“…In VV ECMO in children weighing under 15 kg, drainage from the superior vena cava is recommended to obtain a better pump flow rate, because femoral drainage with a long, fine, resistant cannula in the right atrium results in a pressure drop that is deleterious for the functioning of the extracorporeal circulation [29,30]. In VA ECMO in children under 10 kg in weight, cervical cannulation is recommended [25].…”

The influenza H1N1 epidemics in 2009 led a substantial number of people to develop severe acute respiratory distress syndrome and refractory hypoxemia. In these patients, extracorporeal membrane oxygenation was used as rescue oxygenation therapy. Several randomized clinical trials and observational studies suggested that extracorporeal membrane oxygenation associated with protective mechanical ventilation could improve outcome, but its efficacy remains uncertain. Organized by the Société de Réanimation de Langue Française (SRLF) in conjunction with the Société Française d’Anesthésie et de Réanimation (SFAR), the Société de Pneumologie de Langue Française (SPLF), the Groupe Francophone de Réanimation et d’Urgences Pédiatriques (GFRUP), the Société Française de Perfusion (SOFRAPERF), the Société Française de Chirurgie Thoracique et Cardiovasculaire (SFCTV) et the Sociedad Española de Medecina Intensiva Critica y Unidades Coronarias (SEMICYUC), a Consensus Conference was held in December 2013 and a jury of 13 members wrote 65 recommendations to answer the five following questions regarding the place of extracorporeal life support for patients with acute respiratory distress syndrome: 1) What are the available techniques?; 2) Which patients could benefit from extracorporeal life support?; 3) How to perform extracorporeal life support?; 4) How and when to stop extracorporeal life support?; 5) Which organization should be recommended? To write the recommendations, evidence-based medicine (GRADE method), expert panel opinions, and shared decisions taken by all the thirteen members of the jury of the Consensus Conference were taken into account.

“…Au cours de l'ECMO VV chez l'enfant de moins de 15 kg, il est recommandé de drainer à partir de la veine cave supé-rieure, de façon à obtenir un meilleur débit de pompe, car un drainage par voie fémorale avec une canule longue mais fine et résistive en position intra-auriculaire droite entraîne une perte de charge délétère au fonctionnement de la circulation extracorporelle [29,30]. Au cours de l'ECMO VA chez l'enfant de moins de 10 kg, il est recommandé de réaliser les canulations au niveau cervical [25].…”

“…Hagen-Poiseuille equation states that the maximum flow is inversely proportional to the lumen length and directly proportional to the fourth power of the radius for a circular cross-section of lumen [12]. The radius and length of components were various, as a consequence of required quantities.…”

Relation Between Left Ventricular Unloading During Ecmo and Drainage Catheter Size Assessed by Mathematical Modeling

Abstract. The flow-dependent left ventricle overload is a well-known complication of the veno-arterial extracorporeal membrane oxygenation in a severe cardiogenic shock, which leads to a distension of the left ventricle and, frequently, to a severe pulmonary edema. Recently, an unloading of the left ventricle using a catheter inserted to the left ventricle and connected to the extracorporeal membrane oxygenation circuit has been proposed. The computational method was used to simulate the blood flow in the extracorporeal membrane oxygenation system with a drainage catheter incorporated to the left ventricle and connected to the inflow part of the extracorporeal membrane oxygenation circuit by a Y-shaped connector. The whole system was modelled in Modelica modelling language. The impact of various catheter sizes (from 5 Fr to 10 Fr) and extracorporeal blood flow values (from 1 L/min to 5 L/min) were investigated.In our simulation model, the extracorporeal blood flow only modestly affected the value of volume that was withdrawn from the left ventricle by a catheter. Conversely, the size of the drainage catheter was the principal factor responsible for the achievement of the adequate left ventricle decompression. A 10 Fr drainage catheter, inserted into the left ventricle and connected to the venous part of the ECMO system, presents a promising solution to the unloading of the left ventricle during a extracorporeal membrane oxygenation.
