TRACHEAL WORK OF BREATHING IN NEONATES WITH TRACHEOESOPHAGEAL FISTULA BEFORE AND AFTER SURGICAL REPAIR VIA COMPUTATIONAL FLUID DYNAMICS ASSESSMENT

Topic overview

Key takeaways

• TEF with EA creates quantifiable increases in neonatal respiratory effort that can be measured via computational fluid dynamics modeling.
• Tracheal resistive work of breathing (TR-WOB) provides objective metrics to assess respiratory mechanics pre- and post-TEF repair.
• Post-surgical tracheomalacia may continue to impact respiratory effort even after anatomic TEF correction.
• Computational modeling enables comparison of patient-specific TR-WOB values against normal neonatal baselines.
• Quantifying TR-WOB may guide timing of intervention and predict which neonates need prolonged respiratory support post-repair.
