Key Points

This research investigates how delayed sternal closure affects respiratory and hemodynamic parameters in pediatric cardiac surgery patients.
Conducted observational analysis of pediatric cardiac surgery patients
Measured changes in lung and chest wall compliance
Assessed hemodynamic parameters during and after sternal closure
Delayed sternal closure increased pleural pressure by approximately 2 cm H2O
Reduction in lung compliance without affecting chest wall compliance observed
Identified a need for optimized respiratory and circulatory support during recovery

Abstract

Delayed sternal closure increased Ppl by ∼2 cm H2O, which may reduce lung compliance without affecting chest wall compliance and contribute to hemodynamic stress. These changes may necessitate optimized respiratory and circulatory support during and after delayed sternal closure.
