简要总结
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.
