Insights

Maintaining normal infant temperature after birth is crucial for preterm infants. This review examines delivery room thermal care, including delayed cord clamping, to improve infant outcomes and reduce mortality risks.

Area of Science:

  • Neonatalogy
  • Perinatal Medicine
  • Pediatric Critical Care

Background:

  • Abnormal infant temperature in preterm neonates is linked to higher morbidity and mortality.
  • Preterm infants face risks of abnormal temperature in the delivery room (DR).
  • While hypothermia is common, hyperthermia is also a concern due to prevention efforts.

Purpose of the Study:

  • To review current evidence and recommendations for thermal care in the DR for preterm infants.
  • To explore the impact of emerging DR practices, like delayed cord clamping (DCC), on infant temperature.
  • To identify future research directions in neonatal thermoregulation.

Main Methods:

  • Literature review of current evidence and guidelines on neonatal thermal care.
  • Analysis of the relationship between interventions like DCC and infant temperature regulation.
  • Synthesis of findings to inform best practices in the DR.

Main Results:

  • Abnormal temperature is prevalent in very preterm infants, posing an independent mortality risk.
  • Existing guidelines recommend interventions to prevent heat loss, yet abnormal temperatures persist.
  • Emerging practices like DCC may influence infant thermal stability.

Conclusions:

  • Optimal thermal care in the DR remains a challenge for preterm infants.
  • Further research is needed to understand the effects of new DR interventions on thermoregulation.
  • Evidence-based guidelines are essential to minimize abnormal infant temperatures and improve survival rates.

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...

Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Thermoregulation01:26

Thermoregulation

The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Body Temperature01:25

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Temperature Measurement Sites01:14

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...
