Spinal anesthesia is commonly used for cesarean section and provides effective anesthesia with rapid onset. However, the spread of spinal anesthesia may vary among pregnant women due to physiological and anatomical changes during pregnancy. Increased intra-abdominal pressure and abdominal circumference may influence cerebrospinal fluid dynamics and affect the level of sensory block achieved after spinal anesthesia. This prospective observational study aims to evaluate the relationship between intra-abdominal pressure, abdominal circumference, and the maximum sensory block level following spinal anesthesia in pregnant women undergoing cesarean section. Intra-abdominal pressure and abdominal circumference will be measured before surgery, and sensory block levels and hemodynamic parameters will be assessed after spinal anesthesia. The findings of this study may help to better understand factors affecting spinal block spread in pregnant patients.
