Within Europe and North America, the median annual mortality from snow avalanches between 1994 and 2003 was 141. There are two commonly used rescue devices: the avalanche transceiver, which is intended to speed up locating a completely buried person, and the avalanche airbag, which aims to prevent the person from being completely buried. ⋯ Our data showed that both the avalanche airbag and the avalanche transceiver reduce mortality. However, to improve the evaluation of rescue devices in the future, the data collection procedures should be reviewed and prospective trials should be considered, as the reliability of retrospective studies is limited.

Randomized Controlled Trial Multicenter Study Comparative Study
Advanced life support cardiac arrest scenario test evaluation.
The cardiac arrest scenario test (CASTest) is a central component of the assessment strategy on the Advanced Life Support Course. The aim of this study was to establish equivalence between the four different CASTest scenarios and investigate the impact of profession, candidate order and course centre on the pass rate. ⋯ The CASTest assessment scenarios used during ALS testing appear equivalent in terms of difficulty. In contrast, the professional background of the candidate and centre at which the assessment is performed do significantly influence the likelihood of passing the assessment. Further evaluation of the reasons for differences between course centres is required.

Review Case Reports
Acute respiratory failure leading to emergency intubation: an unusual manifestation of Munchausen's syndrome.
Munchausen's syndrome is a contrived psychiatric disorder, in which patients present with an intentionally produced or feigned illness with the aim to assume the sick role and to gain medical attention. Patients may even seek the application of invasive procedures, sometimes with serious risk to life. ⋯ This case report may contribute to the awareness among emergency physicians of Munchausen's syndrome as a differential diagnosis of respiratory failure. Recognition of this psychiatric disease is not only important for correct medical diagnosis and treatment, but also essential in protecting the patients from unnecessary invasive and aggressive medical procedures.

To evaluate the frequency, presentation, treatment and outcome of cardiopulmonary resuscitation-associated major liver injury in patients after non-traumatic in- or out-of-hospital cardiac arrest. ⋯ Our single centre observation confirms that resuscitation-associated major liver injury is infrequent and shows that most patients had compromised haemostasis. Low or dropping haematocrit should trigger suspicion. Bedside sonography reveals intra-peritoneal fluid or liver injury. A conservative therapeutic approach or emergency surgery may be warranted. Major liver injury alone scarcely appears to influence overall outcome.

Mechanical chest compression may be necessary to make coronary intervention possible during resuscitation. We report our experience using the Lund University Cardiac Arrest System (LUCAS, Jolife, Lund, Sweden) which is a gas-driven sternal compression device that incorporates a suction cup for active decompression. During the last 13 months LUCAS has been used in our catheterisation laboratory to maintain adequate organ perfusion pressure in 13 patients with cardiac arrest or severe hypotension and bradycardia (male/female ratio 1.6, mean age 59+/-19). ⋯ In two cases we found inadequate flow in the anterior descending artery, and in one case the invasive measurements revealed inadequate coronary perfusion pressure. There were no excessive intra-thoracic or intra-abdominal injuries. We conclude that the LUCAS device is suitable during cardiac catheterisation and intervention, and the device ensures an adequate systemic blood pressure in most patients without life-threatening injuries.
