Study Notes
Heat and Cold Therapies
- Learning Outcomes: Identify heat and cold therapy modes, describe physiologic effects of local applications, identify indications and contraindications, and recognize safety precautions.
Terminology
- Antipyretic: Reduces fever
- Evaporation: Heat loss through vaporization
- Pallor: Paleness
- Compress: A pad soaked in a liquid for application
- Conduction: Heat transfer via direct contact
- Fever: Elevated body temperature
- Radiation: Heat or light waves radiated away
- Shivering: involuntary muscle contractions to generate heat
- Convection: Heat transfer through moving fluids
- Hyperemia: Increased blood flow
- Hyperthermia: Elevated body temperature
- Suppuration: Formation of pus
- Cryotherapy: Cold therapy
- Thermotherapy: Heat therapy
- Cyanosis: Bluish discoloration of skin
- Insulator: Material that minimizes heat transfer
- Vasoconstriction: Narrowing of blood vessels
- Hypothermia: Low body temperature
- Erythema: Redness of skin
- Mottling: Spotted discoloration of skin
- Vasodilation: Widening of blood vessels
Temperature Regulation
- Temperature is regulated by a feedback system, balanced between heat production and loss.
- The body's thermostat is the hypothalamus, maintaining 36-37.5°C.
Heat Transfer Processes
- Conduction, convection, radiation, and evaporation.
Heat and Cold Applications
- Local and systemic effects
- Thermotherapy: Heat application
- Cryotherapy: Cold application
Physiologic Effects of Heat
- Beneficial for subacute and chronic inflammation, not acute.
- Promotes analgesia and sedation by releasing endorphins.
- Blocks pain transmission via gate control theory.
Local Effects of Heat
- Vasodilation, increasing blood flow to area, bringing oxygen, nutrients, antibodies, and leukocytes.
- Promotes soft tissue healing, and increases suppuration (formation of pus)
- Increases capillary permeability, possibly leading to edema.
- Useful for musculoskeletal conditions; joint stiffness, arthritis, contractures, low back pain.
Local Effects of Cold
- Vasoconstriction, reducing blood flow to the area, reducing oxygen supply, and waste removal.
- Reduces inflammation and swelling.
- Prolonged exposure can cause impaired circulation, tissue damage, pallor, coolness, numbness, and possible blisters.
- Often used for sports injuries like sprains, strains, fractures, to minimize post-injury swelling and bleeding.
Systemic Effects of Heat and Cold
- Heat applied to large areas can cause excessive peripheral vasodilation, potentially lowering blood pressure.
Thermal Tolerance
- Precautions for use of heat and cold applications are necessary (neurosensory impairment, impaired mental status, impaired circulation, immediately after injury/surgery, open wounds - open wound treatment requires specialized care.)
Variables Affecting Physiological Tolerance
- Body part sensitivity, size of exposed area, the individual's tolerance, length of exposure, and skin integrity.
Temperature for Application
- Different descriptor terms for temperature (Very cold, Cold, Cool, Tepid, Warm, Hot, Very Hot)
Applying Heat and Cold
- Different types of heat (dry, moist, using various forms like hot water bottles, moist compresses, etc.).
- Guidelines for local application: tolerance assessment, identifying contraindications, explanation of application to the patient, assessing skin, monitoring for discomfort, proper disposal of equipment, observation for reactions, recording patient's response.
Contraindications for Heat
- First 24 hours after trauma (increased bleeding, swelling).
- Active hemorrhage.
- Non-inflammatory edema (heat increases swelling).
- Skin disorders.
Contraindications for Cold
- Open wounds, impaired circulation, allergies, hypersensitivity.
Assessment
- Body Temperature.
