简要总结
This is a prospective study which aims to evaluate the predictive accuracy of subclavian vein collapsibility index for assessing the intravascular volume status of patients undergoing lower limb surgeries in spinal anaesthesia and compare it with inferior vena cava collapsibility index. The primary objective of the study is to calculate the sensitivity, specificity, positive predictive value and negative predictive value of subclavian vein collapsibility index for intravascular volume assessment and the secondary objective is to assess the correlation between subclavian vein collapsibility index and inferior vena cava collapsibility index. Therefore the study seeks to establish whether subclavian vein collapsibility index is feasible and reliable alternative to inferior vena cava collapsibility index particularly in situations where inferior vena cava visualisation is difficult.
