Summary

This study compares two methods of giving spinal anesthesia—the median (midline) and paramedian (lateral) approaches—to see which one leads to fewer post-dural puncture headaches. About 142 adults having elective orthopedic or urology surgery will take part. The goal is to find a technique that reduces headache risk and severity after the procedure.
