Abstract: BACKGROUND: Trauma has previously been shown to influence interleukin (IL)-6 and IL-10 levels, but the association of injury severity and mortality with IL-6 and IL-10 responses in the early phase of accidental trauma remains to be investigated. We wished to describe serum levels of IL-6 and IL-10 in the first 24 h after trauma and to assess the relationship with severity of injury and mortality. METHODS: Prospective, descriptive cohort study in a Level 1 trauma centre, Copenhagen, Denmark. We included 265 consecutive adult trauma patients admitted directly from the accident scene during an 18-month period. Serum levels of IL-6 and IL-10 were measured upon arrival and at 6, 12, and 24 h after admittance using an enzyme-linked immunosorbent assay. Correlation analysis was used to assess the relationship between Injury Severity Score (ISS) and levels of IL-6 and IL-10. Analysis of variance was used to describe the IL-6 and IL-10 concentrations in relation to 30-day mortality in a mixed-effect model repeated measures analysis. RESULTS: Mortality was 10.9% (29/265) at 30 days. A significant increase of both IL-6 and IL-10 concentrations was found over time, and a significant correlation was found between ISS and the levels of both IL-6 and IL-10 at all sampling points. Serum concentrations of IL-6 and IL-10 were significantly higher in patients not surviving 30 days (P<0.0001). CONCLUSION: The early systemic inflammatory response measured as IL-6 and IL-10 in serum is correlated with injury severity and 30-day mortality following trauma.
Abstract: CONTEXT: The impact of clinical experience on learning outcome from a resuscitation course has not been systematically investigated. AIM: To determine whether half a year of clinical experience before participation in an Advanced Life Support (ALS) course increases the immediate learning outcome and retention of learning. MATERIALS AND METHODS: This was a prospective single blinded randomised controlled study of the learning outcome from a standard ALS course on a volunteer sample of the entire cohort of newly graduated doctors from Copenhagen University. The outcome measurement was ALS-competence assessed using a validated composite test including assessment of skills and knowledge. INTERVENTION: The intervention was half a year of clinical work before an ALS course. The intervention group received the course after a half-year of clinical experience. The control group participated in an ALS course immediately following graduation. RESULTS: Invitation to participate was accepted by 154/240 (64%) graduates and 117/154 (76%) completed the study. There was no difference between the intervention and control groups with regard to the immediate learning outcome. The intervention group had significantly higher retention of learning compared to the control group, intervention group mean 82% (CI 80-83), control group mean 78% (CI 76-80), P=0.002. The magnitude of this difference was medium (effect size=0.57). CONCLUSIONS: Half a year of clinical experience, before participation in an ALS course had a small but statistically significant impact on the retention of learning, but not on the immediate learning outcome.
Abstract: BACKGROUND: Training of healthcare staff in cardiopulmonary resuscitation (CPR) is time-consuming and costly. It has been suggested to replace instructor facilitated (IF) training with an automated voice advisory manikin (VAM), which increases skill level by continuous verbal feedback during individual training. AIMS: To compare a VAM (ResusciAnne CPR skills station, Laerdal Medical A/S, Norway) with IF training in CPR using a bag-valve-mask (BVM) in terms of skills retention after 3 months. METHODS: Forty-three second year medical students were included and CPR performance (ERC Guidelines for Resuscitation 2005) was assessed in a 2 min test before randomisation to either IF training in groups of 8 or individual VAM training. Immediately after training and after 3 months, CPR performance was assessed in identical 2 min tests. Laerdal PC Skill Reporting System 2.0 was used to collect data. To quantify CPR performance a scoring system based on the Cardiff test was used. Groups were compared with a Mann Whitney rank sum test. RESULTS: There was no statistically significant difference between the two groups when considering change in overall CPR performance score from before training to 3 months after training (P=0.12). However, the IF group performed significantly better than the VAM group in the total score, both immediately after (P=0.0008) and 3 months after training (P=0.02). This difference was primarily related to the BVM skills. CONCLUSION: Skill retention in CPR using a bag-valve-mask was better after 3 months when training with an instructor than with an automated voice advisory manikin.
Abstract: OBJECTIVES: To establish a uniform framework describing the system and organisation of emergency medical response centres and the process of emergency medical dispatching (EMD) when reporting results from studies in emergency medicine and prehospital care. DESIGN AND RESULTS: In September 2005 a task force of 22 experts from 12 countries met in Stavanger; Norway at the Utstein Abbey to review data and establish a common terminology for medical dispatch centres including core and optional data to be used for health monitoring, benchmarking and future research.
Abstract: INTRODUCTION: In 2005, new international evidence-based guidelines for cardiopulmonary resuscitation (CPR) were published by the International Liaison Committee on Resuscitation (ILCOR). The aim of these new guidelines is to improve the quality of care and, thereby, the outcome from cardiac arrest. This necessitates that the guidelines are known and implemented in clinical practice. The purpose of this investigation is to elucidate the extent of implementation of Guidelines 2005 (G2005) among doctors on Cardiac Arrest Teams (CAT) one year after the publication. In addition, the date of implementation is examined among medical emergency services and major providers of basic life support (BLS) courses. MATERIAL AND METHODS: A telephone enquiry about CPR among CAT doctors on-duty. Ambulance services and BLS-course providers are contacted by e-mail. RESULTS: Approximately 70% of the doctors were able to answer simple and essential topics on CPR, e.g. compression/ventilation ratio and the number of shocks in a sequence in accordance with G2005. The ambulance service, Falck A/S, implemented G2005 during 2007, while the other ambulance services implemented G2005 within six months after publication. The majority of BLS-course providers implemented the guidelines one year after their publication. CONCLUSION: One year after the publication of G2005, there is limited knowledge of the guidelines among doctors on duty. The study does not give any explanation for the lack of implementation. The barriers to implementation should be clarified, and future guidelines should be accompanied by an active strategy for implementation.
Abstract: The new ERC guidelines on resuscitation emphasize the importance of quality CPR. BLS should be started as early as possible. Lay rescuers should not check for a pulse, they should call for help and start chest compressions immediately. Compression depth should be 4-5 cm at a rate of 100 compressions per minute. Chest compressions and ventilation should be performed in a ratio of 30:2. Lay rescuers should continue until professional help arrives. Lay rescuers may use the same procedure for children as recommended for adults. Professionals should, however, initiate CPR in children with 5 ventilations followed by a compression-ventilation ratio of 15:2. Automatic External Defibrillation should be used as early as possible.
Abstract: International and European Resuscitation Council (ERC) Guidelines for Resuscitation 2005 implicate major changes in resuscitation, including new universal treatment algorithms. This brief summary of Guidelines 2005 for advanced resuscitation of adult cardiac arrest victims is based upon the ERC Guidelines which also constitute the Danish Resuscitation Council's recommendations.
