Coughing exercises versus incentive spirometry for breathing recovery after pediatric heart surgery

Effect of Coughing Exercises Versus Incentive Spirometry on Respiratory Outcomes and Postoperative Recovery Among Children Undergoing Cardiac Surgery.

Not applicable Interventional University of Baghdad · NCT07405333

What this trial studies

This randomized interventional study assigns eligible children after elective cardiac surgery to one of three groups: coughing exercises, incentive spirometry, or standard postoperative care. Children in the two intervention groups perform the assigned breathing exercises every three hours for the first three postoperative days while all patients receive daily monitoring of vitals, oxygen saturation, and lung function. Primary outcomes include a standardized postoperative respiratory score, and secondary outcomes include recovery quality measures, incidence of pulmonary complications, and length of pediatric ICU stay. The trial focuses on children extubated within 24 hours who are hemodynamically stable and follows them through early postoperative recovery milestones.

Who should consider this trial

Good fit: Children aged 6 to 18 years scheduled for elective cardiac surgery who are extubated within 24 hours and judged clinically and hemodynamically stable are ideal candidates.

Not a fit: Children with moderate-to-severe chronic lung disease requiring baseline oxygen, neuromuscular disorders impairing cough or inspiration, those needing prolonged ventilation (>72 hours), tracheostomy, or emergency surgery are unlikely to benefit from these interventions.

Why it matters

Potential benefit: If successful, the study could identify a simple, low-cost breathing method that reduces lung complications and speeds recovery after pediatric cardiac surgery.

How similar studies have performed: Breathing exercises and incentive spirometry have been tested in adults and some pediatric settings with mixed results, and rigorous data specifically in post–pediatric cardiac surgery patients remain limited.
