Moist cold: cold compress
What are the factors that may cause unfavorable reac ons?
The age of pa ent, loca on of the applica on(some areas are more sensi ve)
Impaired circula on, impaired sensa on(diabe c pa ents)
Individual tolerance to change temperature
What does local heat applica on cause?
produces dila on, or an increase in diameter, of the blood vessels in the area as the body tries
to rid itself of excess heat
increased blood supply to the area, and ssue metabolism increases
Why would heat applica on be used?

prevent heat loss
leads to decreased blood supply to the area.
Why would cold applica ons be used?

Allow the cast to dry before pu3ng any pressure or weight on the cast.
Elevate the cast above heart level for the first 24 to 48 hours to decrease swelling and pain.
Gently move the toes or fingers frequently to prevent swelling and joint s ffness and to increase
circula on.
Apply ice to the casted extremity to reduce swelling.
Take precau ons to prevent dirt, sand, powder, and other foreign par cles from becoming
trapped under the cast.
Do not apply powder for itching under the cast. Do not use any object to scratch the skin under
the cast.
Do not engage in ac vi es that could cause injury because of impairment of your physical
abili es
