In a premature neonate with a left-sided congenital diaphragmatic hernia, during ventilation, sudden desaturation occurs. What is the most appropriate step?

• A. Pull endotracheal tube from the right mainstem
• B. Ventilate with positive end-expiratory pressure (PEEP) and administer furosemide
• C. Pass an oral gastric tube to decompress the stomach
• D. Place a chest tube on the right side

Answer: (D)

When a premature neonate with a left-sided congenital diaphragmatic hernia suddenly desaturates during ventilation, think of a pneumothorax causing rapid loss of oxygenation. The most urgent action is to relieve the trapped air in the pleural space. In this scenario, placing a chest tube on the right side is the best option because the left side already contains herniated abdominal viscera. Introducing a chest tube on the left could risk injuring stomach or bowel that have herniated into the left chest. Draining the right pleural space safely decompresses a potential pneumothorax and can rapidly improve ventilation and oxygenation without risking injury to the herniated organs. Other steps, like adjusting intubation to avoid mainstem intubation, adding PEEP, or decompressing the stomach with an orogastric tube, do not address the immediate life-threatening issue of a pneumothorax as effectively as promptly establishing a chest tube to relieve pleural air.
