Critically ill patients admitted for acute brain injury are exposed to many heath-care associated infections such as ventilator associated pneumoniae (VAP). The PROHYVAP study, published in 2024 reported that a single dose of CEFTRIAXONE as an antibiotic prophylaxis could reduce the incidence of early VAP (VAP that occured between day 2 and day 7 of mechanical ventilation).
However, patients with acute brain injury also presented frequently augmented renal clearance (ARC), which could affect the pharmacokinetic and pharmacodynamic target attainment (PK/PD) of antibiotic prophylaxis.
This study aims to analyse the PK/PD target attainment after one dose of CEFTRIAXONE in critically ill patients with acute brain injury and to describe the effect of ARC on PK/PD target attainment during early VAP.
