Few studies evaluate the use of handheld ultrasound devices for point-of-care ultrasonography in the emergency department. We hypothesized that image acquisition time and image quality are similar between a handheld device and a traditional device. We compared these 2 types of devices in healthy, non-pregnant adults with using a crossover non-inferiority design while acquiring Rapid Ultrasound for Shock and Hypotension (RUSH) view. We excluded those with a history of surgical intervention or known abnormality to the lungs, abdomen, or pelvis. Images were compiled into a de-identified video clip reviewed for image quality by 2 blinded reviewers. Cohen's Kappa was used to determine interrater agreement. Disagreements were adjudicated by an independent physician. Imaging time was compared using a paired Student's t test. Of 59 screened participants, 9 were excluded. Most subjects (N = 30, 60%) were female with a mean age of 39 (Range: 19-67) years. The median time to complete the RUSH exam did not differ (handheld 249.4, interquartile range 33.5 seconds); traditional 251.4, interquartile range 66.3 seconds); [P = 0.81]). Agreement between ultrasound reviewers was good (agreement 83%; k = 0.69; 95% CI, 0.49-0.88). Images were determined to be of adequate quality for interpretation in 41/50 (82%) and 43/50 (86%) in the handheld and traditional devices, respectively (P = 0.786). Neither time to image acquisition nor image quality differed between the handheld and traditional devices. The handheld device may be an alternative for use in RUSH exams.

A patient with a history of multiple jejunal diverticulosis (JD) presented with a non-peritonitic abdominal pain and leucocytosis. CT scan showed a thick-walled interloop collection within the left mid-abdomen with dilated bowels and mild diffuse air-fluid levels. Exploratory laparotomy revealed multiple diverticular outpouchings in the mid-jejunum, one of which was perforated, contained within the mesentery. Resection of the contained abscess and primary anastomosis were performed subsequently.

Background Simulated needle thoracostomy (NT) using ultrasound may reduce potential injury, increase accuracy, and be as rapid to perform as the traditional landmark technique following a brief educational session. Our objective was to determine if the use of an educational session demonstrating the use of handheld ultrasound to Emergency Medical Services (EMS) staff to facilitate NT was both feasible, and an effective way of increasing the safety and efficacy of this procedure for rural EMS providers. Methods A pre/post-educational intervention on a convenience sample of rural North American EMS paramedics and nurses. Measurement of location and estimated depth of placement of needle thoracostomy with traditional landmark technique was completed and then repeated using handheld ultrasound following a training session on thoracic ultrasound and correct placement of NT. Results A total of 30 EMS practitioners participated. Seven were female (23.3%). There was a higher frequency of dangerous structures underlying the chosen location with the landmark technique 9/60 (15%) compared to the ultrasound technique 1/60 (1.7%) (p = 0.08). Mean time-to-site-selection for the landmark technique was shorter than the ultrasound technique at 10.7 s (range 3.35–45 s) vs. 19.9 s (range 7.8–50 s), respectively (p < 0.001). There was a lower proportion of correct location selection for the landmark technique 40/60 (66.7%) when compared to the ultrasound technique 51/60 (85%) (p = 0.019). With ultrasound, there was less variance between the estimated and measured depth of the pleural space with a mean difference of 0.033 cm (range 0–0.5 cm) when ultrasound was used as compared to a mean difference of 1.0375 cm (range 0–6 cm) for the landmark technique (95% CI for the difference 0.73–1.27 cm; p < 0.001). Conclusions Teaching ultrasound NT was feasible in our cohort. While time-to-site-selection for ultrasound-guided NT took longer than the landmark technique, it increased safe and accurate simulated NT placement with fewer identified potential iatrogenic injuries.

The use of household cleaners during non‐commercial cleaning applications is a very common task, and the chemical makeup of the cleaning solutions vary as much as their applications do. Although most users of these products follow the written safety directions and are generally careful with their use, it is not uncommon for users to suffer toxicologic effects of these cleaners without proper protective equipment. In this case report, we describe an unusual chemical burn pattern to the hand of a young female patient after prolonged exposure to a xylene‐containing product without proper chemical‐resistant gloves. Fortunately, with prompt recognition, and urgent referral for burn treatment, the patient underwent a successful debridement of the burn and suffered minimal functional impairment.
