About this trial

This prospective observational study investigates the predictive value of anthropometric and hemodynamic indices for spinal anesthesia-induced hypotension (SAIH) during cesarean section. While spinal anesthesia is preferred for its rapid onset, SAIH remains a frequent complication risking maternal and fetal safety. The study enrolled parturients at Erciyes University, excluding those with hypertension or extreme weight/height. Preoperative measurements included BMI, waist circumference (WC), body roundness index (BRI), and modified shock index (MSI). Following standardized spinal anesthesia with hyperbaric bupivacaine (Harten's dosage), hemodynamic parameters and sensory block levels were monitored. This research aims to determine whether BRI and WC offer superior predictive utility compared with conventional markers such as BMI and MSI to enhance individualized risk assessment in obstetric anesthesia.

Incidence of Spinal Anesthesia-Induced Hypotension (SAIH)

The presence or absence of hypotension (binary variable) will be recorded. The predictive power of the independent variables (BMI, BRI, WC, MSI) for this condition will be evaluated using logistic regression. Nagelkerke's $R\^2$ was treated as a component of the analysis procedure, not as a measurement unit.

Time frame
From the time of spinal bupivacaine administration up to 30 minutes post-administration.
