Mediastinal Shift Index: A Novel Postnatal Measurement of Mediastinal Movement that Predicts Survival in Neonates With Congenital Diaphragmatic Hernia on Extracorporeal Membrane Oxygenation

In brief

This study introduces the Mediastinal Shift Index, a quantitative radiographic tool to measure mediastinal displacement in CDH neonates requiring ECMO support. The novel measurement correlates mediastinal positioning on chest X-rays with survival outcomes, offering clinicians an objective prognostic marker for risk stratification in this critically ill population.

• Mediastinal shift in CDH neonates reflects mass effect from herniated abdominal contents displacing thoracic structures contralaterally.
• A novel Mediastinal Shift Index can be measured on standard chest radiographs in CDH patients requiring ECMO support.
• The degree of mediastinal shift correlates with survival outcomes in CDH neonates on ECMO, serving as a prognostic indicator.
• Quantifying mediastinal position postnatally provides objective assessment of CDH severity beyond prenatal imaging findings.
• Radiographic measurement of mediastinal shift offers a simple bedside tool to stratify risk in critically ill CDH neonates.
