[Background] Recently, the patients with out-of-hospital cardiac arrest are increasing. It is very important to do chest compression continuously for the return of spontaneous circulation (ROSC). But we can not but stop chest compression during checking pulse every few minutes. We reported that Regional cerebral Oxygen Saturation (rSO2) value was not elevated by manual chest compression and mechanical chest compression increased a little rSO2 value on CPR without ROSC and rSO2 value became a good parameter of ROSC in single center study. [Purpose] The purpose of this study is to evaluate clinical utility of rSO2 value during CPR in multicenter study. [Method] Retrospectively, we considered the rSO2 value of the out-of -hospital cardiac arrest patients from December 2012 to December 2014 in multicenter. During CPR, rSO2 were recorded continuously from the forehead of the patients by TOS-OR (Japan). CPR for patients with OHCA was performed according to the JRC-guidelines 2010. [Result] 252 patients with OHCA were included in this study. The rSO2 value on arrival, during CPR and ROSC were 44.4±8.9%, 45.4±9.7%, 58.6±9.2%. In ROSC, with rSO2 cutoff value of 52.7%, the specificity and sensitivity were 80% and 79%, respectively. The negative predict value was 99.2%, respectively. It means little possible to ROSC, if the rSO2 value is less than 52.7%. So, it may be possible to reduce the frequency of checking pulse during CPR. [Conclusion] The monitoring of rSO2 value could reduce the frequency of checking pulse during CPR and do chest compression continuously.

Abstract Background Mechanical circulatory support (MCS) with either extracorporeal membrane oxygenation or Impella has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to describe the gradual implementation, survival and adherence to the national consensus with respect to use of MCS for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving MCS for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan–Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day mortality. Results A total of 259 patients were included in the study. Thirty-day survival was 26%. Sixty-five (25%) survived to hospital discharge and a good neurological outcome (Glasgow–Pittsburgh Cerebral Performance Categories 1–2) was observed in 94% of these patients. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 min, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had reduced risk of 30-day mortality (RR 0.63, 95% CI 0.52–0.76). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with MCS for OHCA. Stringent patient selection for MCS may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors.

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.

Background: Previous investigations in human out of hospital cardiac arrest (OHCA) due to ventricular fibrillation (VF) have shown that the frequency-based waveform characteristic, amplitude spectral area (AMSA) predicts defibrillation success and is associated with survival to hospital discharge. We evaluated the relative strength of factors associated with hospital discharge including witnessed/unwitnessed status, chest compression (CC) quality and AMSA. We then investigated if there is a threshold value for AMSA that can identify patients who are unlikely to survive. Methods: Adult OHCA patients (age ≥18), with initial rhythm of VF from an Utstein-Style database (collected from 2 EMS systems) were analyzed. AMSA was measured from the waveform immediately prior to each shock, and averaged for each individual subject (AMSA-ave). Univariate and stepwise multivariable logistic regression, and receiver-operator-characteristic (ROC) analyses were performed. Factors analyzed: age, sex, witnessed status, time from dispatch to monitor/defibrillator application, number of shocks, mean CC rate, depth, and release velocity (RV). Results: 140 subjects were analyzed, [104 M (74%), age 62 ± 14 yrs, witnessed 65%]. Survival was 38% in witnessed and 16% in unwitnessed arrest. In univariate analyses, age (P=0.001), witnessed status (P=0.009), AMSA-ave (P<0.001), mean CC depth (P=0.025), and RV (P< 0.001) were associated with survival. Stepwise logistic regression identified AMSA-ave (P<0.001), RV (P=0.001) and age (P=0.018) as independently associated with survival. The area under the curve (ROC analysis) was 0.849. The probability of survival was < 5% in witnessed arrest for AMSA-ave < 5 mV-Hz, and in unwitnessed arrest for AMSA-ave < 15 mV-Hz. Conclusion: In OHCA with an initial rhythm of VF, AMSA-ave and CC RV are highly associated with survival. Further study is needed to evaluate whether AMSA-ave may be useful to identify patients highly unlikely to survive.

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.
