Multicenter Study Comparative Study
Review of the composition and use of trauma teams within the Trent Region.
The aim of the study was to find the existence, composition and working policies of trauma teams within the Trent Region. Data were obtained by postal survey. Despite many reports indicating a need for a unified multidisciplinary approach to trauma management, this study found that this approach was absent in many hospitals.

Comparative Study
Management of minor head injuries in the accident and emergency department: the effect of an observation ward.
The management of 483 patients presenting with minor head injury to the accident and emergency (A&E) departments of two Scottish hospitals was studied prospectively. Such patients comprised 5.7 and 3.9% of the total attendances to each department. Of the 277 patients assessed in the former department, 83 (30%) fulfilled at least one of the currently accepted criteria for recommending admission to hospital and 49 (17.7%) patients were actually admitted. ⋯ However, significantly fewer, 10 (4.9%) patients, were actually admitted. The major relevant factor when comparing the two departments was the existence in the former of an observation ward. These results support the view that easy access to hospital beds is a major determinant of management in patients presenting with minor head injury to the A&E department and may be more influential than clinical findings.

Transoesophageal echocardiography (TOE) was performed during closed chest cardiopulmonary resuscitation (CPR) in 18 subjects in cardiac arrest. Compression of all four cardiac chambers resulted in forward flow in the pulmonary and systemic circulations, retrograde pulmonary vein flow and incomplete mitral valve closure. ⋯ These findings support the cardiac pump theory of CPR and are incompatible with the thoracic pump mechanism. TOE merits further investigation as a device to monitor and guide resuscitation efforts during CPR.

Case Reports Comparative Study
Aluminium ring pulls: an invisible foreign body.
The aluminium ring pulls associated with the latest designs of drinks cans can be relatively easily detached from their mounting on the top of the can and subsequently aspirated. Their small size predisposes them to lodge as foreign bodies (FBs) in the throat. The similarity of atomic number between soft tissue (7.5) and aluminium (13) makes detection of these FBs difficult on soft tissue radiography. If aspiration is suspected direct visualization and removal may be indicated even if radiography is negative.

Comparative Study
Analysis of emergency department interpretation of electrocardiograms.
The objective of the study was to determine the concordance of emergency physicians' and cardiologists' interpretations of emergency department (ED) electrocardiograms (ECG), to evaluate the impact of ECG misinterpretation on patient management, and to determine error rates as a function of the level of physician training and the specific ECG diagnoses. ECG interpretations were registered prospectively using a programmed-response data sheet. A second blinded interpretation by a staff cardiologist was assumed to be correct. ⋯ While discordance was significant, errors in ECG interpretation rarely impacted patient management. Prospective evaluation of ECG interpretation may be a useful means of gauging physician skills. It can also serve to focus educational activities on problem areas in electrocardiography.
