Antibiotic- and Fluid-Focused Bundles Potentially Improve Sepsis Management, but High-Quality Evidence Is Lacking for the Specificity Required in the Centers for Medicare and Medicaid Service's Sepsis Bundle (SEP-1).
To address three controversial components in the Centers for Medicare and Medicaid Service's sepsis bundle for performance measure (SEP-1): antibiotics within 3 hours, a 30 mL/kg fluid infusion for all hypotensive patients, and repeat lactate measurements within 6 hours if initially elevated. We hypothesized that antibiotic- and fluid-focused bundles like SEP-1 would probably show benefit, but evidence supporting specific antibiotic timing, fluid dosing, or serial lactate requirements would not be concordant. Therefore, we performed a meta-analysis of studies of sepsis bundles like SEP-1. ⋯ Available studies support the notion that antibiotic- and fluid-focused sepsis bundles like SEP-1 improve survival but do not demonstrate the superiority of any specific antibiotic time or fluid volume or of serial lactate measurements. Until strong reproducible evidence demonstrates the safety and benefit of any fixed requirement for these interventions, the present findings support the revision of SEP-1 to allow flexibility in treatment according to physician judgment.

Case ReportsB-Mode Ultrasound Findings in a Patient With Suspected Pulmonary Gangrene.
Lung ultrasound has shown increasing diagnostic value in many lung diseases and has become an efficient tool in the management of dyspnea. In the present case report, we describe a new ultrasound feature of potential interest. ⋯ Lung ultrasound may help highlight pulmonary gangrene, a poorly-known disease, with this new ultrasonographic description. The next step will be to ascertain the relation between this new ultrasound feature and pulmonary gangrene and to assess how this bedside diagnosis could impact the prognosis of the disease.

Observational StudySupply Chain Delays in Antimicrobial Administration After the Initial Clinician Order and Mortality in Patients With Sepsis.
There is mounting evidence that delays in appropriate antimicrobial administration are responsible for preventable deaths in patients with sepsis. Herein, we examine the association between potentially modifiable antimicrobial administration delays, measured by the time from the first order to the first administration (antimicrobial lead time), and death among people who present with new onset of sepsis. ⋯ Delays in the first antimicrobial execution, after the initial clinician assessment and first antimicrobial order, are frequent and detrimental. Biases inherent to the retrospective nature of the study apply. Known biologic mechanisms support these findings, which also demonstrate a dose-response effect. In contrast to the elusive nature of sepsis onset and sepsis onset recognition, antimicrobial lead time is an objective, measurable, and modifiable process.
