Respiratory Failure Without Hypercapnia

Postoperative respiratory failure (PORF) remains a critical driver of morbidity, mortality, and incremental care costs in surgical populations. Traditional escalation often involves invasive mechanical ventilation, which is associated with ventilator-associated pneumonia (VAP), prolonged intensive care unit (ICU) stays, and increased resource burden.

This study aims to evaluate the clinical association between intraoperative paravertebral block and the reduction of postoperative complications following thoracic surgery.
