Design outcomes

Primary

MeasureTime frame
To predict the incidence of post spinal hypotension from toe perfusion index of lower segment cesarean section patients.Timepoint: Baseline and post spinal anesthesia first 30 minutes—

Secondary

MeasureTime frame
To explore the correlation between toe Perfusion index and spinal hypotension and determine cut off value if any through ROC curves. To assess the relationship between changes in the perfusion index in the right and left toe and incidence of post spinal hypotension To analyse the differential perfusion index of upper limb and lower limb Timepoint: Baseline and post spinal anesthesia first 30 minutes—
