AbstractExtracorporeal membrane oxygenation therapy remains a life saving modality for neonates with cardiopulmonary disease that is unresponsive to conventional therapy. Vital to its success is the insertion and maintenance of appropriately sized vascular cannulas. Problematic insertion and accidental dislodgments can be life threatening. To determine the treatment and outcome of these complications, a survey of participating Extracorporeal Life Support Organization centers was undertaken. Venous cannulation complications (13 patients) were due to inadequate vein size or tearing during initial attempts at cannulation. Proximal and alternative site cannulation were used. Difficult arterial cannulations (seven patients) were most often due to creation of an intimal flap that was corrected by proximal cannulation of the same vessel. The 10 cases of accidental dislodgment were most often associated with changes in position. Despite copious hemorrhage in many instances, 6 of 10 patients survived with intact neurologic status. Methods for dealing with these life threatening cannula related complications are described.
