Internal Jugular Vein Collapsibility Index

Internal Jugular Vein Collapsibility Index: Assessment of internal jugular vein collapsibility index to predict hypotension after the induction of general anesthesia in geriatric patients undergoing laparoscopic colorectal surgeries.

Study summary

The internal jugular vein (IJV) collapsibility index has been proposed as a practical alternative of of the inferior vena cava collapsibility index (IVC-CI), as it is easily accessible using bedside ultrasonography. Several studies have demonstrated a correlation between IJV collapsibility and central venous pressure as well as right atrial pressure.
