简要总结
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.
