Brief Summary

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.

Conditions

Regional Anesthesia Morbidity; Hemodynamic Instability; Shock; Cesarean Section Complications

Outcome Measures

Primary Outcomes (1)

• Prediction of hypotension

  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.

  15 min

Interventions

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.

Eligibility Criteria

• Age: 18 Years - 45 Years
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Probability Sample
