Introduction The probability of surviving a cardiac arrest remains low. International resuscitation guidelines state that extracorporeal cardiopulmonary resuscitation (ECPR) may have a role in selected patients suffering refractory cardiac arrest. Identifying these patients is challenging. This project systematically reviewed the evidence comparing the outcomes of ECPR over conventional-CPR (CCPR), before examining resuscitation-specific parameters to assess which patients might benefit from ECPR. Method Literature searches of studies comparing ECPR to CCPR and the clinical parameters of survivors of ECPR were performed. The primary outcome examined was survival at hospital discharge or 30 days. A secondary analysis examined the resuscitation parameters that may be associated with survival in patients who receive ECPR (no-flow and low-flow intervals, bystander-CPR, initial shockable cardiac rhythm, and witnessed cardiac arrest). Results Seventeen of 948 examined studies were included. ECPR demonstrated improved survival (OR 0.40 (0.27–0.60)) and a better neurological outcome (OR 0.10 (0.04–0.27)) over CCPR during literature review and meta-analysis. Characteristics that were associated with improved survival in patients receiving ECPR included an initial shockable rhythm and a shorter low-flow time. Shorter no-flow, the presence of bystander-CPR and witnessed arrests were not characteristics that were associated with improved survival following meta-analysis, although the quality of input data was low. All data were non-randomised, and hence the potential for bias is high. Conclusion ECPR is a sophisticated treatment option which may improve outcomes in a selected patient population in refractory cardiac arrest. Further comparative research is needed clarify the role of this potential resuscitative therapy.

AbstractObjectiveExtracorporeal cardiopulmonary resuscitation (ECPR), while resource-intensive, may improve outcomes in selected patients with refractory out-of-hospital cardiac arrest (OHCA). We sought to identify patients who fulfilled a set of ECPR criteria in order to estimate: (1) the proportion of patients with refractory cardiac arrest who may have benefited from ECPR; and (2) the outcomes achieved with conventional resuscitation.MethodsWe performed a secondary analysis from a 52-month prospective registry of consecutive adult non-traumatic OHCA cases from a single urban Canadian health region serving one million patients. We developed a hypothetical ECPR-eligible cohort including adult patients <60 years of age with a witnessed OHCA, and either bystander CPR or EMS arrival within five minutes. The primary outcome was the proportion of ECPR-eligible patients who had refractory cardiac arrest, defined as termination of resuscitation pre-hospital or in the ED. The secondary outcome was the proportion of EPCR-eligible patients who survived to hospital discharge.ResultsOf 1,644 EMS-treated OHCA, 168 (10.2%) fulfilled our ECPR criteria. Overall, 54/1644 (3.3%; 95% CI 2.4%-4.1%) who were ECPR-eligible had refractory cardiac arrest. Of ECPR-eligible patients, 114/168 (68%, 95% CI 61%-75%) survived to hospital admission, and 70/168 (42%; 95% CI 34-49%) survived to hospital discharge.ConclusionIn our region, approximately 10% of EMS-treated cases of OHCA fulfilled our ECPR criteria, and approximately one-third of these (an average of 12 patients per year) were refractory to conventional resuscitation. The integration of an ECPR program into an existing high-performing system of care may have a small but clinically important effect on patient outcomes.

Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) can treat cardiac arrest refractory to conventional therapy. Many institutions are interested in developing their own ECPR program. However, there are challenges in logistics and implementation. Hypothesis: Development of an ECPR team and identification of UPMC Presbyterian as a receiving center will increase recognition of potential ECPR candidates. Methods: We developed an infrastructure of Emergency Medical Services (EMS), Medic Command, and an in-hospital ECPR team. We identified inclusion criteria for patients with an out of hospital cardiac arrest (OHCA) likely to have a reversible arrest etiology and developed them into a simple checklist. These criteria were: witnessed arrest with bystander CPR, shockable rhythm, and ages 18 to 60. We trained local EMS crews to screen patients and review the checklist with a Command Physician prior to transport to our hospital. Results: From October 2015 to March 31 st 2018, there were 1165 dispatches for OHCA, of which 664 (57%) were treated and transported to the hospital and 120 to our institution. Of these, five patients underwent ECPR. Of the remaining cases, 64 (53%) had nonshockable rhythms, 48 (40%) were unwitnessed arrests, 50 (42%) were over age 60 and the remaining 20 (17%) had no documented reasons for exclusion. Prehospital CPR duration was 26 [IQR 25-40] min. Four patients (80%) underwent mechanical CPR with LUCAS device. Time from arrest to arrive on scene was 5 [IQR 4-6] min and time call MD command was 13 [IQR 7-21] min. Time to transport was 20 [IQR 19-21] min. Time from arrest to initiation of ECMO was 63 [IQR 59-69] min. Conclusions: ECPR is a relatively infrequent occurrence. Implementation challenges include prompt identification of patients with reversible OHCA causes, preferential transport to an ECPR capable facility and changing the focus of EMS in these select patients from a “stay and play” to a “load and go” mentality.

Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) is a promising treatment for refractory out-of-hospital cardiac arrest (OHCA). Most studies evaluating the effectiveness of ECPR include patients with an initial shockable rhythm. However, the effectiveness of ECPR for patients with an initial non-shockable rhythm remains unknown. This retrospective single-center study aimed to evaluate the effectiveness of ECPR for patients with an initial non-shockable rhythm, with reference to the outcomes of OHCA patients with an initial shockable rhythm. Methods Adult OHCA patients treated with ECPR at our center during 2011–2018 were included in the study. Patients were classified into the initial shockable rhythm group and the non-shockable rhythm group. The primary outcome was the cerebral performance category (CPC) scale score at hospital discharge. A CPC score of 1 or 2 was defined as a good outcome. Results In total, 186 patients were eligible. Among them, 124 had an initial shockable rhythm and 62 had an initial non-shockable rhythm. Among all patients, 158 (85%) were male, with a median age of 59 (interquartile range [IQR], 48–65) years, and the median low flow time was 41 (IQR, 33–48) min. Collapse was witnessed in 169 (91%) patients, and 36 (19%) achieved return of spontaneous circulation (ROSC) transiently. Proportion of female patients, presence of bystander cardiopulmonary resuscitation, and collapse after the arrival of emergency medical service personnel were significantly higher in the non-shockable rhythm group. The rate of good outcomes at hospital discharge was not significantly different between the shockable and non-shockable groups (19% vs. 16%, p=0.69). Initial shockable rhythm was not significantly associated with good outcome after controlling for potential confounders (adjusted odds ratio 1.58, 95% confidence interval: 0.66–3.81, p=0.31). In the non-shockable group, patients with good outcomes had a higher rate of transient ROSC, and pulmonary embolism was the leading etiology. Conclusions The outcomes of patients with an initial non-shockable rhythm are comparable with those having an initial shockable rhythm. OHCA patients with an initial non-shockable rhythm could be candidates for ECPR, if they are presumed to have reversible etiology and potential for good neurological recovery.

ABSTRACTObjectivesExtracorporeal cardiopulmonary resuscitation in refractory cardiac arrest (ECPR) is an emerging resuscitative therapy that has shown promising results for selected patients who may not otherwise survive. We sought to identify the characteristics of cardiac arrest patients presenting to our institution to begin assessing the feasibility of an ECPR program.MethodsThis retrospective health records review included patients aged 18–75 years old presenting to our academic teaching hospital campuses with refractory nontraumatic out-of-hospital or in-emergency department (ED) cardiac arrest over a 2-year period. Based on a scoping review of the literature, both “liberal” and “restrictive” ECPR criteria were defined and applied to our cohort.ResultsA total of 179 patients met inclusion criteria. Median age was 60 years, and patients were predominantly male (72.6%). The initial rhythm was ventricular tachycardia/ventricular fibrillation in 49.2%. The majority of arrests were witnessed (69.3%), with immediate bystander CPR performed on 53.1% and an additional 12% receiving CPR within 10 minutes of collapse. Median prehospital time was 40 minutes (interquartile range, 31–53.3). Two-thirds of patients (65.9%) were identified as having a reversible cause of arrest and favorable premorbid status was identified in nearly three quarters (74.3%). Our two sets of ECPR inclusion criteria revealed that 33 and 5 patients (liberal and restrictive criteria, respectively), would have been candidates for ECPR.ConclusionAt our institution, we estimate between 6% and 40% of ED refractory cardiac arrest patients would be candidates for ECPR. These findings suggest that the implementation of an ECPR program should be explored.

Aim: To compare survival rates in patients with refractory cardiac arrest treated with extracorporeal cardiopulmonary resuscitation (ECPR) before and after implementation of an action card.The primary outcome was survival to discharge, and secondary outcomes were low-flow time and rate of cerebral complications. Methods: Retrospective evaluation of 37 patients treated with ECPR for refractory cardiac arrest. Information was obtained through medical records. Patients were categorized into two groups - before (BA) and after (AA) introduction of an action card. The card entailed inclusion and exclusion criteria used to evaluate the benefit of ECPR for any individual patient. Results: There were no statistically significant differences in baseline characteristics between the groups.After the introduction of the action card, survival to discharge increased from 6.7 % to 18.2 % suggesting a trend toward improved survival, despite this finding being statistically insignificant (p = 0.629).Low-flow time was reduced from 100 (12-195) minutes to 66 (30-195) minutes and the upper extreme was reduced from 195 to 153 minutes, but this was not statistically significant (p = 0.334).Cerebral factors contributed to significantly fewer deaths in AA compared with BA (p = 0.0022). Conclusion: There was no statistically significant improvement in survival rates nor a reduction in low-flow time after the implementation of an action card for the use of ECPR in patients with refractory CA. However, cerebral causes factored in fewer deaths and several patients survived despite meeting potential exclusion criteria outlined in local and international guidelines.

Abstract Background The 2015 cardiopulmonary resuscitation (CPR) guidelines have stressed that high-quality CPR improves survival from cardiac arrest (CA). In particular, the guidelines recommended that it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min in adult CA patients. However, it is unknown whether the 2015 guidelines contributed to favorable neurological outcome in adult CA patients. The present study aimed to clarify the effects of the 2015 guidelines in adult CA patients, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital CA (OHCA). Methods From the data of this registry between 2011 and 2016, we included adult witnessed OHCA patients due to cardiac etiology, who had non-shockable rhythm as an initial rhythm. We excluded patients who received prehospital care in 2015 because it was difficult to distinguish prehospital care based on either 2010 CPR guidelines or 2015 CPR guidelines. We also excluded patients who received bystander CPR by citizens because we cannot assess the quality of bystander CPR in this registry. Study patients were divided into five groups based on different years (figure). The endpoint was the favorable neurological outcome at 30 days after OHCA. Potential confounding factors based on biological plausibility and previous studies were included in the multivariable logistic regression analysis. These variables included the age, sex (male, female), advanced airway or not, the administration of adrenaline or not, the administration of saline or not, instructed by dispatcher or not, and time interval from call EMS to scene. Results The figure showed favorable neurological outcomes at 30 days. In the multivariate analysis, the adjusted odds ratio for 30-day favorable neurological outcome in OHCA patients in 2016 as compared to in 2011 was 1.32 (95% CI: 1.04–1.68, p=0.022). On the other hands, there were no significant differences from 2011 to 2014. Conclusion In the OHCA patients with non-shockable rhythm, the 2015 guidelines were superior to the 2010 guidelines, in terms of neurological benefits.

Refractory Cardiac Arrest

We report the case of a 54-year-old man who suffered from refractory cardiac arrest secondary to acute myocardial infarction. As veno-arterial extracorporeal membrane oxygenation was unavailable, mechanical chest compression was performed and an Impella device was used that immediately delivered at 3.2 l/min flow to reach the optimal mean arterial pressure. Within 1 min, return of spontaneous circulation was achieved and a 40% left ventricular ejection fraction was measured on echography. Then, the right coronary artery could be revascularised. Despite 62 min low flow, the patient was discharged home on day 19 without neurological sequelae. During refractory cardiac arrest, the European Resuscitation Guidelines indicate that veno-arterial extracorporeal membrane oxygenation should be considered as rescue therapy. Other mechanical circulatory supports such as an Impella device (left ventricular assist device propelling blood in the ascending aorta) can be a promising treatment in select patients; however, insufficient data in humans are available.
