Point-of-Care Ultrasound for Intubation Confirmation of COVID-19 Patients

The novel coronavirus disease of 2019 (COVID-19) is associated with significant morbidity and mortality, as well as large numbers of patients requiring endotracheal intubation. While much of the literature has focused on the intubation technique, there is scant discussion of intubation confirmation. Herein, we discuss the limitations of traditional confirmatory approaches, summarize the literature supporting a role for point-of-care ultrasound in this application, and propose an algorithm for intubation confirmation among COVID-19 patients

Incorporation of Transcranial Doppler into the ED for the neurocritical care patient

Introduction: In the catastrophic neurologic emergency, a complete neurological exam is not always possible or feasible given the time-sensitive nature of the underlying disease process, or if emergent airway management is indicated. As the neurologic exam may be limited in some patients, the emergency physician is reliant on the assessment of brainstem structures to determine neurological function. Physicians thus routinely depend on advanced imaging modalities to further investigate for potential catastrophic diagnoses. Acquiring these tests introduces the risks of transport as well as delays in managing time-sensitive neurologic processes. A more immediate, non-invasive bedside approach complementing these modalities has evolved: Transcranial Doppler (TCD). Objective: This narrative review will provide a description of scenarios in which TCD may be applicable. It will summarize the sonographic findings and associated underlying pathophysiology in such neurocritical care patients. An illustrated tutorial, along with pearls and pitfalls, is provided. Discussion: Although there are numerous formalized TCD protocols utilizing four views (transtemporal, submandibular, suboccipital, and transorbital), point-of-care TCD is best accomplished through the transtemporal window. The core applications include the evaluation of midline shift, vasospasm after subarachnoid hemorrhage, acute ischemic stroke, and elevated intracranial pressure. An illustrative tutorial is provided. Conclusions: With the wide dissemination of bedside ultrasound within the emergency department, there is a unique opportunity for the emergency physician to utilize TCD fora variety of conditions. While barriers to training exist, emergency physician performance of limited point-of-care TCD is feasible and may provide rapid and reliable clinical information with high temporal resolution.

National Survey of Point-of-Care Ultrasound Scholarly Tracks in Emergency Medicine Residency Programs

Introduction: Residency scholarly tracks are educational programs, designed to help trainees develop an area of expertise. Although the breadth of residency point-of-care ultrasound (POCUS) education has developed considerably in recent years, there is no literature to date describing scholarly tracks specifically in POCUS. In this study we sought to determine the prevalence, characteristics, and outcomes of POCUS scholarly tracks in emergency medicine (EM). Methods: This was a cross-sectional survey of EM residency programs accredited by the Accreditation Council for Graduate Medical Education. Surveys were distributed between March-August 2020 using a listserv followed by targeted emails to residency and ultrasound leadership. We summarized data using descriptive statistics, and performed logistic regression to identify factors associated with a POCUS scholarly track. Results: Of 267 residency programs 199 (74.5%) completed the survey. Fifty-seven (28.6%) had a POCUS scholarly track as of the 2019-2020 academic year. Scholarly tracks in POCUS were more common in university-based/academic sites and larger residency programs. Of the 57 programs with POCUS scholarly tracks, 48 (84.2%) required residents to present at least one POCUS lecture, 45 (78.9%) required residents to serve as instructor at a hands-on workshop, and 42 (73.7%) required residents to participate in quality assurance of departmental POCUS scans. Only 28 (49.1%) tracks had a structured curriculum, and 26 (45.6%) required POCUS research. In total, 300 EM residents completed a POCUS scholarly track over the past three academic years, with a median of 4 (2-9) per program. Seventy-five (25.0%) proceeded to a clinical ultrasound fellowship after residency graduation, with a median of 1 (interquartile range 0-2) per program. A total of 139 POCUS-specific abstracts (median 2 [0-3]) and 80 peer-reviewed manuscripts (median 1 [0-2]) were published by scholarly track residents over the past three years. Conclusion: This survey study describes the current prevalence, characteristics, and outcomes of POCUS scholarly tracks across EM residency programs. The results may inform the decisions of residency programs to create these tracks

Point-of-care echocardiography for the evaluation of right-to-left cardiopulmonary shunts: a narrative review

Right-to-left pulmonary and cardiac shunts (RLS) are important causes of refractory hypoxia in the critically-ill perioperative patient. Using a point-of-care ultrasound (POCUS) agitated saline bubble study for an early diagnosis allows patients with clinically significant RLSs to receive expedited therapy. This narrative review discusses the principles of agitated saline ultrasonography as well as the role of POCUS in detecting the most common RLS types seen in the intensive care unit, including patent foramen ovale, atrial septal defects, and pulmonary arterio-venous malformations. An illustrated discussion of the procedure, as well as shunt-enhancing maneuvers (Valsalva or lung recruitment maneuver with subsequent rapid release) is provided. With the wide dissemination of bedside ultrasound within the perioperative and critical care arena, POCUS practitioners should be knowledgeable of the potential pitfalls leading to both false-positive and false-negative studies. False-positive studies may be due to congenital abnormalities, mischaracterization of intrapulmonary shunts as intracardiac shunts (and vice versa), or evidence of the Valsalva effect. False negatives are typically due to respiratory-phasic variation, performing an inadequate shunt-enhancing maneuver, inadequate injection of agitated saline, or pathophysiologic states of elevated left atrial pressure. Finally, alternative POCUS methods for determining presence of an RLS in patients with poor echocardiographic windows are discussed, with a focus on pulsed-wave Doppler interrogation of arterial signals
