This study evaluates the administration of beta-lactam antibiotics in extended infusion in hematological patients with febrile neutropenia after 5 days of treatment. The beta-lactam antibiotics analyzed are the following: piperacillin-tazobactam, cefepime and meropenem. Half of patients will receive the antibiotic in intermittent infusion, while the other half will receive it in extended infusion.
Febrile neutropenia (FN) is a very frequent complication in patients with hematological malignancies. It is associated with an important morbidity and mortality. Nowadays the use of betalactam antibiotics (BLA) in extended or continuous infusion (EI, CI) instead of intermittent infusion (II), has demonstrated a therapeutic success and lower mortality rate in critically ill intensive care patients. Neutropenic patients are a particular population since FN is assoicated with pathophysiological variations that compromise pharmacokinetic parameters of BLA, and may therefore, diminish their clinical efficacy. Information regarding the usefulness of BLA in EI in neutropenic hematologic patients is scarce.
The objective of this randomized clinical trial is to demonstrate the clinical superiority of the administration of BLA in EI compared to II in patients with FN.
