Observational StudyCarotid systolic flow time with passive leg raise correlates with fluid status changes in patients undergoing dialysis.
Corrected carotid systolic flow time (CFTc) has been proposed as a measure of volume status in acutely ill patients. This study endeavors to determine whether the change in CFTc with passive leg raise (PLR) maneuver correlates with volume status changes. Dialysis patients at Kingston General Hospital (Kingston, Canada) underwent point-of-care carotid ultrasonography at the beginning and the end of dialysis. ⋯ Particularly, in our sample of patients, a 30milliseconds increase in CFTc with PLR predicted the post-dialysis volume state (LR+=11) whereas an increase of less than 20milliseconds argued against it (LR-=0.079). The assessment of CFTc pre- and post-PLR correlates with intravascular volume changes in patients undergoing dialysis. Alternative to the currently available bedside modalities, this technique is non-invasive, objective, simple to perform at the bedside, and reversible with respect to volume challenge.

Filtering authentic sepsis arising in the ICU using administrative codes coupled to a SIRS screening protocol.
Using administrative codes and minimal physiologic and laboratory data, we sought a high-specificity identification strategy for patients whose sepsis initially appeared during their ICU stay. ⋯ Selected administrative codes coupled to SIRS criteria and applied to patients admitted to ICU can yield up to 94% authentic sepsis patients. However, only 1/3 of patients thus identified appeared to become septic during their ICU stay. Studies that depend on high-intensity monitoring for description of the time course of sepsis require clinician review and verification that sepsis initially appeared during the monitoring period.

Acute kidney injury is an independent risk factor for myocardial injury after noncardiac surgery in critical patients.
Myocardial injury after noncardiac surgery (MINS) contributes to mortality and morbidity. However, risk factors accelerating its development remain unclear. The aim of this study was to identify the incidence and risk factors of MINS. ⋯ The incidence of MINS in critical patients is high. Postoperative AKI is an independent risk factor of MINS in critical patients. It is recommended that postoperative kidney functions be routinely assessed in all critical patients after noncardiac surgery.
