Abstract Background Refractory out of hospital cardiac arrest (OHCA) is associated with extremely poor outcomes. However, in selected patients extracorporeal cardiopulmonary resuscitation (eCPR) may be an effective rescue therapy, allowing time treat reversible causes. The primary goal was to estimate the potential future caseload of eCPR at historically 'low-volume' extracorporeal membrane oxygenation (ECMO) centres. Methods A 3-year observational study of OHCA presenting to the Emergency Department (ED of an urban referral centre without historical protocolised use of eCPR. Demographics and standard Utstein outcomes are reported. Further, an a priori analysis of each case for potential eCPR eligibility was conducted. A current eCPR selection criteria (from the 2-CHEER study) was used to determine eligibly. Results In the study window 248 eligible cardiac arrest cases were included in the OHCA registry. 30-day survival was 23.4% (n=58). The mean age of survivors was 55.4 years. 17 (6.8%) cases were deemed true refractory arrests and fulfilled the 2-CHEER eligibility criteria. The majority of these cases presented within “office hours” and no case obtained a return of spontaneous circulation standard advanced life support. Conclusions In this contemporary OHCA registry a significant number of refractory cases were deemed potential eCPR candidates reflecting a need for future interdisciplinary work to support delivery of this therapy.

Objective Most western emergency medical services provide advanced life support in out-of-hospital cardiac arrest aiming for a return of spontaneous circulation at the scene. Little attention is given to prehospital time management in the case of out-of-hospital cardiac arrest with regard to early coronary angiography or to the start of extracorporeal cardiopulmonary resuscitation treatment within 60 minutes after out-of-hospital cardiac arrest onset. We investigated the emergency medical services on-scene time, defined as emergency medical services arrival at the scene until departure to the hospital, and its association with 30-day survival with favourable neurological outcome after out-of-hospital cardiac arrest. Methods All patients of over 18 years of age with non-traumatic, non-emergency medical services witnessed out-of-hospital cardiac arrest between July 2013 and August 2015 from the Vienna Cardiac Arrest Registry were included in this retrospective observational study. Results Out of 2149 out-of-hospital cardiac arrest patients, a total of 1687 (79%) patients were eligible for analyses. These patients were stratified into groups according to the on-scene time (<35 minutes, 35–45 minutes, 45–60 minutes, >60 minutes). Within short on-scene time groups, out-of-hospital cardiac arrest occurred more often in public and bystander cardiopulmonary resuscitation was more common (both P<0.001). Patients who did not achieve return of spontaneous circulation at the scene showed higher rates of 30-day survival with favourable neurological outcome with an on-scene time of less than 35 minutes (adjusted odds ratio 5.00, 95% confidence interval 1.39–17.96). Conclusion An emergency medical services on-scene time of less than 35 minutes was associated with higher rates of survival and favourable outcomes. It seems to be reasonable to develop time optimised advance life support protocols to minimise the on-scene time in view of further treatments such as early coronary angiography as part of post-resuscitation care or extracorporeal cardiopulmonary resuscitation in refractory out-of-hospital cardiac arrest.

Catecholamines are entrenched in the management of shock states. A paradigm shift has pervaded the critical care arena in recent years acknowledging their propensity to cause harm and fuel a ‘death-spiral’. We present the case of a 21-year-old male following a witnessed out-of-hospital cardiac arrest who received high-quality cardiopulmonary resuscitation and standard advanced life support for refractory ventricular fibrillation until return of spontaneous circulation after 70 min. Early post-admission echocardiography revealed severe diffuse sub-basal left ventricular hypertrophy with dynamic mid-cavity obstruction and akinetic apical pouching. Within this context, a decatecholaminised strategy comprising a beta-blocker was used to augment the left ventricular end-diastolic volume and attain cardiovascular stability.

Mode Of Death

Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) might be a lifesaving therapy for patients with cardiac arrest and no return of spontaneous circulation during advanced life support. However, even with ECPR, mortality of these severely sick patients is high. Little is known on the exact mode of death in these patients. Methods: Retrospective registry analysis of all consecutive patients undergoing ECPR between May 2011 and May 2020 at a single center. Mode of death was judged by two researchers. Results: A total of 274 ECPR cases were included (age 60.0 years, 47.1% shockable initial rhythm, median time-to-extracorporeal membrane oxygenation (ECMO) 53.8min, hospital survival 25.9%). The 71 survivors had shorter time-to-ECMO durations (46.0 ± 27.9 vs. 56.6 ± 28.8min, p < 0.01), lower initial lactate levels (7.9 ± 4.5 vs. 11.6 ± 8.4 mg/dL, p < 0.01), higher PREDICT-6h (41.7 ± 17.0% vs. 25.3 ± 19.0%, p < 0.01), and SAVE (0.4 ± 4.8 vs. −0.8 ± 4.4, p < 0.01) scores. Most common mode of death in 203 deceased patients was therapy resistant shock in 105/203 (51.7%) and anoxic brain injury in 69/203 (34.0%). Comparing patients deceased with shock to those with cerebral damage, patients with shock were significantly older (63.2 ± 11.5 vs. 54.3 ± 16.5 years, p < 0.01), more frequently resuscitated in-hospital (64.4% vs. 29.9%, p < 0.01) and had shorter time-to-ECMO durations (52.3 ± 26.8 vs. 69.3 ± 29.1min p < 0.01). Conclusions: Most patients after ECPR decease due to refractory shock. Older patients with in-hospital cardiac arrest might be prone to development of refractory shock. Only a minority die from cerebral damage. Research should focus on preventing post-CPR shock and treating the shock in these patients.

Background: There is an urgent need to identify strategies which improve outcomes for out-of-hospital cardiac arrest (OHCA). Determining the optimal access route to deliver medications during resuscitation from OHCA may be one such strategy. Methods: Using data from the Continuous Chest compression trial between 2011 and 2016, we examined rates of sustained return of spontaneous circulation (ROSC) i.e. ROSC on ER arrival, survival to discharge and survival with favorable neurological function (modified Rankin scale ≤3) among patients with attempted IV and IO access. Results: Among 19,731 patients with available access information, IO or IV access was attempted in 3,068 (15.5%) and 16,663 (84.5%) patients, respectively and was successful in 2,975 (97%) and 15,485 (92%) of these patients. Overall, patients with attempted IO access were younger, more likely female, received less bystander CPR, had lower proportions of shockable and witnessed arrests, marginally faster times to access and to epinephrine administration, and less frequently received therapeutic hypothermia and coronary angiography as compared with patients with IV access ( Table ) . Unadjusted rates of sustained ROSC, discharge survival and survival with favorable neurological function were significantly lower in patients with attempted IO access ( Table) . After adjustment for age, sex, initial rhythm, bystander CPR, public location, witnessed status, EMS response time and trial cluster, attempted IO access was associated with lower sustained ROSC rates (OR 0.79, 95% CI 0.71-0.89, p<0.001) but not with discharge survival (OR 0.88, 95% CI 0.71-1.08, p=0.21) or survival with favorable neurological function (OR 0.86, 95% CI 0.67-1.1, p=0.26). Conclusions: Among patients with OHCA, intraosseous access was attempted in 1 in 7 OHCA patients and associated with worse ROSC rates but no difference in survival. Further studies are necessary to elucidate the optimal access route among OHCA patients.

Background: In-hospital cardiac arrest is a major cause of death in European countries, and survival of patients remains low ranging from 20% to 25%. Aims: The purpose of this study was to assess healthcare professionals’ knowledge on cardiopulmonary resuscitation among university hospitals in 12 European countries and correlate it with the return of spontaneous circulation rates of their patients after in-hospital cardiac arrest. Methods and results: A total of 570 healthcare professionals from cardiology, anaesthesiology and intensive care medicine departments of European university hospitals in Italy, Poland, Hungary, Belgium, Spain, Slovakia, Germany, Finland, The Netherlands, Switzerland, France and Greece completed a questionnaire. The questionnaire consisted of 12 questions based on epidemiology data and cardiopulmonary resuscitation training and 26 multiple choice questions on cardiopulmonary resuscitation knowledge. Hospitals in Switzerland scored highest on basic life support ( P=0.005) while Belgium hospitals scored highest on advanced life support ( P<0.001) and total score in cardiopulmonary resuscitation knowledge ( P=0.01). The Swiss hospitals scored highest in cardiopulmonary resuscitation training ( P<0.001). Correlation between cardiopulmonary resuscitation knowledge and return of spontaneous circulation rates of patients with in-hospital cardiac arrest demonstrated that each additional correct answer on the advanced life support score results in a further increase in return of spontaneous circulation rates (odds ratio 3.94; 95% confidence interval 2.78 to 5.57; P<0.001). Conclusion: Differences in knowledge about resuscitation and course attendance were found between university hospitals in 12 European countries. Education in cardiopulmonary resuscitation is considered to be vital for patients’ return of spontaneous circulation rates after in-hospital cardiac arrest. A higher level of knowledge in advanced life support results in higher return of spontaneous circulation rates.

Paramedics can provide advanced life support (ALS) for patients with out-of-hospital cardiac arrest (OHCA). However, the impact of emergency medical technician (EMT) configuration on their outcomes remains debated. A three-year cohort study consisted of non-traumatic OHCA adults transported by ALS teams was retrospectively conducted in Tainan City using an Utstein-style population database. The EMT-paramedic (EMT-P) ratio was defined as the EMT-P proportion out of all on-scene EMTs. Among the 1357 eligible cases, the median (interquartile range) number of on-scene EMTs and the EMT-P ratio were 2 (2–2) persons and 50% (50–100%), respectively. The multivariate analysis identified five independent predictors of sustained return of spontaneous circulation (ROSC): younger adults, witnessed cardiac arrest, prehospital ROSC, prehospital defibrillation, and comorbid diabetes mellitus. After adjustment, every 10% increase in the EMT-P ratio was on average associated with an 8% increased chance (adjusted odds ratio [aOR], 1.08; p < 0.01) of sustained ROSC and a 12% increase change (aOR, 1.12; p = 0.048) of favorable neurologic status at discharge. However, increased number of on-scene EMTs was not linked to better outcomes. For nontraumatic OHCA adults, an increase in the on-scene EMT-P ratio resulted in a higher proportion of improved patient outcomes.

Introduction: The patient outcome after OHCA is poor. Return to spontaneous circulation (ROSC) dramatically decreases with the duration of CPR. It has been proposed to implement extracorporeal membrane oxygenation in order to assist CPR (ECPR) in OHCA. Objective: To investigate the effects of ECPR in emergency (ED) for OHCA. Methods: A prospective 4-year observational database collected from a community-wide OHCA registry in an urban EMS was studied. The EMS ambulance staffs were capable with advanced airway, intravenous (iv) fluid skills, basic and advanced life support and AED techniques. Outcomes included 2-hour and 24-hour sustained ROSC, survival (SD) and cerebral performance category scale (CPC) at discharge. OHCA receiving ECPR were included and their pre-hospital (pre-H) and hospital (H) characteristics and outcomes were evaluated by regression analysis. Results: In the 4 years among a total of 7,220 OHCA resuscitated in ED, ECPR was used 88 times (90% male, median age 54 [IQR 44-63]), 90% non-traumatic, 58.6% arrest witnessed, 50.6% with bystander CPR, up to 72.6% initial AED rhythm showing shockable, 54% with LMA (laryngeal mask airway), 5.7% with endotracheal intubation, 18.2% with pre-H iv epinephrine, and 12.5% of them received therapeutic hypothermia. Pre-H time intervals (min:sec, median [IQR]) were 04:38 [03:30-06:08] for response, 13:00 [10:05-16:00] for scene, and 03:08 [02:09-05:00] for transport. Only 10.2% of cases presented pre-H ROSC and 9.1% got ROSC upon H arrival. Outcomes were 88.6% for 2-hr ROSC, 69.3% for 24-hr ROSC, 39.1% for SD, and 21% for good CPC 1or2 respectively. Patients with CPC 1or2 tended to be younger (median age 46.8 vs. 55.9, p=0.04) and less with LMA (29.4 vs. 61.9%, p=0.02). Conclusions: ECPR can lead to survival and good neurological outcome in selected OHCA regardless of positive ROSC at pre-H or upon H arrival after EMS resuscitation. Elder age and pre-H LMA may be adverse to neurological outcome for OHCA with ECPR.

AbstractIn-hospital cardiac arrest (IHCA) is associated with poor outcomes. There are currently no standards for cardiac arrest teams in terms of member composition and task allocation. Here we aimed to compare two different cardiac arrest team concepts to cover IHCA management in terms of survival and neurological outcomes. This prospective study enrolled 412 patients with IHCA from general medical wards. From May 2014 to April 2016, 228 patients were directly transferred to the intensive care unit (ICU) for ongoing resuscitation. In the ICU, resuscitation was extended to advanced cardiac life support (ACLS) (Load-and-Go [LaG] group). By May 2016, a dedicated cardiac arrest team provided by the ICU provided ACLS in the ward. After return of spontaneous circulation (ROSC), the patients (n = 184) were transferred to the ICU (Stay-and-Treat [SaT] group). Overall, baseline characteristics, aetiologies, and characteristics of cardiac arrest were similar between groups. The time to endotracheal intubation was longer in the LaG group than in the SaT group (6 [5, 8] min versus 4 [2, 5] min, p = 0.001). In the LaG group, 96% of the patients were transferred to the ICU regardless of ROSC achievement. In the SaT group, 83% of patients were transferred to the ICU (p = 0.001). Survival to discharge did not differ between the LaG (33%) and the SaT (35%) groups (p = 0.758). Ultimately, 22% of patients in the LaG group versus 21% in the SaT group were discharged with good neurological outcomes (p = 0.857). In conclusion, we demonstrated that the cardiac arrest team concepts for the management of IHCA did not differ in terms of survival and neurological outcomes. However, a dedicated (intensive care) cardiac arrest team could take some load off the ICU.

INTRODUCTION: With an incidence of ~45patients with out-of hospital cardiac arrest (OHCA) /100.000 inhabitants per year and thus over 700 cases annually, but a survival rate as low as 10%, OHCA remains still a challenge the chain of survival. Recently ventilation has gained less importance for BLS and thus the question arises, if this attitude was mirrored during ALS measures provided by ambulance crews. Therefore our analysis assessed the quality of ventilation during out of hospital cardiac arrests. METHODS: Over a period of 9 months, from August 1st 2013 until April 30th 2014, all patients suffering from an OHCA, aged 18 years and above and treated by the emergency medical service crews in Vienna, Austria were included in this study. A collective of 701 consecutive cases have been analyzed using the ECG- and impedance data recorded by the defibrillators used. On the basis of this data, the abidance of the quality standards of ventilation was examined using the current guidelines of the European Resuscitation Council of 2010 as gold standard. After the evaluation of each case, the responding EMS-teams were informed about the quality of the resuscitation via a feedback form. RESULTS: Endotracheal intubation was accomplished in 338 patients (47%). Ventilation was performed in accordance to the ERC guidelines in 49% (CI: 46-52) of total recorded ventilation minutes. Patients who had restoration of spontaneous circulation (ROSC) (n=135) after being intubated were ventilated with 9 (CI: 9-11; variance: 11) ventilations per minute. In patients not achieving ROSC (n=203) 10 (CI: 9-11; variance: 25) ventilations per minute were administered. Patients that were ventilated with a supraglottic airway device or a bag valve and mask received 6(SD±4) ventilations per minute. CONCLUSION: The high ventilation rate standard deviations within the compliance to guidelines suggest that there are numerous cases in which ventilation standards are not met. Therefore further analysis will be necessary to find out, what influence this might have on outcome and if it will be necessary to put more emphasis in upcoming discussions on the quality of ventilation at least during advanced life support.
