Spinal Needles
Spinal needle tip design determines PDPH risk, CSF flow, and ease of insertion. Cutting needles (Quincke) slice dura, causing higher headache rates. Pencil-point needles (Whitacre, Sprotte, Gertie Marx) spread dural fibers, dramatically reducing PDPH. Choosing the right needle and gauge is essential for safe, successful spinal anesthesia.
