- Brief Summary
Induction of anesthesia is associated with risk of hypotension as anesthetic agents have cardiovascular depressant and vasodilatory effects . Ultrasound examination of inferior venacava in patients with spontaneous respiration has been recommended as anon invasive method for estimation of volume status .However IVC assessment has limitations in patients with abdominal distension and tenderness. In this study we intend to measure the preoperative diameter and collapsibility index of right infraclavicular axillary vein during spontaneous breathing and deep inspiration and then examine whether these parameters could predict hypotension after induction of general anesthesia
