RESUMO
BACKGROUND: The effect of mechanical CPR is diversely described in the literature. Different mechanical CPR devices are available. The corpuls cpr is a new generation of piston-driven devices and was launched in 2015. The COMPRESS-trial analyzes quality of chest compression and CPR-related injuries in cases of mechanical CPR by the corpuls cpr and manual CPR. METHODS: This article describes the design and study protocol of the COMPRESS-trial. This observational multi-center study includes all patients who suffered an out-of-hospital cardiac arrest (OHCA) where CPR is attempted in four German emergency medical systems (EMS) between January 2020 and December 2022. EMS treatment, in-hospital-treatment and outcome are anonymously reported to the German Resuscitation Registry (GRR). This information is linked with data from the defibrillator, the feedback system and the mechanical CPR device for a complete dataset. Primary endpoint is chest compression quality (complete release, compression rate, compression depth, chest compression fraction, CPR-related injuries). Secondary endpoint is survival (return of spontaneous circulation (ROSC), admission to hospital and survival to hospital discharge). The trial is sponsored by GS Elektromedizinische Geräte G. Stemple GmbH. DISCUSSION: This observational multi-center study will contribute to the evaluation of mechanical chest compression devices and to the efficacy and safety of the corpuls cpr. TRIAL REGISTRATION: DRKS, DRKS-ID DRKS00020819 . Registered 31 July 2020.

AIM: The aim of this study was to develop a score to predict the outcome for patients brought to hospital following out-of-hospital cardiac arrest (OHCA). METHODS: All patients recorded in the German Resuscitation Registry (GRR) who suffered OHCA 2010-2017, who had ROSC or ongoing CPR at hospital admission were included. The study population was divided into development (2010-2016: 7985) and validation dataset (2017: 1806). Binary logistic regression analysis was used to derive the score. The probability of hospital discharge with good neurological outcome was defined as 1/(1â¯+â¯e-X), where X is the weighted sum of independent variables. RESULTS: The following variables were found to have a significant positive (+) or negative (-) impact: age 61-70 years (-0·5), 71-80 (-0·9), 81-90 (-1·3) and >â¯=â¯91 (-2·3); initial PEA (-0·9) and asystole (-1·4); presumable trauma (-1·1); mechanical CPR (-0·3); application of adrenalin >â¯0â¯-â¯<â¯2â¯mg (-1·1), 2â¯-â¯<4â¯mg (-1·6), 4â¯-â¯<â¯6â¯mg (-2·1), 6â¯-â¯<â¯8â¯mg (-2·5) and >â¯=â¯8â¯mg (-2·8); pre emergency status without previous disease (+0·5) or minor disease (+0·2); location at nursing home (-0·6), working place/school (+0·7), doctor's office (+0·7) and public place (+0·3); application of amiodarone (+0·4); hospital admission with ongoing CPR (-1·9) or normotension (+0·4); witnessed arrest (+0·6); time from collapse until start CPR 2â¯-â¯<â¯10â¯min (-0·3) and >â¯=â¯10â¯min (-0·5); duration of CPR <5â¯min (+0·6). The AUC in the development dataset was 0·88 (95% CI 0·87-0·89) and in the validation dataset 0·88 (95% CI 0·86-0·90). CONCLUSION: The CaRdiac Arrest Survival Score (CRASS) represents a tool for calculating the probability of survival with good neurological function for patients brought to hospital following OHCA.

Trauma-related deaths are not only a relevant medical problem but also a socioeconomic one. The care of a polytraumatized patient is one of the less commonly occurring missions in the rescue and emergency medical services. The aim of this article is to compare the similarities and differences between different course concepts and guidelines in the treatment of trauma-related cardiac arrests (TCA) and to filter out the main focus of each concept. Because of the various approaches in the treatment of polytraumatized patients, there are decisive differences between trauma-related cardiac arrests and cardiac arrests from other causes.

OBJECTIVE: There is international variation in the rates of bystander cardiopulmonary resuscitation (CPR). 'Bystander CPR' is defined in the Utstein definitions, however, differences in interpretation may contribute to the variation reported. The aim of this cross-sectional survey was to understand how the term 'bystander CPR' is interpreted in Emergency Medical Service (EMS) across Europe, and to contribute to a better definition of 'bystander' for future reference. METHODS: During analysis of the EuReCa ONE study, uncertainty about the definition of a 'bystander' emerged. Sixty scenarios were developed, addressing the interpretation of 'bystander CPR'. An electronic version of the survey was sent to 27 EuReCa National Coordinators, who distributed it to EMS representatives in their countries. Results were descriptively analysed. RESULTS: 362 questionnaires were received from 23 countries. In scenarios where a layperson arrived on scene by chance and provided CPR, up to 95% of the participants agreed that 'bystander CPR' had been performed. In scenarios that included community response systems, firefighters and/or police personnel, the percentage of agreement that 'bystander CPR' had been performed ranged widely from 16% to 91%. Even in scenarios that explicitly matched examples provided in the Utstein template there was disagreement on the definition. CONCLUSION: In this survey, the interpretation of 'bystander CPR' varied, particularly when community response systems including laypersons, firefighters, and/or police personnel were involved. It is suggested that the definition of 'bystander CPR' should be revised to reflect changes in treatment of OHCA, and that CPR before arrival of EMS is more accurately described.

BACKGROUND: Airway management during resuscitation is pivotal for treating hypoxia and inducing reoxygenation. This German Resuscitation Registry (GRR) analysis investigated the influence of the type of airway used in patients treated with manual chest compression (mCC) and automated chest compression devices (ACCD) after out-of-hospital cardiac arrest (OHCA). METHODS: Out of 42,977 patients (1 January 2010-30 June 2016) information on outcome, airway management and method of chest compressions were available for 27,544 patients. Hospital admission under cardiopulmonary resuscitation (CPR), hospital admission with return of spontaneous circulation (ROSC), hospital discharge and discharge with cerebral performance categories 1 and 2 (CPC 1,2) were used to compare outcome in patients treated with mCC vs. ACCD, and classified by endotracheal intubation (ETI), initial supraglottic airway device (SAD) changed into ETI, and only SAD use. RESULTS: Outcomes for hospital admission under ongoing CPR, hospital admission with ROSC, hospital discharge and neurologically intact survival (CPC 1,2) for mCC (84.8%) vs. ACCD (15.2%) groups were: 8.4/38.6%, 39.2/27.2%, 10.6/6.8%, 7.9/4.7% (p < 0.001), respectively. Only mCC with SAD/ETI for ever ROSC (OR 1.466, 95% CI: 1.353-1.588, p < 0.001) and mCC group with SAD/ETI for hospital admission with ROSC showed better outcomes (odds ratio [OR] 1.277, 95% confidence interval [CI]: 1.179-1.384, p < 0.001) in comparison to mCC treated with ETI. Compared to mCC/ETI, all other groups were associated with a decrease in neurologically intact survival. CONCLUSION: Better outcomes were found for mCC in comparison to ACCD and ETI showed better outcomes in comparison to SAD only. This observational registry study raised the hypothesis that SAD only should be avoided or SAD should be changed into ETI, independent of whether mCC or ACCD is used.

BACKGROUND: Approximately 18 million patients are treated in German hospitals annually. On the basis of internationally published data the number of in-hospital cardiac arrests can be estimated as 54,000 per year. A structured treatment of in-hospital resuscitation according to the current scientific evidence is essential. AIM: In-hospital resuscitation shows some special characteristics in comparison to resuscitation in emergency services, which are highlighted in this article. MATERIAL AND METHODS: This article is based on the international guidelines for cardiopulmonary resuscitation (CPR) first published in 1992 by the European Resuscitation Council (ERC) and the American Heart Association (AHA) as well as the amendments (current version 2010). Some current studies are also presented, which could not be taken into consideration for the guidelines from 2010. RESULTS: High quality chest compressions with as few interruptions as possible are of utmost importance. Patients with cardiac rhythms which can be defibrillated should be defibrillated within less than 2 min after the collapse. There is no evidence that equipping hospitals with automated external defibrillators is an advantage for survival after in-hospital cardiac arrest. Endotracheal intubation represents the gold standard of airway management during CPR. During in-hospital resuscitation experienced anesthesiologists are mostly involved; however, the use of supraglottic airway devices may help to minimize interruptions in chest compressions especially before the medical emergency team arrives at the scene. Feedback devices may improve the quality of manual chest compressions; however, most devices overestimate the compression depth if the patient is resuscitated when lying in bed. There is no evidence that mechanical chest compression devices improve the outcome after cardiac arrest. Mild therapeutic hypothermia is still recommended for neuroprotection after successful in-hospital resuscitation. CONCLUSION: The prevention of cardiac arrest is of special importance. Uniform and low threshold criteria for alarming the medical emergency team have to be defined to be able to identify and treat critically ill patients in time before cardiac arrest occurs.

Sudden death due to cardiac arrest represents one of the greatest challenges facing modern medicine, not only because of the massive number of cases involved but also because of its tremendous social and economic impact. For many years, the magic figure of 1 per 1000 inhabitants per year was generally accepted as an estimate of the annual incidence of sudden death in the industrialized world, with a survival rate of 6 %. This estimate was based on large numbers of published reports of local, regional, national and multinational experience in the management of cardiac arrest. Measuring the global incidence of cardiac arrest is challenging as many different definitions of patient populations are used. Randomized controlled trials (RCT) provide insights into the value of specific treatments or treatment strategies in a well-defined section of a population. Registries do not compete with clinical studies, but represent a useful supplement to them. Surveys and registries provide insights into the ways in which scientific findings and guidelines are being implemented in clinical practice. However, as with clinical studies, comprehensive preparations are needed in order to establish a registry. This is all the more decisive because not all of the questions that may arise are known at the time when the registry is established. The German resuscitation registry started in May 2007 and currently more than 230 paramedic services and hospitals take part. More than 45,000 cases of out-of-hospital cardiac arrest and in-hospital cardiac arrest are included. With this background the German resuscitation registry is one of the largest databases in emergency medicine in Germany. After 5 years of running the preclinical care dataset was revised in 2012. Data variables that reflect current or new treatment were added to the registry. The postresuscitation basic care and telephone cardiopulmonary resuscitation (CPR) datasets were developed in 2012 and 2013 as well. The German resuscitation registry is an instrument of quality management and a research network. The registry documents the course in patients who have undergone resuscitation at the time points of first aid, further management and long-term outcome and it can therefore provide a complete presentation of the procedures carried out and the quality of the outcomes. In addition, important scientific questions can be answered from the database. For example, a score for benchmarking the outcome quality after out-of-hospital resuscitation, known as the return of spontaneous circulation (ROSC) after cardiac arrest (RACA) score, has been developed. The registry is available for all emergency medical services (EMS) and hospitals in Germany and other German-speaking countries.

Amniotic fluid embolism is a rare peripartum complication with the sudden onset of haemodynamic instability, respiratory failure and coagulopathy during labour or soon after delivery. A 31-year-old woman with amniotic fluid embolism was treated with vasopressors, inotropes, intravenous fluid, tranexamic acid and ventilatory support. Assessment of respiratory impairment was made using conventional chest X-ray, computed tomography and electrical impedance tomography. The potential for electrical impedance tomography to improve monitoring and guide respiratory therapy is explored.
