Prone position to treat bronchopleural fistula in post-operative acute lung injury

Prone position is used to treat patients with acute lung injury or acute respiratory distress syndrome because it improves gas exchange and respiratory mechanics. When broncho-pleural fistula occurring, the clinical impact of prone position is limited; however, its use could be tried when the fistula is small or other potential treatments are not possible.

A 45-year-old man with oesophageal cancer submitted to a total oesophagectomy with intrathoracic transposition of the stomach developed post-operatively respiratory failure and pneumothorax, which were worsened by unilateral pleural rupture and severe subcutaneous emphysema produced after an attempt to introduce through anterior chest wall a second drainage tube.

Prone position associated with lung protective strategy was implemented during 16-18 h daily and after the change of position PaO2/FiO2 increased of 35% and PaCO2-PetCO2 decreased about 40%; at 4th day under treatment, the subcutaneous emphysema and pneumothorax could not be detected either clinically or radiologically. On the 6th day the lung lesion could not be observed under the CT-scan.

In a patient that underwent a major thoracic surgery the addition of prone positioning to protective lung ventilation rendered possible not only the healing of the acute lung injury, but also the quick repair of a lung rupture owing to a thoracic drainage attempt.
