Kessler D, et al. - The potential effect of preprocedural ultrasound (US) to increase lumbar puncture (LP) success compared with standard palpation method was investigated. In addition, researchers ascertained feasibility of and clinician satisfaction with a standardized US protocol. In this prospective, two-arm, parallel-group randomized trial, infants less than 3 months of age requiring LP were enrolled. Training was provided to 16 pediatric emergency medicine physicians, with varied US experience, to conduct the USs to mark interspace locations. No improvement in the rates of first-attempt success was noted with the preprocedural US when compared with palpation method. As per findings, US is feasible and well accepted, with a perceptible impact on care.
