Is this trial a fit for you?

Likely a good fit

Adults (18+) who had open-heart surgery, have a chest tube, can read Turkish, are clinically stable, and consent to participate.

Probably not a fit

Patients who are intubated, cognitively unable to follow instructions, or receiving analgesics beyond routine care may not benefit.

What this trial studies

This randomized, two-arm trial assigns 86 adults who have undergone open-heart surgery to either box breathing before chest tube removal plus routine care or routine care alone. The intervention uses a 4-4-4-4 breathing pattern for about five minutes with guidance immediately before chest tube removal. Outcomes include pain, anxiety, and dyspnea, as well as hemodynamic parameters, measured before and after the procedure. The study aims to determine if this simple, nonpharmacological technique can improve comfort during a common post-surgical step.

Why it matters

Potential benefit: If successful, box breathing could reduce pain and anxiety around chest tube removal and improve patient comfort.

How similar studies have gone: Nonpharmacological breathing techniques have shown promise for perioperative comfort in other settings, but this exact approach is being tested in chest tube removal after open-heart surgery.
