NCT05192785

Brief Summary

Background: Incentive spirometry is used in addition to care, especially in reducing pulmonary complications after surgery. Complications in the cardiovascular and pulmonary systems can basically be determined by blood values and vital signs, which are important objective data of haemodynamics. Aim: This study was designed to test the hypothesis that the use of incentive spirometry in conjunction with postoperative pulmonary rehabilitation care has a notable impact on arterial blood gas, oxygen saturation (SpO2), and vital signs. Methods: This randomised, controlled trial was designed using a repeated-measures design. The study was planned to be conducted at the cardiovascular surgery clinic of a university hospital. It was intended that data from patients undergoing coronary artery bypass graft surgery would be analyzed. All patients were planned to receive routine pulmonary rehabilitation, with incentive spirometry added for the experimental group. Outcome measures were designed to include arterial blood gas values, oxygen saturation, and vital signs recorded during the postoperative period.

Outcome Measures

Primary Outcomes (4)

  • Partial Pressure of Oxygen (PaO2)

    Measurement of the partial pressure of oxygen (mmHg) obtained via arterial blood gas analysis to evaluate oxygenation levels.

  • Partial Pressure of Carbon Dioxide (PaCO2)

    Measurement of the partial pressure of carbon dioxide (mmHg) obtained via arterial blood gas analysis to evaluate ventilation efficiency.

    Preoperative, postoperative day 1, postoperative day 2, and postoperative day 3.

  • Arterial Oxygen Saturation (SaO2)

    Measurement of the arterial oxygen saturation percentage (%) obtained via arterial blood gas analysis.

    Preoperative, postoperative day 1, postoperative day 2, and postoperative day 3.

  • Peripheral Oxygen Saturation (SpO2)

    Measurement of the peripheral oxygen saturation percentage (%) using a non-invasive pulse oximetry device.

    Preoperative, postoperative day 1, postoperative day 2, and postoperative day 3.

  • Change in Pulse Rate

    Preoperative, postoperative day 1, postoperative day 2, postoperative day 3.

Study Arms (2)

Control group

NO INTERVENTION

Participants in the control group received routine postoperative pulmonary rehabilitation care without incentive spirometry. Routine care included deep breathing exercises, coughing exercises, pain assessment and management, and early mobilization during hospitalization. Arterial blood gas parameters, peripheral oxygen saturation, and vital signs were measured and recorded during the resting period at the end of postoperative days 1, 2, and 3.

Incentive Spirometry Group

EXPERIMENTAL

Participants in the experimental group received routine postoperative pulmonary rehabilitation care plus incentive spirometry. Routine care included deep breathing exercises, coughing exercises, pain assessment and management, and early mobilization during hospitalization. Incentive spirometry was explained, demonstrated, and applied preoperatively and continued after extubation when the patient was fully awake. The intervention included 10 to 20 breaths every 1 to 2 hours according to patient tolerance. Arterial blood gas parameters, peripheral oxygen saturation, and vital signs were measured and recorded during the resting period at the end of postoperative days 1, 2, and 3.

Device: Incentive Spirometry Group

Interventions

A flow-oriented incentive spirometer with three compartments and target volumes of 600, 900, and 1200 mL was used. Patients were instructed in its use preoperatively and continued the application after extubation when fully awake. The intervention was performed every 1 to 2 hours while awake, for a total of 10 to 20 breaths according to tolerance. Patients performed deep breathing exercises first, followed by incentive spirometry, and then coughing exercises. During the application, the bed was elevated to 45 degrees and the patient was positioned in long sitting. Patients were instructed to inhale slowly and deeply to raise the balls to the target level, hold their breath for 3 to 5 seconds, and then exhale normally. The exercise was repeated according to tolerance, and coughing exercises were performed after every five repetitions.
