Point-of-care echocardiography using portable machines is an exciting development in emergency medicine. Recent improvements in ultrasound quality mean that emergency physicians are finding echocardiography useful in a variety of clinical settings. ⋯ Patients with clinical conditions such as breathlessness, undifferentiated shock, chest pain and cardiac arrest may benefit. There is a steep learning curve involved in acquiring these skills and the specialty needs to take care in the way that its practitioners are accredited and perform echocardiography.

Multicenter Study
Coma and impaired consciousness in the emergency room: characteristics of poisoning versus other causes.
Unconscious patients represent a diagnostic challenge in the emergency room (ER), but studies on their characteristics are limited. The aim of this study was to investigate the frequency, characteristics and prognosis of different coma aetiologies with special focus on poisoning. ⋯ Poisoning was the most common cause of coma and young age was a strong predictor of this condition. The prognosis was favourable among poisoned patients but poor in the rest of the study population as a group.

Multicenter Study
Influence of air ambulance doctors on on-scene times, clinical interventions, decision-making and independent paramedic practice.
Critics of air ambulance doctors question their contribution and believe on-scene time is prolonged. Two helicopter emergency medical service (HEMS) models operate in the West Midlands, one with doctors and the other without. A study was undertaken to compare on-scene time, management and decision-making between the two units. ⋯ Appropriately trained HEMS doctors provide advanced management and decision-making. This is without a negative effect on on-scene time, even when performing complex procedures. They are more likely to declare death or discharge patients at the scene, increasing the availability of this limited resource.

The thrombolysis in myocardial infarction (TIMI) risk score has been shown to risk stratify patients with suspected acute coronary syndromes (ACS) effectively in the emergency department (ED) but cannot be used to guide patient disposition. We aimed to evaluate whether modifying the TIMI risk score to give greater weighting to ischaemic ECG changes and troponin elevations would enhance its risk stratification and thus potentially facilitate safe patient discharge after 12-h troponin testing. ⋯ Modifications to the TIMI risk score can improve its performance in the risk stratification of patients presenting to the ED with chest pain. However, a lack of specificity may still limit its use for guiding patient disposition after troponin testing.

Randomized Controlled Trial
The usefulness of the GlideScope video laryngoscope in the education of conventional tracheal intubation for the novice.
The aim of this study is to evaluate the usefulness of the GlideScope video laryngoscope (GVL) as a tool to educate novice users in conventional tracheal intubation. 41 premedical students with no previous experience in tracheal intubation participated in this prospective, randomised and controlled study. Group M (n = 20) was instructed in tracheal intubation by using the Macintosh laryngoscope and group G (n = 21) was instructed by using both the GVL and the Macintosh laryngoscope. ⋯ This aspect makes the trainee feel more comfortable learning the material with a high degree of satisfaction. Introducing GVL to conventional intubation education for novice users could increase the satisfaction of trainees during the procedure, especially as a way to understand critical anatomical structures.
