Interventions

  • Internal Jugular Vein Collapsibility Index Measurement — OTHER
    Preoperative ultrasonographic measurement of the internal jugular vein collapsibility index (IJVCI) performed before spinal anesthesia in preeclamptic parturients (gestational age ≥28 weeks) undergoing cesarean delivery classified as Lucas category 3-4.

Study Details

This prospective, single-center observational study aims to evaluate the predictive value of the internal jugular vein collapsibility index (IJVCI) for spinal anesthesia-associated hypotension in preeclamptic parturients (gestational age ≥28 weeks) undergoing cesarean delivery classified as Lucas category 3-4. Preoperative IJVCI will be measured using ultrasonography before spinal anesthesia during spontaneous and deep respiration. The incidence of hypotension within the first 20 minutes after spinal anesthesia will be recorded. The diagnostic performance of IJVCI in predicting hypotension will be analyzed.

Arms

  • Arm: Preeclamptic Parturients Undergoing Cesarean Section
    Preeclamptic pregnant women aged 18-45 years with ASA physical status II-III and gestational age ≥28 weeks who are scheduled for cesarean delivery under spinal anesthesia, with cesarean urgency classified as Lucas category 3-4. Preoperative internal jugular vein collapsibility index (IJVCI) will be measured using ultrasonography before spinal anesthesia, and participants will be followed for the development of spinal anesthesia-associated hypotension within the first 20 minutes after spinal anesthesia.
