Accidental Hypothermia in a Swiss Alpine Trauma Centre-Not an Alpine Problem.

BACKGROUND Research in accidental hypothermia focuses on trauma patients, patients exposed to cold environments or patients after drowning but rarely on hypothermia in combination with intoxications or on medical or neurological issues. The aim of this retrospective single-centre cohort study was to define the aetiologies, severity and relative incidences of accidental hypothermia, methods of measuring temperature and in-hospital mortality. METHODS The study included patients ≥18 years with a documented body temperature ≤35 °C who were admitted to the emergency department (ED) of the University Hospital in Bern between 2000 and 2019. RESULTS 439 cases were included, corresponding to 0.32 per 1000 ED visits. Median age was 55 years (IQR 39-70). A total of 167 patients (38.0%) were female. Furthermore, 63.3% of the patients suffered from mild, 24.8% from moderate and 11.9% from severe hypothermia. Exposure as a single cause for accidental hypothermia accounted for 12 cases. The majority were combinations of hypothermia with trauma (32.6%), medical conditions (34.2%), neurological conditions (5.2%), intoxications (20.3%) or drowning (12.0%). Overall mortality was 22.3% and depended on the underlying causes, severity of hypothermia, age and sex

Data and methods to calculate cut-off values for serum potassium and core temperature at hospital admission for extracorporeal rewarming of avalanche victims in cardiac arrest.

The data and estimation methods presented in this article are associated with the research article, "Cut-off values of serum potassium and core temperature at hospital admission for extracorporeal rewarming of avalanche victims in cardiac arrest: a retrospective multi-centre study" [1]. In this article we estimate recommended cut-off values for in-hospital triage with respect to extracorporeal rewarming. With only 6 survivors of 103 patients collected over a period of 20 years the ability to estimate reliable threshold values is limited. In addition, because the number of avalanche victims is also limited, a significantly larger dataset is unlikely to be obtained. We have therefore adapted two non-parametric estimation methods (bootstrapping and exact binomial distribution) to our specific needs and performed a simulations to confirm validity and reliability

Interprofessional and interdisciplinary simulation-based training leads to safe sedation procedures in the emergency department

BACKGROUND Sedation is a procedure required for many interventions in the Emergency department (ED) such as reductions, surgical procedures or cardioversions. However, especially under emergency conditions with high risk patients and rapidly changing interdisciplinary and interprofessional teams, the procedure caries important risks. It is thus vital but difficult to implement a standard operating procedure for sedation procedures in any ED. Reports on both, implementation strategies as well as their success are currently lacking. This study describes the development, implementation and clinical evaluation of an interprofessional and interdisciplinary simulation-based sedation training concept. METHODS All physicians and nurses with specialised training in emergency medicine at the Berne University Department of Emergency Medicine participated in a mandatory interdisciplinary and interprofessional simulation-based sedation training. The curriculum consisted of an individual self-learning module, an airway skill training course, three simulation-based team training cases, and a final practical learning course in the operating theatre. Before and after each training session, self-efficacy, awareness of emergency procedures, knowledge of sedation medication and crisis resource management were assessed with a questionnaire. Changes in these measures were compared via paired tests, separately for groups formed based on experience and profession. To assess the clinical effect of training, we collected patient and team satisfaction as well as duration and complications for all sedations in the ED within the year after implementation. We further compared time to beginning of procedure, time for duration of procedure and time until discharge after implementation with the one year period before the implementation. Cohen's d was calculated as effect size for all statistically significant tests. RESULTS Fifty staff members (26 nurses and 24 physicians) participated in the training. In all subgroups, there is a significant increase in self-efficacy and knowledge with high effect size (d z  = 1.8). The learning is independent of profession and experience level. In the clinical evaluation after implementation, we found no major complications among the sedations performed. Time to procedure significantly improved after the introduction of the training (d = 0.88). DISCUSSION Learning is independent of previous working experience and equally effective in raising the self-efficacy and knowledge in all professional groups. Clinical outcome evaluation confirms the concepts safety and feasibility. CONCLUSION An interprofessional and interdisciplinary simulation-based sedation training is an efficient way to implement a conscious sedation concept in an ED

Medical aspects of the Gorkha earthquake 2015: disaster preparedness and response

This chapter includes exemplary accounts from two medical doctors pertaining to the situation in the capital and in remote valleys. Within both accounts, the authors describe their personal experience, beginning with the first few hours post the initial quake. These experiences are firsthand accounts, ranging from uncoordinated medical aid in a governmental hospital in Kathmandu and a mountain hospital in Lukla to the ad hoc rescue chain in the Khumbu valley for those victims coming predominantly from Everest Base Camp. Unfortunately, the threat of future earthquakes and other natural hazard events in Nepal cannot be diminished. Therefore, in order to better manage any future mass casualty event, it is clear that there is a pressing need for further development of medical and rescue training services for both existing practitioners in the capital and those individuals based in rural Nepal. Moreover, the development of an international, coordinative body with rapid response time and specialist skill base must be discussed and deployed effectively in the case of any future national emergency

Initiative zur Implementierung von Planetary Health in die ärztliche Fort- und Weiterbildung in der Schweiz

The Swiss Medical Association FMH drew up the strategy "Planetary health - Strategy on the courses of action on climate change for the medical profession in Switzerland" in collaboration with the Swiss Institute for Medical Education SIME, the umbrella organisations and students. On 7 October 2021, the strategy was approved by the Swiss Medical Chamber with a budget of over CHF 380,000 (approx Euro 365,000). The first step in implementation involved setting up an advisory group which will tackle the concrete implementation of the strategy. This article provides an insight into the current state of work on the project with a focus on the measures in the areas of postgraduate medical training and continuing medical education. It is a work in progress.Die Verbindung der Schweizer Ärztinnen und Ärzte FMH hat die Strategie "Planetary Health - Strategie zu den Handlungsmöglichkeiten der Ärzteschaft in der Schweiz zum Klimawandel" in Zusammenarbeit mit dem Schweizerischen Institut für ärztliche Weiter- und Fortbildung SIWF, den Dachverbänden und den Studierenden verfasst. Am 7. Oktober 2021 wurde die Strategie von der Ärztekammer der FMH mit einem Budget über ca. 380'000 CHF (ca. 365'000 Euro) verabschiedet.

Wilderness Mass Casualty Incident (MCI): rescue chain after avalanche at Everest Base Camp (EBC) in 2015

The Nepal Earthquake of 2015 killed over 8000 people and injured over 20,000 in Nepal. Moments after the earthquake, an avalanche of falling ice came down from above Everest Base Camp (EBC). The air blast created by the avalanche flattened the middle part of EBC, killing 15 people and injuring at least 70. The casualties were initially triaged and treated at EBC and then evacuated by air to Kathmandu for definitive care. There were intermediate stops at the villages of Pheriche and Lukla during which the casualties were offloaded, retriaged, treated, and loaded again for further transport. Most of the authors of this article helped to provide primary disaster relief at EBC, Pheriche, or Lukla immediately after the earthquake. We describe the process by which an ad hoc rescue chain evacuated the casualties. We discuss challenges, both medical and nonmedical, what went well, and lessons learned. We make recommendations for disaster planning in the Khumbu (Everest) region, an isolated high altitude roadless area of Nepal

Multiple trauma management in mountain environments - a scoping review : Evidence based guidelines of the International Commission for Mountain Emergency Medicine (ICAR MedCom). Intended for physicians and other advanced life support personnel.

BACKGROUND Multiple trauma in mountain environments may be associated with increased morbidity and mortality compared to urban environments. OBJECTIVE To provide evidence based guidance to assist rescuers in multiple trauma management in mountain environments. ELIGIBILITY CRITERIA All articles published on or before September 30th 2019, in all languages, were included. Articles were searched with predefined search terms. SOURCES OF EVIDENCE PubMed, Cochrane Database of Systematic Reviews and hand searching of relevant studies from the reference list of included articles. CHARTING METHODS Evidence was searched according to clinically relevant topics and PICO questions. RESULTS Two-hundred forty-seven articles met the inclusion criteria. Recommendations were developed and graded according to the evidence-grading system of the American College of Chest Physicians. The manuscript was initially written and discussed by the coauthors. Then it was presented to ICAR MedCom in draft and again in final form for discussion and internal peer review. Finally, in a face-to-face discussion within ICAR MedCom consensus was reached on October 11th 2019, at the ICAR fall meeting in Zakopane, Poland. CONCLUSIONS Multiple trauma management in mountain environments can be demanding. Safety of the rescuers and the victim has priority. A crABCDE approach, with haemorrhage control first, is central, followed by basic first aid, splinting, immobilisation, analgesia, and insulation. Time for on-site medical treatment must be balanced against the need for rapid transfer to a trauma centre and should be as short as possible. Reduced on-scene times may be achieved with helicopter rescue. Advanced diagnostics (e.g. ultrasound) may be used and treatment continued during transport
