Who performs lumbar puncture?

Physicians who perform diagnostic lumbar punctures typically include emergency department physicians, anesthesiologists, and neurologists. The anesthesiologist also performs spinal anesthesia and other procedures, including lumbar punctures. Radiologists and neuroradiologists perform lumbar punctures under the guidance of imaging to perform diagnostic imaging, such as myelography, and other procedures. Doctors who do these things more often often employ a technique that reduces the incidence of post-dural headaches.

The size of the needle used for lumbar puncture is an obvious factor affecting the risk of PDPH or persistent dural foramen leakage. Needles come in various sizes and are measured according to specifications. The lower the specification number, the larger the needle. For cerebrospinal fluid sampling, a smaller needle is sufficient. For contrast media injection, the specific requirements of the procedure affect the adequacy of the needle gauge and type detailed below.
