Design outcomes

Primary

MeasureTime frame
To evaluate the efficacy of Perfusion Index (PI) and Pleth variability index (PVI) to detect hypotension following Spinal anaesthesiaTimepoint: Every 5 minute interval till end of surgery—

Secondary

MeasureTime frame
To study the hemodynamic changes in correlation with change in Perfusion index (PI) & Pleth Variability Index (PVI),and To study the effect of Ephedrine bolus on Perfusion index (PI) & Pleth Variability Index (PVI) to understand response to sympathomimetic drugs. Timepoint: At 5 minite intervals till end of surgery—
