Pulmonary Diffusion of Antibiotics in Patients Admitted for ARDS Following SARS-CoV-2 Pneumonia

"These patients are put on VM as part of their care and present a suspicion of a 1st episode of PAVM for which a microbiological sample is taken and a probabilistic antibiotic therapy is started with the PIP-TAZ association (D0). A plasma PIP-TAZ assay will be performed 48 hours after the start of antibiotic therapy with PIP-TAZ. Blood urea will be measured and a mini-LBA (performed with a Combicatheter®) will be performed to measure PIP-TAZ and urea in the ELF.~On day 7 of the antibiotic therapy (last day of the planned antibiotic therapy), the same samples are taken and the same analyses are performed + bacteriology on the mini BAL. For patients for whom antibiotic therapy has been interrupted because of sterile samples, the samples taken at D7 will not be taken.~The clinical outcome of the patient will then be recorded until D60."
