An Original Mini Automated Ultrasound-based System for Spine Anesthesia Against Usual Sonography: Initial Case-serie
Background and Goal of Research study: Blinded spine anaesthesia (SA) remains a gold standard. A preliminary ultrasound (US) scan may improve security and efficacy1, however a few anaesthetists currently perform it (lack of understanding of spinal sonoanatomy1 utilizing poor US imaging low-frequency sonography2, S). A miniature automatic ultrasound-based system (MAUBS), as anatomical structure tracker, may be a solution for Dura mater (D) place during SA. The MAUBS (Accurou2122, Rivannau2122) principle is to identify initially the aspect joins in the US field, measure their depth and then, fuse (SpineNav3Du2122 technology) with a 3D spine anatomical model (Fig1) for real-time 3D lumbar navigation to assist in needle insertion.We report a preliminary case-series comparing MAUBS data against BW 2D S and depth measurement on the needle. Products and methods: Ten clients (orthopaedic surgery) were consisted of (2.5 ml HB bupi 0.5% Suf 5u00 b5g SA with 90 vs 150 mm long 25 G Witacre needle). The Fig. 1 displays the 4 steps approach concerning the multimodal D depth evaluation (steps 1-3) and verification on SA needle (step 4). Results and conversation: SA always prospered. The patientsu00 b4 data and results about method are noted in Table. The individualization of three distinct patterns (spinous procedure, vertebral laminae and facet joint with D) was constantly possible whatever the United States technology was. The Fig. 2 shows the particular private depth measurements concerning facet joint and D. Finally the intra-individual inter-measurement contrast validated the measuresu00 b4 similarity between the technologies. Conclusion: These definitive outcomes motivate the study of the MAUBS learning curve and its effect on SA practice. Referrals: 1. Br J Radiol 2012; 85: e262- e269 2. Med Ultrason 2014; 16: 356-63
