Review Meta AnalysisPrognostic value of extravascular lung water index in critically ill patients: a systematic review of the literature.
The prognostic value of extravascular lung water (EVLW) has been widely investigated; however, a wide range of its predictive accuracy has been reported. ⋯ The EVLWI appears to be a good predictor of mortality in critically ill patients.

ReviewLiberation of neurosurgical patients from mechanical ventilation and tracheostomy in neurocritical care.
Neurosurgical patients commonly require mechanical ventilation and monitoring in a neurocritical care unit. There are only few studies that specifically address the process of liberation from mechanical ventilation in this population. Patients who remain ventilator or artificial airway dependent receive a tracheostomy. ⋯ In this article, we review the general principles of liberation and the current literature as it pertains to neurosurgical patients with primary brain injury. The criteria for "readiness of extubation" include a combination of neurologic assessment, hemodynamic, and respiratory parameters. Future studies are required to better assess indicators for extubation readiness, evaluate the predictors of extubation failure in brain-injured patients, and define the most appropriate timing for a tracheostomy.

Early bacterial genome detection in body fluids from patients with severe sepsis: a pilot study.
The purpose of this study is to evaluate the feasibility and interest of real-time polymerase chain reaction (RT-PCR) testing for bacterial genomes in body fluids other than blood in patients with acute severe sepsis. ⋯ Our results indicate that direct PCR testing may improve the detection of bacteria in body fluids other than blood in patients with acute severe sepsis.
