Design outcomes

Primary

MeasureTime frame
To evaluate preoperative inferior vena cava collapsibility index in predicting the occurrence of spinal-induced hypotension in patients undergoing infraumbilical surgery under spinal anesthesia.Timepoint: From Base line to surgery procedure at Pre operative time and intra operative time.—

Secondary

MeasureTime frame
1. To assess the requirement of vasopressors in patients with varying inferior vena cava collapsibility index values. 2. To calculate the total time for inferior vena cava parameters on UltrasonographTimepoint: From Base line to surgery procedure at Pre operative time & intra operative time.—
