The aim of this study was to establish the reference values of preductal oxygen saturation (SpO2) in healthy infants immediately after birth. SpO2 recordings of 200 term neonates (vaginal group;n=150 and cesarean group;n=50) with regular respiratory pattern were evaluated. The median SpO2 values in the first, fifth and tenth minutes were 71, 92, and 98% in vaginal deliveries and 70, 79, and 96% in cesarean deliveries, respectively. ⋯ The time needed to reach a SpO2>90% was three times longer in cesarean deliveries. Healthy neonates are poorly saturated immediately after birth. The duration to reach a SpO2>90% was longer in infants born by cesarean deliveries.

Case Reports
Heterozygous ABCA3 mutation associated with non-fatal evolution of respiratory distress.
A boy without symptoms up to 12 months of age started with persisting cough followed by respiratory failure at 18 months of age, resulting in mechanical ventilation because of alveolar proteinosis. Lung biopsy showed PAS-positive material. PCR was negative for CMV, Pneumocystis jiroveci and adenovirus. ⋯ Analysis of the ATP-binding cassette transporter A3 (ABCA3; OMIM 601615) gene showed a compound heterozygous mutation from paternal W1148X and maternal T1114A. Alveolar lavage with 720 mg of bovine surfactant allowed weaning from ventilator support. Heterozygous mutation in the ABCA3 gene could be associated with a milder evolution as compared to the homozygous frequently lethal evolution.

Airway clearance techniques are an important part of the respiratory management in children with cystic fibrosis, bronchiectasis and neuromuscular disease. They are also, however, frequently prescribed in previously healthy children with an acute respiratory problem with the aim to speed up recovery. The current review explores the evidence behind this use of airway clearance techniques in children without underlying disease. ⋯ It is necessary to name the specific airway clearance technique used in treatment rather than to just state "chest physiotherapy," a term that is often confused with chest clapping or vibration plus postural drainage. There is little evidence that airway clearance techniques play a role in the management of children with an acute respiratory problem. Physicians routinely prescribing airway clearance techniques in previously healthy children should question their practice.
