Brief Summary

Following CABG surgery, patients are at risk for several complications. One of the most common complications is postoperative pulmonary complications, which include atelectasis and dyspnea. These complications cause prolonged ICU length of stay and increased health care costs. Several studies recommended the active cycle of breathing technique as a method that increases secretion removal and improves lung functions, thus reducing the incidence of postoperative pulmonary complications. Our study aims to investigate the effect of the active cycle of breathing technique on coronary artery bypass graft patients' outcomes.

Conditions

Coronary Artery Bypass; Coronary Arterial Disease (CAD)

Keywords

CABG; ACBT; Postoperative Pulmonary Complications; Chest tube duration; Hemodynamic parameters; Chest expansion

Outcome Measures

Primary Outcomes (8)

• Atelectasis

  Atelectasis will be assessed using chest X-rays.

  The first three postoperative days

• Dyspnea

  Dyspnea level will be assessed using the modified Borg scale.

  The first three postoperative days

• Functional capacity

  Functional capacity will be assessed using the six-minute walk test

  The first three postoperative days

• Hemodynamic parameters

  Hemodynamic parameters will include respiratory rate expressed as the number of cycles per minute, which will be assessed using the cardiac monitor

  The first three postoperative days

• Chest expansion

  Chest expansion will be measured at three points (axillary, xiphoid point, and umbilical level) using a measuring tape in centimeters.

  The first three postoperative days

• Duration of chest tube

  Duration of chest tube

  Up to 1 week

• Length of ICU stay

  Measure the duration of the patient's ICU stay

  For up to 1 week

• Hemodynamic Parameters

  Hemodynamic parameters will include oxygen saturation, which will be assessed using the pulse oximeter and will be expressed as a percentage %

  For the first three postoperative days

Study Arms (2)

Active Cycle of Breathing Technique

EXPERIMENTAL

Patients who will perform ACBT exercises in addition to the routine ICU care.

Other: Active Cycle of Breathing Technique

Control Group

NO INTERVENTION

Patients who will receive routine ICU care (chest physiotherapy and incentive spirometer) without ACBT.

Interventions

Active Cycle of Breathing Technique OTHER

* Patients will assume the sitting position and relax their shoulders, then perform the following: 1. Breathing control (abdominal breathing) 2. Chest expansion (thoracic breathing) 3. Huff cough (forced expiratory technique) * After completing the above actions, patients will be asked to cough up the residual deep sputum to promote pulmonary expansion. * The ACBT intervention will be performed for three days, each day two sessions, each session three courses, with 10 minutes of rest between them as needed.
