[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.

Cardiopulmonary resuscitation-induced consciousness is a rarely described and often misunderstood phenomenon, although it can be encountered. High quality cardiopulmonary resuscitation (CPR) may lead a patient to recover consciousness while in cardiac arrest. The authors present the case of an 89-year-old male patient who received CPR after a cardiac arrest. Spontaneous movements during CPR were noted and prompted several CPR interruptions. These movements immediately stopped during chest compression pauses. Physical restraint was used in order to be able to continue with the CPR algorithm, but sedation may be the best approach. Guidelines on how to identify and manage these cases need to be developed.

Background: High-quality chest compression is crucial for cardiac arrest patients. However, only few studies are focusing on the optimal compression point. Objective: The aim of this study was to explore the optimal compression point based on chest-computed tomography. Methods: We retrospectively selected 166 adult health subjects between January 2018 and May 2018 in a university-affiliated hospital. Results: The median length of sternum was 14.9 cm. The median length from the inter-nipple line to the distal end of sternum was 1.0 cm. The median length from the point at which the maximal left ventricular diameter projected onto the sternum to the distal end of the sternum was −1.4 (–2.2 to 0.0) cm. The median value of the length from the inter-nipple line to the distal end of sternum plus the length from the point at which the maximal left ventricular diameter projected onto the sternum to the distal end of the sternum was 2.0 (1.0–3.1) cm. Conclusion: One size does not fit all. The point recommended by the current guideline may not appropriate for Chinese person. Further studies are required focusing on individual chest compression during cardiopulmonary resuscitation.

High-quality cardiopulmonary resuscitation (CPR) with targeted post-arrest management have resulted in dramatic improvements in survival with favourable neurological outcome from in-hospital paediatric cardiac arrest over the past two decades. High-quality CPR focuses on five key components: (1) chest compression depth of at least one-third of the anterior–posterior chest diameter; (2) chest compression rate between 100 and 120 compressions per minute; (3) limitation of interruptions in chest compressions; (4) full chest recoil between compressions; and (5) avoidance of overventilation. Quantitative capnography with a target end-tidal CO2 of at least 20 mmHg and invasive arterial blood pressure monitoring targeting a diastolic blood pressure of at least 25 mmHg in infants and 30 mmHg in children during chest compressions are promising markers of effective CPR. Post-arrest management should target normoxia, normocarbia, normotension for age, and normoglycaemia with active targeted temperature management to prevent hyperthermia and surveillance for and aggressive treatment of seizures.

The Impact

Introduction: High-quality cardiopulmonary resuscitation (CPR) is essential for patient survival. Typically, CPR quality is only measured during the first 10 minutes of resuscitation. There is limited research examining the quality of CPR over the entire duration of resuscitation.Objective: To examine the quality of CPR over the entire duration of resuscitation and correlate the quality of CPR to patient survival. Methods: This was a retrospective observational study using data from the Toronto RescuNET Epistry-Cardiac Arrest database. We included consecutive, adult (>18) OHCA treated by EMS between January 1, 2014 and September 30, 2015. High-quality CPR was defined, in accordance with 2015 AHA Guidelines, as a chest compression rate of 100-120/min, depth of 5.0-6.0 cm and chest compression fraction (ccf) of >0.80. We further categorized high-quality resuscitation as meeting benchmarks >80% of the time, moderate-quality between 50-80% and low-quality meeting benchmarks <50% of the resuscitation. We used multivariable logistic regression to determine association between variables of interest, including CPR quality metrics, and survival to hospital discharge. Results: A total of 5,208 OHCA met our inclusion criteria with a survival rate of 8%. The median (IQR) duration of resuscitation was 23.0 min (15.0,32.7). Overall CPR quality was considered high-quality for ccf in 81% of resuscitation episodes, 41% for rate, and 7% for depth. The percentage of resuscitations meeting the quality benchmarks differed between survivors and non-survivors for both depth (15% vs 6%) and ccf (61% vs 83%) (P value <0.001). After controlling for Utstein variables maintaining a chest compression depth within recommendations for >80% showed a trend towards improved survival (OR 1.68, 95% CI 0.96, 2.92). Other variables associated with survival were public location, initial CPR by EMS providers or bystanders, witnessed cardiac arrest (EMS or bystander), and initial shockable rhythm. Increasing age and longer duration of resuscitation were associated with decreased survival. Conclusion: Overall, EMS providers were not able to maintain rate or depth within guideline recommendations for the majority of the duration of resuscitation. Maintaining chest compression depth for greater than 80% of the resuscitation showed a trend towards increased survival from OHCA.

Abstract Background/Introduction Shockable rhythm after cardiac arrest is highly expected after early initiation of bystander cardiopulmonary resuscitation (CPR) owing to increased coronary perfusion. However, the relationship between bystander CPR and initial shockable rhythm in patients with out-of-hospital cardiac arrest (OHCA) remains unclear. We hypothesized that chest-compression-only CPR (CC-CPR) before emergency medical service (EMS) arrival has an equivalent effect on the likelihood of initial shockable rhythm to the standard CPR (chest compression plus rescue breathing [S-CPR]). Purpose We aimed to examine the rate of initial shockable rhythm and 1-month outcomes in patients who received bystander CPR after OHCA. Methods The study included 59,688 patients (age, ≥18 years) who received bystander CPR after an OHCA with a presumed cardiac origin witnessed by a layperson in a prospectively recorded Japanese nationwide Utstein-style database from 2013 to 2017. Patients who received public-access defibrillation before arrival of the EMS personnel were excluded. The patients were divided into CC-CPR (n=51,520) and S-CPR (n=8168) groups according to the type of bystander CPR received. The primary end point was initial shockable rhythm recorded by the EMS personnel just after arrival at the site. The secondary end point was the 1-month outcomes (survival and neurologically intact survival) after OHCA. In the statistical analyses, a Cox proportional hazards model was applied to reflect the different bystander CPR durations before/after propensity score (PS) matching. Results The crude rate of the initial shockable rhythm in the CC-CPR group (21.3%, 10,946/51,520) was significantly higher than that in the S-CPR group (17.6%, 1441/8168, p<0.0001) before PS matching. However, no significant difference in the rate of initial shockable rhythm was found between the 2 groups after PS matching (18.3% [1493/8168] vs 17.6% [1441/8168], p=0.30). In the Cox proportional hazards model, CC-CPR was more negatively associated with the initial shockable rhythm before PS matching (unadjusted hazards ratio [HR], 0.97; 95% confidence interval [CI], 0.94–0.99; p=0.012; adjusted HR, 0.92; 95% CI, 0.89–0.94; p<0.0001) than S-CPR. After PS matching, however, no significant difference was found between the 2 groups (adjusted HR of CC-CPR compared with S-CPR, 0.97; 95% CI, 0.94–1.00; p=0.09). No significant differences were found between C-CPR and S-CPR in the 1-month outcomes after PS matching as follows, respectively: survival, 8.5% and 10.1%; adjusted odds ratio, 0.89; 95% CI, 0.79–1.00; p=0.07; cerebral performance category 1 or 2, 5.5% and 6.9%; adjusted odds, 0.86; 95% CI, 0.74–1.00; p=0.052. Conclusions Compared with S-CPR, the CC-CPR before EMS arrival had an equivalent multivariable-adjusted association with the likelihood of initial shockable rhythm in the patients with OHCA due to presumed cardiac causes that was witnessed by a layperson.

Hospital Cardiac Arrest

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.
