We report the case of a 35 years old female patient suffering from Staphylococcus aureus induced abortion in the 7th/8th week of gestation. Sepsis with acute respiratory failure (ARDS) developed, which could be treated successfully. Pneumonia, caused by Pseudomonas aeruginosa, induced a recurrence of ARDS, complicated by a persistent incomplete atelectasis of the left lung. Independent ventilation of both lungs with increased pressure on the left side combined with bronchoscopy guided instillation of 1 g of bovine surfactant (Alveofact), caused improvement of arterial oxygenation and radiological signs, signalling airation of collapsed lung areas.

Clinical TrialHigh-frequency oscillatory ventilation for infants and children with adult respiratory distress syndrome.
Two infants and two children suffered from severe hypoxemia, presenting as a ratio of arterial to alveolar PaO2 < 0.1, persisting for more than 3 hours in spite of high settings on conventional mechanical ventilator. Adult respiratory distress syndrome was diagnosed with the support of bilateral diffuse haziness on chest radiographs. High-frequency oscillatory ventilation with high-lung-volume strategy resulted in prompt decrease in oxygenation index and increase in ratio of arterial to alveolar P O2 in three (75%) of the 4 patients within 6 hours. ⋯ There were 2 episodes of pneumothorax developing during high-frequency oscillatory ventilation. After decreasing mean airway pressure and amplitude, the airleak resolved with chest tube insertion. We conclude that high-frequency oscillatory ventilation with high-lung-volume strategy may be an effective rescue therapy to relieve profound hypoxemia in infants and children with adult respiratory distress syndrome.

Coagulopathic-induced membrane dysfunction during extracorporeal membrane oxygenation: a case report.
This paper describes an unusual complication of membrane dysfunction during extracorporeal membrane oxygenation (ECMO) for treatment of neonatal respiratory distress. A 2.8-kg term infant presented to our facility in severe respiratory distress and was diagnosed with primary pulmonary hypertension. After routine priming of the extracorporeal circuit, the patient was placed on veno-arterial ECMO with 8 F arterial and 12 F venous cannulae. ⋯ The circuit was dissected and significant clots found in both the venous bladder and oxygenator. In addition, approximately one-third of the membrane compartment had a 'fused' circumferential pattern of dessicated clot which interrupted blood path continuity. In conclusion, this report describes an unusual complication of the ECMO oxygenator that occurred during long-term extracorporeal life support which most likely resulted from a coagulopathy.

Experimental study of double-lumen, two-stage endotracheal tube during conventional mechanical ventilation in rabbits.
To evaluate the effects of a double-lumen, two-stage endotracheal tube on gas exchanges (ventilatory efficiency) during conventional mechanical ventilation, using a ventilator in rabbits. ⋯ Compared with the conventional endotracheal tube, the new double-lumen, two-stage endotracheal tube reduced Paco2 by decreasing anatomical deadspace in rabbits with normal and injured lungs under pressure control ventilation, thus enhancing ventilatory efficiency and reducing ventilator-induced injury.

Assessment of pulmonary function in the early phase of ARDS in pediatric patients.
Scant data are available on lung function in acute respiratory distress syndrome (ARDS) in pediatric patients. We measured respiratory mechanics by single-breath occlusion and maximum expiratory flow-volume curves by forced deflation in ten critically ill infants with clinical ARDS. Ten mechanically ventilated infants without lung disease served as the control group. ⋯ The inhomogeneous distribution of lung injury in ARDS restricts the validity of respiratory mechanics measurements that rely on a single-compartment model. However, the forced deflation technique allows accurate spirometric assessments of the severity of restrictive (and obstructive) lung function changes in intubated infants with severe ARDS. Such measurements can be incorporated into lung injury scoring systems to classify the severity of the disease process for the purpose of outcome evaluation and to evaluate the effect of therapeutic interventions.
