Pathophysiological Impact of Delayed Sternal Closure on the Respiratory System and Hemodynamics in Pediatric Cardiac Surgery Patients

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
