Comparaison du repérage anatomique traditionnel et du repérage échographique du site de ponction lombaire

Abstract : Introduction: Anatomical landmarks used to determine intervertebral space for lumbar puncture are false in 30% of the cases. Ultrasound guidance is a suitable tool for learning and routine practice. We evaluated the difference between classical anatomical landmarks (CAL) and ultrasound location puncture (ULP). Methods: This observational monocentric prospective study was settled in the Emergency Department of the Universitary hospital of Grenoble. The main judgement criteria was the mean distance in millimeters between the punction site choosen by CAL and by ULP method. The patients with a potential indication of lumbar punction were included between 02/02/2016 and 03/04/2016. Mean distance difference was reported with confidence interval of 95% after verification of normal statistical distribution. Results: ULP was different from CAL with a mean distance difference of 32mm, CI95% (27 – 37). The mean vertical distance was 29 mm, CI95% (24 – 34). The mean horizontal difference was 8mm, CI95 % (6 – 10). The rate of change of intervertebral landmarks was 63%. Summary: ULP is different from CAL. The distance between these two methods is at least equal to one intervertebral space. There is a vertical and horizontal variation between ULP and CAL. These results could explain at least partially the low rate of failure of lumbar punction when realized by ULP method.
