Evaluation of the effectiveness of Pleth Variability Index (PVI) and Internal Jugular Vein Collapsibility Index (IJV-CI) measurement methods in predicting hypotension following spinal anesthesia
Abstract
Aims: Hypotension following spinal anesthesia is a significant issue in clinical practice. The aim of this study is to evaluate the efficacy of pleth variability index (PVI) and internal jugular vein collapsibility index (IJV-CI) in predicting the risk of hypotension that may develop in patients undergoing spinal anesthesia while breathing spontaneously.
Methods: After ethics committee approval, 116 patients scheduled for elective orthopedic surgery in the supine position under spinal anesthesia were included. Hypotension was defined as a drop in mean arterial pressure (MAP) below 60 mmHg or more than 20% below the baseline value. Patients who developed hypotension were designated as Group A, and those who remained normotensive as Group B. Preoperative and intraoperative PVI and IJV-CI values were measured for all patients and effectiveness of these values in predicting the risk of hypotension compared.
Results: Hypotension was observed in 69 (59.5%) patients. No statistically significant differences were observed between the groups in the comparison of PVI, and IJV-CI values at any time interval. No correlation between MAP values and PVI, and IJV-CI values at baseline (T0) and post-spinal block (T1) time points was identified.
Conclusion: Our findings demonstrated that neither pleth PVI nor IJV-CI exhibited significant efficacy in predicting hypotension among spontaneously breathing patients.
