Show moreBackgroundInfants with a congenital diaphragmatic hernia (CDH) and expected mild pulmonary hypoplasia have an estimated survival rate of 90%. Current guidelines for delivery room management do not consider the individual patient's disease severity, but an individualized approach with spontaneous breathing instead of routine mechanical ventilation could be beneficial for the mildest cases. We developed a resuscitation algorithm for this individualized approach serving two purposes: improving the success rate by structuring the approach and providing a guideline for other centers. MethodsAn initial algorithm was discussed with all local stakeholders. Afterwards, the resulting algorithm was refined using input from international experts. ResultsEligible CDH infants: left-sided defect, observed to expected lung-to-head ratio >= 50%, gestational age at birth >= 37.0 weeks, and no major associated structural or genetic abnormalities. To facilitate fetal-to-neonatal transition, we propose to start stabilization with non-invasive respiratory support and to adjust this individually. ConclusionsInfants with mild CDH might benefit from an individualized approach for neonatal resuscitation. Herein, we present an algorithm that could serve as guidance for centers implementing this.

Show moreBackground: Preterm infants are commonly supported with 5-8 cmH(2)O CPAP. However, animal studies demonstrate that high initial CPAP levels (12-15 cmH(2)O) which are then reduced (termed physiological based (PB)-CPAP), improve lung aeration without adversely affecting cardiovascular function. We investigated the feasibility of PB-CPAP and the effect in preterm infants at birth.Methods: Preterm infants (24-30 weeks gestation) were randomized to PB-CPAP or 5-8 cmH(2)O CPAP for the first 10 min after birth. PB-CPAP consisted of 15 cmH(2)O CPAP that was decreased when infants were stabilized (heart rate >= 100 bpm, SpO(2) >= 85%, FiO(2) <= 0.4, spontaneous breathing) to 8 cmH(2)O with steps of ~2/3 cmH(2)O/min. Primary outcomes were feasibility and SpO(2) in the first 5 min after birth. Secondary outcomes included physiological and breathing parameters and short-term neonatal outcomes. Planned enrollment was 42 infants.Results: The trial was stopped after enrolling 31 infants due to a low inclusion rate and recent changes in the local resuscitation guideline that conflict with the study protocol. Measurements were available for analysis in 28 infants (PB-CPAP n = 8, 5-8 cmH(2)O n = 20). Protocol deviations in the PB-CPAP group included one infant receiving 3 inflations with 15 cmH(2)O PEEP and two infants in which CPAP levels were decreased faster than described in the study protocol. In the 5-8 cmH(2)O CPAP group, three infants received 4, 10, and 12 cmH(2)O CPAP. During evaluations, caregivers indicated that the current PB-CPAP protocol was difficult to execute. The SpO(2) in the first 5 min after birth was not different [61 (49-70) vs. 64 (47-74), p = 0.973]. However, infants receiving PB-CPAP achieved higher heart rates [121 (111-130) vs. 97 (82-119) bpm, p = 0.016] and duration of mask ventilation was shorter [0:42 (0:34-2:22) vs. 2:58 (1:36-6:03) min, p = 0.020]. Infants in the PB-CPAP group required 6:36 (5:49-11:03) min to stabilize, compared to 9:57 (6:58-15:06) min in the 5-8 cmH2O CPAP group (p = 0.256). There were no differences in short-term outcomes.Conclusion: Stabilization of preterm infants with PB-CPAP is feasible but tailoring CPAP appeared challenging. PB-CPAP did not lead to higher SpO(2) but increased heart rate and shortened the duration of mask ventilation, which may reflect faster lung aeration. Show less
