Should incentive spirometry be incorporated into postoperative care for patients undergoing chest wall resection?

Incentive Spirometry in Post-Operative Management of Chest Wall Resection

Incentive spirometry should be incorporated into postoperative care for chest wall resection patients, as lung expansion interventions reduce pulmonary complications, though incentive spirometry offers no proven advantage over simple deep breathing exercises and early ambulation.

Evidence-Based Recommendation

The American College of Physicians guideline explicitly states that for surgical patients at risk for pulmonary complications, any type of lung expansion intervention is superior to no prophylaxis 1. However, the guideline emphasizes that no single modality demonstrates clear superiority over others, and incentive spirometry is noted primarily for being "the least labor-intensive" option 1.

Key Supporting Evidence

For thoracic surgery specifically, the most recent high-quality randomized controlled trial (2018) involving 387 patients undergoing lung resection found no difference in postoperative pulmonary complications between patients receiving incentive spirometry plus physiotherapy versus physiotherapy alone (12.3% vs 13.0%, p=0.88) 2. This study showed no differences in:

• Pneumonia rates
• Mechanical ventilation requirements
• Hospital length of stay
• Readmission rates

A 2024 propensity-matched study of 304 lung resection patients similarly found no significant improvement in pulmonary complications, oxygen requirements, atelectasis, or hospital stay with incentive spirometry added to early ambulation 3.

Clinical Algorithm for Implementation

Standard Approach for All Chest Wall Resection Patients:

1. Implement mandatory lung expansion therapy (any modality is acceptable)
2. Early ambulation (cornerstone intervention)
3. Deep breathing exercises with coughing
4. Consider incentive spirometry as the practical choice due to minimal staff time requirements

For High-Risk Subgroups:

Patients with ≥2 risk factors (age ≥75, COPD, current/recent smoking, BMI ≥30) may derive greater benefit from incentive spirometry 4, 5. In these populations:

• A 2013 trial showed larger observed differences favoring incentive spirometry (14% vs 23% complication rates in high-risk patients) 4
• Prioritize incentive spirometry specifically for COPD patients and smokers where emerging evidence suggests potential benefit 5

Critical Caveats

Patient adherence is the major limitation of incentive spirometry effectiveness 5. The device only works if patients use it as prescribed, which remains challenging to achieve consistently in clinical practice.

The guideline evidence base comes primarily from abdominal surgery patients, not chest wall resections specifically 1. However, chest wall resection carries similar or higher pulmonary complication risk, making lung expansion interventions even more critical.

Avoid the misconception that incentive spirometry is essential or superior—it is simply one acceptable option among several equivalent lung expansion techniques 1, 2.

Practical Implementation

Use incentive spirometry in chest wall resection patients because:

• It fulfills the guideline requirement for lung expansion therapy 1
• It requires minimal nursing time compared to chest physiotherapy 1
• It provides visual feedback that may enhance patient motivation 5
• It serves as backup when patients cannot perform deep breathing exercises independently 1

Combine with:

• Aggressive early mobilization (non-negotiable)
• Adequate pain control (epidural analgesia reduces pulmonary complications more effectively than systemic opioids) 1
• Avoidance of long-acting neuromuscular blockers like pancuronium 1
