Phase angle (PA) is interpreted as an indicator of cell membrane integrity and a prognostic indicator in some clinical situations. This study aims to evaluate PA as a prognostic marker in critically ill patients admitted to the intensive care unit (ICU) and associate this marker with length of hospital stay, mortality, and clinical scores. ⋯ PA seems to be a good prognostic marker for patients without sepsis. The weak correlation between PA and APACHE II score and the lack of association with other clinical outcomes are limitations for interpreting the prognostic value of PA in the entire study sample.

Nasogastric feeding tube (NGT) placement is a common practice performed in intensive care units (ICUs). Complications due to the improper placement of NGT are well known. In this prospective descriptive study, the effectiveness of ultrasound (US)-guided NGT placement was investigated. ⋯ This study revealed that passing of the NGT through the esophagus could be visualized at a high rate in real-time US among ICU patients. These data suggest that ultrasonographic visualization of the upper esophagus during NGT insertion can be used as an adjuvant method for confirmation of correct placement.
