Use of a tracheal dilator for percutaneous insertion of 27F and 31F Avalon© dual-lumen cannulae for veno-venous extracorporeal membrane oxygenation in adults.

ABSTRACT

Veno-venous extracorporeal membrane oxygenation can be performed either by two cannulae or by a single dual-lumen cannula. The dual-lumen cannulation configuration offers multiple advantages it avoids the femoral site which may be at greater risk of infection, it improves patient mobility, eases prone positioning and greatly reduces recirculation. The Avalon was the first commercially available dual-lumen cannula for adults. It has gained much popularity, but, for more than a year now, the adult vascular access kit with the 30Fr dilator has been discontinued in the United Kingdom. In this article, we share our experience with an alternative insertion method, using a percutaneous dilatational tracheostomy kit. This off-label use of the tracheostomy dilator appears to be safe. It may allow the continuing use of Avalon dual-lumen cannulae while waiting for a more permanent solution to be provided by the manufacturer.
