Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) is a rapidly evolving technology for clinical use in patients with refractory cardiogenic arrest. Out-of-hospital cardiac arrest (OHCA) is a common cause of unexpected death and has a low survival rate. There is increasing evidence that suggests better outcomes for (OHCA) patients, including improved neurological outcomes and survival rates, who are started on extracorporeal corporeal membrane oxygenation (ECMO) versus traditional resuscitation methods. Methods: We conducted a retrospective chart review of 200 out-of-hospital cardiac arrest patients presenting to Regina emergency departments from January 1, 2017 to March 31, 2019. Eligibility for ECPR was assessed using different clinical criteria from different ECPR programs (University of British Columbia, University of Michigan, and a hypothetical “Regina” criteria created for this study). Outcomes of the eligible patients were compared using descriptive statistics with SPSS version 22. Results: Between four different criteria, 15%, 9.5%, 7.5%, and 3.5% of patients were respectively eligible to receive ECPR. Of patients who met eligibility for all four criteria, 80% were male, the average age was 61 years old, the average Cerebral Performance score was 4.46, and 83% died in hospital. There was a low survival rate of eligible patients, with rates of 16%, 17%, 20%, and 28% in each group. The survival rate for all patients was 21% and the average CPC score was 4.35. Conclusion: The significant percentage of patients were eligible for ECPR upon presentation to Regina Emergency Departments. Patients who were eligible had low survival rates and poor neurological outcomes, suggesting that ECPR could prove to be a valuable clinical tool that could improve patient outcomes in Saskatchewan. There were considerable differences in patient eligibility percentages based on different criterion. Differences in inclusion/exclusion criteria, modifying the expected annual number of ECPR eligible OHCA patients, could provide valuable information on required resources and planning for implementation of an ECPR program in a smaller centre, such as Regina.

Background: In Japan, extracorporeal cardiopulmonary resuscitation (ECPR) became popular for cardiac arrest patients who resist conventional advanced life supports. Regardless of many clinical experiences, there has been no previous systematic literature review. Methods: Case series, reports and proceedings of scientific meeting about ECPR for out-of-hospital cardiac arrest written in Japanese between January 1, 1983 and July 31, 2007 were collected with Japana Centra Revuo Medicina (medical publication database in Japan) and review by experts. The outcome and characteristics of the patients were investigated, and the influence of publication bias of the case series study was also examined by the Funnel Plot method. Results: There were 951 out-of-hospital cardiac arrest patients who received ECPR in 92 reports (including 59 case series and 33 case reports) during the period. The average of age was 38.1 (4 – 88) years old and 76.1% was male. Three hundreds and eighty-one cases (40.1%) were arrests of cardiac etiology, and 212 were non-cardiac (22.3%). The cause of arrest was not described in other 37.6%. Excluding reports for only one case, weighted survival rate at discharge of 792 cases those were clearly described the outcome was 39.5±10.0%. When the relationship between the number of cases and the survival rate at discharge in each 59 case series study was shown in figure by the Funnel Plot method, the plotted data presented the reverse-funnel type that centered on the average of survival rate of all. Conclusions: The influence of publication bias of previous reports in Japan was relatively low. ECPR can greatly contribute to improve the outcome of out-of hospital cardiac arrests.

Hospital Cardiac Arrest

IntroductionExtracorporeal cardiopulmonary resuscitation (eCPR) is increasingly applied in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) patients. Treatment results are promising, but the efficacy and safety of the procedure are still unclear. Currently, there are no recommended target perfusion parameters during eCPR, the lack of which could result in inadequate (re)perfusion. We aim to perform a scoping review to explore the current literature addressing target perfusion parameters, target values, corresponding survival rates and neurologic outcomes in OHCA and IHCA patients treated with eCPR.Methods and analysisTo identify relevant research, we will conduct searches in the electronic databases MEDLINE, EMBASE, Social Science Citation Index, Social Science Citation Index Expanded and the Cochrane library. We will also check references of relevant articles and perform a cited reference research (forward citation tracking).Two independent reviewers will screen titles and abstracts, check full texts for eligibility and perform data extraction. We will resolve dissent by consensus, moderated by a third reviewer. We will include observational and controlled studies addressing target perfusion parameters and outcomes such as survival rates and neurologic findings in OHCA and IHCA patients treated with eCPR. Data extraction tables will be set up, including study and patients’ characteristics, aim of study, details on eCPR including target perfusion parameters and reported outcomes. We will summarise the data using tables and figures (ie, bubble plot) to present the research landscape and to describe potential clusters and/or gaps.Ethics and disseminationAn ethical approval is not needed. We intend to publish the scoping review in a peer-reviewed journal and present results on a scientific meeting.

BackgroundSeveral Chinese cities have implemented dispatcher-assisted cardiopulmonary resuscitation (DA-CPR), although out-of-hospital cardiac arrest (OHCA) survival rates remain low. We aimed to assess the process compliance, barriers and outcomes of OHCA in one of the earliest implemented (DA-CPR) programmes in China.MethodsWe retrospectively reviewed OHCA emergency dispatch records of Suzhou emergency medical service from 2014 to 2015 and included adult OHCA victims (>18 years) with a bystander-witnessed atraumatic OHCA that was subsequently confirmed by on-site emergency physician. The circumstances and DA-CPR process related to the OHCA event were analysed. Dispatch audio records were reviewed to identify potential barriers to implementation during the DA-CPR process.ResultsOf the 151 OHCA victims, none survived. The median time from patient collapse to call for emergency services and that from call to provision of cardiopulmonary resuscitation instructions was 30 (IQR 20–60) min and 115 (IQR 90–153) s, respectively. Only 110 (80.3%) bystanders/rescuers followed the dispatcher instructions; of these, 51 (46.3%) undertook persistent chest compressions. Major barriers to following the DA-CPR instructions were present in 104 (68.9%) cases, including caller disconnection of the call, distraught mood or refusal to carry out either compressions or ventilations.ConclusionsThe OHCA survival rate and the DA-CPR process were far from optimal. The zero survival rate is disproportionally low compared with survival statistics in high-income countries. The prolonged delay in calling the emergency services negated and rendered futile any DA-CPR efforts. Thus, efforts targeted at developing public awareness of OHCA, calling for help and competency in DA-CPR should be increased.

Objectives: Out-of-hospital cardiac arrest (OHCA) is associated with excessively high mortality rates. Recent studies suggest benefits from extracorporeal cardiopulmonary resuscitation (ECPR) performed in selected patients. We sought to present the first results from our interdisciplinary ECPR program with a particular focus on early outcomes and potential risk factors associated with in-hospital mortality. Methods: Between January 2016 and December 2019, 44 patients who underwent ECPR selected according to our institutional ECPR protocol were retrospectively analyzed regarding pre-hospital, in-hospital, and early outcome parameters. Patients were divided into survivors (S) and non-survivors (NS). Statistical analysis of risk factors regarding in-hospital mortality of the patient cohort analyzed was performed. Results: The mean age of the population was 53 ± 12 years, with most patients being male ( n = 40). The leading cause of cardiac arrest (CA) was myocardial infarction ( n = 24, 55%). The median hospital stay was 1 (1;13) day. Twenty-three percent of patients ( n = 10) were discharged from hospital including eight patients (18%) with CPC 1–2. Survivors showed a trend toward shorter pre-hospital CPR duration (60 (59;60) min (S) vs 60 (55;90) min (NS), p = 0.07). Conclusion: Establishing ECPR programs in large population areas offers the option to improve survival rates for OHCA patients. Stringent compliance of institutional criteria (mainly age, witnessed arrest, and time of pre-hospital resuscitation) and providing ECPR to strictly selected patients seems to be a vital factor for such programs’ success. Pre-clinical settings and therapeutic measures must be adjusted in this regard to improve outcomes for this highly demanding patient cohort.

Abstract Objectives To evaluate the number of out-of-hospital cardiac arrest (OHCA) patients eligible for extracorporeal cardiopulmonary resuscitation (ECPR) in Saskatchewan and their clinical outcomes, including survival and neurological outcomes at discharge. ECPR eligibility was assessed, using clinical criteria from the University of British Columbia (UBC), University of Michigan (UM), University of California (UC) and a restrictive ECPR criteria. Results We performed a retrospective cohort study of 200 OHCA patients (August 1, 2017-May 31, 2019) in Regina, Saskatchewan. Sixty-one (30%) were female, the median age was 64 years (interquartile range [IQR], 52–78), the median CPR duration was 30 minutes (IQR 12–47), and 20% survived to discharge. Two (1%) patients received ECPR but did not meet any ECPR criteria. Nineteen (10%), thirty (15%), twenty-two (11%), and seven (4%) patients were ECPR-eligible, using the UBC, UM, UC, and restrictive criteria. However, none of these patients had received ECPR. Only two (11%), two (7%), two (9%), and one (14%) of these patient(s) survived to discharge, respectively. Neurological outcomes were unfavourable among all ECPR-eligible patients. Future study at our centre will be necessary on how to implement ECPR program to further improve these outcomes.

Background: The aim of this study was to analyze the effect of extracorporeal cardiopulmonary resuscitation on survival and neurological outcomes in in-hospital cardiac arrest patients. Methods: Between January 2018 and December 2020, a total of 22 patients (17 males, 5 females; mean age: 52.8±9.0 years; range, 32 to 70 years) treated with extracorporeal cardiopulmonary resuscitation using veno-arterial extracorporeal membrane oxygenation support for in-hospital cardiac arrest after acute coronary syndrome were retrospectively analyzed. The patients were divided into two groups as those weaned (n=13) and non-weaned (n=9) from the veno-arterial extracorporeal membrane oxygenation. Demographic data of the patients, heart rhythms at the beginning of conventional cardiopulmonary resuscitation, the angiographic and interventional results, survival and neurological outcomes of the patients before and after extracorporeal cardiopulmonary resuscitation were recorded. Results: There was no significant difference between the groups in terms of comorbidity and baseline laboratory test values. The underlying rhythm was ventricular fibrillation in 92% of the patients in the weaned group and there was no cardiac rhythm in 67% of the patients in the non-weaned group (p=0.125). The recovery in the mean left ventricular ejection fraction was significantly evident in the weaned group (36.5±12.7% vs. 21.1±7.4%, respectively; p=0.004). The overall wean rate from veno-arterial extracorporeal membrane oxygenation was 59.1%; however, the discharge rate from hospital of survivors without any neurological sequelae was 36.4%. Conclusion: In-hospital cardiac arrest is a critical emergency situation requiring instantly life-saving interventions through conventional cardiopulmonary resuscitation. If it fails, extracorporeal cardiopulmonary resuscitation should be initiated, regardless the underlying etiology or rhythm disturbances. An effective conventional cardiopulmonary resuscitation is mandatory to prevent brain and body hypoperfusion.

Introduction: Previous studies have shown an association between hyperoxemia and mortality in out-of-hospital cardiac arrest (OHCA) patients after cardiopulmonary resuscitation (CPR); however, the evidence is lacking in patients receiving extracorporeal CPR (ECPR). Hypothesis: To test the hypothesis that hyperoxemia is associated with poor neurological outcome in patients treated by ECPR. Methods: The Japanese Association for Acute Medicine - OHCA (JAAM-OHCA) Registry is a multicenter, prospective, observational registry including 34,754 OHCA patients between 2014 and 2017. Patients who had been resuscitated and survived 24 hours after OHCA and had a PaO 2 levels above 60 mmHg were included. Eligible patients were divided into 2 groups by each 2 definition according to the PaO 2 levels measured from arterial blood gas analysis 24-h after the ECPR, (1) High-level of PaO 2 (H-PaO 2 , n=242) as PaO 2 ≥ 157 mmHg (median) and control (n=211) as 60 < PaO 2 < 157 mmHg, (2) hyperoxemia (HO, n=80) as PaO 2 ≥ 300 mmHg and control (n=373) as 60 < PaO 2 < 300 mmHg. The primary and secondary outcomes were the favorable neurological outcome, defined as Cerebral Performance Categories (CPC) Scale 1-2, and survival at 30 days after OHCA, respectively. Results: Out of 34,754 patients with OHCA, 453 patients with ECPR were included. The number of CPC 1-2 was significantly lower in the H-PaO 2 and HO group compared with each control group (H-PaO 2 : 17.4% vs. 33.2%; Odds ratio [OR] 0.42; 95% confidence interval [CI] 0.27-0.66; P<0.0001, HO: 8.8% vs. 28.2%; OR 0.24; 95% CI 0.11-0.55; P<0.001). The 30-day survival was lower in these high oxygen groups (H-PaO 2 : 39.3% vs. 57.4%; OR 0.48; 95% CI 0.33-0.70; P<0.0001, HO: 25.0% vs. 52.6%; OR 0.30; 95% CI 0.17-0.52; P<0.0001). After adjusting for potential confounders, the H-PaO 2 and HO were associated with unfavorable neurological outcomes (adjusted OR, H-PaO 2 ; 2.71; 95% CI 1.16-6.30; P=0.021, HO; 5.76; 95% CI 1.30-25.4; P=0.021). The H-PaO 2 and HO were also associated with poor 30-day survival (adjusted OR, H-PaO 2 ; 2.28; 95% CI 1.13-4.60; P=0.021, HO; 3.75; 95% CI 1.28-11.0; P=0.016). Conclusions: Hyperoxemia was associated with worse neurological outcomes in OHCA patients with ECPR.
