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...
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.

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:
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...
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Summary

Hypothermia in trauma patients worsens outcomes by contributing to the lethal triad. Active warming and therapeutic hypothermia show promise in improving patient survival from severe hemorrhage.

Area of Science:

  • Trauma care
  • Emergency medicine
  • Physiology

Background:

  • Traumatic hemorrhage can lead to hypovolaemic shock, overwhelming the body's compensatory mechanisms.
  • Hypovolaemia contributes to the lethal triad: hypothermia, acidosis, and coagulopathy, creating a detrimental cycle.
  • Spontaneous hypothermia significantly worsens outcomes for trauma patients.

Purpose of the Study:

  • To examine the role of hypothermia in trauma.
  • To assess the impact of prehospital temperature control on trauma patient outcomes.
  • To review literature on active warming and therapeutic hypothermia in trauma care.

Main Methods:

  • Literature review focusing on hypothermia in trauma.
  • Analysis of studies on prehospital temperature management.
Keywords:

  • Evaluation of active warming and clinically induced hypothermia interventions.

    • Main Results:

    • Spontaneous hypothermia has severe negative consequences for trauma victims.
    • Both active warming and clinically induced hypothermia can yield positive patient outcomes.
    • Clinically induced hypothermia's benefits, including an extended golden hour, may outweigh risks like coagulopathy.

    Conclusions:

    • Active warming is a viable method to improve outcomes by preventing spontaneous hypothermia and interrupting the lethal triad.
    • Clinically induced therapeutic hypothermia represents a promising future direction for improving survival rates in catastrophic hemorrhage.
    • Temperature management is crucial for mitigating the lethal triad and improving trauma patient prognosis.
