Observational Study
Effects of combined the trendelenburg and passive leg raising positions on the cross-sectional area of the right internal jugular vein.
The primary aim of this study was to assess the effects of a combination of the passive leg raising (PLR) and Trendelenburg positions on the cross-sectional area (CSA) of the right internal jugular vein (RIJV) using ultrasound measurement in awake patients. ⋯ Although the PLR + Trendelenburg position increased the jugular vein diameter relative to the supine position, its clinical usefulness is limited as this increase was still lower than that achieved with the Trendelenburg position alone.
