Zummer J, et al. - This study seeks to ascertain ultrasound performed by emergency physicians enhances the probability of first-attempt success for lumbar puncture in children. A prospective randomized controlled trial was conducted in two tertiary care, pediatric, university-affiliated emergency departments between 2017–2018. Individuals were assigned randomly to either the standard landmark-based LP (SLP) or ultrasound-assisted LP (UALP) groups. The primary endpoint included the first-attempt LP success rate. Researchers included a total of 166 individuals, with 84 in the UALP and 82 in the SLP group. A sum of 23 physicians conducted ultrasounds in the study. In children, the study does not guide the routine use of ultrasound for conducting lumbar puncture. The results revealed that ultrasound may be applied as an adjunct and teaching tool in certain clinical situations considering the minimal harm and ease of performance.
