Neonatal Lung US

Presentation prepared by Dr Punnanee Wutthigate during her Neonatal Hemodynamics Clinical Research Fellowship at McGill University.
Lung US score
Scoring system from: "Brat, R., Yousef, N., Klifa, R., Reynaud, S., Aguilera, S. S., & De Luca, D. (2015). Lung ultrasonography score to evaluate oxygenation and surfactant need in neonates treated with continuous positive airway pressure. JAMA pediatrics, 169(8), e151797-e151797."

Score 0
Score 1
Score2
Score 3
Lung ultrasound demonstrating the lung-liver interface and diaphragm (liver on the right hand side of the image)
Another example of a Score 3 (consolidation)
Another example of a Score 3 (consolidation)
Pneumothorax
Lung ultrasound demonstrating a pneumothorax on the left side
Lung ultrasound demonstrating a pneumothorax on the left side
M-Mode applied on the LUS with pneumothorax on the left side demonstrating a barcode (stratosphere) sign
Lung ultrasound demonstrating severe B-lines (coalescent B-lines) without consolidation - Score 2.
M-Mode applied on the LUS on the contralateral (right) lung demonstrating absence of a pneumothorax. We can see the motion artefacts from the high frequency oscillation on the M-Mode. This image corresponds to the "sand on the beach" sign (absence of a pneumothorax)
Orientation of the linear probe on the chest of the newborn
Position of the linear probe or Butterfly-IQ+ probe for the lung ultrasound. Cursor of the probe towards the head of the baby (cranial orientation). RUL (Right upper lobe), LUL (left upper lobe), RLL (right lower lobe), LLL (left lower lobe), RLatL (right lateral lobe), LLatL (left lateral lobe).
Pleural Effusions
