"At the time of ventilator-associated pneumonia diagnosis, patients will receive an initial 4g loading dose of piperacillin-tazobactam with a continuous maintenance dose of 16g per day the first day of treatment. The dose of the piperacillin-tazobactam administered the following days will be adjusted to the renal function.~The antimicrobial treatment will be adjusted to the narrower-spectrum agent after the antimicrobial susceptibility determination for a total length of treatment of seven days."
