ReviewUrine Electrolytes in the Intensive Care Unit: From Pathophysiology to Clinical Practice.
Assessment of urine concentrations of sodium, chloride, and potassium is a widely available, rapid, and low-cost diagnostic option for the management of critically ill patients. Urine electrolytes have long been suggested in the diagnostic workup of hypovolemia, kidney injury, and acid-base and electrolyte disturbances. ⋯ To clarify their potential role in managing critical patients, we reviewed existing evidence on the use of urine electrolytes for diagnostic and therapeutic evaluation and assessment in critical illness. This review will describe the normal physiology of water and electrolyte excretion, summarize the use of urine electrolytes in hypovolemia, acute kidney injury, acid-base, and electrolyte disorders, and suggest some practical flowcharts for the potential use of urine electrolytes in daily critical care practice.

Airway Rupture Caused by Double-Lumen Tubes: A Review of 187 Cases.
The double-lumen tubes (DLTs) are the most widely used devices to provide perioperative lung isolation. Airway rupture is a rare but life-threatening complication of DLTs. The primary aim of this review was to collect all cases reported in the literature about airway rupture caused by DLTs and to describe the reported possible contributors, diagnosis, treatment, and outcomes of this complication. ⋯ Most patients were treated with surgical repair (n = 147, 78.6%). The mortality of the patients with airway rupture by DLTs was 8.8%. Age, sex, site of rupture, diagnosis timing, and method of treatment were not found to be associated with mortality.

Despite a recent surge of interest in physician well-being, the discussion remains diffuse and often scattered. Lingering questions of what wellness entails, how it is personally applicable, and what can be done, remain pervasive. In this review, we focus on policy-level, institutional and personal factors that are both obstacles to wellness and interventions for potential remedy. ⋯ These include medical liability and licensure policy, peer support constructs, electronic health record optimization, and personal wellness strategies. Where sufficient data exists, we highlight areas specific to anesthesiology. Overall, we offer a pragmatic framework for addressing this critical concern at every level.

Observational StudyNeither Preoperative Pulse Pressure nor Systolic Blood Pressure Is Associated With Cardiac Complications After Coronary Artery Bypass Grafting.
Increased pulse pressure has been associated with adverse cardiovascular events, cardiac and all-cause mortality in surgical and nonsurgical patients. Whether increased pulse pressure worsens myocardial injury and dysfunction after cardiac surgery, however, has not been fully characterized. We examined whether cardiac surgical patients with elevated pulse pressure are more susceptible to myocardial injury, dysfunction, cardiac-related complications, and mortality. Secondarily, we examined whether pulse pressure was a stronger predictor of the outcomes than systolic blood pressure. ⋯ Elevated preoperative pulse pressure was associated with a modest increase in postoperative troponin-T concentrations, but not postoperative cardiovascular complications or in-hospital mortality in patients having CABG. Pulse pressure was not a better predictor than systolic blood pressure.
