Secondary

Measure	Time frame
1.To compare the incidence of hypotension & vasopressor requirement. 2.To compare the time taken for regression of spinal block till T12 dermatome level.Timepoint: 1.To compare the incidence of hypotension & vasopressor requirement at baseline, time of spinal block, 2 mins after spinal block, 4 mins after spinal block & so on. 2.To compare the time taken for regression of spinal block till T12 dermatome level. Level of block to be assessed at 20 mins, 40 mins, 60 mins, 80 mins & 120 mins after administration of drug into subarachnoid space.	—
