Nebulized antibiotics may be used to treat ventilator-associated pneumonia. In previous pharmacokinetic studies, lung interstitial space fluid concentrations have never been reported. The aim of the study was to compare intravenous and nebulized tobramycin concentrations in the lung interstitial space fluid, epithelial lining fluid, and plasma in mechanically ventilated sheep with healthy lungs. ⋯ Compared with intravenous tobramycin, nebulized tobramycin achieved higher lung interstitial fluid and epithelial lining fluid concentrations without increasing systemic concentrations.

Over the past decade, failure to rescue-defined as the death of a patient after one or more potentially treatable complications-has received increased attention as a surgical quality indicator. Failure to rescue is an appealing quality target because it implicitly accounts for the fact that postoperative complications may not always be preventable and is based on the premise that prompt recognition and treatment of complications is a critical, actionable point during a patient's postoperative course. ⋯ Although failure to rescue is believed to contribute to observed hospital-level variation in both surgical outcomes and costs, further work is needed to delineate the underlying patient-level and system-level factors preventing the timely identification and treatment of postoperative complications. Therefore, the goals of this narrative review are to provide a conceptual framework for understanding failure to rescue, to discuss various associated patient- and system-level factors, to delineate the reasons it has become recognized as an important quality indicator, and to propose future directions of scientific inquiry for developing effective interventions that can be broadly implemented to improve postoperative outcomes across all hospitals.
