Decreased Body Temperature01:29

Decreased Body Temperature

1.0K
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...

Temperature Measurement Sites

3.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Assessing Body Temperature - Temporal Artery

1.1K
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

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...

Methods of reducing fever01:22

Methods of reducing fever

1.2K
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.

Summary
This summary is machine-generated.

Hypothermia in young infants often indicates significant underlying pathology beyond infections. Older age, ill appearance, temperature instability, and abnormal white blood cell counts are key indicators for further evaluation.

Area of Science:

  • Pediatrics
  • Neonatology
  • Emergency Medicine

Background:

  • Hypothermia in young infants (≤90 days) is commonly linked to immature thermoregulation.
  • However, it can also signal serious, underlying medical conditions requiring prompt diagnosis and management.

Purpose of the Study:

  • To determine the prevalence and types of significant pathology in young infants presenting with hypothermia.
  • To explore associations between hypothermia and presenting characteristics or evaluation findings.

Main Methods:

  • A multicenter, retrospective cohort study was conducted over 5 years.
  • Included were infants ≤90 days with documented hypothermia (≤36.0 °C) in the emergency department or upon admission.
  • Significant pathology was defined as a diagnosis warranting hospitalization; multivariate logistic regression analyzed associations.

Main Results:

  • Of 998 infants, 32% had significant pathology, including 4% with serious infections (bacterial, HSV) and 28% with other significant diagnoses.
  • Older age (29-90 days), ill appearance, repeated temperature instability, and abnormal white blood cell counts were significantly associated with pathology.

Conclusions:

  • Hypothermia in young infants frequently presents with significant, non-infectious pathologies.
  • Clinical decision tools for managing hypothermic infants should consider a broader range of potential diagnoses beyond serious infections.
