Poster Abstract
Ultrasound guidance for lumbar puncture (LP) is well established for pre-procedural landmark identification, particularly in patients with difficult anatomy. However, most current approaches discontinue ultrasound prior to needle insertion, returning the operator to a blind technique. Current emergency medicine ultrasound guided intravenous line insertion demonstrate feasibility of real-time needle visualization. However, the development and adoption of real-time guidance in the setting of lumbar puncture remains limited. Prior simulation work demonstrated that ergonomics, operator experience, and workflow integration significantly influence performance in ultrasound-assisted LP (Horn, Espinosa et al., 2016). Here we make the case that LP is not a static targeting problem but a dynamic trajectory problem. Intraprocedural ultrasound may offer its greatest value when integrated continuously into needle advancement rather than used solely for landmark localization. Recommendations are made for future research, including the development and testing of hands-free probe holders or needle-tracking technologies specific to LP.

The Case for Intraprocedural Ultrasound Guidance in Lumbar Puncture--From Landmarking to Navigation in Lumbar Puncture. A Conceptual Review and Research Agenda
