Duration of skin-to-skin care and rectal temperatures in late preterm and term infants

BACKGROUND: Hypothermia during the newborn period is widely regarded as a major contributory cause of significant morbidity and mortality of newborn infants. Thermoprotective behaviours such as skin-to-skin care (SSC) or the use of appropriate devices have been recommended as simple tools for the avoidance of neonatal hypothermia. We examined the relation between the duration of skin-to-skin care and infant temperature change after birth in suboptimal delivery room temperatures. METHODS: We reviewed the medical charts of all vaginally born infants of gestational age ≥ 35 weeks born January-July 2018 and admitted to the well-baby nursery. After SSC was discontinued, the infant’s rectal temperature was measured to determine the frequency and severity of hypothermia. RESULTS: The charts of 688 vaginally born infants were examined. Our mean delivery room temperature was 21.7 (SD 2.2) °C, well below the WHO recommendation of 25 °C. After SSC 347 (50.4%) infants were normothermic (temperature 36.5–37.5 °C), 262 (38.0%) were mildly hypothermic (36.0-36.4 °C), and 79 (11.4%) were moderately hypothermic (32.0-35.9 °C). The mean skin-to-skin time in infants was 63.9 (SD 20.9) minutes. SSC duration was associated with increase in rectal temperature for patients of gestational ages ≥ 38 weeks and with decrease in rectal temperature in patients of gestational age < 38 weeks. CONCLUSION: SSC is effective, even at suboptimal delivery room temperatures, for promoting normothermia in infants of ≥ 38 weeks’ gestation but may not provide adequate warmth for infants of < 38 weeks.
