Design outcomes

Primary

MeasureTime frame
To measure Caval Aorta index (IVC:AO INDEX) and to compare the odds ratio between the groups for incidence of postspinal hypotensionTimepoint: In the preop holding area ultrasound will be performed and the caval aorta index will be measured. . Patient will receive spinal anasthesia.Hemodynamic parameters will be recorded every 2.5 minutes for the first 10 minutes and every 5 minutes till the end of surgery.

Secondary

MeasureTime frame
To measure IVC collapsibility index and to compare the odds ratio between the groups for the incidence of post spinal hypotension To compare the requirement of vasopressor between the groups Timepoint: In the preop holding area ultrasound will be performed and the ivc collapsibility index will be measured. . Patient will receive spinal anasthesia.Hemodynamic parameters will be recorded every 2.5 minutes for the first 10 minutes and every 5 minutes till the end of surgery.
