Hypothermia in trauma patients: predicting the big chill
Critical Care (London, England)
|November 9, 2012
Summary
Hypothermia is a significant risk factor for trauma patient mortality, often overlooked by physicians. This study identifies key environmental and prehospital factors contributing to hypothermia in trauma patients upon admission.
Area of Science:
- Emergency Medicine
- Trauma Care
- Environmental Health
Background:
- Hypothermia is a critical, yet often overlooked, factor in trauma patient mortality.
- The prevalence of hypothermia in trauma is high, frequently misattributed as secondary to the injury.
- While hypothermia's impact on mortality is known, risk factors remain under-identified.
Purpose of the Study:
- To identify major risk factors associated with hypothermia in trauma patients.
- To incorporate environmental and prehospital factors into hypothermia prediction models.
- To improve the understanding of hypothermia's multifactorial causes in trauma settings.
Main Methods:
- Retrospective analysis of trauma patient data.
- Inclusion of environmental variables (e.g., ambient temperature).
- Assessment of prehospital care interventions and duration.
Main Results:
- Environmental factors and prehospital care significantly influence hypothermia risk.
- Traditional variables alone are insufficient for predicting hypothermia.
- Specific prehospital interventions correlate with reduced hypothermia incidence.
Conclusions:
- Environmental conditions and prehospital management are crucial determinants of hypothermia in trauma.
- A comprehensive approach, including environmental and prehospital factors, is necessary for accurate hypothermia prediction.
- Addressing these factors can mitigate hypothermia-related mortality in trauma patients.

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...

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.

01:25Increased 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.
01:19Homeostatic 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...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
