- Primary Outcome Measures
Name Time Method To assess the ability of ultrasonographic measurement of subclavian vein -diameter,collapsibility index to predict hypotension after induction of general anaesthesiaTimepoint: mean arterial pressure and heart rate at 2,4,6,8,10 minutes after induction
- Secondary Outcome Measures
Name Time Method To assess the ability of ultrasonographic measurement of inferior vena cava-maximum diameter,collapsibility index to predict hypotension after induction of general anaesthesia.Timepoint: mean arterial pressure,heart rate 2,4,6,8,10 minutes after induction;To compare the predictive power of inferior vana cava collapsibility index to subclavian vein collapsibility index in predicting general anaesthesai induced hypotensionTimepoint: mean arterial pressure,heart rate 2,4,6,8,10 minutes after induction;to compare time taken to obtain data from inferior vena cava and subclavian veinTimepoint: before induction of general anaesthesia
