Abstract
OBJECTIVE: We report a single centre experience of neonatal respiratory ECMO using the Avalon® double-lumen venous cannula and compare it with reports in the literature. RESULTS: Between 2008 and 2012, the Avalon® cannula was used in 72 neonates: median age at cannulation was 1.8 days (IQR 1.2-2.8 days) and bodyweight 3.4 Kg (3.0-3.7 Kg). Meconium aspiration syndrome (61.1%), persistent hypertension of the newborn (25%) and congenital diaphragmatic hernia (5.6%) were the most common diagnoses. Complications occurred in 19 patients (26.4%): cannula site bleeding in 6 (8.3%), the cannula perforating the right atrial wall and requiring emergency midline sternotomy in 5 (6.9%) and the cannula needing repositioning in 3 (4.2%). Overall survival at discharge or transfer to the referring hospital was 88.8%. Successful wean off ECMO occurred in 68 patients (94.4%) after a median of 90.5 hours (63.4-136.11). ECMO support was withdrawn in 4 patients (5.6%). CONCLUSIONS: The Avalon® dual-lumen veno-venous cannula can be used for respiratory ECMO in the neonatal population. However, as the incidence of right atrial perforation is not negligible, we suspended its used in this group of patients.
