Design outcomes

Primary

Measure	Time frame
preoperative prediction of post spinal hypotension in elderly patients undergoing lower limb surgeries using IVCCI area under receiver operating characteristic curves (AUROC) and caval aorta index (IVC/Ao)	—

Secondary

Measure	Time frame
• compare the predictive efficacy of these two parameters for predicting PSH. • relationship between the IVCCI and the maximum MAP reduction percentage after spinal anesthesia. • relationship between IVCDmax/Ao and the maximum reduction in MAP following induction of spinal anesthesia and the incidence of post-induction hypotension • Standard monitoring (electrocardiogram, blood pressure measurements preoperative and for 15 min post induction of spinal anesthesia, and peripheral oximeter readings) PSH was defined as a decrease in SBP by more than 20% of the baseline value or an absolute value of SBP less than 90 mmHg or MAP less than 60 mmHg . • Total fluid requirement • Vasoactive treatment requirement	—
