Novel Predictors of Post Spinal Hypotension in Cesarean Sections: Evaluating Jugular Vein Collapsibility Index and Shock Indices

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

Right Jugular Vein Collapsibility Index

Diagnostic Test

Ultrasonography will be used to evaluate the diameter of the jugular vein (minimum and maximum values) and carotid diameter. The jugular vein collapsibility index will be measured by the anesthesiologist using non-invasive ultrasonography. Jugular vein collapsibility index will be calculated using the measured diameters.

Primary outcomes

  1. Prediction of hypotension

    Time frame: 15 min

    To evaluate the ability of the jugular vein collapsibility index and shock indices (Shock index, Modified Shock Index, Diastolic Shock Index) to predict post spinal hypotension in cesarean section surgeries.
