Ultrasound (US) has been used for in-hospital evaluation of the trauma victim for many years. The outcome in severely injured patients remains heavily influenced by initial life support and early care, as time plays a major role. Development of handheld, battery-powered, low-weight US machines has created the possibility of bringing US to the prehospital setting, thus gaining a potential for early diagnosis and treatment. ⋯ Several studies in this review showed that prehospital US is feasible and that the procedure is highly reliable in detection of haemoperitoneum or haemopericardium compared with the low accuracy of physical examination and haemodynamic measurements. An early diagnosis will provide the prehospital physician with the knowledge to prioritize the relevant initial treatment and to choose the closest appropriate hospital and transportation form. There is currently no evidence in the literature that prehospital US of the abdomen or thorax improves treatment of trauma patients.

Emergency service workers continuously face situations where they are in charge of the lives of others, and this can be a risk factor for their mental health. This study aims to determine the psychological impact of exposure to current death and physical injury events in the context of motor vehicle accidents among emergency personnel and which variables better predict posttraumatic stress disorder. Participants were National Institute of Medical Emergency workers (nurses and medical doctors; n= 59) in the north of Portugal. ⋯ Participants reported high exposure to events evaluated as traumatic, but low prevalence of PTSD. When the relation between exposure, time in emergency, sex, distress symptoms, peritraumatic dissociation, and PTSD symptoms was examined, peritraumatic dissociation and distress were the only predictors of PTSD symptoms, but beyond their contribution direct coping explains PTSD variance. In conclusion, taking into account the contribution of distress and peritraumatic dissociation to predict psychopathological symptoms, and the contribution of coping to lower PTSD scores, education and training should help the professionals deal with these reactions and improve coping, and organizations should support professionals in the most disturbing situations.

Prehospital ultrasound in emergency medicine: incidence, feasibility, indications and diagnoses.
Sonography is an established diagnostic procedure in hospitals, but is not routinely used in prehospital emergency medicine. Several studies have addressed the use of ultrasound during helicopter flights and in emergency rooms, few in prehospital settings, but most focused on abdominal blunt trauma. Several case reports describe crucial decisions distinguished by ultrasound. ⋯ Ultrasound is the only imaging modality and a useful diagnostic tool in prehospital emergency medicine. Helpful information can be provided in at least one of six cases (or even more) in a trauma-dominated collective. Examination time is short; it will not significantly delay medical care. Ultrasound examination could improve triage in cases of more than one patient in disaster medicine, but further studies are necessary.

The primary purpose of this prospective cohort study was to characterize the use of the Emergency Department (ED) in patients with chronic obstructive pulmonary disease (COPD) exacerbations and determine the factors affecting the revisit of COPD patients. This is a prospective cohort study on ambulatory patients with exacerbated chronic bronchitis in an ED setting. Patients included in the study were above 18 years of age, had a previous diagnosis of COPD, and presented to the ED for the treatment of COPD exacerbation. ⋯ Home oxygen therapy, intensive care admission, previous intubation, increased cough, and the number of ED visits in the previous year were associated with increased risk of revisit in the univariate analysis. Increased cough (odds ratio: 0.232; 95% confidence interval: 0.063-0.853) and the number of ED visits in the previous year (odds ratio: 1.166; 95% confidence interval: 1.005-1.353) were still significant after multivariate analysis. In conclusion, the number of ED visits previous year and increased cough can predict the revisit of a COPD exacerbated patient within 14 days of an ED visit.
