RESUMEN
INTRODUCTION: Emergency medicine point-of-care ultrasonography (EM-PoCUS) is a core competency for residents in the Royal College of Physicians and Surgeons of Canada and College of Family Physicians of Canada emergency medicine (EM) training programs. Although EM-PoCUS fellowships are currently offered in Canada, there is little consensus regarding what training should be included in a Canadian EM-PoCUS fellowship curriculum or how this contrasts with the training received in an EM residency.Objectives To conduct a systematic needs assessment of major stakeholders to define the essential elements necessary for a Canadian EM-PoCUS fellowship training curriculum. METHODS: We carried out a national survey of experts in EM-PoCUS, EM residency program directors, and EM residents. Respondents were asked to identify competencies deemed either nonessential to EM practice, essential for general EM practice, essential for advanced EM practice, or essential for EM-PoCUS fellowship trained (''expert'') practice. RESULTS: The response rate was 81% (351 of 435). PoCUS was deemed essential to general EM practice for basic cardiac, aortic, trauma, and procedural imaging. PoCUS was deemed essential to advanced EM practice in undifferentiated symptomatology, advanced chest pathologies, and advanced procedural applications. Expert-level PoCUS competencies were identified for administrative, pediatric, and advanced gynecologic applications. Eighty-seven percent of respondents indicated that there was a need for EM-PoCUS fellowships, with an ideal length of 6 months. CONCLUSION: This is the first needs assessment of major stakeholders in Canada to identify competencies for expert training in EM-PoCUS. The competencies should form the basis for EM-PoCUS fellowship programs in Canada.

INTRODUCTION: Ultrasound guidance for central line placement in the subclavian vein (SCV) is more efficient and safer than landmark-based technique. The supraclavicular (SC) approach is an alternative to the infraclavicular (IC) approach, but the research is sparse. The objective was to determine which approach provides the best view. METHODS: This was a prospective anatomical survey of voluntary normovolemic patients. Four experienced emergency physicians and 1 resident scanned the right and left SCVs from SC and IC approaches. They assigned a score for the views obtained on a 5-point Likert scale. RESULTS: Ninety-eight patients were enrolled. Mean Likert scores for the 4 views were: right SC, 4.06 (95% confidence interval [CI], 0.22); right IC, 3.07 (95% CI, 0.25); left SC, 3.82 (95% CI, 0.23); left IC, 3.12 (95% CI, 0.25). When combining data from right and left, the mean score for the SC view was significantly higher than the mean score for the IC view: 3.94 (95% CI, 0.16) vs 3.10 (95% CI, 0.18). The following ratings were obtained: right SC view was good or excellent in 71.5%; left SC view was good or excellent in 66.3%; right IC view was good or excellent in 37.8%; and left IC view was good or excellent in 38.8%. CONCLUSION: The SC approach allows for a better view of the SCV on ultrasound than the IC approach. Future research should determine if this translates to a greater success rate when placing central lines in the SCV.

OBJECTIVE: Determination of jugular venous pressure (JVP) by physical examination (E-JVP) is unreliable. Measurement of JVP with ultrasonography (U-JVP) is easy to perform, but the normal range is unknown. The objective of this study was to determine the normal range for U-JVP. METHODS: We conducted a prospective anatomic study on a convenience sample of emergency department (ED) patients over 35 years of age. We excluded patients who had findings on history or physical examination suggesting an alteration of JVP. With the head of the bed at 45 degrees, we determined the point at which the diameter of the internal jugular vein (IJV) began to decrease on ultrasonography ("the taper"). Research assistants used 2 techniques to measure U-JVP in all participants: by measuring the vertical height (in centimetres) of the taper above the sternal angle, and adding 5 cm; and by recording the quadrant in the IJV's path from the clavicle to the angle of the jaw in which the taper was located. To determine interrater reliability, separate examiners measured the U-JVP of 15 participants. RESULTS: We successfully determined the U-JVP of all 77 participants (38 male and 39 female). The mean U-JVP was 6.35 (95% confidence interval 6.11-6.59) cm. In 76 participants (98.7%), the taper was located in the first quadrant. Determination of interrater reliability found kappa values of 1.00 and 0.87 for techniques 1 and 2, respectively. CONCLUSION: The normal U-JVP is 6.35 cm, a value that is slightly lower than the published normal E-JVP. Interrater reliability for U-JVP is excellent. The top of the IJV column is located less than 25% of the distance from the clavicle to the angle of the jaw in the majority of healthy adults. Our findings suggest that U-JVP provides the potential to reincorporate reliable JVP measurement into clinical assessment in the ED. However, further research in this area is warranted.
