Strong correlation between doppler snuffbox resistive index and systemic vascular resistance in septic patients.
To compare systemic vascular resistance index (SVRI) as measured by invasive transpulmonary indicator dilution (TPID) and non-invasive Doppler-derived resistive index in septic patients. ⋯ Using ultrasound to measure RI is a noninvasive, inexpensive, reliable method to evaluate peripheral vascular resistance in septic patients, and it is highly correlated with SVRI. In addition, SBRI can be used to evaluate peripheral circulatory disturbances in septic patients.

Creation of an empiric tool to predict ECMO deployment in pediatric respiratory or cardiac failure.
To create a real-time prediction tool to predict probability of ECMO deployment in children with cardiac or pulmonary failure. ⋯ Here, we present a tool to predict ECMO deployment among critically ill children; this tool will help create real-time risk stratification among critically ill children, and it will help with benchmarking, family counseling, and research.

To investigate the relationship between sex and mortality and whether menopause or the intensity of renal replacement therapy (RRT) modify this relationship in patients with severe septic acute kidney injury (AKI). ⋯ In a cohort of patients with sepsis and severe AKI, female sex was associated with improved survival. The relationship between sex and survival was not altered by menopausal status or RRT intensity.

Observational StudyComparison of learning outcomes for teaching focused cardiac ultrasound to physicians: A supervised human model course versus an eLearning guided self- directed simulator course.
Focused cardiac ultrasound (FCU) training in critical care is restricted by availability of instructors. Supervised training may be substituted by self-directed learning with an ultrasound simulator guided by automated electronic learning, enabling scalability. ⋯ Self-directed learning with ultrasound simulators may be a scalable alternative to conventional supervised teaching with human models.

Observational StudyUse of biomarkers in the prediction of culture-proven infection in the surgical intensive care unit.
The purpose of this study was to prospectively analyze the predictive role of classic predictors for suspected infection (temperature, WBC and derivatives) with two biomarkers, procalcitonin and lactate, on the incidence of culture-proven infection in the surgical intensive care unit (SICU). ⋯ The ability to utilize procalcitonin values in the diagnosis of culture-proven infection was not realized in this study. However, the association of admission peak procalcitonin values with admission peak lactate values identified a group of patients who were culture-negative for suspected infection. No other admission predictor was associated with culture-proven infection.
