Air Leak Syndrome

Air leak syndrome has several manifestations and is common in neonates with meconium aspiration syndrome (MAS) due to air trapping. While pneumoperitoneum is classically a result of intestinal perforation, intra-abdominal free air may be a less common presentation of air leak syndrome. In the ventilated neonate, there is insufficient clinical evidence outlining management of pneumoperitoneum in this situation. We report a case of a term neonate with MAS and air leak syndrome who developed benign pneumoperitoneum (BPPT).

The Third

In reporting the third case of Wilson-Mikity syndrome in a full-term neonate, Drs. Keidel and Feingold1 appear instead to have described a classic case of meconium aspiration syndrome. Their patient, delivered with difficulty at 41 weeks' gestation, aspirated meconium at the time of delivery and was severely asphyxiated at birth. Respiratory distress developed after resuscitation and the baby was noted to have "diffuse granularity of both lung fields and hyperinflation indicating meconium aspiration." Later, when the chest film showed "hyperexpanded lungs with depressed diaphragms and cyst-like foci alternating with coarse infiltrates" their diagnostic impression apparently changed to Mikity-Wilson syndrome.

Air Leak Syndrome

Neonatal pneumopericardium (PPC) is a rare form of neonatal air leak syndrome with high morbidity and mortality. Air leak syndrome in the newborn is usually associated with active resuscitation, respiratory distress syndrome, meconium aspiration syndrome, mechanical ventilation, or trauma associated with labour. Neonatal PPC can be associated with other air leak syndromes such as pneumomediastinum, pneumothorax, pneumoperitoneum, and subcutaneous and interstitial emphysema. Spontaneous PPC is a rare event in the neonatal period. We report a case of PPC in association with pneumothorax in a nonventilated term infant. The infant responded to thoracocentesis without the need for pericardiocentesis.

Blood Flows

Neonatal resuscitation (NRP) guidelines suggest targeting 85–95% preductal SpO2 by 10 min after birth. Optimal oxygen saturation (SpO2) targets during resuscitation and in the post-resuscitation management of neonatal meconium aspiration syndrome (MAS) with persistent pulmonary hypertension (PPHN) remains uncertain. Our objective was to compare the time to reversal of ductal flow from fetal pattern (right-to-left), to left-to-right, and to evaluate pulmonary (QPA), carotid (QCA)and ductal (QDA) blood flows between standard (85–94%) and high (95–99%) SpO2 targets during and after resuscitation. Twelve lambs asphyxiated by endotracheal meconium instillation and cord occlusion to induce MAS and PPHN were resuscitated per NRP guidelines and were randomized to either standard (85–94%) or high (95–99%) SpO2 targets. Out of twelve lambs with MAS and PPHN, six each were randomized to standard and high SpO2 targets. Median [interquartile range] time to change in direction of blood flow across the ductus arteriosus from right-to-left, to left-to-right was significantly shorter with high SpO2 target (7.4 (4.4–10.8) min) compared to standard SpO2 target (31.5 (21–66.2) min, p = 0.03). QPA was significantly higher during the first 10 min after birth with higher SpO2 target. At 60 min after birth, the QPA, QCA and QDA were not different between the groups. To conclude, targeting SpO2 of 95–99% during and after resuscitation may hasten reversal of ductal flow in lambs with MAS and PPHN and transiently increase QPA but no differences were observed at 60 min. Clinical studies comparing low and high SpO2 targets assessing hemodynamics and neurodevelopmental outcomes are warranted.

Free Air

A pneumomediastinum is an air leak in which the free air is concentrated in the mediastinum. Although most neonatal pneumomediastinums do not require intervention, complications such as subsequent air leaks can arise. Proper radiologic identification, as well as an understanding of the anatomy and pathophysiology associated with a pneumomediastinum, are necessary for an accurate understanding and diagnosis. This article will review the interpretation of radiologic findings in a neonate with a pneumomediastinum.
