- Abstract
Objective: To determine the sensitivity and specificity of perfusion index in the right toe and index finger as a predictor of post-spinal hypotension in parturient undergoing Lower Segment caesarean Section (LSCS). Methods: 75 Parturient aged 18 to 35 years who were undergoing LSCS elective procedures, of ASA-II were included in the study. Intraoperative assessment of vital parameters including heart rate, NIBP, Respiratory rate, Sp02 and perfusion index at both finger and toe were recorded every 2 minutes till the 15th minute and then every 5 minutes till the end of the surgery. The data for the study was calculated using the SPSS 20.0 package program. Results: In this study, the mean age was 25.91 years (±3.82), heart rate 95.55 bpm (±14.9), Finger PI 5.64 (±3.49), Toe PI 3.38 (±3.36), and MAP 98.28 mmHg (±8.70). Using ROC analysis, baseline cutoffs for predicting hypotension were identified, Finger PI 3.55 (83.3% sensitivity, 51.1% specificity) and Toe PI 1.85 (80% sensitivity, 56% specificity). Conclusion: The Perfusion Index (PI) can be used as an effective tool for predicting hypotension in healthy parturients posted for elective caesarean section under subarachnoid block. Continuous monitoring of toe PIs during induction of spinal anaesthesia might help to predict the development of post-spinal hypotension and reflect the aorto-caval compression by the gravid uterus.
