"Should we be giving blood transfusions to patients with traumatic cardiac arrest?" EMJ editor Prof. Richard Body and associate editor Dr. Sarah Edwards talk through some original research on the value of blood transfusions in this difficult situation. Next is the new UNCORKED study from the Trainee Emergency Research Network (TERN), with some sobering statistics on the prevalence of emergency care carried out in non-standard treatment places across the UK. Then we move to a world of high-pressure injuries, often caused by industrial spraying equipment, where things on the surface aren't quite as they seem. The last paper returns to the theme of cardiac arrests, examining the predictive value of end-tidal CO2 usage. Read the highlights: Primary survey:

• The association of blood transfusion and sustained return of spontaneous circulation in blunt traumatic out-of-hospital cardiac arrest
• Understanding corridor and escalation area care in 165 UK emergency departments: a multicentre cross-sectional snapshot study
• Recognising high-pressure injection injuries to the hand: a practice review with guidance for emergency physicians
• Prognostic accuracy of end-tidal carbon dioxide in cardiac arrest: a systematic review and meta-analysis
