Study Notes
Heat-Related Illnesses in Older Adults
- Less subcutaneous tissue: Older adults have reduced fatty tissue under their skin, making cooling more difficult.
- Decreased thirst mechanism: They may not feel thirsty even when dehydrated, leading to fluid imbalances.
- Impaired urine concentration: Difficulties in urine concentration contribute to dehydration in older adults.
- Inadequate fluid intake: Fear of incontinence leads many older adults to not drink sufficient fluids.
- Fear of crime: Hesitation to open windows or use fans due to safety concerns can exacerbate heat issues.
Heat Stroke
- Causes of heat stroke: Includes thermal injury at the cellular level, coagulopathies, and damage to vital organs from extreme heat or excessive exercise.
- Key symptoms: Profound CNS dysfunction (confusion, delirium, coma), elevated body temperature (40.6°C or higher), hot dry skin, absence of sweating, tachycardia, and hypotension.
- Distinguishing from heat exhaustion: Heat stroke presents with high body temperatures, no sweating, and can lead to coma or seizures.
Heat Exhaustion
- Symptoms: Includes headaches, anxiety, syncope, and profuse diaphoresis.
- Management: Patients should lie supine in a cool environment with IV or oral fluids when tolerated. Oral sodium and electrolyte supplements may be given.
Pain Management
- Analgesics: Administer prescribed pain relief; avoid massaging the affected areas.
- Elevation: Protect and elevate the injured parts to mitigate swelling.
Frostbite
- Condition description: Caused by exposed body parts to freezing temperatures; severity depends on exposure duration and environmental conditions.
- Injury assessment: Initial assessment may not reveal the full extent of injury from cold exposure.
Hypothermia
- Definition: Hypothermia occurs when core body temperature drops below 35°C (95°F).
- Causes: Often results from cold exposure, inability to maintain body temperature, or concurrent medical conditions.
- Risk factors: High-risk groups include older adults, infants, and individuals with concurrent illnesses or substance abuse.
Management of Frostbite
- Initial steps: Remove constrictive clothing and allow the patient to rest. Controlled rewarming is crucial.
- Rewarming technique: Use a circulating bath at 37°C to 40°C for 30-40 minutes; repeat until circulation is restored.
Monitoring in Heat-Related Conditions
- Continuous monitoring: Vital signs, urine output, and blood chemistry should be frequently evaluated.
- Temperature monitoring: Core body temperature must be assessed using a thermistor in esophagus, bladder, or rectum.
- Wet clothing: Increases the heat loss, worsening hypothermic conditions.
