"Ultrasound vs. Landmark Technique for Spinal Anesthesia in Obese Women Undergoing Cesarean Section"

The goal of this clinical trial is to evaluate whether the ultrasound-assisted technique improves the accuracy and safety of spinal anesthesia compared to the traditional landmark technique in obese women undergoing a cesarean section. The main questions it aims to answer are: Does the ultrasound-assisted technique reduce the number of needle attempts required for successful spinal anesthesia? Does the ultrasound-assisted technique decrease the incidence of post-dural puncture headache (PDPH) and chronic low back pain at the needle insertion site? Does the ultrasound-assisted technique reduce procedure time compared to the landmark technique? Participants will: Receive spinal anesthesia using either the ultrasound-assisted technique or the traditional landmark technique for cesarean section. Be monitored for the number of needle attempts, procedure time, and any post-operative complications such as PDPH or low back pain. Follow up for three months after the procedure to assess any long-term effects, including chronic low back pain and quality of life.
