In this review, Arendt and colleagues discuss the advantages of noncutting (pencil point or atraumatic) needles (e.g., Sprotte and Whitacre) over bevel-edge (cutting) needles (e.g., Quinke) in reducing the risk for postdural puncture headache (PDPH). The article, produced as a collaboration between anesthesiologists and neurologists, outlines the symptoms, incidence, and risk factors for PDPH and summarizes studies supporting the significant reduction in PDPH (by about 35% in neurologic procedures) when using noncutting versus cutting needles.
Some experiments have shown that, compared with cutting needles, noncutting needles make more-complex lesions in dura, but that less CSF leaks out. As the authors note, most studies involve anesthesiol…
