Comparison of Pleth Variability Index vs. Diastolic Shock Index for Predicting Hypotension During Anesthesia Induction

Turkey (Türkiye)126 participantsStarted 2024-08-08

Plain-language summary

This study aims to explore the frequent occurrence of hypotension during anesthesia induction due to anesthetic drugs or fasting. Predicting this condition is important for patient safety and anesthesia management. The study examines two indices: the Pleth Variability Index (PVI), derived from pulse oximeter readings, and the Diastolic Shock Index (DSI), calculated using heart rate and diastolic blood pressure. While PVI is a well-known method, DSI has been less explored in predicting anesthesia-related hypotension. The study aims to compare the effectiveness of these two indices in forecasting hypotension during anesthesia induction.
