Immediate skin-to-skin contact versus care under radiant warmer at birth in moderate to late preterm neonates - A randomized controlled trial

Objective: To compare the effect of immediate care at birth in skin-to-skin contact (SSC) or under a radiant warmer on cardiorespiratory stability at 60 minutes of age in moderate-to-late preterm neonates.

Methods: In this open-label, parallel-group, randomized controlled trial, neonates born at 33^0/7 to 36^6/7 weeks of gestation by vaginal delivery and breathing or crying were randomized to receive care at birth in SSC (n = 50) or under a radiant warmer (n = 50). In the SSC group, immediate care at birth including drying and clearing of the airway was provided in SSC over the mother's abdomen. SSC was maintained for an observational period of 60 minutes after birth. In the radiant warmer group, care at birth and post-birth observation was performed under an overhead radiant warmer. The primary outcome of the study was the stability of the cardio-respiratory system in late preterm infants (SCRIP) score at 60 minutes of age.

Results: Baseline variables were similar in the two study groups. The SCRIP score at 60 minutes of age was similar in the two study groups (median: 5.0, IQR: 5-6 vs. 5.0, 5-6). The mean axillary temperature at 60 minutes of age was significantly lower in the SSC group (°C; 36.4 ± 0.4 vs. 36.6 ± 0.4, P = 0.004).

Conclusion: It was feasible to provide immediate care at birth in moderate and late preterm neonates while being positioned in SSC with the mother. However, in comparison to care under a radiant warmer, this did not lead to better cardiorespiratory stability at 60 minutes of age.
