About this trial
This randomized controlled trial aims to evaluate the effects of box breathing performed before chest tube removal on pain, anxiety, dyspnea, and hemodynamic parameters in patients undergoing open-heart surgery. A total of 86 patients will be randomly assigned in a 1:1 ratio to either the box breathing group or the control group. Participants in the intervention group will perform the 4-4-4-4 box breathing technique for approximately five minutes before chest tube removal in addition to routine care, while participants in the control group will receive routine care only. Pain, anxiety, dyspnea, and hemodynamic parameters will be assessed before and at specified time points after chest tube removal.

Treatments tested in this trial
Box breathing
BehavioralParticipants will perform the 4-4-4-4 box breathing technique approximately five minutes before chest tube removal. The technique consists of inhaling through the nose for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and holding after exhalation for 4 seconds. Participants will perform 15 consecutive cycles for approximately five minutes under the verbal guidance of the researcher. The intervention will be completed immediately before chest tube removal. Routine medical treatment and nursing care will continue throughout the intervention.

Trial outcomes
Primary outcomes
1
Pain Intensity
Pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst possible pain). Higher scores indicate greater pain intensity.
Time frame
Before the intervention, immediately after chest tube removal, and 5, 15, and 30 minutes after chest tube removal.Secondary outcomes
1
Anxiety Level
Anxiety will be assessed using the 10-cm Visual Analog Scale for Anxiety (VAS-A), ranging from 0 (no anxiety) to 10 (highest possible anxiety). Higher scores indicate greater anxiety.
Time frame
Before the intervention, immediately after chest tube removal, and 5, 15, and 30 minutes after chest tube removal.2
Dyspnea Level
Dyspnea will be assessed using the 10-cm Visual Analog Scale for Dyspnea (VAS-D), ranging from 0 (no dyspnea) to 10 (worst imaginable dyspnea). Higher scores indicate greater dyspnea.
Time frame
Before the intervention, immediately after chest tube removal, and 5, 15, and 30 minutes after chest tube removal.3
Systolic Blood Pressure
Systolic blood pressure will be measured using a bedside patient monitor and recorded in millimeters of mercury (mmHg).
Time frame
Before the intervention, immediately after chest tube removal, and 5, 15, and 30 minutes after chest tube removal.4
Diastolic Blood Pressure
Diastolic blood pressure will be measured using a bedside patient monitor and recorded in millimeters of mercury (mmHg).
Time frame
Before the intervention, immediately after chest tube removal, and 5, 15, and 30 minutes after chest tube removal.Sponsors and contacts
