Abstract
Objective: To describe the characteristics of early hypothermia in extremely preterm neonates at the National Hospital of Obstetrics and Gynecology. Methods: A cross-sectional descriptive study was conducted on 333 extremely preterm neonates at the National Hospital of Obstetrics and Gynecology from August 1, 2023, to September 30, 2024. Body temperature data were collected directly. Results: The prevalence of early hypothermia in very preterm neonates was 34.2%, with the majority being mild hypothermia (36.0 - 36.4°C) accounting for 33.3%, moderate hypothermia (32.0 - 35.9°C) accounting for 0.9%, and no cases of severe hypothermia (< 32.0°C) recorded. Early hypothermia was most common among infants born at 28 weeks of gestation (61.3%) and least common in those born at 31 weeks (13.9%). Small-for-gestational-age (SGA) infants had a higher prevalenceof early hypothermia (64.3%) compared to appropriate-for-gestational-age (AGA) infants (31.5%). Regarding timing, early hypothermia occurred predominantly immediately after birth (64.9%), followed by after umbilical venous catheter insertion and surfactant administration (35.1%). The duration of early hypothermia was ≥ 15 minutes in 62.3% of cases and < 15 minutes in 37.7%. Conclusion: Early hypothermia is relatively common in very preterm neonates, particularly in those born at 28 weeks of gestation and those who are small for gestational age. This condition typically occurs immediately after birth and often lasts for ≥ 15 minutes.
