Study summary

Comparison between ultrasound measurement of IVCD-AOd index in prediction of post induction hypo tension

Read the detailed description

This study aims to evaluate the ability of preoperative ultrasound measurements IVC to aorta diameter index to predict post-induction hypotension in comparison with ultrasound measurements of the IVC collapsibility index.
