The scientific basis for postoperative respiratory care

Area of Science:

• Pulmonary Medicine
• Respiratory Therapy
• Critical Care

Background:

• Postoperative pulmonary complications (PPCs) significantly increase healthcare costs, morbidity, and mortality.
• Current respiratory therapy practices for PPC prevention often lack robust scientific evidence.

Purpose of the Study:

• To critically evaluate the evidence base for common respiratory therapy techniques used in preventing PPCs.
• To highlight the need for evidence-based practices and further research in respiratory care for surgical patients.

Main Methods:

• Review of existing scientific literature on respiratory therapy interventions for PPCs.
• Analysis of the evidence supporting techniques such as incentive spirometry, CPAP, and chest physical therapy.

Main Results:

• Limited evidence supports the efficacy of incentive spirometry alone in preventing PPCs.
• Continuous positive airway pressure (CPAP) shows potential benefit in high-risk hypoxemic patients.
• Chest physical therapy may exacerbate atelectasis due to pain and splinting.

Conclusions:

• Many widely used respiratory therapy techniques for PPCs lack strong evidence.
• A focus on evidence-based practices and further multicenter trials for PPC bundles is crucial.
• Intraoperative ventilation strategies require greater attention for their role in PPC development.
