Summary
Cold injuries cause lasting microcirculation damage, affecting vascular tone and leading to tissue problems. This study evaluated patients with cold injuries and trophic disturbances, revealing significant changes in blood flow regulation.
Area of Science:
- Vascular Physiology
- Dermatology
- Regenerative Medicine
Background:
- Local cold injuries can lead to persistent microcirculatory dysfunction.
- Trophic disturbances in lower limbs are often associated with impaired vascular regulation.
- Understanding these changes is crucial for effective treatment and recovery.
Purpose of the Study:
- To comparatively evaluate the microcirculatory condition in patients with cold injuries.
- To assess the regulatory components of vascular tone in affected lower limbs.
- To identify the long-term effects of cold exposure on peripheral circulation.
Main Methods:
- Laser Doppler flowmetry was used for comparative evaluation.
- Microcirculation index and vascular tone components were measured.
- Analysis included patients with cold injuries and reconvalescents with trophic disturbances.
Main Results:
- A decreased microcirculation index was observed in all patients.
- Neurogenous and myogenous vascular tone showed an increase.
- Endothelial vascular tone exhibited a decrease in peak oscillation amplitude.
Conclusions:
- Cold exposure induces stable microcirculatory changes.
- These alterations in vascular tone contribute to dystrophic changes in tissues.
- Findings highlight the need for interventions addressing microcirculatory dysfunction post-cold injury.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.

01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
