Following induction of general anaesthesia there will be fall in blood pressure which can be predicted by measuring the diameter of veins like internal jugular vein ,axillary vein in the pre operative period so sudden fluctuations of blood pressure in intra operative period can be avoided.

Prediction of hypotension following induction of general anaesthesia by pre-anaesthesia ultrasonographic measurements of diameter variations of internal jugular vein versus axillary vein to modified passive leg raising:A prospective observational study - nil
