AbstractSynergistic effects of fibrinolytic and additional antithrombotic treatment during cardiopulmonary resuscitation in out-of-hospital cardiac arrest of assumed cardiac origin were evaluated retrospectively. Data were drawn from electronic files of the physician-staffed Emergency Medical Services Tyrol. During a 22-month observation period 53 adult patients were treated with tenecteplase (mean 7641 IU), 19 (32.1%) of whom received additional antithrombotic treatment with heparin (4000–5000 IU) and acetylsalicylic acid (250–500 mg). Lasting return of spontaneous circulation occurred in four of 34 patients who received fibrinolytic treatment only and in seven of 19 patients with additional antithrombotic treatment (p = 0.037). Four of five patients who were discharged from hospital had received additional antithrombotic treatment during CPR and were in appropriate neurological status (CPC 1). Considering the small sample size in this retrospective study, the argument may be still be made that fibrinolytic and adjunctive antithrombotic treatment during cardiopulmonary resuscitation in out-of-hospital cardiac arrest of assumed cardiac origin may increase the chances for survival.

High-quality cardiopulmonary resuscitation (CPR) is a key element in out-of-hospital cardiac arrest (OHCA) resuscitation. Mechanical CPR devices have been developed to provide uninterrupted and high-quality CPR. Although human studies have shown controversial results in favor of mechanical CPR devices, their application in pre-hospital settings continues to increase. There remains scant data on the pre-hospital use of mechanical CPR devices in Asia. Therefore, we conducted a retrospective cohort study between September 2018 and August 2020 in an urban city of Taiwan to analyze the effects of mechanical CPR devices on the outcomes of OHCA; the primary outcome was attainment of return of spontaneous circulation (ROSC). Of 552 patients with OHCA, 279 received mechanical CPR and 273 received manual CPR, before being transferred to the hospital. After multivariate adjustment for the influencing factors, mechanical CPR was independently associated with achievement of any ROSC (OR = 1.871; 95%CI:1.195–2.930) and sustained (≥24 h) ROSC (OR = 2.353; 95%CI:1.427–3.879). Subgroup analyses demonstrated that mechanical CPR is beneficial in shorter emergency medical service response time (≤4 min), witnessed cardiac arrest, and non-shockable cardiac rhythm. These findings support the importance of early EMS activation and high-quality CPR in OHCA resuscitation.

Abstract Background The influence of past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events toward willingness to “pay it forward” by helping the next cardiac arrest victim was explored. Methods Using a validated questionnaire, 6248 participants were asked to rate their willingness to perform bystander chest compression with mouth-to-mouth ventilation and chest compression-only CPR. Their past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events were also recorded. Results Kruskal-Wallis test with post hoc Dunn’s pairwise comparisons showed that the following were significantly more willing to perform CPR with mouth-to-mouth ventilation: familial experience of “nonfatal cardiac events” (mean rank = 447) vs “out-of-hospital cardiac arrest with no CPR” (mean rank = 177), U = 35442.5, z = −2.055, p = 0.04; “in-hospital cardiac arrest and successful CPR” (mean rank = 2955.79) vs “none of these experiences” (mean rank = 2468.38), U = 111903, z = −2.60, p = 0.01; and “in-hospital cardiac arrest with successful CPR” (mean rank = 133.45) vs “out-of-hospital arrest with no CPR” (mean rank = 112.36), U = 4135.5, z = −2.06, p = 0.04. For compression-only CPR, Kruskal-Wallis test with multiple runs of Mann-Whitney U tests showed that “nonfatal cardiac events” group was statistically higher than the group with “none of these experiences” (mean rank = 3061.43 vs 2859.91), U = 1194658, z = −2.588, p = 0.01. The groups of “in-hospital cardiac arrest with successful CPR” and “in-hospital cardiac arrest with transient return of spontaneous circulation” were the most willing groups to perform compression-only CPR. Conclusion Prior familial experiences of receiving CPR and medical help, particularly among those with successful outcomes in a hospital setting, seem to increase the willingness to perform bystander CPR.

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.

Abstract Background: Incidence of in-hospital cardiac arrest is reported to be 0.8 to 4.6 per 1,000 patient admissions. Patient survival to hospital discharge with favourable functional and neurological status is around 21%. The Bern University Hospital is a tertiary medical centre in Switzerland with a cardiac arrest team from the Department of Anaesthesiology and Pain Medicine that is available 24 h per day, 7 days per week. Due to lack of central documentation of cardiac arrest team interventions, the incidence, outcomes and survival rates of cardiac arrests are unknown. The aim was thus to record all cardiac arrest team interventions over 1 year, and to analyse the outcome and survival rates of adult patients after in-hospital cardiac arrests.Methods: We conducted a prospective single-centre observational study that recorded all adult in-hospital cardiac arrest team interventions over 1 year, using an Utstein-style case report form. The primary outcome was 30-day survival after in-hospital cardiac arrest. Secondary outcomes were return of spontaneous circulation, neurological status (after return of spontaneous circulation, after 24 h, after 30 days and 1 year), according to the Glasgow Outcomes Scale, and functional status at 30 days and 1 year, according to the Short-form-12 Health Survey.Results: The cardiac arrest team had 146 interventions over the study year, which included 60 non-life-threatening alarms (41.1%). The remaining 86 (58.9%) acute life-threatening situations included 68 (79.1%) as patients with cardiac arrest. The mean age of these cardiac arrest patients was 68 ±13 years, with a male predominance (51/68; 75.0%). Return of spontaneous circulation was recorded in 49 patients (72.1%). Over one-third of the cardiac arrest patients (27/68) were alive after 30 days with favourable neurological outcome. The patients who survived to 1 year after the event showed favourable neurological and functional status. Conclusions: The in-hospital cardiac arrest incidence on a large tertiary Swiss university hospital was 1.56 per 1,000 patient admissions. After a cardiac arrest, about a third of the patients survived to 1 year with favourable neurological and functional status. Early recognition and high-quality cardiopulmonary resuscitation provided by a well-organised team is crucial for patient survival.Trial Registration: The trial was registered in clinicaltrials.gov (NCT02746640).

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest. Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions. Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes. Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.

A 58-year-old man is brought by the ambulance to the emergency department (ED) of a tertiary care centre following an out-of-hospital cardiac arrest. Paramedics were called by the patient's wife after he had collapsed. She immediately initiated cardiopulmonary resuscitation (CPR). Prior to his collapse, he had been complaining of chest pain. His initial rhythm in the field was ventricular fibrillation, and he received defibrillation. An automated CPR device was applied prior to transport. En route, return of spontaneous circulation is achieved. An electrocardiogram shows ST-segment elevation in the anterior leads. Just prior to arrival, the patient suffers recurrent cardiac arrest with two further rounds of unsuccessful defibrillation in the ED. At this point, a decision is made to proceed with extracorporeal cardiopulmonary resuscitation (ECPR), prior to transport for cardiac catheterization.

Introduction: Multiple citizen responder (CR) programs worldwide which dispatch laypersons to out-of-hospital cardiac arrest (OHCA) to perform cardiopulmonary resuscitation (CPR) and use of automated external defibrillators (AEDs) were affected by the COVID-19 outbreak in 2020, but little is known about how the pandemic affected CR activation and initiation of bystander CPR and defibrillation. In Denmark, the CR program continued to run during lockdown but with the recommendation to perform chest-compression-only CPR in contrast to standard CPR including ventilations. We hypothesized that bystander interventions as CPR and AED usage decreased during the first COVID-19 lockdown in two regions of Denmark in the spring of 2020. Methods: All OHCAs from January 1, 2020 to June 30, 2020 with CR activation from the Danish Cardiac Arrest Registry and the National Citizen Responder database. Bystander CPR, AED usage, and CRs’ alarm acceptance rate during the national lockdown from March 11, 2020 to April 20, 2020 were compared with the non-lockdown period from January 1, 2020 to March 10, 2020 and from April 21 to June 30, 2020. Results: A total of 6,120 CRs were alerted in 443 (23/100.000 inhabitants) cases of presumed OHCA of which 256 (58%) were confirmed cardiac arrests. Bystander CPR remained equally high in the lockdown period compared with non-lockdown period (99% vs. 92%, p=0.07). Likewise, there was no change in bystander defibrillation (9% vs. 14%, p=0.4). There was a slight increase in the number of CRs who accepted an alarm (7 per alarm, IQR 4) during lockdown compared with non-lockdown period (6 per alarm, IQR 4), p=0.0001. The proportion of patients achieving return of spontaneous circulation at hospital arrival was also unchanged (lockdown 23% vs non-lockdown 23%, p=1.0) (Table 1). Conclusion: Bystander initiated resuscitation rates did not change during the first COVID-19 lockdown in Denmark for OHCAs where CRs were activated through a smartphone app.

Background: Out-of-hospital cardiac arrest (OHCA) remains a leading cause of death in the US, affecting over 400,000 annually. Although outcomes have improved, rates of return of spontaneous circulation (ROSC) and survival are lower from OHCA than from in-hospital cardiac arrest. Clinical emergencies, including OHCA, in outpatient clinical settings are often first attended by rapid response teams (RRT), but the causes and outcomes from OHCA in these environments has not been characterized. An understanding of this population is critical both for RRT quality improvement and resource allocation. Objectives: We aimed to describe OHCA that occurred in outpatient clinical environments. We hypothesized that OHCA in ambulatory settings would be uncommon and would be concentrated in a limited number of higher-risk outpatient areas. Methods: Retrospective analysis of all RRT calls for non-hospitalized adult outpatients occurring between 2012- 2020 at the Hospital of the University of Pennsylvania. Results: There were 7336 RRT calls;25 were for OHCA. Information was available for 24 of these. Mean age was 64 +/- 16.7 y, and 38% were female. Initial rhythm was pulseless electrical activity in 79%, ventricular fibrillation in 13%, asystole in 4%, and was not recorded in 4%. CPR was initiated in all cases prior to the arrival of the RRT. ROSC was obtained in 84%, extracorporeal membrane oxygenation (ECMO) was initiated in 8%, and 8% did not survive. ROSC was obtained within 5 min in 58% of cases. Of those that attained ROSC, 75% survived to discharge, 80% with good neurological status (CPC 1-2). Most events (54%) were judged to be iatrogenic. Of these, 54% were due to anaphylaxis, 15% were during cardiac stress testing, and 31% were peri-procedural. The most common causes of anaphylaxis were chemotherapeutics and radiographic contrast agents. Conclusions: OHCA events are uncommon in the outpatient clinical setting and are frequently iatrogenic. These events are associated with high rates of ROSC and neurologically intact survival. Iatrogenic OHCA occurred during a limited number of clinical settings, including outpatient procedural, , infusion, and stress test locations.. This finding suggests the need to focus resuscitation training in these specific environments.
