The P2Network-Advancing Pediatric Emergency Care With Point-of-Care Ultrasound.

ABSTRACT: Over the last 2 decades, the use of point-of-care ultrasound (POCUS) in pediatric emergency medicine (PEM) has grown exponentially. In 2014, a group of PEM POCUS leaders met and formed the P2Network. The P2Network provides a platform to build collaborative relationships and share expertise among members from various countries and practice settings. It works with educators and researchers within and outside of the field to advance POCUS practice in PEM. As an organization, the P2Network promotes the evidence-based application of POCUS to facilitate and improve care in the PEM setting and addresses issues related to integration of the PEM POCUS practitioner in this nascent field. The P2Network is building and augmenting its infrastructure for PEM POCUS research and education and has already made some progress in the areas, with published manuscripts and ongoing clinical research studies under its sponsorship. Future goals include developing a PEM POCUS research agenda, formalizing teaching and assessment of PEM POCUS skills, and implementing multicenter research studies on potentially high impact applications.

Point-of-Care Ultrasound for Pediatric Endotracheal Tube Placement Confirmation by Advanced Practice Transport Nurses.

OBJECTIVE: This study aimed to identify which point-of-care ultrasound (POCUS) techniques and sonographic signs were reliably acquired and interpreted by transport nurses for the confirmation of endotracheal tube placement in children. METHODS: We developed and assessed a multimodal POCUS training curriculum for transport nurses that evaluated 5 sonographic signs using 3 scanning techniques. RESULTS: Twenty-one transport nurses were enrolled in the curriculum. The mean scores (95% confidence interval [CI]) of the knowledge test were 82% (95% CI, 63%-93%), 88% (95% CI, 68%-95%), and 74% (95% CI, 53%-87%) for tracheal, lung, and hemidiaphragmatic scans, respectively. For the simulation image evaluation, 94% (95% CI, 77%-99%) of tracheal scan images, 97% (95% CI, 81%-99%) of lung scan images, and 88% (95% CI, 69%-96%) of hemidiaphragmatic scan images were determined clinically useful. For the pediatric intensive care unit image evaluation, 100% (95% CI, 86%-100%) of tracheal scan images, 100% (95% CI, 86%-100%) of lung scan images, and 79% (95% CI, 59%-91%) of hemidiaphragmatic scan images were determined clinically useful. A tracheal dilation sign was rarely captured by POCUS. CONCLUSION: Transport nurses can acquire POCUS skills to confirm endotracheal tube placement in children. A combination of a double trachea sign, a lung sliding sign, and a lung pulse sign could be a feasible POCUS approach.

Pediatric Concussion Management in the Emergency Department: A National Survey of Parents.

OBJECTIVE: To examine parental expectations and beliefs about diagnosis and management of pediatric concussion. STUDY DESIGN: We conducted a cross-sectional web-based survey of a nationally representative panel of US parents in March 2014. Parents of 10- to 17-year-old children responded to questions about their expectations and beliefs about diagnosis and management of pediatric concussion in the emergency department (ED). Weighted percentages for descriptive statistics were calculated, and χ2 statistics were used for bivariate analysis. RESULTS: Survey participation was 53%, and of 912 parent respondents with a child 10-17 years of age who were presented with a scenario of their child having mild symptoms of concussion, 42% would seek immediate ED care. Parents who would seek immediate ED care for this scenario were more likely than parents who would consult their child's usual provider or wait at home to "definitely expect" imaging (65% vs 21%), definitive diagnosis of concussion (77% vs 61%), a timeline for return to activity (80% vs 60%), and a signed return to play form (55% vs 41%). CONCLUSIONS: Many parents who bring children to the ED following a possible concussion are likely to expect comprehensive and definitive care, including imaging, a definitive diagnosis, a timeline for return to activity, and a signed return to play form. To manage these expectations, healthcare providers should continue to educate parents about the evaluation and management of concussion.

Acute vitamin D intoxication in a child.

We present the unique case of a previously healthy, 2-year-old boy with resistant hypercalcemia and hypertension resulting from an unintentional overdose with an imported vitamin D supplement. The patient presented initially to the emergency department with colic and constipation and was discharged after a benign physical examination. The symptoms persisted and, on the second visit, the patient was found to have a serum calcium level of 14.4 mg/dL. Despite therapy with intravenously administered 5% dextrose solution at one-half normal strength, furosemide, calcitonin, and hydrocortisone, the calcium concentration increased to 15.0 mg/dL on the second hospital day and did not decrease until the fourth hospital day, when it fell to 13.9 mg/dL. The vitamin D concentration peaked at 470 ng/mL on hospital day 3. With additional questioning, the mother revealed that she had been giving her son a daily dose of 1 ampule of Raquiferol, an imported vitamin D supplement, instead of the recommended 2 drops per day. Each ampule contained 600,000 IU of vitamin D; therefore, the boy received a total of 2,400,000 IU over 4 days. The patient's hypercalcemia persisted for 14 days and was complicated by persistent hypertension. No renal, cardiac, or neurologic complications were noted. At discharge, the vitamin D concentration was still elevated at 389 ng/mL and the total calcium level had decreased to 11 mg/dL. The boy made a complete clinical recovery. This case highlights the need for caution when using imported and/or unregulated medicines, as well as the dangers of parental dosing errors.
