Rapid and accurate diagnosis and treatment are paramount in the management of the critically ill. Critical care ultrasound has been widely used as an adjunct to standard clinical examination, an invaluable extension of physical examination to guide clinical decision-making at bedside. Recently, there is growing interest in the use of multi-organ point-of-care ultrasound (MOPOCUS) for the management of the critically ill, especially in the early phase of resuscitation. This article will review the role and utility of symptom-based and sign-oriented MOPOCUS in patients with undifferentiated respiratory difficulty, chest pain, or shock and how it can be performed in a timely, effective, and efficient manner.

Purpose: Cervical traumas are frequent in emergency department and X-ray, CT, and MRI are the essential imaging modalities in the diagnosis. However, especially for pregnant and morbid obese patients and children, these techniques can be challenging. We tested the success of point-of-care ultrasound in the evaluation of cervical traumas. Methods: This is a case series of cervical vertebra imaging with ultrasound in emergency department. We used linear probe and placed it anterolaterally to the neck, parallel to cervical spine. Images were obtained by an ultrasound-certified emergency physician. The height of the anterior wall of vertebral body, irregularity in vertebral body, and intervertebral space were assessed. Results: We presented a case series of six patients. Ultrasound images of cervical vertebral bodies and intervertebral spaces were able to obtain for all the patients. Any pathology was not observed in ultrasound imaging. This finding was compatible with cervical X-ray and CT scans and all the patients were discharged. Conclusions: However, this is a case series report of minor cervical trauma, and we were able to obtain ultrasound images of cervical vertebra bodies with point-of-care ultrasound examination by an emergency physician. This technique can be important for the patients contraindicated to CT or MRI. Also, it can give additional information to X-ray and CT scans especially for soft tissues.

Purpose: The purpose of this paper is to assess the experience and satisfaction of the trainees participating in the Emergency Pediatric Ultrasound Training Course, which has been developed from a close cooperation between the Korean Society of Pediatric Emergency Medicine and Society of Emergency and Critical Care Imaging.Methods: A task-force team was formed consisting of 8 members, collectively from both Korean Society of Pediatric Emergency Medicine and Society of Emergency and Critical Care Imaging. Over 9 separate discussion sessions, the team reviewed related articles to reach a consensus on an educational framework, a curriculum for the training course, and teaching methods to adapt to the conditions of Pediatric Emergency Medicine in South Korea. Results:After running the course twice with a developed curriculum, the trainees were polled for their training experiences. A total of 36 trainees completed the course. The response rates were 81.3% and 40% in the first and second course, respectively. On average, the ratings by participants in the survey were above a 4 for all questions, which are significantly high scores. Over sixty percent of participants rated 4 or above in the Likert scale for all of the questions. Conclusion: Korean Society of Pediatric Emergency Medicine and Emergency Imaging Study Group (now renamed toSociety of Emergency & Critical Care Imaging) successfully developed the Emergency Pediatric Ultrasound Course, which was rated significantly favorably by the trainees.
