Tracheal intubation is often difficult in the prehospital setting, especially in trapped casualties, when long extrication time is anticipated and conventional laryngoscopy cannot be achieved. The aim of the present study was the comparison of applicability and efficacy of two alternative techniques: intubation using a laryngeal mask airway (ILMA) or an Airtraq laryngoscope in different patient positions, using an airway management manikin. ⋯ These preliminary data in manikins could indicate the applicability of the methods to the prehospital setting.

A principal reason to order a head CT scan for dizziness patients is to exclude stroke. As CT imaging is substantially limited in assessing for any acute lesions other than haemorrhage, the most important stroke syndrome adequately evaluated by CT is intracerebral haemorrhage (ICH). A population based stroke database was used to assess the frequency with which ICH might mimic a benign dizziness presentation. ⋯ This study provides further support for the notion that ICH is highly unlikely to mimic a benign dizziness presentation. Coupled with the limitations of CT to show acute ischaemia in the posterior fossa, these results suggest that screening for ICH may not be necessary in benign appearing dizziness presentations although more research is needed.

Isolated posterior ST-elevation myocardial infarction (STEMI) accounts for up to 7% of STEMIs. The diagnosis is suggested by indirect anterior-lead ECG changes. Confirmation requires presence of ST-elevation in posterior-leads (V7-V9). We investigated the ability of hospital doctors and paramedics to diagnose posterior STEMI (PMI). ⋯ A significant proportion of doctors and paramedics were unable to diagnose PMI. Hence, the majority of PMIs may be being missed. Routine use of posterior-leads in the standard assessment of patients with chest pain may identify up to an additional 7% of STEMIs, allowing prompt reperfusion therapy, which would reduce morbidity and mortality.
