Most emergency departments in Scotland are now administering thrombolysis for patients with acute myocardial infarction. Thrombolysis, delivered either in the prehospital arena or in the emergency department, is likely to be the primary option for patients with acute myocardial infarction in Scotland in the foreseeable future.

Our results show that almost half of our colleagues would have carried out tube thoracostomy when no pneumothorax was actually present. In a situation where a pneumothorax is a clinical possibility we would recommend either temporarily removing the oxygen mask if clinically stable, or fixing the reservoir bag outwith the field of the CXR by means of adhesive tape to avoid any misinterpretation of this 'mask sign'.
