Comparative evaluation of axillary and rectal temperatures across different gestational ages in newborns admitted to the neonatal intensive care unit: a cross-sectional study.

Objective: Maintaining normothermia is crucial for neonatal survival, especially in preterm infants prone to temperature instability. This study evaluates the correlation and variability between axillary and rectal temperatures at Neonatal Intensive Care (NICU) admission across gestational age ranges of 23-28, 29-32, 33-36, and ≥ 37 weeks, aiming to inform improved neonatal thermal management strategies.

Methods: This cross-sectional study was conducted at King Abdulaziz Medical City, Riyadh, from October 2023 to April 2024, involving 160 infants.

Rectal and axillary admission temperature in preterm infants less than 32 weeks' gestation, a prospective study.

Objectives: The purpose of this research was to evaluate the differences between rectal and axillary temperature measurements in preterm infants who were born less than 32 weeks' gestation using digital thermometers upon their admission to the Neonatal Intensive Care Unit (NICU).

Methods: Prospective, observational, single centre study. Rectal and axillary temperatures measurements were performed using a digital thermometer.
