A comparative study of inferior vena cava Collapsibility index and brachial artery peak Systolic flow velocity variation with passive Leg raising in predicting hypotension after Induction of general anaesthesia

Abstract

BACKGROUND: Post induction hypotension is a fairly common yet avoidable complication in the perioperative period and is attributable to the volume status of the patient in most instances . Since most measures employed to predict hypovolemia are invasive , ultrasonography based non invasive indices such as IVC collapsibility index and brachial artery peak systolic flow variation with passive leg raise can be utilised . However ,evidence supporting the efficacy of velocity variation using brachial artery is still meak. OBJECTIVE: To compare IVC collapsibility index and brachial artery peak systolic flow velocity with passive leg raising in predicting hypotension after induction of general anaesthesia
