Prospective observational study to compare Subclavian vein/infraclavicular axillary vein Collapsibility index with inferior venacava Collapsibility index (during spontaneous Breathing or deep inspiration) in predicting Hypotension after induction of general Anaesthesia

Abstract

Background: Intraoperative hypotension during general anesthesia leads to many postoperative complications which can be avoidable. In contrast with inferior vena cava, subclavian vein collapsibility index is found to be a better predictor of intravascular volume status.

Objectives: To compare the subclavian vein/infraclavicular axillary vein collapsibility index with Inferior vena cava collapsibility index (during spontaneous breathing or deep inspiration) in predicting hypotension after induction of general anesthesia.
