PURPOSE We hypothesized that novices would be able to use the McGrath MAC (Aircraft Medical Ltd, Edinburgh, UK) equally as well as the GlideScope Ranger (Verathon, Inc, Bothell, WA) for intubation in regular simulated airways. METHODS We performed a prospective, randomized crossover study of 39 medical students using the McGrath MAC, GlideScope Ranger,(More)
We examined the potential of the iPad 2 as a teleradiologic tool for evaluating brain computed tomography (CT) with subtle hemorrhage in the conventional lighting conditions which are common situations in the remote CT reading. The comparison of the clinician's performance was undertaken through detecting hemorrhage by the iPad 2 and the clinical liquid(More)
BACKGROUND We investigated which factors are associated with successful paediatric endotracheal intubation (ETI) on the first attempt in emergency department (EDs) from multicentre emergency airway registry data. METHODS We created a multicentre registry of intubations at 13 EDs and performed surveillance over 5 years. Each intubator filled out a data(More)
We developed a new type of mobile teleradiology system using an ultramobile PC (UMPC) for web-based remote viewing over a wireless network. We assessed the diagnostic performance of this system for abdominal CT interpretation. Performance was compared with an emergency department clinical monitor using a DICOM viewer. A total of 100 abdominal CT(More)
We aimed to evaluate the feasibility of an iPhone-based remote control system as a real-time remote computed tomography (CT) reading tool for suspected appendicitis using a third-generation (3G) network under suboptimal illumination. One hundred twenty abdominal CT scans were selected; 60 had no signs of appendicitis, whereas the remaining 60 had signs of(More)
PURPOSE We investigated the effectiveness of tele-mentored ultrasonography between emergency medicine (EM) residents and remote experts in diagnosing acute appendicitis. METHODS This prospective observational study was performed in an academic emergency department. Beginning in June 2014, the EM residents performed the initial ultrasonography for(More)
To examine the use of online social networking for cardiovascular care using Facebook. All posts and comments in a Facebook group between June 2011 and May 2012 were reviewed, and a survey was conducted. A total of 298 members participated. Of the 277 wall posts, 26.7% were question posts requesting rapid replies, and 50.5% were interesting cases shared(More)
OBJECTIVE This study investigates the availability and frequency of emergency physician-performed ultrasonography (USG) in the emergency department (ED) and the status of USG training programs in emergency medicine residencies in academic EDs in Korea. METHODS In spring 2014, a link to a 16-question, multiple-choice, and rating scale web-based survey was(More)
We investigated the feasibility of the clinical application of novice-practitioner-performed/offsite-mentor-guided ultrasonography for identifying the appendix. A randomized crossover study was conducted using a telesonography system that can transmit the ultrasound images displayed on the ultrasound monitor (ultrasound sequence video) and images showing(More)
OBJECTIVE We examined the pain-relieving effect of ultrasound-guided regional anesthesia performed by emergency physicians on elderly hip fracture patients. METHODS This study is a prospective, non-randomized, case-control study. The subjects were patients older than 65 years who visited the emergency department with a hip fracture. After we obtained(More)
