Public Title of Study
|
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. |

Brief Summary
|
Hypotension in the peri operative period essentially implies organ hypoperfusion and hence must be evaluated and prevented. One third of all hypotensive episodes in major surgeries occur between the induction of anaesthesia and incision. General anaesthetic drugs due to vasodilatation or circulatory depression lead to hypotension, which could be more profound if there is hypovolemia as well. By predicting the occurrence of hypotension,hypovolemia can be corrected and catastrophic consequences can be avoided in high risk patients Hence, our aim is to predict hypotension following induction of anaesthesia by measuring internal jugular versus axillary vein diameter variation following passive leg raising test. |
