Clinical records of 27 newborns treated with high frequency ventilation in a hospital neonatal service in Madrid were retrospectively studied. High frequency ventilation is a technique with specific indications that has recently been applied in some neonatal pathologies as an alternative to conventional ventilation. The respirators, model 2 Volumetric Diffusive Respirators, were used in 24 of the 27 cases because of failure of conventional ventilation. The 27 newborns weighed an average of 1850 +or- 944 g and ranged from 900 to 4000 g. Their average gestational age was 32 +or- 4 weeks, and the range was 26-42 weeks. 19 had respiratory difficulties stemming from hyaline membrane disease, 3 had congenital diaphragmatic hernias, 2 had pulmonary hypertension, and one each had meconium aspiration syndrome, septic shock from group B streptococcus, and diaphragmatic agenesia. 66% were delivered by cesarean. The pH, paCO2, and paO2 improved significantly between 2 and 6 hours after initiation of HFV treatment. Values in the normal range were reached at 6.5 +or- 14 hours for pH, 30 +or- 50 hours for paCO2, and 6.5 +or- 10 hours for paO2. No hemodynamic modifications were attributed to HFV. The most significant complications were ectopic air (62%) and necrotizing tracheobronchitis (25%). Broncopulmonary dysphasia was diagnosed in 20%, ductus in 33%, and intracraneal hemorrhage in 25%. The case fatality rate was 70%. Ten newborns improved definitively with HFV and proceeded to conventional ventilation. Two later succumbed to other causes. The study showed that HFV can lead to serious complications and should be applied with great prudence despite it great potential benefit.

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.

In this Series paper, we review the current evidence for the use of high-flow oxygen therapy, inhaled gases, and aerosols in the care of critically ill patients. The available evidence supports the use of high-flow nasal cannulae for selected patients with acute hypoxaemic respiratory failure. Heliox might prevent intubation or improve gas flow in mechanically ventilated patients with severe asthma. Additionally, it might improve the delivery of aerosolised bronchodilators in obstructive lung disease in general. Inhaled nitric oxide might improve outcomes in a subset of patients with postoperative pulmonary hypertension who had cardiac surgery; however, it has not been shown to provide long-term benefit in patients with acute respiratory distress syndrome (ARDS). Inhaled prostacyclins, similar to inhaled nitric oxide, are not recommended for routine use in patients with ARDS, but can be used to improve oxygenation in patients who are not adequately stabilised with traditional therapies. Aerosolised bronchodilators are useful in mechanically ventilated patients with asthma and chronic obstructive pulmonary disease, but are not recommended for those with ARDS. Use of aerosolised antibiotics for ventilator-associated pneumonia and ventilator-associated tracheobronchitis shows promise, but the delivered dose can be highly variable if proper attention is not paid to the delivery method.
