About

This is a multicenter, unblinded, randomized controlled trial comparing drying vs. not drying before plastic wrapping for the thermoregulation of very preterm infants at birth. The aim of this study will be to compare two modes of thermal management (plastic wrapping with or without drying) for preventing heat loss at birth in very preterm infants.

Full description

Background: Hypothermia in preterm infants during the immediate postnatal phase is associated with morbidity and mortality and remains an unresolved, worldwide challenge.

A list of interventions, including adequate room temperature, use of infant warmers, polyethylene bags/wrap, pre-heated mattresses, caps and heated and humidified gases, to prevent thermal loss at birth in very preterm infants has been recommended, but a certain percentage of very preterm infants are hypothermic at the time of the neonatal intensive care unit (NICU) admission suggesting that further measures are needed. While drying is recommended for the thermal management of infants with gestational age >32 weeks, this procedure is not indicated for very preterm infants who should be put in a plastic wrap immediately at birth without drying. However, such indication is based on studies comparing wrapping without drying vs. drying without wrapping, while the potential advantages of combining these interventions were not explored. We hypothesized that drying before wrapping could prevent heat loss immediately after birth and reduce hypothermia at NICU admission in very preterm infants.

Objective: The aim of this study will be to compare two modes of thermal management (plastic wrapping with or without drying) for preventing heat loss at birth in very preterm infants.

Methods: This is a multicenter, unblinded, randomized controlled trial comparing drying vs. not drying before plastic wrapping for the thermoregulation of very preterm infants at birth. After obtaining parental consent, all infants with estimated birth weight <1500 g and/or gestational age ≤30+6 weeks will be assigned to be managed with or without drying before plastic wrapping. Room temperature and maternal temperature will be measured at the time of delivery. Patients allocated in both groups will be managed based on the current guidelines for neonatal resuscitation. The primary outcome measure will be the proportion of neonates in the normal thermal range (temperature 36.5-37.5°C) at NICU admission. Secondary outcome measures will be: proportion of neonates with hypothermia (<36.5°C and <36.0°C) at NICU admission; proportion of hyperthermic neonates (temperature >37.5°C) at NICU admission; temperature at 1 hour after NICU admission; proportion of intraventricular hemorrhage; proportion of respiratory distress syndrome; proportion of late onset sepsis; proportion of bronchopulmonary dysplasia; mortality before hospital discharge.
