During a 4-year period, 34 neonates were treated with high-frequency jet ventilation (HFJV) using two different HFJV systems. Twenty-three of the neonates had severe pulmonary air leaks, five had congenital left-sided diaphragmatic hernias, and six had end-stage respiratory failure without pulmonary air leaks. The two HFJV systems performed similarly in all pathologic conditions. Following HFJV, arterial blood gas values improved in 28 of the 34 patients (82%). Eleven patients (32%) ultimately survived. Of 23 patients with pulmonary air leaks, 17 (74%) improved, nine (39%) survived. One infant with diaphragmatic hernia and one with end-stage respiratory failure survived. Ten of 12 patients (85%) who died following eight or more hours of HFJV had significant tracheal histopathology in the region of the endotracheal tube tip. The lesions ranged from moderate erythema to severe necrotizing tracheobronchitis with total tracheal obstruction. HFJV can be useful in the treatment of severe pulmonary air leaks in neonates and may prove useful in the treatment of congenital diaphragmatic hernias. However, HFJV produces inflammatory injuries in the proximal trachea. More clinical and laboratory studies are needed to define the relative risks and benefits of this new therapy.

Extracorporeal membrane oxygenation (ECMO) has been successful in rescuing near term or term infants in cardio-respiratory failure that results from a reversible disease process. In most cases, only one course of ECMO is needed to save these infants. However, a second course of ECMO may be beneficial in a select group of infants when recurrent persistent pulmonary hypertension develops. Other than abstract form, this is the first report of the use of a second course of ECMO in the literature. The authors report on three infants, two with recurrent persistent pulmonary hypertension secondary to congenital diaphragmatic hernia and one with necrotizing tracheobronchitis after Group B streptococcal sepsis who were treated at their institution with a second course of ECMO. Technical considerations in using a second course of ECMO depend upon the initial vessel cannulation site, time elapsed between cannulations, and the condition of the original artery and vein. By adopting a stenting procedure in those infants whose initial trial off was equivocal, a second cannulation may be prevented in neonatal patients with recurrent persistent pulmonary hypertension.
