[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.

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest. Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions. Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes. Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.

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.

Abstract Background The influence of past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events toward willingness to “pay it forward” by helping the next cardiac arrest victim was explored. Methods Using a validated questionnaire, 6248 participants were asked to rate their willingness to perform bystander chest compression with mouth-to-mouth ventilation and chest compression-only CPR. Their past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events were also recorded. Results Kruskal-Wallis test with post hoc Dunn’s pairwise comparisons showed that the following were significantly more willing to perform CPR with mouth-to-mouth ventilation: familial experience of “nonfatal cardiac events” (mean rank = 447) vs “out-of-hospital cardiac arrest with no CPR” (mean rank = 177), U = 35442.5, z = −2.055, p = 0.04; “in-hospital cardiac arrest and successful CPR” (mean rank = 2955.79) vs “none of these experiences” (mean rank = 2468.38), U = 111903, z = −2.60, p = 0.01; and “in-hospital cardiac arrest with successful CPR” (mean rank = 133.45) vs “out-of-hospital arrest with no CPR” (mean rank = 112.36), U = 4135.5, z = −2.06, p = 0.04. For compression-only CPR, Kruskal-Wallis test with multiple runs of Mann-Whitney U tests showed that “nonfatal cardiac events” group was statistically higher than the group with “none of these experiences” (mean rank = 3061.43 vs 2859.91), U = 1194658, z = −2.588, p = 0.01. The groups of “in-hospital cardiac arrest with successful CPR” and “in-hospital cardiac arrest with transient return of spontaneous circulation” were the most willing groups to perform compression-only CPR. Conclusion Prior familial experiences of receiving CPR and medical help, particularly among those with successful outcomes in a hospital setting, seem to increase the willingness to perform bystander CPR.

Background: The current guidelines emphasize that high-quality chest compression is essential for improving the survival in out-of-hospital cardiac arrest (OHCA) patients. However, it may lead to thoracic injuries which is a potential factor of poor prognosis. Method: Between June 2017 to July 2019, we collected Utstein-style data on 384 consecutive adult patients with non-traumatic OHCA who were transferred to our hospital. Full-body CT scan was performed and thoracic injuries were defined as rib fracture, sternum fracture, hemorrhagic pleural effusion, pneumothorax, sternum posterior bleeding, mediastinal hematoma, or mediastinal emphysema. We identified the predictors for thoracic injuries and evaluated the relationship between thoracic injuries and prognosis. Results: Patients with thoracic injuries (Group-T) were 234 (76%). The duration of chest compression in Group-T was 43 min, which was significantly longer than that in patients without thoracic injuries (Group-N, 32 min, p<0.001). ROC curve analysis identified a duration of chest compression of 35 minutes as the optimal cut off for predicting thoracic injuries (area under the curve 0.73). Multivariate analysis revealed that age (OR: 1.03, 95%CI: 1.01-1.05, p=0.005) and duration of chest compression (OR: 1.07, 95%CI: 1.04-1.09, p<0.001) were independent predictors of thoracic injuries. The rate of obtaining return of spontaneous circulation (ROSC), 30-day survival and favorable neurologic outcome were larger in Group-N than Group-T. In patients with achieving ROSC, Kaplan-Meier curves showed a significantly higher cumulative survival rates in Group-N compared to that in Group-T during follow-up of 30 days (Log-rank test p=0.009). Conclusion: Age and duration of chest compression were independent predictors for thoracic injuries due to chest compression in non-traumatic OHCA patients. Moreover, the presence of thoracic injuries was associated with poor short-term prognosis.

Introduction: Head computed tomography (CT) is frequently performed in survivors of out-of-hospital cardiac arrest (OHCA). However, the clinical utility of routine, early head CT in these patients is not well understood. We sought to characterize the associations between findings on early head CT with presenting characteristics and outcomes in survivors of OHCA. Hypothesis: Presence of early intracranial swelling is associated with poor outcomes. Methods: This is a retrospective analysis from a multicenter cohort of 432 patients with non-traumatic OHCA between 2/1/17 through 4/1/19. Patients were included if they underwent head CT <24 hrs after return of spontaneous circulation. Head CT findings were based on reads performed by local radiologists. Intracranial swelling was defined as loss of gray-white matter differentiation, sulcal effacement, and/or cerebral edema. Underlying cause of OHCA was adjudicated by trained physicians. Baseline characteristics and outcomes were compared between those with and without intracranial swelling. Result: Early head CT (<24 hrs) was performed in 378 (87.5%) patients with OHCA. Intracranial swelling was present in 97 (25.7%) patients with early head CT, and 14 (3.7%) had evidence of intracranial hemorrhage (ICH, Table). Of the patients presenting with ICH, 3/14 (21.4%) had shockable rhythms, 7/14 (50%) had subarachnoid hemorrhage, and ICH was the adjudicated cause of arrest in 10/14 (71.4%) patients. Patients with intracranial swelling were younger, less likely to have presented with a shockable rhythm, cardiac etiology, and witnessed OHCA. They were more likely to have a suppressed EEG, anoxia on MRI, and were less likely to survive to hospital discharge. Conclusions: In survivors of non-traumatic OHCA, routine, early (<24 hrs) head CT identified ICH in 3.7% of patients, and ICH was the adjudicated cause of arrest in 2.6% of patients. Intracranial swelling was present in more than 1/4 of patients, and associated with poor outcomes.
