BD® Whitacre needles yield a distinct tactile "click" or "pop" as the pencilpoint penetrates the dura, alerting the clinician of proper placement. Pencil-point needles like the BD® Whitacre spinal needles have been shown to minimize the risk of PDPH compared to larger gauge, cutting-point needles. BD® Whitacre spinal needles’ clear hubs enable anaesthesiologists to visualize CSF for proper needle placement. Precision-formed side hole helps directional flow of anesthetic agents and helps reduce the possibility of straddling the dura.
