Background: Spinal anesthesia (SA) is commonly employed for elective cesarean
section (CS); however, it is frequently complicated by post-SA hypotension (PSAH),
which may adversely influence maternal and fetal outcomes. Objective: to determine
the predictive performance of the collapsibility indices of internal jugular vein (IJV),
inferior vena cava (IVC), and femoral vein (FV) in detecting PSAH CS. Methods: A
cross-sectional study was conducted at Benha University Hospital. Ultrasonographic
assessment of venous collapsibility indices was performed prior to SA in women
scheduled for elective CS. Hemodynamic parameters, including heart rate and mean
arterial pressure, were documented at three-minute intervals during the first 15
minutes following SA. Results: There were highly statistically significant differences
between patients with and without PSAH, and the mean collapsibility indices of the
internal jugular, inferior vena cava, and femoral veins demonstrated high sensitivity
and specificity in predicting PSAH. Conclusions: IJV, IVC, and FV collapsibility
indices were effective and reliable predictors of PSAH in pregnant women
undergoing CS, with FVCI demonstrating the highest specificity and sensitivity. |
