Brief Summary

This study aimed to evaluate the use of ultrasound in obstetric anesthesia, specifically for measuring epidural and intrathecal distances in pregnant women undergoing cesarean section. The relationship between skin-subdural distance (Ultrasound depth) and needle depth was assessed, and the accuracy of ultrasound in determining needle entry site, needle distance, trial attempts, and block success was examined. Additionally, complications such as paresthesia, lower back pain, and postoperative headache were queried and recorded.

EXPERIMENTAL

Regional block procedures were performed on all patients included in the study in a sitting position, using the most appropriate interspinous space among L3-L4-L5-S1. Ultrasonography was conducted using a convex probe in the paramedian and transverse planes, and the images were recorded. Regional (spinal and/or epidural) anesthesia was provided by entering the lumbar space identified with ultrasonography.

Other: The use of ultrasound in central blocks
