Pathophysiology of neonatal transition and meaningful measures for the initial stabilisation of extremely premature...

This report discusses the physiological aspects of neonatal transition from breathing liquid to air. Further, we discuss reasonable medical interventions to actively assist a gentle transition, and focus on team aspects of preparing both the perinatal team and parents for the challenging situation of preterm labour and delivery. Our aim is to critically evaluate current concepts on the physiology of neonatal transition and the current assessment of the newborn infant, to present means to facilitate non-traumatic pulmonary aeration and ways to foster successful teamwork and professional parental guidance in the delivery room. The authors report on their own work and on that of other research groups, as recently published in peer reviewed medical journals. When born, the newborn needs to rapidly clear his/her lungs from fluid to establish breathing. Active fluid transport and passive resorption help to establish the pulmonary functional residual capacity (FRC). Prenatal administration of corticosteroids helps to form and maintain the FRC of the newborn. Many very low gestational age neonates (ELGAN) will breathe at birth but require medical assistance. This is best done by giving distending positive airway pressure at levels of 5 cmH(2)O, or greater. Monitoring of these infants should be by peripheral pulse oximetry. Some ELGANs may require non-invasive ventilation and/or exogenous Surfactant replacement, and even fewer may require intubation and mechanical ventilation. The obstetric and neonatal teams need to coordinate their joined efforts to secure a safe delivery for mother and child. Ways of communication between teams and parents are presented. Many neonatal teams use video recording as a tool to assess and improve their work. We give insights into the use of video as a means to improve teamwork and patient care alike.
