Effect of the Active Cycle of Breathing Technique on Coronary Artery Bypass Graft Patients' Outcomes

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.

  • Patients with preoperative lung collapse or pleural effusion.

Treatment and study plan

Active Cycle of Breathing Technique

Other
  • Patients will assume the sitting position and relax their shoulders, then perform the following:
  • Breathing control (abdominal breathing)
  • Chest expansion (thoracic breathing)
  • 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.

Primary outcomes

  1. Atelectasis

    Time frame: The first three postoperative days

    Atelectasis will be assessed using chest X-rays.

  2. Dyspnea

    Time frame: The first three postoperative days

    Dyspnea level will be assessed using the modified Borg scale.

  3. Functional capacity

    Time frame: The first three postoperative days

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

  4. Hemodynamic parameters

    Time frame: The first three postoperative days

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

  5. Chest expansion

    Time frame: The first three postoperative days

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

  6. Duration of chest tube

    Time frame: Up to 1 week

    Duration of chest tube

  7. Length of ICU stay

    Time frame: For up to 1 week

    Measure the duration of the patient's ICU stay

  8. Hemodynamic Parameters

    Time frame: For the first three postoperative days

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