Hypothermia

Hypothermia is a condition characterized by a significant decrease in body temperature, which occurs when the core body temperature drops below 35°C (95°F). This condition can lead to serious organ and system failure, including cardiac arrest and death, if not treated promptly. Hypothermia can result from prolonged exposure to cold temperatures, hypothermia in water, or physical activity in cold conditions. Symptoms of the condition develop gradually and include shivering, disorientation, weakness, decreased consciousness, and, in extreme cases, loss of consciousness.

History of the disease and interesting historical facts

Hypothermia has been known to mankind for centuries. During World War II, soldiers fighting on the northern fronts were the first to develop accurate methods for diagnosing and treating hypothermia. The study of this condition became especially relevant during research expeditions to the Arctic and Antarctic, where scientists exposed themselves to significant risks. In the 1950s, a number of resuscitation methods based on the principles of warming the body were developed, which saved the lives of thousands of people. An important step in understanding hypothermia was the study of thermoregulation mechanisms, which made it possible to develop highly effective methods for preventing and treating this condition.

Epidemiology

According to the WHO, hypothermia is one of the leading causes of death in countries with cold climates. In the population, groups vulnerable to developing hypothermia include the elderly, homeless people, alcoholics, and people forced to work outdoors in the cold season. Statistics show that thousands of people are exposed to this condition every year. Approximately 1,000 cases of hypothermia are recorded in the winter alone in the northern regions of the United States and Canada. The incidence of the condition is double for men compared to women, which may be due to their greater physical activity in cold conditions and less careful behavior.

Genetic predisposition to this disease

To date, there are no proven genetic markers that would directly indicate a predisposition to hypothermia. However, there are several genes that can indirectly affect the body's thermoregulation. For example, genes responsible for the synthesis of proteins involved in heat exchange processes may be important. Scientists are also studying the effect of polymorphisms in genes associated with metabolism, immune response, and stress response on the level of resistance to low temperatures. Research is ongoing, and perhaps in the near future we will be able to gain a more complete understanding of the genetic predisposition to hypothermia.

Risk factors for the development of this disease

The main risk factors contributing to the development of hypothermia can be conditionally divided into physical and chemical.

• Physical factors:
• Extreme low temperatures;
• Long stay outdoors;
• Contact with cold water;
• Physical fatigue and dehydration.
• Chemical factors:
• Alcohol consumption, which weakens thermoregulation;
• Use of certain medications that affect metabolism.

In addition, factors such as poor nutrition, chronic diseases, and age can influence the occurrence of hypothermia. In old age, the body's thermoregulation deteriorates, which increases the risk of hypothermia.

Diagnosis of this disease

The main symptoms of hypothermia are:

• Shiver;
• Weakness and fatigue;
• Slowness of thinking;
• Loss of coordination;
• Loss of consciousness in severe cases.

Laboratory tests may include electrolyte levels, glucose, and renal function. Radiologic examinations are generally not used, but otolaryngologic examination data should be comparable between body temperatures. All diagnostic measures are aimed at determining the degree of hypothermia and its causes, such as freezing, hypothermia, or systemic diseases.

Differential diagnosis includes distinction between hypothermia and other conditions, low-volume shock, exhaustion, and intoxication, which may require the use of additional diagnostic methods.

Treatment

Treatment of hypothermia begins with warming the patient, which can be done in several ways. General therapy includes investigating and eliminating the causes of hypothermia.

Pharmacological treatment involves the use of antidotes for alcohol intoxication and the use of drugs that increase metabolism.

Surgical treatment may be necessary if complications such as frostbite or asphyxia develop.

Other treatments include thermoregulation, blankets, active rewarming, and inhalation techniques.

List of drugs used to treat this disease

• Glucose;
• Epinephrine;
• Isotonic sodium chloride solution;
• B vitamins;
• Medicines for suppressing nervous reflexes.

Disease monitoring

Monitoring the patient's condition in hypothermia includes monitoring body temperature, assessing cardiac activity, and level of consciousness. It is important to monitor the dynamics and adhere to the prescribed course of treatment. The prognosis is usually favorable with timely medical attention. However, advanced cases can lead to dangerous complications such as cardiogenic shock, asphyxia, or hypotension.

Age-related features of the disease

Hypothermia can have different manifestations depending on the age group. In children, it can develop more quickly due to lower body weight and ineffective thermoregulation. Older people also have a reduced ability to thermoregulate, which leads to higher risks. In younger people, signs of hypothermia can be masked by vigorous physical activity, making diagnosis difficult.

Advice from Dr. Oleg Korzhikov

According to the observations of Dr. Oleg Korzhikov, the most important preventive measure for hypothermia is taking care of your own condition during the cold season:

• Dress in layers to stay warm.
• Avoid drinking alcohol before going out into the cold.
• Check your body temperature regularly when spending long periods of time outdoors.
• Remember to maintain good hydration levels.

The doctor draws attention to the need to consult a doctor at the first signs of hypothermia, as timely intervention can save lives.
