    Spinal route of approach is the standard mode of regional anesthesia for conducting caesarean section is considered the standard mode of anaesthesia in caesarean section and it is considered safe, low cost with patient compliance. Spinal anesthesia induced sympathetic blockade, supine hypotension syndrome and low baseline vascular tone cause post spinal hypotension in the mothers. Perfusion index is a real time non-invasive parameter for early detection of this post spinal hypotension. Therefore the aim of this study was early prediction of anypost spinal hypotension and its degree of correlation withperfusion index. Materialsand Methods:A prospective observation study was conduct on200parturient, based on inclusion exclusion criteria devoid of any co-morbidities undergoing elective caesarean section subjected to spinal anesthesia. After routine investigations parturient were posted for elective caesarean section maintaining proper fasting guidelines. The perfusion index was measured with pulse oximeter at fixed time interval along with other vital parameters. The final data were analyzed with appropriate statistical software. Results:The parturient whose baseline finger perfusion index (P.I) is >3.5 have more chance of post spinal hypotension with a significance of p< 0.0001. Finger P.I with degree of decrease of SBP has positive correlation with highly significant value (r=0.7,p value<0.0001) whereas for MAP, it is highly significant but notpositively correlated(r=0.4, p value<0.0001). Conclusion:Finger perfusion index is an effective non- invasive predictor for the post spinal hypotension undergoing elective caesarean section. Additionally, the finger perfusion index is a reliable indicator of the extent to which systolic and mean arterial pressure decreases
