Goals and options in keeping preterm babies warm

Area of Science:

• Neonatalogy
• Pediatric Critical Care
• Thermoregulation Research

Background:

• The critical role of thermal environment control in preterm infant mortality was established over 50 years ago.
• Recent evidence underscores the ongoing importance of maintaining optimal thermal conditions for preterm neonates.
• Current practices face challenges in defining 'normal' temperature and assessing thermal balance accurately.

Purpose of the Study:

• To emphasize the significance of the thermal environment for preterm infants.
• To highlight the challenges in defining and monitoring 'normal' body temperature in preterm neonates.
• To discuss methods for ensuring thermal stability and preventing cold stress.

Main Methods:

• Continuous monitoring and display of both central and peripheral temperatures in preterm infants.
• Assessment of strategies to reduce evaporative heat loss at birth.
• Comparison of incubator versus radiant heater effectiveness.

Main Results:

• Continuous temperature monitoring provides early detection of cold stress, preceding changes in central temperature.
• Reducing evaporative heat loss at birth improves admission temperatures, but outcome effects are unproven.
• No conclusive data demonstrate the superiority of incubators over radiant heaters.

Conclusions:

• Continuous central and peripheral temperature monitoring is recommended for early cold stress detection in preterm infants.
• Further research is needed to validate the impact of interventions like reduced evaporative heat loss on infant outcomes.
• The comparative efficacy of incubators versus radiant heaters requires more robust evidence.
