[Utility of the ECMO in patients with congenital diaphragmatic hernia].

At the moment the extracorporeal membrane oxygenation (ECMO) constitutes the last link in the therapeutic one of the handling of the respiratory failure in patients with Congenital Diaphragmatic Hernia (HDC). We presented our experience. From January 2001 we arrange the ECMO in neonative UCI. 76 HDC, 13 (3 rights and 10 lefts) they have needed ECMO (one in two occasions; altogether 14 procedures). Criteria of inclusion: refractory hypoxaemia, oxigenaction index > 40 and weight > 2 kg. 5 girls and 8 boys with gestacional age between 35 and 41 weeks (average: 38) and weight when being born between 2,300 and 3,500 grams (average 2,817). In 6 cases (5 transferred from other centers) the diagnosis was posnatal. Of the 7 with prenatal diagnosis, in 4 cases fetal therapy by means of traqueal occlusion had been made. Veno-venous in 8 and veno-arterial procedure in 5. Rank of duration: 68-606 hours, average of 228.35. The surgery has been made before the ECMO in 9 cases, 2 during and 1 later. In an occasion there was no surgery. The complications have been of hemorrágico type in one patient and infectious in three cases with sudden sepsis in one. Precocious mortality has been of 6 patients and delayed the 2 (total 61%). Although this procedure has the high morbi-mortality, it is necessary to consider that is patients very badly prognosis without another alternative (with mortality of the 100%). Multicentric studies are needed to establish indicators prognoses pre and postbirthdays.
