Racial differences in withdrawal of mechanical ventilation do not alter mortality in neurologically injured patients.
Racial differences in withdrawal of mechanical ventilation (WMV) have been demonstrated among patients with severe neurologic injuries. We ascertained whether such differences might be accounted for by imbalances in socioeconomic status or disease severity, and whether such racial differences impact hospital mortality or result in greater discharge to long-term care facilities. ⋯ Surrogates of nonwhite neurologically injured patients chose WMV less often even after correcting for socioeconomic status and other confounders. This difference in end-of-life decision making does not appear to alter hospital mortality but may result in more survivors left in a disabled state.

Surgical rib fixation for flail chest deformity improves liberation from mechanical ventilation.
The goal of this study was to determine the impact of surgical rib fixation (SRF) in a treatment protocol for severe blunt chest trauma. ⋯ Surgical rib fixation resulted in a significant decrease in ventilator days and may represent a novel approach to decreasing morbidity in flail chest patients when used as a rescue therapy in patients with declining pulmonary status. Larger studies are required to further identify these benefits.

Indications and outcomes in children receiving renal replacement therapy in pediatric intensive care.
We aimed to describe patient characteristics, indications for renal replacement therapy (RRT), and outcomes in children requiring RRT. We hypothesized that fluid overload, not classic blood chemistry indications, would be the most frequent reason for RRT initiation. ⋯ Hemodynamic instability and multiorgan dysfunction syndrome are the most common clinical conditions associated with acute kidney injury in our population. In the population studied, the mortality was lower than previously reported in children and much lower than in the adult population.

Impairment of thrombin generation in the early phases of the host response of sepsis.
The purpose was to investigate the presence of hypercoagulability in the very early phase of the host response to an infection in the clinical course of sepsis and septic shock. ⋯ Patients with sepsis and febrile neutropenia present an impairment in thrombin generation from very early stages of their disease course. These results suggest that the procoagulant in vitro alterations described during sepsis do not necessarily translate into a clinically relevant systemic hypercoagulable state. These findings could help explain why treatment with systemic anticoagulants did not translate to clinical benefits in human sepsis and highlight the need for a better understanding of the hemostatic alterations in sepsis before new treatments targeting coagulation activation are developed.

Multicenter StudyAre written advance directives helpful to guide end-of-life therapy in the intensive care unit? A retrospective matched-cohort study.
The purpose of the study was to determine whether treatment preferences in patients' advance directives (ADs) are associated with life-supporting treatments received during end-of-life care in the intensive care unit (ICU). ⋯ Patients with ADs are less likely to receive cardiopulmonary resuscitation but otherwise receive similar life-sustaining treatments compared to matched patients without ADs. More research is needed to explore reasons for potential noncompliance with patient preferences.
