Hadassah Physicians’ Study Supports Novel Needle for Spinal Fluid Sampling
A Hadassah University Medical Center study, which demonstrated the benefits of using a novel needle for spinal fluid sampling, was highlighted in the December 2011 issue of the British Journal of Anesthesia.
The article, authored by Dr. Yehuda Ginosar of the Department of Anesthesiology and Critical Care Medicine and Prof. Tamir Ben-Hur, head of Hadassah's Department of Neurology, along with Dr. Yoav Smith of the Genomic Data Analysis Unit at the Hadassah-Hebrew University Medical School, and American Student Jordana Lovett, supports the use of a 22 G spinal needle with a tapered 27 G pencil-point tip for spinal fluid extraction. Traditionally, the authors note, "parallel-walled spinal needles ≤22 G are used for lumbar punctures, despite a reported greater than 32 percent incidence of post-dural puncture headache." The researchers had hypothesized that despite the smaller puncture hole with their tapered spinal needle, the needle would have similar cerebrospinal fluid pressure equilibration times. The researchers concluded that "a 22/27 G tapered spinal needle has similar flow properties to the 22 G needle, despite a 27 G tip."
Hadasit, Hadassah’s Technology Transfer Arm, Reviews
When the Hadassah University Medical Center’s physicians suggest a
solution to a medical problem which can lead to the development of a new
medicine or product, Hadasit, Hadassah’s technology transfer arm, explores its
feasibility and supports the promotion of those viable ideas with innovation
potential. Although 2012 has been “a year full of challenges for the life
science industry,” says Einat Zisman, Hadasit’s Chief Executive Officer,
Hadasit still signed 125 agreements for clinical trials, all to be done at
Hadassah. In addition, Hadasit signed 15 agreements for cooperation and
commercialization of technologies that were developed at Hadassah. Click here
