Point-of-Care Ultrasound for Central Venous Assessment in the Emergency Department: A Prospective Study Comparing the Femoral and Internal Jugular Veins.

OBJECTIVES: The objective of this study was to estimate the width, height, and depth of the femoral vein (FV) and internal jugular vein (IJV), both sites of potential central line placement in children, using point-of-care ultrasound. METHODS: This was a prospective observational study. Point-of-care ultrasound was used to measure the width, height, and depth of the right FV and IJV in 100 children. The primary outcome was a comparison of the widths of the FV and the IJV in the same child. Our primary hypothesis was that the IJV would be wider than the FV. Secondary outcome measures included comparison of the heights and depths the FV and IJV and description of vessel overlap frequency between the 2 sites. RESULTS: A total of 106 children were enrolled, with 6 subjects excluded, and equally divided into 5 age groups (0-30 days, 1-24 months, 2-5 years, 6-11 years, and 12-17 years). The FV/IJV width ratios (95% confidence interval) by age were 0.58 (0.49-0.68), 0.53 (0.43-0.66), 0.57 (0.49-0.67), 0.68 (0.55-0.85), and 0.73 (0.62-0.85), all P < 0.002. The FV/IJV height ratios were <1 in all age groups, with P < 0.003 in the 4 youngest age groups. The FV/IJV depth ratios were >1 in 6 to 11 years (P = 0.018) and 12 to 17 years (P < 0.001). CONCLUSIONS: The IJV was significantly wider and taller than the FV in the same child in all age groups. The FV was significantly deeper than the IJV in children 6 years and older. This supports the use of the IJV as a potential site when placing ultrasound-guided central lines in children.

Pediatric Outcomes of Emergency Medical Services Non-Transport Before and During the COVID-19 Pandemic.

Introduction: Pediatric patients account for 6-10% of emergency medical services (EMS) activations in the United States. Approximately 30% of these children are not transported to an emergency department (ED). Adult data in the literature reports higher hospitalization and complications following non-transport. Few studies discuss epidemiology and characteristics of pediatric non-transport; however, data on outcome is limited. Our primary aim was to determine outcomes of non-transported children within our urban EMS system before and during the COVID-19 pandemic. Our secondary objective was to explore reasons for non-transport. Methods: This was a prospective, descriptive pilot study. We compared EMS data for September 2019 (pre-COVID-19) to September 2020 (pandemic). Included were children aged 0-17 years who activated EMS and did not receive transport to the primary hospital for the EMS capture area. We defined outcomes as repeat EMS activation, ED visits, and hospital admissions, all within 72 hours. Data was obtained via electronic capture. We used descriptive statistics to analyze our data, chi square for categorical data, stepwise logistic regression, and univariate logistic regression to test for association of covariates with non-transport. Results: There were 1,089 pediatric EMS activations in September 2019 and 780 in September 2020. Non-transport occurred in 633 (58%) in September 2019 and 412 (53%) in September 2020. Emergency medical services was reactivated within 72 hours in the following: 9/633 (1.4%) in 2019; and 5/412 (1.2%) in 2020 (P = 0.77). Visits to the ED occurred in 57/633 (9%) in 2019 and 42/412 (10%) in 2020 (P = 0.53). Hospital admissions occurred in 10/633 (1.5%) in 2019 and 4/412 (0.97%) in 2020 (P = 0.19). One non-transported patient was admitted to the intensive care unit in September 2020 (<1%) and survived. Hispanic ethnicity, age >12 years, and fever were associated with repeat EMS activation. The most common reason for non-transport in both study periods was that the parent felt an ambulance was not necessary (47%). Conclusion: In our system, non-transport of pediatric patients occurred in >50% of EMS activations with no significant adverse outcome. Age >12 years, fever, and Hispanic ethnicity were more common in repeated EMS activations. The most common reason for non-transport was parents feeling it was not necessary. Future studies are needed to develop reliable EMS guidelines for pediatric non-transport.

A novel medical apparatus for the containment and evaluation of a pediatric patient under suspicion for highly communicable infectious disease.

BACKGROUND: Highly communicable infectious diseases (HCIDs) such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Ebola are a containment challenge for the emergency department (ED). Donning and doffing personal protective equipment is necessary to protect healthcare workers but is time consuming and rife with errors. Furthermore, children present an additional containment challenge since they are often unable to follow directions or be separated from family members. To address these challenges, a novel child-friendly medical apparatus was developed for the rapid containment and evaluation of a HCID patient in the ED. OBJECTIVES: The primary objective was to determine if routine emergency triage procedures (vital signs and basic physical examination) can be performed using this medical apparatus. The secondary objective was to determine if invasive procedures (bag-valve-mask ventilation and endotracheal intubation) can be performed. DESIGN: This was a prospective pilot study. A clear acrylic apparatus was built containing arm ports with gloves, simulating a specialized HCID barrier. Emergency physicians attempted routine triage procedures on a healthy volunteer and invasive procedures using a simulation mannequin through this apparatus. RESULTS: Twenty-four physicians were enrolled. All physicians (100 percent) successfully obtained vital signs, auscultated heart/lung sounds, completed bag-valve-mask ventilation, and performed intubation through the apparatus. CONCLUSIONS: This novel apparatus is a feasible tool in the rapid evaluation of a HCID patient in the ED. A future study is needed to assess protection and training using this apparatus.
