BackgroundFebrile infants frequently present to the emergency department (ED) and account for a vulnerable population at significant risk for serious bacterial infection. Appropriate evaluation and management are key to favorable outcomes but can present challenges for providers, especially in EDs where ill children are infrequently seen and pediatric-trained staff may not be available. Point-of-care ultrasound (POCUS) is integrated into the care of adults in the ED but is less commonly used for infants.Objective Of ReviewWe present a review of the current literature and proposed approach to using POCUS for bladder catheterization, lumbar puncture (LP), and vascular access in the resuscitation and evaluation of febrile infants.DiscussionPoint-of-care ultrasound can be a useful adjunct in the evaluation of febrile infants by facilitating higher success rates of infant bladder catheterization, LP, and intraosseous and intravenous (IV) line placement. Ultrasound has been shown to be a reliable method of evaluating bladder volumes before the catheterization of infants, reducing the number of attempts needed to obtain an adequate urine sample for testing and culture. Point-of-care ultrasound has also been shown to improve the yield of LPs in infants. Ultrasound is a rapid and accurate way of identifying the appropriate location and depth of needle insertion. Point-of-care ultrasound has also been shown to facilitate obtaining IV access in infants as well as confirming the proper placement of intraosseous lines.ConclusionsA growing body of evidence suggests that POCUS is a useful adjunct in the initial evaluation and resuscitation of febrile infants. It is the position of both the American Academy or Pediatrics, American College of Emergency Physicians, and the authors of this article that emergency physicians should be familiar with the indications and applications of POCUS in children. This technology should be used as an adjunct to improve success rates when performing bladder catheterization, LP, and obtaining intravenous/intraosseous access for infants.Copyright © 2021 Wolters Kluwer Health, Inc.
