic setting, has become one of the most common treatments in orthopedic medicine. The primary reason for using cryotherapy in acute injury management is to lower the temperature of the injured tissue, which reduces the tissue's metabolic rate and helps the tissue to survive the period following the injury. It is well documented that metabolic rate decreases by application of cryotherapy. A study done found that current literature on the use of cryotherapy on acute

has insufficient evidence for the efficacy. Static compression is often used in conjunction with cryotherapy for the care of acute injuries. To date, the primary reason for using compression is to increase external pressure on the tissue to prevent edema formation (swelling). This occurs by hindering fluid loss from the vessels in the injured area, making it more difficult for fluids to accumulate. Ice with compression is significantly colder than ice alone due to improved skin contact and increased tissue density caused by extended static compression. Tissue reaches its lowest temperature faster and the tissue maintains its cool even after treatment ends. Compression therapy has been used in deep venous thrombosis prevention, wound care, as well as managing edema. Literature suggests that compression therapy use for

ankle fractures will be beneficial for edema reduction and therefore, will probably be beneficial for pain and ankle joint mobility as well. Post operative arthroscopic surgeries also shows significant recovery with cold compression. It has been studied following facial surgery where it has been found to decrease pain and swelling on day two or three. In athletes, cryotherapy has its greatest effect on recovery by using it within the first 24 hours of exercise or injury. Cryotherapy has also been shown that it can increase joint flexibility. It is unclear if it affects the risk of bruising.

Devices

Continuous cold therapy devices (also called ice machines) which circulate ice water through a pad are currently the subject of class action lawsuits for skin and tissue damage caused by excessive cooling or icing time and lack of temperature control. Reported injuries range from

Wraps

Cold compression wraps using either re-freezable ice or gel are a much safer product, as such products do not exceed the cooling or icing time recommended by the established medical community. Many of the ice wraps available use adjustable elastic straps to aid in compression over the injured areas. More advanced single-use wraps have guidelines to indicate how the bandage should be applied in order to achieve optimum compression required for an acute injury. Most ice wraps that use ice, have a built-in protective layer, so ice is not applied directly to the skin, which can result in a burn to the area, sometimes known as a " cryoburn".
