Decreased Body Temperature01:29

Decreased 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...
Factors Affecting Body Temperature01:28

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may  include:
Methods of reducing fever01:22

Methods 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.
Pharmacological Methods of Reducing Fever:
Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...
Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Summary

Accidental hypothermia is common in trauma patients and worsens outcomes. Early and effective rewarming is crucial for survival, but aggressive rewarming may increase mortality in some cases.

Area of Science:

  • Trauma Care
  • Emergency Medicine
  • Physiology

Context:

  • Hypothermia (body core temperature < 35 °C) affects up to 66% of trauma patients on emergency room admission.
  • Temperatures below 34 °C increase post-traumatic complications and decrease survival.
  • A core temperature below 32 °C is associated with 100% mortality in polytraumatized patients.

Purpose:

  • To highlight the critical impact of accidental hypothermia in multiple trauma patients.
  • To emphasize the necessity of effective rewarming strategies.
  • To discuss the pathophysiological effects and rewarming considerations.

Summary:

  • Hypothermia significantly impacts hemodynamic, coagulatory, and immune systems, leading to increased blood loss and susceptibility to infections.
  • Mild hypothermia causes vasoconstriction and increased cardiac output, while severe hypothermia (< 32 °C) can lead to cardiac arrest.
  • Effective rewarming is essential, but aggressive rewarming (> 0.5 °C/h) is linked to increased mortality and should be reserved for patients with hemorrhagic shock.

Impact:

  • Early and effective rewarming is vital for improving outcomes in hypothermic trauma patients.
  • Further research is needed to clarify potential protective effects of therapeutic hypothermia post-resuscitation.
  • Understanding hypothermia's effects is key to optimizing trauma patient management and survival rates.
