Knowledge about epidemiology, rewarming treatments, complications and outcome is limited. This study was initiated to obtain data on causes, rewarming treatments and complications. A retrospective cohort study of all patients with a body temperature ≤ 35°C admitted to the Emergency Department (ED) of the VU university medical centre, Amsterdam, The Netherlands, between January 1, 2000 and August 31, 2008. A predefined set of epidemiological and clinical data was retrieved. Eighty-four patients were included (median age: 47 years). Categories of hypothermia included immersion (18), submersion (29) and exposure to cold (37); concomitant factors were intoxication (26), trauma (40) and homelessness (7). Temperature at admission in the ED was 31.6 ± 2.6°C (mean ± SD), lowest temperature 24.2°C. Fourteen different rewarming treatments were used resulting in a wide range of rewarming speeds. Seventy-nine complications...

This has not previously been investigated for AED-training. Materials and methods: This prospective, randomized study with a non-inferiority design compared traditional instructor-led training with three DVD-based AED-training methods (2.5 min DVD without practice; 4.5 min DVD with manikin practice; 9 min DVD with manikin practice and scenario training). After DVD BLS-training, 396 participants were assigned to one of the four AED-training methods by randomization stratified for age.

After the café fire in Volendam, the Netherlands, on New Year's Eve 2000, around 200 rescue workers were deployed on-site. The aim of this study is to investigate the rescue workers' experiences with regard to their level of preparation for the emergency response. In 2002, 30 members of the medical and paramedical personnel were requested to participate in a structured interview, focused on education, task perception, triage and registration. Twenty-seven participated. Twenty-two rescue workers received previous training in emergency medicine. During the alarm phase, 11 rescue workers had a clear perception of their tasks. Twenty-four were involved in triage and injury assessment. Three rescue workers used a protocol for triage and 15 for injury assessment. Twenty-five rescue workers gave on-scene treatment and 15 used a protocol. Eight registered their findings. Preparation for the emergency response lacked standardized procedures. The use of triage protocols was extremely poor, as was documentation of actions. Slightly more than half of the personnel followed treatment protocols. It is advisable that all rescue workers become familiar with the basic uniform principles and protocols regarding disaster management. A dedicated and standardized national disaster management course is needed for all rescue workers.
