Patients with tracheobronchial disease frequently require mechanical ventilation during therapy and experience iatrogenic complications such as barotrauma and volutrauma. The purpose of this study was to determine whether perfluorocarbon-associated gas exchange (PAGE) results in lower ventilatory pressures and more efficient ventilation than that provided by conventional ventilation after tracheobronchial mucosal injury caused by smoke inhalation in neonatal piglets. Ten piglets were used for this prospective, randomized study. ⋯ Arterial blood gases showed significantly (P < .05) decreased pH, PO2, and elevated PcO2 levels in the control group past 12 hours after injury. The oxygenation index was significantly elevated (P < .05) in the control group past 12 hours after injury. PAGE shows potential for improving ventilation and survival immediately after severe smoke inhalation injury and may have clinical applications in other nonhomogeneous lung injuries.
