Background: Rates of neurologically intact survival after cardiac arrest remain abysmal. Neuro-prognostication intra-arrest is challenging, with few real-time factors that can be used to determine patient prognosis. During the implementation of a new cardiopulmonary resuscitation (CPR) protocol in a large urban pre-hospital system, first responders prospectively recorded the presence of signs of perfusion during CPR. Hypothesis: Positive signs of perfusion would be a predictor of a good neurologic outcome in this observational study, as defined by Cerebral Performance Category (CPC) Score of 1 or 2. Methods: Basic life support first responders (n = 420) and paramedics (n = 207) underwent training including didactic and hands-on sessions to learn the new protocol, which included active compression-decompression CPR with an impedance threshold device. In addition to patient demographics and circumstances of cardiac arrest, signs of perfusion during CPR were prospectively recorded and included improved color, pulse during CPR, gasping, and movement during CPR. Chart review was performed to determine CPC score at discharge. Data were analyzed using descriptive statistics and calculation of unadjusted odds ratios. Results: The new protocol began May 1, 2017. Cases from May 2017-November 2017 (n= 102) were reviewed, with complete data available for 96 patients (94%). The median age was 56 (range 25-97), 54/91 (59%) male, 43/102 (42%) witnessed, 31/90 (34%) shockable rhythm, and 51/102 (50%) receiving bystander CPR. Improved color during CPR was seen in 23/102 (23%), pulse during CPR in 17/102 (17%), gasping in 18/102 (18%), and movement during CPR in 5/102 (5%). Any sign of perfusion during CPR was seen in 47/102 (46%), and 13/96 (13.5%) had a CPC score of 1 or 2 at discharge. The unadjusted OR for any sign of perfusion during CPR for a CPC score of 1 or 2 was 26 (95% CI 3 - 213) and for any sign of perfusion during CPR for ROSC was 9 (95% CI 3 - 24). Conclusions: Positive signs of perfusion during CPR noted by first responders strongly predicted ROSC and neurologically intact survival in this small sample. This suggests the importance of prospectively recording signs of perfusion during resuscitation, and communicating these observations during transfer of care.

AbstractPrecise criteria for extracorporeal cardiopulmonary resuscitation (ECPR) are still lacking in patients with out-of-hospital cardiac arrest (OHCA). We aimed to investigate whether adopting our hypothesized criteria for ECPR to patients with refractory OHCA could benefit. This before-after study compared 4.5 years after implementation of ECPR for refractory OHCA patients who met our criteria (Jan, 2015 to May, 2019) and 4 years of undergoing conventional CPR (CCPR) prior to ECPR with patients who met the criteria (Jan, 2011 to Jan, 2014) in the emergency department. The primary and secondary outcomes were good neurologic outcome at 6-months and 1-month respectively, defined as 1 or 2 on the Cerebral Performance Category score. A total of 70 patients (40 with CCPR and 30 with ECPR) were included. For a good neurologic status at 6-months and 1-month, patients with ECPR (33.3%, 26.7%) were superior to those with CCPR (5.0%, 5.0%) (all Ps < 0.05). Among patients with ECPR, a group with a good neurologic status showed shorter low-flow time, longer extracorporeal membrane oxygenation duration and hospital stays, and lower epinephrine doses used (all Ps < 0.05). The application of the detailed indication before initiating ECPR appears to increase a good neurologic outcome rate.

Background: Early initiation of hypothermia has shown to be important to reduce brain injuries in experimental cardiac arrest models. The aim of this study was to investigate the association between time to initiate cooling and neurological intact survival in patients with out-of-hospital cardiac arrest (OHCA). Methods: A secondary analysis of prospectively collected data from the PRINCESS trial (NCT01400373) including 677 OHCA patients randomized to transnasal evaporative intra-arrest cooling or standard advanced life support and cooling started subsequent to hospital arrival. Time to randomization was used a proxy measurement for time to initiate cooling. An early treatment group was defined as patients randomized by the EMS <20 minutes from the time of the cardiac arrest. Propensity scores were used to find matching patients in the control group. Patients with initial shockable rhythms were analyzed as a predefined subgroup. The primary outcome was good neurologic outcome, Cerebral Performance Category (CPC) 1-2 at 90 days. Secondary outcome was complete recovery (CPC 1). Results: In total 406 patients were randomized <20 minutes from the cardiac arrest and were propensity score matched (1:1). In the propensity score matched analysis the proportion of patients with CPC 1-2 was 21.7% in the intervention and 17.2% in the control group, odds ratio (OR) 1.33, 95% confidence interval (CI) 0.80-2.21, p=0.273. In patients with initial shockable rhythm (79 intervention, 79 control) the difference in CPC 1-2 was 48.1% versus 32.0%, OR 2.05, 95%CI 1.00-4.21, p=0.0498. The proportion of patients with complete neurologic recovery, CPC 1, was 19.7% in the intervention and 13.3% in the control group, OR 1.60, 95% CI 0.92-2.79, p=0.097. In patients with initial shockable rhythm the proportion with CPC 1 was 45.6% versus 24.6%, OR 2.81, 95% CI 1.23-6.42, p=0.014. Conclusions: In this ancillary study of OHCA patients receiving intra-arrest cooling, there were differences in survival with good neurologic outcome and in complete neurological recovery in favor of early intra-arrest cooling patient group compared to standard care. These differences were statistically significant in the subgroup of patients with initial shockable rhythms.

Abstract Background: Early defibrillation is vital to improve outcomes after out-of-hospital cardiac arrest (OHCA) with shockable rhythm. Currently, there is no agreed consensus on the number of defibrillation attempts before transfer to a hospital. This study aimed to evaluate the correlation between the number of defibrillations on the prehospital return of spontaneous circulation (ROSC).Methods: A multicenter, prospective, observational registry-based study was conducted for OHCA in patients with presumed cardiac etiology that underwent prehospital defibrillation between October 2015 and June 2017. The primary outcome was prehospital ROSC, and the secondary outcome was a good neurologic outcome at hospital discharge, defined as Cerebral Performance Category score 1 or 2. Results: Among 2,155 OHCA patients’ data, 178 patients with missing data were excluded, a total of 1,983 OHCA patients who received prehospital defibrillation were included. The median age was 61 years and prehospital ROSC was observed in 738 patients (37.2%). The median time from arrest to first defibrillation was 10 (interquartile range: 7-15) minutes. The cumulative ROSC rates and good neurologic outcome from the initial defibrillation to the sixth defibrillation were 43%, 68%, 81%, 90%, 95%, 98% and 42%, 66%, 81%, 90%, 95%, 98%, respectively. After clinical characteristics adjustment and time to defibrillation, the number of defibrillations were independently associated with ROSC (odds ratio 0.81 95% CI 0.76-0.86) and good neurologic outcome (odds ratio 0.86 95% CI 0.80-0.91). Moreover, subgroup analysis results with patients that underwent the initial defibrillation within 10 minutes from arrest were consistent (95% up to five times).Conclusion: More than 95% of prehospital ROSC was achieved within five times of defibrillation in OHCA patients. This result provides a basis for the ideal number of defibrillation attempts before transfer to hospital with the possibility of extracorporeal cardiopulmonary resuscitation in these refractory ventricular fibrillation patients.

Abstract The management of Out of hospital Traumatic Cardiac Arrest (TCA) for professional rescuers combines advanced life support with specifics actions to treat potential reversible causes of the arrest: hypovolemia, hypoxemia, Tension Pneumothorax (TPx) and tamponade. The aim of this study was to assess the impact of specific rescue gestures on short-term outcomes in the context of resuscitation of patients with a pre-hospital TCA.Methods: We conducted a retrospective study of all TCA treated in two emergency medical units (EM unit), which are part of the Northern Alps emergency network, from January 2004 to December 2017. Utstein variables and specific rescue actions in TCA were compiled: advanced airway management, fluid administration, pelvic stabilization or tourniquet application, bilateral thoracostomy, and thoracotomy procedures. The primary end point was the survival rate at day 30 with good neurologic outcome (cerebral performance category [CPC] score 1 & 2).Results: 287 resuscitations attempt in TCA were included and 279 specific interventions were Identified: 262 Fluid expansion, 41 External Pelvic stabilizations, 5 tourniquets, 175 bilateral thoracostomies, (including 44 with TPx).Conclusion: Among standard resuscitation measures to treat reversible causes of cardiac arrest, we were able to show that bilateral thoracostomy and tourniquet application on a limb hemorrhage improves survival of TCA. A larger sample for pelvic stabilization is necessary.

Introduction: Over 200,000 patients are treated annually in the United States for in-hospital cardiac arrest (IHCA). Patients with an initial rhythm of ventricular fibrillation or pulseless ventricular tachycardia (VF/pVT) have a survival rate of less than 50%. The current American Heart Association (AHA) Advanced Cardiovascular Life Support guidelines suggest amiodarone or lidocaine as first-line agents for shock-refractory VF/pVT based on randomized clinical trials in adults with out-of-hospital cardiac arrest. Based on these results, we hypothesized that amiodarone and lidocaine have equivalent efficacy in treating hospitalized patients with VF/pVT. Methods: This is a retrospective risk-adjusted cohort study using the AHA Get with the Guidelines-Resuscitation® (GWTG-R) registry. The study included adult patients between January 1, 2000 to December 31, 2014 with IHCA due to VF/pVT that received either amiodarone or lidocaine. The primary outcome was return of spontaneous circulation (ROSC). Secondary outcomes were 24-hour survival, survival to hospital discharge, and survival with favorable neurologic outcome based on Cerebral Performance Category (CPC) 1 or 2. Results: A total of 14,630 events were included in the analysis. Among patients who met inclusion criteria, 68.7% (n=10,058) were treated with amiodarone and 31.3% (n=4,572) were treated with lidocaine. Results from multivariable logistic regression analysis showed that, controlling for 19 covariates, ROSC rates were not statistically different with lidocaine treatment vs. amiodarone (AOR = 1.02, 95% CI 0.94, 1.11). However, lidocaine treatment was associated with higher odds of a) 24-hour survival, AOR = 1.14, 95% CI 1.06, 1.23; b) survival to discharge, AOR = 1.15, 95% CI 1.06, 1.24; and c) favorable neurologic outcome at hospital discharge, AOR = 1.21, 95% CI 1.11, 1.31. Conclusion: In adult IHCA patients with VF/pVT, treatment with lidocaine compared to amiodarone was not associated with higher ROSC rates, but was associated with higher rates of survival and favorable neurological outcomes. Additional research is needed to determine the optimal antiarrhythmic therapy for VF/pVT in IHCA.

Background: Early return of spontaneous circulation (ROSC) leads to survival with a favorable neurologic outcome in patients with out-of-hospital cardiac arrest (OHCA). For the early ROSC, defibrillation plays a crucial role for OHCA with shockable rhythm. However, little is known about the relation between the number of prehospital defibrillation attempts or etiology of OHCA and neurologically intact survival. Methods: Using a nationwide OHCA registry database from 2005 to 2017 in Japan, a cohort of 1,527,447 patients with OHCA were retrospectively analyzed. We included the patients of witnessed OHCAs with initial shockable rhythm. The relation between early ROSC, defined as prehospital ROSC achieved with defibrillation ≤3 times without adrenaline, and a neurologically intact survival rate (cerebral performance category score of 1 or 2 at 1 month) was evaluated. We also analyzed factors related to the successful early ROSC, including etiology of OHCA. Results: A total of 75,342 patients were included. Among patients with OHCA and prehospital ROSC, neurologically intact survival rates were better in patients who achieved early ROSC than their counterpart (62% vs. 36%, p<0.001). Success in early ROSC was an independent predictor of neurologically intact survival after adjustment of multiple cofounders (Table). Multivariate analysis showed cerebral vascular disease as an etiology of OHCA was a predictor of early ROSC (odds ratio 1.15, 95% confidence interval 1.03-1.29, p=0.02), but was significantly associated with a poor neurologic outcome at 1 month (Table). Conclusions: Success in early ROSC was associated with neurologically intact survival in patients with OHCA and initial shockable rhythm. Patients with OHCA due to cerebral vascular disease were likely to be resuscitated from cardiac arrest by defibrillations but had a poor neurologic outcome.

Background: Inadequate cerebral oxygenation is a risk factor for neurologic damage in successfully resuscitated cardiac arrest patients. One therapy to address this problem is early goal-directed hemodynamic optimization. However, the role of hemoglobin (Hgb) levels, a potential target for optimization, on outcomes in post-cardiac arrest patients is not known. Objective: To determine the association between Hgb levels in post-cardiac arrest patients and neurologic outcome (dichotomized into “good,” a Cerebral Performance Category (CPC) of 1 or 2 and “poor,” a CPC of 3, 4, or 5, at hospital discharge). The association between Hgb levels and survival to discharge was analyzed as a secondary outcome. Methods: A retrospective cohort study was conducted to compare patient demographics and Hgb levels. Hgb was analyzed as both a continuous and binary variable. To determine the association between Hgb levels and outcomes, multivariate logistic regression models controlling for gender, age, pulseless rhythm, and transfusion were used. Results: There were 598 eligible subjects from 21 hospitals in the US. Patients with ≤10 g/dL of Hgb had a higher percentage of subjects with good neurologic outcome than those with Hgb levels below 10 g/dL (41% vs. 26%; p < 0.001). Patients with good neurologic outcome had higher median Hgb levels in the first six hours after arrest than those with a poor neurologic outcome (12.6 g/dL vs. 10.5 g/dL; p < 0.001). Controlling for gender, age, pulseless rhythm, and transfusion, there was a significant relationship between Hgb levels within the first six hours after arrest and good neurologic outcome (OR: 1.21, 95% CI: 1.06 [[Unable to Display Character: &#8211;]] 1.39) and the first 24 hours after arrest and good neurologic outcome (OR: 1.14, 95% CI: 1.01 [[Unable to Display Character: &#8211;]] 1.28). There was a significant association between Hgb levels within the first six hours after arrest and survival to discharge (OR: 1.22, 95% CI: 1.07 [[Unable to Display Character: &#8211;]] 1.39) and Hgb levels within the first 24 hours after arrest and survival to discharge (OR: 1.14, 95% CI: 1.02 [[Unable to Display Character: &#8211;]] 1.28). Conclusions: Higher hemoglobin levels, particularly within the first six hours after cardiac arrest, are associated with better neurologic outcomes at hospital discharge in post-cardiac arrest patients admitted to the hospital.

Background: Impella CP is a left ventricular pump which may serve as a circulatory support during cardiopulmonary resuscitation (CPR) for cardiac arrest (CA). Nevertheless, the survival rate and factors associated with survival in patients undergoing Impella insertion during CPR for CA are unknown. Methods: We performed a retrospective multicenter international registry of patients undergoing Impella insertion during on-going CPR for in- or out-of-hospital CA. We recorded immediate and 30-day survival with and without neurologic impairment using the cerebral performance category score and evaluated the factors associated with survival. Results: Thirty-five patients had an Impella CP implanted during CPR for CA. Refractory ventricular arrhythmias were the most frequent initial rhythm (65.7%). In total, 65.7% of patients immediately survived. At 30 days, 45.7% of patients were still alive. The 30-day survival rate without neurological impairment was 37.1%. In univariate analysis, survival was associated with both an age < 75 years and a time from arrest to CPR ≤ 5 min (p = 0.035 and p = 0.008, respectively). Conclusions: In our multicenter registry, Impella CP insertion during ongoing CPR for CA was associated with a 37.1% rate of 30-day survival without neurological impairment. The factors associated with survival were a young age and a time from arrest to CPR ≤ 5 min.

Abstract Background Cardiopulmonary resuscitation (CPR) manoeuvres involve vigorous compressions with the proper depth and rate in order to keep sufficient perfusion to organs, especially the brain. Accordingly, high incidences of CPR-related injuries (CPR-RI) have been observed in survivors after cardiac arrest (CA). Purpose To analyse whether CPR-related injuries have an impact on the survival and neurological outcomes of comatose survivors after CA. Methods Observational prospective database of consecutive patients (pts) admitted to the acute cardiac care unit of a tertiary university hospital after in-hospital and out-of-hospital CA (IHCA and OHCA) treated with targeted temperature management (TTM 32–34°) from August 2006 to December 2019. CPR-RI were diagnosed by reviewing medical records and analysing image studies during hospitalization. Results A total of 498 pts were included; mean age was 62.7±14.5 years and 393 (78.9%) were men. We found a total of 145 CPR-RI in 109 (21.9%) pts: 79 rib fractures, 20 sternal fractures, 5 hepatic, 5 gastrointestinal, 3 spleen, 1 kidney, 26 lung and 6 heart injuries. Demographic characteristics and cardiovascular risk factors did not differ between the non-CPR-RI group and CPR-RI group. Also, we did not find differences in CA features (Table 1). Survival at discharge was higher in the CPR-RI group [74 (67.8%) vs 188 (48.3%); p&lt;0.001]. Moreover, Cerebral Performance Category (CPC) 1–2 within a 3-month follow-up was significantly higher in the CPR-RI group [(71 (65.1%) vs 168 (43.2%); p&lt;0.001; Figure 1]. Finally, pts who recieved blood transfusions were proportionally higher in the CPR-RI group [34 (32.1%) vs 65 (16.7%)]; p=0.004). Conclusions In our cohort, the presence of CPR-RI was associated with higher survival at discharge and better neurological outcomes during follow-up.
