Summary

This study looks at two simple breathing exercises—coughing exercises and incentive spirometry (using a plastic device)—to see which helps children aged 6 to 18 recover better after heart surgery. About 99 children will be randomly assigned to one of three groups: coughing exercises, incentive spirometry, or standard care. They will do the exercises every 3 hours for the first 3 days after surgery, and researchers will track their breathing, oxygen levels, and overall recovery to find the most effective method.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
coughing exercises and incentive spirometry
What this could lead to
If this trial succeeds, it could show that simple coughing exercises are as good as or better than a device for helping children breathe easier and recover faster after heart surgery.
What could go wrong
This is a small, early-stage study with only 99 children, so results may not apply to all kids. The exercises are low-risk, but some children may find them uncomfortable or hard to do.

Inclusion Crit * Children aged 6 to 18 years scheduled for elective cardiac surgery. * Postoperative extubation within 24 hours and judged clinically stable to begin respiratory therapy. * Hemodynamically stable. Exclusion Criteria: * Pre-existing moderate-to-severe chronic lung disease requiring baseline oxygen therapy. * Neuromuscular disorders significantly impairing cough/inspiratory effort. * Emergency surgery, ongoing major bleeding. * Prolonged mechanical ventilation \>72 hours or tracheostomy on admission.
