Dosage of antipseudomonal antibiotics in patients with acute kidney injury subjected to continuous renal replacement therapies

Critically ill patients are often affected by infections produced by Pseudomonas, which can be a cause of sepsis and renal failure. Early and adequate antibiotic treatment at correct dosage levels is crucial. Acute kidney injury is also frequent in critically ill patients. In those patients who require renal replacement therapy, continuous techniques are gaining relevance as filtering alternatives to intermittent hemodialysis. It must be taken into account that many antibiotics are largely cleared by continuous renal replacement therapies (CRRT). The aim of this review is to assess the clinical evidence on the pharmacokinetics and dosage recommendations of the main antibiotic groups used to treat Pseudomonas spp. infections in critically ill patients subjected to CRRT.
