AI Prediction of Post-Induction Hypotension in Cesarean Sections With Spinal Anesthesia

After standard monitoring, the patient is placed in a sitting position for site marking and administration of anesthesia. The line connecting the upper border of the right and left iliac crests through conventional palpation of anatomical landmarks (Tuffier line) is identified as the entry point at the L3-L4 interspinous space or L2-L3 interspace. For patients in whom spinal entry is successful, spinal anesthesia is provided with the appropriate dose and types of local anesthetics (intrathecal 10-12 mg bupivacaine with the addition of 15-25 mcg fentanyl). After completing the procedure and placing the patient in the supine position, the block level is determined 10 minutes post-procedure using the ice test/pinprick test. Blocks reaching the T4-T6 level are considered successful.

Preoperatively, syndecan-1 serum levels will be investigated from the blood sample taken before cesarean section.
