Heat and Cold Therapy e before application of heat or cold therapy, the client should understand its purpose, symptoms and precautions taken to prevent injury Assessment for Temperature Tolerance: e Before applying heat or cold therapies, the nurse must assess the client’s physical condition for signs of potential intolerance e First observe the area to be treated. Alterations in skin integrity increase the client’s risk for injury. Baseline skin assessment provide a guide for evaluating skin changes that might occur during therapy Contraindications to Heat and Cold Therapy e an area of bleeding should not be covered by a warm application because bleeding will continue e warm application are contraindication when the client has an acute, localized inflammation, cardiovascular problems (vasodilatation may disrupt blood supply to vital organs) e cold is contraindicated if the site of injury has edema because cold further retards circulation to the area and prevents the absorption of the interstitial fluid (edema) e if the client has impaired circulation (PVD, arteriosclerosis ), cold application further reduces blood supply e cold therapy is contraindicated in the presence of neuropathy because the client is unable to perceive temperature and damage resulting for temperature extremes e cold therapy is also contraindicated during shivering because it may intensify shivering and dangerously increase body temperature. e The nurse also assesses the client’s response to stimuli. Sensation to light touch, pinprick, and mild temperature variations reveals the ability of the client to recognize when heat or cold becomes excessive. e if the client has peripheral vascular disease, the nurse must pay attention to the integrity of the extremities (assess circulation by assessing capillary refill, observing skin color, and palpating skin temperatures, distal pulses, and edema) if signs of circulation inadequacy are present, question the order e level of consciousness influences the ability of the person to perceive heat, cold, and pain. If a client is confused or unresponsive, the nurse must make frequent observations of skin integrity during therapy e the nurse must also assess the condition of the equipment being used (no leaks, cracks, or damage) and the evenness of the temperature distribution Body Responses to heat and cold e exposure to heat and cold can cause systemic and local responses e systemic responses occur through heat-loss mechanisms , such as sweating and vasodilatation, or mechanisms promoting heat conservation , such as vasoconstriction and poiloereection, and heat production (shivering)

local responses occur through stimulation of temperature sensitive nerve ending within the skin, which sends impulses from the periphery to the hypothalamus, which triggers adaptive responses for maintenance of normal body temperature e the body can tolerate wide variations in temperature. Normal temperature of skin
