Extracorporeal membrane oxygenation (ECMO) use has remarkably increased in recent years. Although ECMO has become essential for patients with refractory cardiac and respiratory failure, extracorporeal circulation (ECC) is associated with significant complications. Small-animal models of ECC have been developed and widely used to better understand ECC-induced pathophysiology. This review article summarizes the development of small-animal ECC models, including the animal species, circuit configuration, priming, perioperative procedures, cannulation, and future perspectives of small-animal ECMO models.

Abstract PDF

Background
Extracorporeal life support (ECLS) is an effective life-saving tool for patients in refractory cardiac or respiratory failure. Although transportation of patients on ECLS is challenging, it is necessary in some instances. We report our initial experience of transporting patients on ECLS.
Methods
The study period was between January 2004 and August 2013. We reviewed our ECLS database and identified four patients who were transported to our institution on ECLS. We excluded patients who were not transported by our ECLS team.
Results
There were no clinically significant events during transportation. ECLS indications included acute respiratory distress syndrome in two patients, stress-induced cardiomyopathy induced by pneumonia sepsis in one patient, and cardiac arrest caused by amyloid cardiomyopathy in another patient. One patient was transported by helicopter and three patients were transported in an oversized ambulance. Three patients were successfully weaned off ECLS and discharged without significant complications.
Conclusions
Inter-hospital transport can be safely performed by an experienced ECLS team. Successful transport may improve patient outcome and the ECLS programs of both referring and referral hospitals.

Abstract PDF

Thromboembolism in patients receiving extracorporeal membrane oxygenation (ECMO) support is a feared complication. Systemic anticoagulation during ECMO in patients with a massively dilated left ventricle (LV) and decreased LV systolic function is still debated. Hearin, we report a case of a 5-month old infant on ECMO support who had fatal thrombus formation in the massively dilated LV and a consequent thromboembolic event.

Abstract PDF: Pumpless extracorporeal interventional lung assist (iLA) is a promising respiratory rescue system permitting protective lung ventilation for severe respiratory failure. Herein, we report a case of prolonged iLA support with regards to a patient exhibiting severe hypercapnic respiratory failure. A 51-year-old female patient with metastatic endometrial carcinoma developed progressive hospital-acquired pneumonia and was intubated in order to restore respiratory failure. Despite maximal mechanical ventilator care, her clinical condition deteriorated due to severe respiratory acidosis. The iLA was performed for the management of refractory hypercapnia. The total duration of iLA support was 23 days without any vascular complications, however, she could not survive because of oxygenation failure.
