About this trial

This randomized controlled pilot study will compare intermittent positive pressure breathing (IPPB) with incentive spirometry (IS) in adult patients undergoing thoracic surgery. The study aims to evaluate the effects of these two postoperative pulmonary rehabilitation interventions on lung volume recovery, respiratory muscle strength, oxygenation, pulmonary complications, and overall postoperative recovery. Participants will be randomly assigned to either the IPPB group or the IS group. Assessments will be performed before surgery and after the intervention period.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Willing and able to provide written informed consent. Adults aged 18 years or older. Undergoing thoracic surgery. Considered eligible by a specialist physician to participate in pulmonary rehabilitation training.

Disqualifiers

Unable to cooperate with the study procedures. Untreated pneumothorax. Severe hemodynamic instability. Active hemoptysis or gastrointestinal bleeding. Intracranial pressure greater than 15 mmHg. Recent facial, oropharyngeal, or cranial surgery or injury. Tracheoesophageal fistula. Recent esophageal surgery. Nausea or vomiting. Pulmonary bullae identified on imaging.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Intermittent Positive Pressure Breathing

    Other intervention

    Intermittent positive pressure breathing will be provided as a postoperative lung expansion intervention from postoperative day 0 through postoperative day 3.

  • Incentive Spirometry

    Other intervention

    Participants will perform incentive spirometry from postoperative day 0 through postoperative day 3 under therapist supervision 3 to 4 times per day. Each supervised session will consist of 3 sets of 10 slow, deep inspirations, with a 2- to 3-second inspiratory hold. Participants will also be encouraged to practice independently while awake.

Treatment groups

Trial outcomes

Primary outcomes

1

Change in Lung Volume

Change in lung volume, including tidal volume and minute ventilation, measured using a respiratory volume measurement device.

Time frame
Baseline (preoperative) and postoperative day 3
2

Change in Maximal Inspiratory Pressure

Change in maximal inspiratory pressure (MIP) measured using a respiratory pressure measurement device to assess inspiratory muscle strength.

Time frame
Baseline (preoperative) and postoperative day 3
3

Change in Maximal Expiratory Pressure

Change in maximal expiratory pressure (MEP) measured using a respiratory pressure measurement device to assess expiratory muscle strength.

Time frame
Baseline (preoperative) and postoperative day 3

Secondary outcomes

1

Change in C-Reactive Protein

Change in serum C-reactive protein (CRP) concentration as an indicator of postoperative inflammatory response.

Time frame
Baseline (preoperative) and postoperative day 3
