Perfusion index as a predictor of hypotension following subarachnoid block in parturients with non-severe pre-eclampsia undergoing lower segment cesarean section

Background and Aims: Perfusion index, which assesses perfusion dynamics is used as a non‑invasive method in spinal anesthesia cases to detect the occurrence of hypotension. A Index value after hypotension common can be assessed. Methods: In this prospective double-blind observational study, 100 parturients were included. Baseline was recorded carried out with Injection bupivacaine 0.5% (hyperbaric), 10 mg at L3 - L4 / L2 intervertebral space. Fall Systolic Blood Pressure < 20 % baseline defined Chi-Square test independent sample t-test for statistical analysis. Spearman’s rank correlation coefficient applied assess between PI The receiver operating characteristic (ROC) curve mapped Results: 4.25 40.9% compared 94.6% > 4.25.
