Design outcomes

Primary

Measure	Time frame
To compare IVCCI AND IVC:AO index in predicting the incidence of post spinal anaesthesia hypotensionTimepoint: First 40 minutes from the time of giving spinal anaesthesia at every 2 minutes interval	—

Secondary

Measure	Time frame
To compare the IVCCI & IVC:AO index with the total volume of fluid given during surgeryTimepoint: First 40 minutes from the time of giving spinal anaesthesia at every 2 minutes interval;To compare the IVCCI & IVC:AO index with the volume of intravenous fluid infused before administering spinal anaesthesiaTimepoint: First 40 minutes from the time of giving spinal anaesthesia at every 2 minutes interval;To compare the number of hypotensive episodes occuring in a patient during surgeryTimepoint: First 40 minutes from the time of giving spinal anaesthesia at every 2 minutes interval;To evaluate & compare the requirement & total dose of vasopressors used during the surgeryTimepoint: First 40 minutes from the time of giving spinal anaesthesia at every 2 minutes interval	—
