Verification of endotracheal tube placement using electrical stimulation through electrodes placed on the endotracheal tube cuff.
Current methods for verification of endotracheal intubation can fail, particularly in emergency settings. We investigated whether a verification method using electrical stimulation through electrodes placed on the endotracheal tube cuff could distinguish endotracheal and esophageal intubations in an experimental setting. ⋯ Electrical stimulation through electrodes placed on the endotracheal tube cuff produced remarkably greater increases in cuff pressure in esophageal intubations than in tracheal intubations in an experimental setting.

CommentAssociation of plasma chloride values with acute kidney injury in the critically ill - a prospective observational study.
Chloride-rich fluids have been found to associate with an increased risk for acute kidney injury (AKI) among intensive care unit (ICU) patients. Studies evaluating the association of plasma chloride (Cl) with the development of AKI are few. We hypothesized that higher plasma Cl is associated with an increased risk for the development of AKI. ⋯ More than three of four critically ill patients had hyperchloremia and 1 of 10 had its severe form. Higher time-weighted mean chloride was independently associated with an increased risk for AKI.

Observational StudyIs internal jugular vein extensibility associated with indices of fluid responsiveness in ventilated patients?
Ultrasound of the inferior vena cava provides rapid and non-invasive assessment of fluid responsiveness. We hypothesized that the extensibility of the internal jugular vein (IJV) as well reflects intravascular volume state. We assessed IJV dimensions together with pulse pressure variation (PPV) as dynamic index for fluid responsiveness in mechanically ventilated patients. ⋯ Ultrasound of the IJV and PPV as a dynamic index for fluid responsiveness can be associated under certain defined conditions. Whether or not ultrasound of the IJV can be useful to predict patient intravascular volume state should be further studied using invasive cardiac output monitoring.

CommentNationwide incidence of serious complications of epidural analgesia in the United States.
This study aimed to describe the incidence and risk factors of in-hospital spinal hematoma and abscess associated with epidural analgesia in adult obstetric and non-obstetric populations in the United States. ⋯ This large nationwide data analysis reveals that the incidence of epidural analgesia-related complications is very low in obstetric population epidural analgesia and much higher in patients having vascular surgery.
