Ultrasound Guided Diagnostic Lumbar Puncture in Neurology

Seventy‐two subjects will be randomized into either a traditional landmark‐based lumbar puncture or an ultrasound‐guided lumbar puncture for obtaining CSF. This study will be conducted in the Neurology clinic. For subjects in the traditional group, the site of needle entry will be determined through palpation of the spine. For subjects in the ultrasound group, site entry will be done using ultrasound guidance. Success and failure of these techniques will be compared along with secondary outcome measures aimed at assessing the safety and efficacy of each of these techniques.
