Prediction of Hypotension After Spinal Anesthesia in Cesarean Sections Using Non-Invasive Measurement Methods

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.

Treatment and study plan

Perfusion index

Diagnostic Test

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.

Other names: pleth variability index, tissue hemoglobin index, tissue oxygen saturation

Primary outcomes

  1. tissue oxygen saturation

    Time frame: 4 month

    which indicates an increase in local tissue perfusion

  2. tissue hemoglobin index

    Time frame: 4 month

    indicating vasodilation
