Multicenter StudySevere abnormalities in microvascular perfused vessel density are associated to organ dysfunctions and mortality and can be predicted by hyperlactatemia and norepinephrine requirements in septic shock patients.
The aims of this study are to determine the general relationship of perfused vessel density (PVD) to mortality and organ dysfunctions and to explore if patients in the lowest quartile of distribution for this parameter present a higher risk of bad outcome and to identify systemic hemodynamic and perfusion variables that enhances the probability of finding a severe underlying microvascular dysfunction. ⋯ Perfused vessel density is significantly related to organ dysfunctions and mortality in septic shock patients, particularly in patients exhibiting more severe abnormalities as represented by the lowest quartile of distribution for this parameter. The presence of hyperlactatemia and high norepinephrine requirements increases the odds of finding a severe underlying microvascular dysfunction during a sublingual microcirculatory assessment.

Multicenter StudyImpaired gastrointestinal transit and its associated morbidity in the intensive care unit.
To determine the proportion of critically ill adults developing impaired gastrointestinal transit (IGT) using a clinically pragmatic definition, its associated morbidity and risk factors. ⋯ Traditional definitions of constipation or ileus in intensive care unit patients are simplistic and lack clinical relevance. Pragmatically defined IGT is a common complication of critical illness and is associated with significant morbidity. Future interventional studies for IGT in critically ill adults should use a more clinically relevant definition and evaluate energy deficits and lengths of stay as clinically relevant outcomes.

Novel device (AirWave) to assess endotracheal tube migration: a pilot study.
Little is known about endotracheal tube (ETT) migration during routine care among critically ill patients. AirWave is a novel device that uses sonar waves to measure ETT migration and obstructions in real time. The aim of the present study is to assess the accuracy of the AirWave to evaluate ETT migration. In addition, we determined the degree of variation in ETT position and tested whether more pronounced migration occurs in specific clinical scenarios. ⋯ The AirWave may provide useful information regarding ETT migration and obstruction in real time.

Capture-mark-recapture as a tool for estimating the number of articles available for systematic reviews in critical care medicine.
Systematic reviews are an important knowledge synthesis tool for critical care medicine clinicians and researchers. With new literature available each day, reviewers must balance identifying all relevant literature against timely synthesis. We therefore sought to apply capture-mark-recapture, a novel methodology, to estimate the population of articles available for a systematic review of effective patient rounding practices in critical care medicine. ⋯ The capture-mark-recapture technique can be applied to systematic reviews in critical care medicine with heterogeneous study methodologies to estimate the population of articles available. Capture-mark-recapture may help clinicians who use systematic reviews to estimate search completeness and researchers who perform systematic reviews to develop more efficient literature search strategies.

Multicenter StudyRapid response teams, do not resuscitate orders, and potential opportunities to improve end-of-life care: a multicentre retrospective study.
Rapid response teams (RRTs) were created to stabilize acutely ill patients on the ward, but recent studies suggest that RRTs may improve end-of-life care (EOLC). To learn more about the role of the RRT in EOLC at our institutions, we conducted a retrospective review. ⋯ RRT consultation is an important milestone for many patients approaching EOL. RRTs frequently participate in EOL discussions and decision-making, but they may miss opportunities to facilitate EOLC.
