Successful lung donation at the age of 6 weeks: Challenges and lessons learned.

A clinical case of successful procurement and transplantation of bilateral lungs from 6-week-old infant with sepsis secondary to bacterial meningitis is reported. Forty-one-day-old male infant (height 60 cm, weight 4 kg) died of cerebral edema secondary to Escherichia coli meningitis and bacteremia. Preretrieval assessment included the following: arterial gases; pO 50.4 kPa (378 mm Hg), pCO 4.9 kPa (37 mm Hg), on FiO 100%, PEEP 5 cm H O. Fiberoptic bronchoscopy showed no secretions nor mucosal inflammation; CXR revealed clear lung fields and pleural spaces. Inspection revealed dense adhesions in pericardial cavity and purulent left hemithorax effusion (urgent Gram-stain came back as negative) but there was no consolidation in the lung. Good compliance of the lungs on inflation/deflation test was observed. The lungs were retrieved using the technique described. The recipient was a 4-month-old infant with alveolar capillary dysplasia and malaligned pulmonary veins. Implantation of the lungs was performed via bilateral thoracosternotomy on cardiopulmonary bypass, cooling to 30°C. Elective support with nitric oxide was used postoperatively. Two years after the transplantation, the recipient doing well with normal lung function. Lung procurement from a 6-week donor with infectious complications and prolonged ventilation is a challenging undertaking but can be successful and should be attempted whenever possible given the paucity of organs available for pediatric recipients.
