International Scope of Emergency Ultrasound: Barriers in Applying Ultrasound to Guide Central Line Placement by Providers in Nairobi, Kenya

Background While ultrasound (US) use for internal jugular central venous catheter (CVC) placement is standard of care in North America, most developing countries have not adopted this practice. Previous surveys of North American physicians have identified lack of training and equipment availability as the most important barriers to the use of US. Go to: Objective We sought to identify perceived barriers to the use of US to guide CVC insertion in a resource-constrained environment. Go to: Methods Prior to an US-guided CVC placement training course conducted at the Aga Khan University Hospital in Nairobi, Kenya, physicians were asked to complete a survey to determine previous experience and perceived barriers. Survey responses were analyzed using summary statistics and the Rank-Sum test based on different specialty, gender, and previous US experience. Go to: Results There were 23 physicians who completed the course and the survey. 52% (95% CI: 0.30–0.73) had put in \u3e20 CVCs. 21.7% (95% CI: 0.08–0.44) of participants had previous US training, but none in the use of US for CVC insertion. The respondents expressed agreement with statements describing the ease of the use and improved success rate with US guidance. There was less agreement to statements describing the relative convenience and cost effectiveness of US CVC placement compared to the landmark technique. The main perceived barriers to utilization of US guidance included lack of training and limited availability of US equipment and sterile sheaths. Go to: Conclusion Perceived barriers to US-guided CVC placement in our population closely mirrored those found among North American physicians, including lack of training and limited availability of US machines and equipment. These barriers have the potential to be addressed by targeted educational and administrative interventions

An Echocardiography Training Program for Improving the Left Ventricular Function Interpretation in Emergency Department; a Brief Report

Introduction: Focused training in transthoracic echocardiography enables emergency physicians (EPs) to accurately estimate the left ventricular function. This study aimed to evaluate the efficacy of a brief training program utilizing standardized echocardiography video clips in this regard. Methods: A before and after design was used to determine the efficacy of a 1 hour echocardiography training program using PowerPoint presentation and standardized echocardiography video clips illustrating normal and abnormal left ventricular ejection fraction (LVEF) as well as video clips emphasizing the measurement of mitral valve E-point septal separation (EPSS). Pre- and post-test evaluation used unique video clips and asked trainees to estimate LVEF and EPSS based on the viewed video clips. Results: 21 EPs with no prior experience with the echocardiographic technical methods completed this study. The EPs had very limited prior echocardiographic training. The mean score on the categorization of LVEF estimation improved from 4.9 (95% CI: 4.1-5.6) to 7.6 (95%CI: 7-8.3) out of a possible 10 score (

A cruise ship emergency medical evacuation triggered by handheld ultrasound findings and directed by tele-ultrasound

Cruise ships travel far from shoreside medical care and present a unique austere medical environment. For the cruise ship physician, decisions regarding emergency medical evacuation can be challenging. In the event that a passenger or crew member becomes seriously ill or is injured, the use of point-of-care ultrasound may assist in clarifying the diagnosis and stratifying the risk of a delayed care, and at times expedite an emergent medical evacuation. In this report we present the first case reported in the literaturę of an emergency medical evacuation from a cruise ship triggered by handheld ultrasound. A point-of-care ultrasound performed by a trained cruise ship physician, reviewed by a remote telemedical consultant with experience in point-of-care ultrasound, identified an ectopic pregnancy with intraabdominal free fluid in a young female patient with abdominal pain and expedited emergent helicopter evacuation from a cruise ship to a shoreside facility, where she immediately underwent successful surgery. The case highlights a medical evacuation that was accurately triggered by utilising a handheld ultrasound and successfully directed via a tele-ultrasound consultation. American College of Emergency Physicians (ACEP) health care guidelines for cruise ship medical facilities should be updated to include guidelines for point-of-care ultrasound, including training and telemedical support

Ultrasound and Perforated Viscus; Dirty Fluid, Dirty Shadows, and Peritoneal Enhancement.

Early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. We present a series of cases in which bedside ultrasound (US) in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty) free fluid consistent with a surgical final diagnosis of a perforated hollow viscus. In all patients with suspected perforated viscus, clinicians were able to accurately identify the signs of pneumoperitoneum including enhanced peritoneal stripe sign (EPSS), peritoneal stripe reverberations, and focal air collections associated with dirty shadowing or distal multiple reflections as ring down artifacts. In all cases, hollow viscus perforation was confirmed surgically. It seems that, performing US in patients with suspected perforated viscus can accurately identify presence of intra-peritoneal echogenic or dirty free fluid as well as evidence of free air, and may expedite patient management
