Ultrasound Guided Diagnostic Lumbar Puncture in Neurology

Ultrasound Guided Diagnostic Lumbar Puncture in Neurology

Subjects who are having a lumbar puncture as part of their clinical care will be randomized to either a traditional landmark based lumbar puncture or ultrasound guided lumbar puncture. The primary objective of study is to compare the success rate of obtaining CSF using Ultrasound guided technique against the Traditional Landmark based approach. Secondary objectives are to evaluate factors influencing the success or failure, patient tolerance, and a safety assessment.

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.

Inclusion Criteria:

• Patient scheduled for LP through Neurology's LP clinic
• 18 years of age or older
• Able to understand the description of procedure and provide informed consent

Exclusion Criteria:

• Any contraindications to doing a standard lumbar puncture; which typically includes risk of bleeding from effects of anticoagulants or bleeding disorders or an infection at the potential site of entry in the back. This includes subjects with spinal cord stimulators.
