Official title
Prediction of Hypotension After Spinal Anesthesia in Cesarean Sections Using Non-Invasive Measurement Methods: Comparative Analysis of Perfusion Index, Pulse Variability Index, Tissue Oxygen Saturation and Tissue Hemoglobin Index
Overview
To compare the incidence of hypotension after spinal anesthesia and the values of perfusion index, pleth variability index, tissue oxygen saturation and tissue hemoglobin index between those who developed hypotension and those who did not develop hypotension over time.
Interventions
- Diagnostic test perfusion index
To compare the incidence of hypotension after spinal anesthesia and the values of perfusion index, pleth variability index, tissue oxygen saturation and tissue hemoglobin index between those who developed hypotension and those who did not develop hypotension over time.
Primary outcome measures
- tissue oxygen saturation [Time frame: 4 month]
- tissue hemoglobin index [Time frame: 4 month]
