Design outcomes

Primary

MeasureTime frame
Hypotension after subarachnoid block in immediately lying down, lying down after one minute sitting position and lying down after two minutes sitting position groups. Parameters such as heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, oxygen saturation of blood will be measured.Timepoint: Time in minutes, At One minute for first ten minutes, every two minutes for next ten minutes, for every five minutes till the end of surgery.—

Secondary

MeasureTime frame
To evaluate the highest level of sensory block in all three groups. To determine the time taken to reach highest sensory block in all three groups. To determine the ephedrine requirements in all three groups.Timepoint: Time in seconds for sensory block and motor block.—
