About

Pain associated with rib movement cause inability to cough and breathe deeply that leads to reduction in the tidal volume and predisposes to significant atelectasis, sputum retention, pneumonia and a reduction in functional residual capacity .These factors in turn lead to decreased lung compliance, ventilation perfusion mismatch, hypoxemia and respiratory distress. Therefore, effective pain relief remains the cornerstone of management to prevent serious respiratory complications .

Full description

Thoracic paravertebral block and other regional techniques like intrapleural block and intercostal nerve blocks have variable success and high potential for local anaesthetic toxicity. Serratus anterior plane block is relatively novel technique that is less invasive, easier to perform and improve pulmonary function that reduces the incidence of pneumonia, number of ventilator days, and mortality, especially those sustaining five or more rib fractures
