Objective To investigate if the use of a visible respiratory function monitor (RFM) to use lower tidal volumes (Vts) during positive pressure ventilation (PPV) in the delivery room (DR) reduces the need of surfactant administration and invasive mechanical ventilation during the first 72 hours after birth of preterm infants <32 weeks' gestational age (GA). Study Design Infants <32 weeks' GA (n = 106) requiring noninvasive PPV were monitored with a RFM at birth and randomized to visible (n = 54) or masked (n = 52) display on RFM. Pulmonary data were recorded during the first 10 minutes after birth. Secondary analysis stratified patients by GA (<28, 28–29+6, or ≥30 weeks). Results Median expiratory Vts during inflations were greater in the masked group (7 mL/kg) than in the visible group (5.8 mL/kg; p = 0.001) same as peak inflation pressure (PIP) administered (21.5 vs. 19.7 cmH2O; p < 0.001). Consequently, minute volumes were greater in the masked group (256 vs. 214 mL/kg/min; p < 0.001), with no differences in respiratory rate. These differences were higher in those <30 weeks' GA. There was no difference in the need of surfactant administration or intubation during the first 72 hours of age. Conclusion Using a RFM in the DR prevents the use of large Vt and PIP during respiratory support inflations, mostly in the more immature newborn infants, but with no other short-term benefits. The Gregorio Marañón University Hospital Research and Ethics Committees provided Ethics approval.

The fetal-to-neonatal transition poses an extraordinary challenge for extremely low birth weight (ELBW) infants, and postnatal stabilization in the delivery room (DR) remains challenging. The initiation of air respiration and the establishment of a functional residual capacity are essential and often require ventilatory support and oxygen supplementation. In recent years, there has been a tendency towards the soft-landing strategy and, subsequently, non-invasive positive pressure ventilation has been generally recommended by international guidelines as the first option for stabilizing ELBW in the delivery room. On the other hand, supplementation with oxygen is another cornerstone of the postnatal stabilization of ELBW infants. To date, the conundrum concerning the optimal initial inspired fraction of oxygen, target saturations in the first golden minutes, and oxygen titration to achieve desired stability saturation and heart rate values has not yet been solved. Moreover, the retardation of cord clamping together with the initiation of ventilation with the patent cord (physiologic-based cord clamping) have added additional complexity to this puzzle. In the present review, we critically address these relevant topics related to fetal-to-neonatal transitional respiratory physiology, ventilatory stabilization, and oxygenation of ELBW infants in the delivery room based on current evidence and the most recent guidelines for newborn stabilization.

Pre-term delivery is one of the leading causes of foetal and perinatal mortality. However, perinatal risk factors associated with intra-partum foetal death in preterm deliveries have not been well studied. To analyse foetal mortality and perinatal risk factors associated with intra-partum foetal mortality in pregnancies of less than 32 weeks gestational age. The study included all preterm deliveries between 22 and 31 +1 weeks gestational age (WGA), born in a tertiary-referral hospital, over a period of 7 years (2008-2014). A logistic regression model was used to identify perinatal risk factors associated with intra-partum foetal mortality (foetal malformations and chromosomal abnormalities were excluded). During the study period, the overall foetal mortality was 63.1% (106/168) (≥22 weeks of gestation) occurred in pregnancies of less than 32 WGA. A total of 882 deliveries between 22 and 31+6 weeks of gestation were included for analysis. The rate of foetal mortality was 11.3% (100/882). The rate of intra-partum foetal death was 2.6% (23/882), with 78.2% (18/23) of these cases occurring in hospitalised pregnancies. It was found that Assisted Reproductive Techniques, abnormal foetal ultrasound, no administration of antenatal steroids, lower gestational age, and small for gestational age, were independent risk factors associated with intra-partum foetal mortality. This study showed that there is a significant percentage intra-partum foetal mortality in infants between 22 and 31+6 WGA. The analysis of intrapartum mortality and risk factors associated with this mortality is of clinical and epidemiological interest to optimise perinatal care and improve survival of preterm infants.

The recommendations of the International Liaison Committee on Resuscitation (ILCOR) published at the end of 2025 provide the current scientific framework for neonatal resuscitation and support in the transition to extrauterine life. As in previous updates, the Neonatal Resuscitation Group of the Spanish Society of Neonatology (GRN-SENeo) presents a review and position document analyzing the changes introduced with respect to the previous guideline and adapting the current evidence to the specific circumstances and health care context of Spain. The aim of this document is to disseminate the position of the group on the implementation of these recommendations at the national level, reached by consensus and addressing the most controversial aspects through the nominal group technique. The management algorithms are reviewed and updated, incorporating new aspects in pre-delivery neonatal management planning and briefing, umbilical cord management, initial stabilization, ventilation and oxygen supplementation strategies, as well as the use of new devices and vascular access routes. Through this guideline, the GRN-SENeo establishes a sustained institutional reference framework aimed at ensuring homogeneity, safety and quality in the management of the newborn in the delivery room, while fulfilling its commitment to continuous updating as scientific knowledge evolves.
