Design outcomes

Primary

MeasureTime frame
To assess whether the ultrasonographic measurement of Subclavian vein diameter changes by passive leg rising will be able to predict hypotension after induction of general anaesthesia in patients of head and neck malignancies.Timepoint: up to 10 minutes after induction of anaesthesia—

Secondary

MeasureTime frame
To assess the predictive ability of subclavian vein collapsibility index for the incidence of post-induction hypotension in patients of head and neck malignanciesTimepoint: upto 10 minutes after induction of anaesthesia;To assess the predictive maximum diameter of subclavian vein in passive leg rising position for the incidence of post-induction hypotension in patients of head and neck malignanciesTimepoint: upto 10 minutes after induction of anaesthesia—
