Decreased Body Temperature

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...

Methods of reducing fever

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:

Mechanism of heat transfer

Mechanism of heat transfer

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Temperature Measurement Sites

Temperature Measurement Sites

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...

Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Neonatal Medicine
Perinatal Care
Transport Medicine

Background:

Hypoxic-ischemic encephalopathy (HIE) is a serious condition in newborns.
Therapeutic hypothermia is a critical treatment for HIE.
Maintaining stable temperatures during neonatal transport is challenging but essential.

Purpose of the Study:

To evaluate the effectiveness of passive cooling during neonatal transport for infants with suspected HIE.
To assess the ability of a neonatal emergency transport service to maintain target temperatures (35°C ±0.5°C) during passive cooling.
To identify challenges and successes in temperature management during HIE neonatal transports.

Main Methods:

Retrospective analysis of rectal temperatures of 297 outborn newborns with suspected HIE during passive cooling transport.
Data collected from Neonatal Emergency Transport Service in Genoa and Rome, Italy.
Evaluation of temperature stability and achievement of the 35°C target range.

Main Results:

88.55% (263/297) of newborns maintained rectal temperatures within the target range of 35°C ±0.5°C.
5.05% (15/297) experienced temperatures above 35.5°C, and 6.39% (19/297) were below 34.5°C.
No infants experienced severe hypothermia (temperature <33°C).

Conclusions:

Passive cooling during neonatal transport is a satisfactory method for temperature management in HIE infants.
Experienced neonatal transport teams can achieve appropriate temperature control, minimizing risks of overcooling or significant temperature deviations.
Effective passive cooling during transport supports the initiation of therapeutic hypothermia upon arrival at the NICU.
