Clinical Trial
Extracorporeal membrane oxygenation for transport of hypoxaemic patients with severe ARDS.
Conventional inter-hospital transfer of patients with severe acute respiratory distress syndrome (ARDS) in need of extracorporeal membrane oxygenation (ECMO) may be risky and in severe hypoxaemic patients may be associated with cerebral hypoxia and death. Therefore, we began a phase 1 study to evaluate the feasibility, complications and outcome of inter-hospital transport of these patients using veno-venous ECMO. Eight patients with severe ARDS and a PaO2/FIO2 < 6.7 kPa at a PEEP > or = 10 cm H2O were placed on a mobile ECMO at the referring hospital. ⋯ No significant complications occurred. Six patients survived and were discharged from hospital; two patients died because of multiple organ failure. We conclude that initiation of ECMO in hypoxaemic patients before inter-hospital transfer is feasible and enables safe transport to an ECMO centre.

Review Case Reports
Pseudopulmonary embolism: acute respiratory distress in the syndrome of heparin-induced thrombocytopenia.
A 73-year-old man with myasthenia gravis was treated with daily plasmapheresis. During the course of treatment, the patient developed progressive thrombocytopenia and an episode of severe acute respiratory distress suggesting pulmonary embolism. ⋯ The time frame of clinical events suggests a heparin-mediated mechanism for both the thrombocytopenia and respiratory compromise. We conclude that acute respiratory distress may be the presenting manifestation of the syndrome of heparin-associated thrombocytopenia in patients treated with dialysis or apheresis.

Despite good results in neonates, extracorporeal membrane oxygenation (ECMO) is less well accepted in pediatric patients. Older children frequently undergo ECMO for severe bacterial, viral, or aspiration pneumonia and many have coexisting systemic sepsis. We reviewed data from a national registry to study the influence of sepsis on survival from ECMO. ⋯ Systemic sepsis does not independently influence survival in pediatric ECMO. This therapy should not be withheld solely because of sepsis, although neurologic complications may occur more frequently.

Case Reports
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.

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.
