To describe all patients treated for out-of-hospital cardiac arrest (OHCA) according to the Utstein criteria and their characteristics and outcome with emphasis on whether they were available for early intervention trials. ⋯ Among patients with OHCA in whom CPR was started 8.5% survived to hospital discharge and 59% were theoretically available for an early intervention trial. These patients have a different outcome compared with patients not available. However, among those available, the majority of survivors had a rapid ROSC before the application of the intervention (LUCAS). This raises concerns about the potential for early intervention trials to improve outcome after OHCA.

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.

Comparative Study
Sustained abdominal compression during CPR raises coronary perfusion pressures as much as vasopressor drugs.
This study investigated sustained abdominal compression as a means to improve coronary perfusion pressure (CPP) during cardiopulmonary resuscitation (CPR) and compared the resulting CPP augmentation with that achieved using vasopressor drugs. ⋯ During CPR noninvasive abdominal compression with the inflatable contoured cuff rapidly elevates the CPP, sustains the elevated CPP as long as the device is inflated, and is immediately and controllably reversible upon device deflation. Physical control of peripheral vascular resistance during CPR by abdominal compression has some advantages over pharmacological manipulation and deserves serious reconsideration, now that the limitations of pressor drugs during CPR have become better understood, including post-resuscitation myocardial depression and the need for intravenous access.

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.

This report describes a case of out-of-hospital cardiac arrest with spontaneous defibrillation and subsequent return of circulation after cessation of resuscitative efforts. A 47-year-old man was found in cardiac arrest and resuscitation was initiated. ⋯ The patient made a poor neurological recovery and died 3 months after the arrest. The authors are unable to give an explanation to the event, but suspect the effect of adrenaline combined with mild hypothermia to have contributed to the self-defibrillation of the myocardium.
