Timely administration of broad-spectrum antibiotics is a critical pillar in the resuscitation of patients with sepsis.  B-lactam antibiotics are an important class of antibiotics commonly administered to patients with sepsis.  Typically, B-lactam antibiotics are administered over 30 minutes, but optimal bactericidal activity requires the concentration of free drug to be above the MIC of the organism for 40-70% of the dosing interval.  In this podcast we discuss two recent publications that compare continuous infusions of B-lactam antibiotics with intermittent effusions in patients with sepsis.
