Jugular vein collapsibility index and shock indices (Shock index, Modified Shock Index, Diastolic Shock Index) may be useful in estimating post spinal hypotension in cesarean section operations. Evaluation on the accuracy and effectiveness of these indices can contribute to the early diagnosis and management of hypotension. The main purpose of this study is to evaluate the effectiveness of shock indices in predicting the possibility of post spinal hypotension in cesarean section operations.

Inclusion Criteria:

• Pregnant women between the ages of 18-45 who had a planned cesarean section and approved to participate in the study and to apply spinal anesthesia

Exclusion Criteria:

• Patients with Preeclampsia, Eclampsia, HELLP syndrome

Pregnant women between the ages of 18-45 who were scheduled for cesarean section and who gave consent to participate in the study and to apply spinal anesthesia will be included in this study.
