Randomized Controlled Trial Comparative Study Clinical Trial
Postmyelography headache rates with Whitacre versus Quincke 22-gauge spinal needles.
To compare the postdural puncture headache (PDPH) rates after myelography with use of 22-gauge Whitacre (blunt tip) versus standard 22-gauge Quincke (bevel-tip) spinal needles. ⋯ The Whitacre needle is associated with an equal or lower PDPH risk; the lack of statistical significance is most likely related to sample size. Further study is necessary to determine whether the decreased PDPH rate justifies the added difficulty associated with use of the Whitacre needle.
