Design outcomes

Primary

MeasureTime frame
To compare the predictive ability of inferior vena cava and Subclavian vein diameter and collapsibility index for detection of hypotension after induction of general anesthesia.Timepoint: Baseline blood pressure, every minute for the first 5 minutes, then every 2 minutes for the next 10 minutes (after induction of general anaesthesia)—

Secondary

MeasureTime frame
To compare the feasibility of subclavian vein and inferior vena cava diameter and collapsibility index in assessing post-induction hypotension. Timepoint: Before induction of general anaesthesia—
