Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Many previous studies have investigated the ability of various methods such as passive leg raising test , and inferior vena cava collapsibility index in predicting post-spinal hypotension, but none of them have succeeded in obtaining a good predictive value.

Our study aims to combine the passive leg raising test with the inferior vena cava distensibility index to aid in predicting post-spinal hypotension in elderly undergoing infra-umbilical surgeries.
