Abstract
Standardized reporting of data is crucial for out-of-hospital cardiac arrest (OHCA) research. While the implementation of first responder systems dispatching volunteers to OHCA is encouraged, there is currently no uniform reporting standard for describing these systems. A steering committee established a literature search to identify experts in smartphone alerting systems. These international experts were invited to a conference held in Hinterzarten, Germany, with 40 researchers from 13 countries in attendance. Prior to the conference, participants submitted proposals for parameters to be included in the reporting standard. The conference comprised five workshops covering different aspects of smartphone alerting systems. Proposed parameters were discussed, clarified, and consensus was achieved using the Nominal Group Technique. Participants voted in a modified Delphi approach on including each category as a core or supplementary element in the reporting standard. Results were presented, and a writing group developed definitions for all categories and items, which were sent to participants for revision and final voting using LimeSurvey web-based software. The resulting reporting standard consists of 68 core items and 21 supplementary items grouped into five topics (first responder system, first responder network, technology/algorithm/strategies, reporting data, and automated external defibrillators (AED)). This proposed reporting standard generated by an expert opinion group fills the gap in describing first responder systems. Its adoption in future research will facilitate comparison of systems and research outcomes, enhancing the transfer of scientific findings to clinical practice.

Abstract
Approximately 10% of patients resuscitated from out-of-hospital cardiac arrest survive to hospital discharge. Improved management to improve outcomes is required, and it is proposed that such patients should be preferentially treated in cardiac arrest centres. The minimum requirements of therapy modalities for the cardiac arrest centre are 24/7 availability of an on-site coronary angiography laboratory, an emergency department, an intensive care unit, imaging facilities such as echocardiography, computed tomography and magnetic resonance imaging, and a protocol outlining transfer of selected patients to cardiac arrest centres with additional resources (out-of-hospital cardiac arrest hub hospitals). These hub hospitals are regularly treating a high volume of patients and offer further treatment modalities. This consensus document describes the aims, the minimal requirements for therapeutic modalities and expertise, and the structure, of a cardiac arrest centre. It represents a consensus among the major European medical associations and societies involved in the treatment of out-of-hospital cardiac arrest patients.

Abstract
Approximately 10% of patients resuscitated from out-of-hospital cardiac arrest (OHCA) survive to hospital discharge. Improved management to improve outcomes are required, and it is proposed that such patients should be preferentially treated in cardiac arrest centres (CACs).

Abstract
Complex intubation, cricothyrotomy and tracheotomy. Successful management of a difficult airway begins with recognizing the potential problem. When the patient cannot breathe spontaneously, oxygenation and ventilation should start first with bag-valve ventilation, with or without an airway adjunct such as a Mayo cannula, followed by an orotrache4l intubation attempt, performed by an experienced emergency doctor. If orotracheal intubation fails, a quick decision must be made regarding surgical options. In a "cannot intubate, cannot ventilate" situation, a surgical cricothyrotomy should be considered. When orotracheal intubation is impossible, but bag-valve or laryngeal mask ventilation is possible, an urgent surgical tracheostomy should be performed. In the long run, patients in need of longterm artificial ventilation will need a percutaneous or open tracheostomy. This review provides an update of all aspects of immediate and long-term airway management.

Abstract
OBJECTIVE Automated external defibrillators (AEDs) placed in public locations can save lives of cardiac arrest victims. In this paper, we try to estimate the cost-effectiveness of AED placement in Belgian schools. This would allow school policy makers to make an evidence-based decision about an on-site AED project. METHODS AND RESULTS We developed a simple mathematical model containing literature data on the incidence of cardiac arrest with a shockable rhythm; the feasibility and effectiveness of defibrillation by on-site AEDs and the survival benefit. This was coupled to a rough estimation of the minimal costs to initiate an AED project. According to the model described above, AED projects in all Belgian schools may save 5 patients annually. A rough estimate of the minimal costs to initiate an AED project is 660 EUR per year. As there are about 6000 schools in Belgium, a national AED project in all schools would imply an annual cost of at least 3960 000 EUR, resulting in 5 lives saved. CONCLUSIONS As our literature survey shows that AED use in schools is feasible and effective, the placement of these devices in all Belgian schools is undoubtedly to be considered. The major counter-arguments are the very low incidence and the high costs to set up a school-based AED programme. Our review may fuel the discussion about Whether or not school-based AED projects represent good value for money and should be preferred above other health care interventions.

Abstract
INTRODUCTION Schoolteachers are expected to play a role in teaching cardiopulmonary resuscitation (CPR) to schoolchildren, but little is known about their attitudes, actual knowledge and willingness to do so. We conducted a survey about CPR knowledge, preparedness to perform and teach CPR as well as attitude towards an alternative self-learning strategy amongst Flemish teachers. METHODS A questionnaire was developed consisting of four distinct parts: (1) Demographics; (2) CPR knowledge and skills level; (3) Attitude towards training and (4) Resuscitation experience. Content experts screened the questionnaire in view of content validity. One hundred and seventy-one students in Educational Sciences were each asked to interview 25 different teachers. RESULTS A total of 4273 teachers participated in the study (primary school n=856; secondary school n=2562; higher education n=855). Of all respondents, 59% (2539/4273) had received previous CPR training with the highest proportion observed in primary schoolteachers (69%) and in the age group 21-30 years (68%). Mandatory CPR training at school was supported by 41% (1751/4273) of the teachers and only 36% was aware that CPR is now formally included in the secondary education curriculum. Sixty-one percent (2621/4273) did not feel capable and was not willing to teach CPR, mainly because of a perceived lack of knowledge in 50% (2151/2621). In addition 69% (2927/4273) felt incompetent to perform correct CPR and 73% (3137/4273) wished more training. Feeling incompetent and not willing to teach was related to the absence of previous training. Primary schoolteachers and the age group 21-30 years were most willing to teach CPR. CONCLUSIONS Although many teachers mentioned previous CPR training, only a minority of mostly young and primary schoolteachers felt competent in CPR and was willing to teach it to their students.

Abstract
AIM Our objectives were to determine the most effective, safe, and feasible first aid (FA) techniques and procedures, and to formulate valid recommendations for training. We focussed on emergencies involving few casualties, where emergency medical services or healthcare professionals are not immediately present at the scene, but are available within a short space of time. Due to time and resource constraints, we limited ourselves to safety, emergency removal, psychosocial FA, traumatology, and poisoning. Cardiopulmonary resuscitation (CPR) was not included because guidelines are already available from the European Resuscitation Council (ERC). The FA guidelines are intended to provide guidance to authors of FA handbooks and those responsible for FA programmes. These guidelines, together with the ERC resuscitation guidelines, will be integrated into a European FA Reference Guide and a European FA Manual. METHODS To create these guidelines we used an evidence-based guideline development process, based on the methodology of the Scottish Intercollegiate Guidelines Network (SIGN). RESULTS The recommendations cover FA for bleeding, wounds, burns, spinal and head trauma, musculoskeletal trauma, and poisoning, as well as safety and psychosocial FA. CONCLUSIONS Where good evidence was available, we were able to turn science into practice. Where evidence was lacking, the recommendations were consensus-based. These guidelines provide systematically developed recommendations and justifications for the procedures and techniques that should be included in FA manuals and training programmes.

Abstract
Outcome after cardiac arrest and cardiopulmonary resuscitation is dependent on critical interventions, particularly early defibrillation, effective chest compressions, and advanced life support. Utstein-style definitions and reporting templates have been used extensively in published studies of cardiac arrest, which has led to greater understanding of the elements of resuscitation practice and progress toward international consensus on science and resuscitation guidelines. Despite the development of Utstein templates to standardize research reports of cardiac arrest, international registries have yet to be developed. In April 2002, a task force of the International Liaison Committee on Resuscitation (ILCOR) met in Melbourne, Australia, to review worldwide experience with the Utstein definitions and reporting templates. The task force revised the core reporting template and definitions by consensus. Care was taken to build on previous definitions, changing data elements and operational definitions only on the basis of published data and experience derived from those registries that have used Utstein-style reporting. Attention was focused on decreasing the complexity of the existing templates and addressing logistical difficulties in collecting specific core and supplementary (ie, essential and desirable) data elements recommended by previous Utstein consensus conferences. Inconsistencies in terminology between in-hospital and out-of-hospital Utstein templates were also addressed. The task force produced a reporting tool for essential data that can be used for both quality improvement (registries) and research reports and that should be applicable to both adults and children. The revised and simplified template includes practical and succinct operational definitions. It is anticipated that the revised template will enable better and more accurate completion of all reports of cardiac arrest and resuscitation attempts. Problems with data definition, collection, linkage, confidentiality, management, and registry implementation are acknowledged and potential solutions offered. Uniform collection and tracking of registry data should enable better continuous quality improvement within every hospital, emergency medical services system, and community.

Abstract
This paper reports the results of the first of the two systems developed by JUST, a collaborative project supported by the European Union under the Information Society Technologies (IST) Programme. The most innovative content of the project has been the design and development of a complementary training course for non-professional health emergency operators, which supports the traditional learning phase, and which purports to improve the retention capability of the trainees. This was achieved with the use of advanced information technology techniques, which provide adequate support and can help to overcome the present weaknesses of the existing training mechanisms.

Abstract
Malignant hyperthermia (MH) is a pharmacogenetic disorder of skeletal muscle that is triggered in genetically predisposed individuals by common anesthetics and muscle relaxants. The ryanodine receptor (RYR1) is mutated in a number of MH pedigrees, some members of which also have central core disease (CCD), an inherited myopathy closely associated with MH. Mutation screening of 6 kb of the RYR1 gene has identified four adjacent novel mutations, C6487T, G6488A, G6502A, and C6617T, which result in the amino acid alterations Arg2163Cys, Arg2163His, Val2168Met, and Thr2206Met, respectively. Collectively, these mutations account for 11% of MH cases and identify the gene segment 6400-6700 as a mutation hot spot. Correlation analysis of the in vitro contracture-test data available for pedigrees bearing these and other RYR1 mutations showed an exceptionally good correlation between caffeine threshold and tension values, whereas no correlation was observed between halothane threshold and tension values. This finding has important ramifications for assignment of the MH-susceptible phenotype, in genotyping studies, and indicates that assessment of recombinant individuals on the basis of caffeine response is justified, whereas assessment on the basis of halothane response may be problematic. Interestingly, the data suggest a link between the caffeine threshold and tension values and the MH/CCD phenotype.

Abstract
Our aim was to develop an exercise protocol using 31P-magnetic resonance spectroscopy (31P-MRS), which can discriminate between malignant hyperthermia-susceptible (MHS) individuals and controls. MRS spectra of the forearm muscles were recorded at rest, during and after a standardized exercise protocol in 10 MHS patients and compared with spectra obtained in 10 controls. There was no difference in resting intracellular pH (pHi) or PCr/(Pi+PCr) ratio between the groups (PCr = phosphocreatine, Pi = inorganic phosphorus). At the end of the exercise and during the initial recovery phase, the pHi and PCr/(Pi+PCr) ratio were significantly lower in the MHS group ([pHi: 6.37 (0.07) for MHS vs 6.70 (0.05) for controls, P < 0.005; PCr/(Pi+PCr): 0.784 (0.017) for MHS vs 0.954 (0.020) for controls, P < 0.0005]). For PCr/(Pi+PCr), complete separation between the two groups was observed during the initial recovery phase. The mean recovery time of PCr/(Pi+PCr) was 0.57 min for the control group and 1.28 min for the MHS group. The slower recovery of PCr/(Pi+PCr) is likely to be caused by a combination of several factors, including the lower pHi in MHS subjects at the start of recovery (inhibiting ATP production) and excessive sarcoplasmic calcium overload (causing continued enzyme activation and ATP consumption). Our exercise protocol can be a valuable adjunct to discriminate between MHS and non susceptible subjects.

Abstract
Malignant hyperthermia (MH) is an autosomal dominant disorder which is potentially lethal in susceptible individuals on exposure to commonly used inhalational anaesthetics and depolarising muscle relaxants. Crises reflect the consequences of disturbed skeletal muscle calcium homeostasis. Susceptibility was first localised to chromosome 19q13.1 and the skeletal muscle ryanodine receptor, RYR1 (the calcium release channel of the sarcoplasmic reticulum). Defects in this gene have been identified which cosegregate with the MHS phenotype and evidence as to their potential causal roles has accumulated. MH has, however, been shown to be genetically heterogeneous, additional loci on chromosomes 3q, 17q and 7q being proposed. Pedigrees remain in Europe where linkage status is still unclear. In a collaborative search of the human genome conducted with three pedigrees whose disease status was classified according to the European IVCT protocol we have evidence to suggest that at least two further loci exist for MH susceptibility. One of these locates to chromosome 1q, the site of a candidate gene, CACNL1A3, encoding the alpha-subunit of the dihydropyridine receptor. The second region resides on chromosome 5p to where no known candidate has been mapped to date. The third family exhibited inconclusive results which suggests the existence of at least one other locus. This study adds to the evidence for considerable genetic heterogeneity in MH and will provide a route to further our understanding of the molecular pathology of the condition.

Abstract
Malignant hyperthermia (MH) is a potentially lethal pharmacogenetic disease for which MH susceptibility (MHS) is transmitted as an autosomal dominant trait. A potentially life-threatening MH crisis is triggered by exposure to commonly used inhalational anesthetics and depolarizing muscle relaxants. The first malignant hyperthermia susceptibility locus (MHS1) was identified on human chromosome 19q13.1, and evidence has been obtained that defects in the gene for the calcium-release channel of skeletal muscle sarcoplasmic reticulum (ryanodine receptor; RYR1) can cause some forms of MH. However, MH has been shown to be genetically heterogeneous, and additional loci on chromosomes 17q and 7q have been suggested. In a collaborative search of the human genome with polymorphic microsatellite markers, we now found linkage of the MHS phenotype, as assessed by the European in vitro contracture test protocol, to markers defining a 1-cM interval on chromosome 3q13.1. A maximum multipoint lod score of 3.22 was obtained in a single German pedigree with classical MH, and none of the other pedigrees investigated in this study showed linkage to this region. Linkage to both MHS1/RYR1 and putative loci on chromosome 17q and 7q were excluded. This study supports the view that considerable genetic heterogeneity exists in MH.

Abstract
Malignant hyperthermia (MH) is a potentially fatal autosomal dominant disorder of skeletal muscle and is triggered in susceptible people by all commonly used inhalational anaesthetics. To date, the ryanodine receptor gene (RYR1) has been shown to be mutated in a small number of malignant hyperthermia susceptible (MHS) cases. To determine if a common RYR1 mutation exists that might account for a significant number of MHS cases, we have investigated the RYR1 gene in unrelated patients for the presence of new mutations by the single-stranded conformation polymorphism method and have identified a novel Gly341Arg mutation which accounts for approximately 10% of Caucasian MHS cases. The implications of this common mutation in MHS diagnosis and heterogeneity studies are discussed.

Abstract
Malignant hyperthermia susceptibility (MHS) is an autosomal dominant disorder of skeletal muscle which manifests as a life-threatening hypermetabolic crisis triggered by commonly-used inhalation anaesthetics and depolarizing muscle relaxants. Defects in the ryanodine receptor (RYR1) protein have been proposed to underly MHS, but significant genetic heterogeneity in MHS has recently been demonstrated. In order to investigate the potential roles played by other skeletal muscle calcium channels in MHS, we isolated cosmids containing the gene encoding the beta 1-subunit of skeletal muscle L-type voltage-dependent calcium channel (CACNLB1). We identified a new, highly polymorphic dinucleotide repeat motif close to this gene, and linkage analysis placed the marker proximal to the HOX2B locus, previously localized to chromosome segment 17q21-q22. We recently identified a novel marker within the gamma-subunit locus (CACNLG) at band 17q24, and since both markers are within the 17q11.2-q24 region reported to contain the MHS2 locus, we tested them for linkage in MHS families whose disease trait has been shown not to co-segregate with markers for the RYR1 region on chromosome 19q13.1. Our results exclude CACNLB1 and CACNLG as candidate genes for MHS2, and do not support the reported chromosome 17q localization for the MHS2 locus in our families.
