Importance: The wide variation in the accuracy and reliability of the Focused Assessment With Sonography for Trauma (FAST) and the extended FAST (E-FAST) for children after blunt abdominal trauma reflects user expertise. FAST and E-FAST that are performed by experts tend to be more complete, better quality, and more often clinically valuable.

Objective: To develop definitions of a complete, high-quality, and accurate interpretation for the FAST and E-FAST in children with injury using an expert, consensus-based modified Delphi technique.

Objectives: Using an education and assessment tool, we examined the number of cases necessary to achieve a performance benchmark in image interpretation of pediatric soft tissue, cardiac, lung, and focused assessment with sonography for trauma (FAST) point-of-care ultrasound (POCUS) applications. We also determined interpretation difficulty scores to derive which cases provided the greatest diagnostic challenges.

Methods: Pediatric emergency physicians participated in web-based pediatric POCUS courses sponsored by their institution as a credentialing priority.

Background: Intussusception is a common pediatric emergency. The two types of intussusception are ileocolic intussusception (ICI) and small bowel-small bowel intussusception (SB-SBI), and neither are easily distinguished clinically. ICI requires radiology personnel and potentially surgical assistance for its reduction.

Purpose: Point-of-care ultrasound (POCUS) is growing, but few data exist regarding its effects on radiology ultrasound (Rad US) volumes. The authors studied changes in Rad US ordered by emergency medicine (EM) as POCUS began and grew at their pediatric hospital.

Methods: This retrospective study included EM POCUS and EM-ordered Rad US volumes between 2011 and 2017, during three 2-year intervals: before POCUS, early POCUS, and expanded POCUS.

Background: We sought to determine if vertebral interspace selection for performance of infant lumbar puncture (LP) varies between less experienced trainees and more experienced pediatric emergency medicine (PEM) attending physicians.

Methods: We performed an observational prospective study using a convenience sample of infants aged 0 to 12 months presenting to a single emergency department. Trainees with limited LP experience (defined as less than 10 infant LPs performed) marked their preferred LP insertion site with an invisible ultraviolet pen.

Objective: Traditionally, patient-reported fasting time has been the primary objective presedation measure of aspiration risk. Recently, gastric ultrasound has been used to assess gastric volume for the determination of aspiration risk in patients undergoing anesthesia in the operative setting. We sought to determine the correlation of gastric volume estimated by point-of-care ultrasound (POCUS) to reported fasting time.

Point-of-care ultrasound is currently widely used across the landscape of pediatric care. Ultrasound machines are now smaller, are easier to use, and have much improved image quality. They have become common in emergency departments, ICUs, inpatient wards, and outpatient clinics.

As point-of-care ultrasound (POCUS) becomes standard practice in pediatric emergency medicine (PEM), it is important to have benchmarks in place for credentialing PEM faculty in POCUS. Faculty must be systematically trained and assessed for competency in order to be credentialed in POCUS and granted privileges by an individual institution. Recommendations on credentialing PEM faculty are needed to ensure appropriate, consistent, and responsible use of this diagnostic and procedural tool.

Hydrocephalus carries significant morbidity in the infant population. Although clinical symptoms are often nonspecific, hydrocephalus is easily identified using transfontanellar sonography. In this review, we provide the emergency physician with a succinct overview of infant hydrocephalus and the point-of-care ultrasound (POCUS) technique for identification of this pathology.

Objectives: Point-of-care ultrasound (POCUS) may facilitate the diagnosis and management of children for various conditions. Integration of POCUS into clinical care requires hands-on training; however, providers may be reluctant to perform educational ultrasounds to improve their skills, as it is a procedure without direct clinical benefit to the patient and due to concerns that it may lower a family's overall satisfaction. We sought to evaluate whether the use of POCUS changed overall patient/caregiver satisfaction in a pediatric emergency department (ED) visit.

Objective: We sought to determine which interventions have effectively increased point-of-care ultrasound (US) use in a pediatric emergency department (ED).

Design/methods: We evaluated the impact of specific interventions conducted over a 5-year period (2010-2015) on point-of-care US performance in a tertiary care pediatric ED. Ultrasound use by attending physicians and fellows was ascertained from a departmental database.

Background: Point-of-care ultrasound (POCUS) is increasingly being used to differentiate cellulitis from abscess in the pediatric emergency department (ED). POCUS has also been shown to decrease length of stay (LOS) for other applications among adult patients.

Objective: We sought to determine if ED LOS differed for children presenting with skin and soft tissue infections who received POCUS versus radiology-performed ultrasound.

We report a case of a patient presenting with abdominal pain after cardiac surgery who was noted on point-of-care ultrasound (POCUS) to have pericardial and pleural effusion, in addition to ascites. The most notable findings were pleural and pericardial effusions, which combined with symptomatology met criteria for postpericardiotomy syndrome. Point-of-care ultrasound expedited the diagnosis of a pericardial effusion with impending tamponade and transfer for pericardiocentesis and placement of pericardial drain.

Objective: To determine the location of intraperitoneal free fluid on FAST exam in pediatric patients undergoing evaluation for trauma.

Methods: Retrospective review of all FAST exams positive for intraperitoneal free fluid performed in patients sustaining trauma between August 2009 and February 2016 in an urban pediatric emergency department. Positive results were categorized into one of nine potential intraperitoneal locations; 4 each in the right and left upper quadrants, and the pelvis.

The utility of point-of-care ultrasound is well supported by the medical literature. Consequently, pediatric emergency medicine providers have embraced this technology in everyday practice. Recently, the American Academy of Pediatrics published a policy statement endorsing the use of point-of-care ultrasound by pediatric emergency medicine providers.

Objective: Ultrasound (US) guidance for central venous catheter (CVC) placement results in improved success and overall safety, but is a new skill for pediatric emergency medicine (PEM) physicians. No study to date has used simulation-based learning to evaluate the ability of PEM providers to perform US-guided CVC placement.Our objective was to assess the competency of physicians in a rarely performed procedure, US-guided CVC placement, before and after an educational intervention using simulation-based mastery learning.
