Long-term high-frequency jet ventilation in neonates.
High-frequency jet ventilation (HFJV) markedly improved the ventilatory status of 2 neonates with severe respiratory failure refractory to conventional mechanical ventilatory support. However, after approximately 1 wk of HFJV, both patients expired from causes not directly related to ventilatory compromise. Autopsy showed no gross alterations in tracheal or bronchial mucosa but did reveal microscopic lesions which could be attributable to HFJV.
