" Study of the Benefit of Nebulized Amikacin in the Treatment of Gram-negative Bacillus Pneumonia Acquired During Mechanical Ventilation in Patients Receiving Extracorporeal Membrane Veno-arterial Oxygenation "

Pneumonia are the most frequent infectious complication in patients on Extracorporeal Membrane Oxygenation Veno-arterial (ECMO-VA), with a treatment failure rate of around 40%, even though antibiotic therapy is tailored to the germs identified. One hypothesis to explain this particularly high failure rate is the reduced pulmonary blood flow associated with ECMO offloading of the heart. Although there are no data to date on the pulmonary penetration of antibiotics in patients undergoing VA-ECMO, this phenomenon of pulmonary hypoperfusion could contribute to altering the alveolocapillary diffusion of antibiotics, thereby reducing their concentration in the pulmonary parenchyma. Our hypothesis is that amikacin nebulization could increase bacterial clearance and, ultimately, limit treatment failure or recurrence of gram-negative bacilli (GNB) pneumonia in patients undergoing VA-ECMO.
