Cryotherapy Flashcards
Decreased blood flow, decreased metabolic rate, less accumulation of metabolites and chemical irritants. More effective when cold and compression combined.
Edema Reduction
Elevate pain threshold, counterirritants may lessen pain sensation by simulation thermal receptors, and decrease in chemical irritant response edema reduced.
Pain Reduction
Reflexively affected by decrease in pain. Muscle tightness may be decrease if cold is sufficient to decrease pain.
Muscle Spasm Reduction
Cold Uticaria
Cold allergy can cause hives, allergic reaction.
Cryoglobinemia
Kidney disorder linked to cold exposure.
Paroxysmal cold hemoglobinuria
Cold exposure leads to blood in the urine.
Precaution : Applying cold over superficial branch of a main nerve.
Lateral Knee and Posterolateral Elbow.
Precaution : Hypertension Present
Monitor BP (Blood Pressure).
Precaution : Poor Sensation
Need to watch for abnormal color.
Precaution : Young or elderly.
Have poor temperature regulation and limited ability to communicate.
Adverse Effect of Nerve Damage?
Don’t exceed 15 minutes. Irreversible nerve blocks will occur if the nerve is brought to 23-32 degrees F. Nerve irritation - tingling.
Adverse Effect of Frostbite?
Don’t use compression to attach cold pack.
Adverse Effect of Rebound Phenomena?
Do not exceed 30 Minutes
