Details and patient eligibility

About

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a life-support technique used in patients with most severe acute respiratory distress syndrome (ARDS). ARDS is a life-threatening form of respiratory failure associated with a mortality rate of approximately 40-45%.Despite several studies confirming a real benefit of the use of ECMO in patients with ARDS who are unresponsive to conventional management, ECMO is still a complex and costly treatment that can be exposed to potential complications, such as nosocomial infections (NI).

Full description

Noteworthy, the most frequent NIs occurring during VV-ECMO are pneumonia (>40%) and, secondly, blood-stream infections (3-18%). The situation is more challenging for Gram-negative bacilli: more than one-half of the Escherichia coli and more than one-third of the Klebsiella pneumoniae isolates were resistant to at least one antimicrobial group. Of note, an alarming increase in carbapenem resistance has been reported in several species, including K. pneumoniae (7.9% of isolates), P.aeruginosa (16.5% of isolates) and A. baumannii (>30% of isolates).

In fact, the isolation of MDROs has been shown to be an independent risk of death and of subsequent infections not only in critically ill patients but also in those patients requiring VV-ECMO (mortality rate between 56-68%). However, data are still conflicting about the exact incidence of multidrug resistant organisms (MDRO) during VV-ECMO and the impact on short- and mid-term outcomes.
