Introduction: Mechanical chest compression (MCC) provides consistent pressure and timing of each chest compression in line with latest evidenced-based practice. However, there has been no evidence from large randomized trials about the effectiveness of the mechanical device compared with manual chest compression. Furthermore, few studies focused on cardiogenic shock and cardiac arrest related to heart disease. Hypothesis: The aim is to assess the effectiveness and safety of mechanical chest compressions versus manual chest compressions in patients with out of hospital cardiogenic shock and cardiac arrest due to heart disease. Methods: We conducted a retrospective observational study of comparing the outcomes of mechanical and manual chest compressions. A total of 69 consecutive patients with out of hospital cardiogenic shock and cardiac arrest were enrolled between April 2014 and May 2018. 39 patients of them received only manual cardiopulmonary resuscitation (CPR) and 30 utilized a mechanical CPR device. Baseline characteristics, resuscitation details, and outcomes were compared between patients who received manual (manual group) and mechanical compressions (MCC group). Results: There was no significant difference in age, gender, the rate of bystander CPR and arterial blood gases at baseline. No differences were found for the rate of ROSC and 30-day survival between two groups. However, MCC group had significantly higher rate of bleeding events than manual group. In addition, fifty-four patients of them were treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO). Among patients underwent VA-ECMO, the rate of 30-day survival was significantly lower in MCC group. (Figure 1). Conclusions: This study showed that mechanical chest compression increased bleeding events than manual chest compression. Furthermore, in the patients underwent ECMO, the use of mechanical chest compression might be associated with higher mortality.

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.

Sudden cardiac death is a leading cause of death worldwide, whereby myocardial infarction is considered the most frequent underlying condition. Percutaneous coronary intervention (PCI) is an important component of post-resuscitation care, while uninterrupted high-quality chest compressions are key determinants in cardiopulmonary resuscitation (CPR). In our paper, we evaluate a case of a female patient who suffered aborted cardiac arrest due to myocardial infarction. The ambulance crew providing prehospital care for sudden cardiac arrest used a mechanical chest compression device during advanced CPR, which enabled them to deliver ongoing resuscitation during transfer to the PCI laboratory located 20 km away from the scene. Mechanical chest compressions were continued during the primary coronary intervention. The resuscitation, carried out for 2 h and 35 min, and the coronary intervention were successful, as evidenced by the return of spontaneous circulation and by the fact that, after a short rehabilitation, the patient was discharged home with a favorable neurological outcome. Our case can serve as an example for the effective and safe use of a mechanical compression device during primary coronary intervention.

Abstract:: Despite the technological improvements of the last 40 years conditions such as refractory cardiogenic shock and cardiac arrest still present a very high mortality rate in the real-world clinical practice. In this light we have performed a review of the techniques, indications, contraindications and results of the so-called Veno-Arterial Extracorporeal Circulatory Membrane Oxygenation (VA-ECMO) in the adult population to evaluate the current results of this temporary cardio-pulmonary support as salvage and/or bridge therapy in patient suffering from refractory cardiogenic shock or cardio-circulatory arrest. The results are encouraging, especially in the setting of refractory cardiogenic shock and in-hospital cardiac arrest. Among a selected population the prompt institution of a VA-ECMO may radically change the prognosis by sustaining vital functions while looking for the leading cause or waiting for the reversal of the temporary cardio-respiratory negative condition. The future directions aim to standardized and shared protocols, miniaturization of the machines and possibly the institution of specialized “ECMO teams” for in and out-of-hospital institution of the tool.

INTRODUCTION Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an essential tool for the management of refractory cardiogenic shock. Little is known about the incidence of thromboembolic events after V-A ECMO decannulation, although some studies report a high incidence of cannula-related venous thrombosis after venovenous extracorporeal membrane oxygenation (VV-ECMO). Due to this fact, in our institution anticoagulation therapy is systematically prescribed for at least 3 months after VA-ECMO per protocol.  AIM The main objective of this study was to explore the feasibility of 3-month anticoagulation therapy after VA-ECMO decannulation. METHODS We performed a prospective study that included 27 consecutive patients who were successfully treated with VA-ECMO in a medical ICU between 2016 and 2019 and were prescribed 3-month anticoagulation therapy per protocol after decannulation. Exclusion criteria was dying on ECMO or while on the ICU. Data analysis included demographics, mean days on ECMO, 3-month survival, and thromboembolic and bleeding events (excluding immediate post-decannulation bleeding, since anticoagulation was prescribed 24h after). RESULTS Our cohort consisted mainly of men (N = 21, 78%), with a mean age of 60 ± 11 years and a mean time on VA-ECMO of 8 ± 3 days, who primarily suffered from post-cardiotomy cardiogenic shock (N = 9, 34%) or acute myocardial infarction (N = 6, 23%). 5 patients (18%) received a heart transplant. Regarding anticoagulation, 15 patients (60%) had other indications apart from the protocol, like incidental thrombus diagnosis (N = 7, 26%) or valve surgery (N = 5, 18%). Anticoagulation therapy was not feasible in 1 patient (4%) with severe thrombopenia. No patients had severe or life-threatening bleeding events in the follow-up, although 8 patients (30%) had bleeding events, mainly gastrointestinal bleeding (N = 4, 15%), requiring withdrawal of anticoagulation in 1 patient. The incidence of thromboembolic events was 7%; two patients with low-risk pulmonary embolisms. During the 3-month follow-up survival rate was 95%. CONCLUSIONS This is the only study to date addressing the strategy of 3-month anticoagulation therapy after VAECMO, showing it is feasible and safe and may be helpful in reducing or ameliorate thromboembolic complications in the follow-up, although it is not exempt of complications.

Abstract Funding Acknowledgements Type of funding sources: None. Background. The approach for veno-arterial extracorporeal membrane oxygenation implantation (VA-ECMO) in patients with cardiogenic shock can be either surgical or percutaneous. Angio-guided percutaneous implantation and explantation could decrease vascular complications. Purpose We sought to describe the feasibility and safety of complete percutaneous angio-guided ECMO implantation and explantation using preclosing. Methods. All consecutive patients who underwent peripheral femoro-femoral VA-ECMO percutaneous implantation for refractory cardiogenic shock or cardiac arrest were enrolled in a prospective registry (03/2018-09/2020). Percutaneous preclosing using two closing devices (Perclose ProGlide, Abbott) inserted before cannulation was used in both femoral artery and vein. Explantation was performed using a crossover technique under fluoroscopic guidance. The occurrence of vascular complication was recorded. Results. Forty-nine patients underwent percutaneous VA-ECMO implantation for cardiogenic shock (n = 36) or refractory cardiac arrest (n = 13). Femoral vessel cannulations were successful in all patients and total cannulation time was 21± 8 min. Weaning from ECMO was possible in 23 patients (47%) and 11 (22%) patients were alive at 30-day. Significant vascular complications occurred in 3 patients (6%); all were related to distal perfusion line. One patient experienced major bleeding, and 2 experienced lower limb ischemia requiring vascular intervention (one failure of distal perfusion sheath implantation and one self-uprooting of the reperfusion cannula). Percutaneous decannulation was performed in 17 patients with 16/17 technical success rate. All femoral arteries and veins were properly closed using the pre-closing devices without bleeding on the angiographic control except for one patient in whom surgical closure of the artery was required. Among these patients, none required transfusion for access related significant bleeding and no other vascular complication occurred. Furthermore, no groin infection was observed after full percutaneous implantation and removal of ECMO. Conclusion. Emergent complete percutaneous angio-guided VA-ECMO implantation and explantation using pre-closing technique is an effective and safe strategy in patients referred for refractory cardiogenic shock or cardiac arrest.

[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.

Introduction: Our goal was to systematically review contemporary literature comparing the relative effectiveness of two mechanical compression devices (LUCAS and AutoPulse) to manual compression for achieving return of spontaneous circulation (ROSC) in patients undergoing cardiopulmonary resuscitation (CPR) after an out-of-hospital cardiac arrest (OHCA). Methods: We searched medical databases systematically for randomized controlled trials (RCT) and observational studies published between January 1, 2000–October 1, 2020 that compared mechanical chest compression (using any device) with manual chest compression following OHCA. We only included studies in the English language that reported ROSC outcomes in adult patients in non-trauma settings to conduct random-effects metanalysis and trial sequence analysis (TSA). Multivariate meta-regression was performed using preselected covariates to account for heterogeneity. We assessed for risk of biases in randomization, allocation sequence concealment, blinding, incomplete outcome data, and selective outcome reporting. Results: A total of 15 studies (n = 18474), including six RCTs, two cluster RCTs, five retrospective case-control, and two phased prospective cohort studies, were pooled for analysis. The pooled estimates’ summary effect did not indicate a significant difference (Mantel-Haenszel odds ratio = 1.16, 95% confidence interval, 0.97 to 1.39, P = 0.11, I2 = 0.83) between mechanical and manual compressions during CPR for ROSC. The TSA showed firm evidence supporting the lack of improvement in ROSC using mechanical compression devices. The Z-curves successfully crossed the TSA futility boundary for ROSC, indicating sufficient evidence to draw firm conclusions regarding these outcomes. Multivariate meta-regression demonstrated that 100% of the between-study variation could be explained by differences in average age, the proportion of females, cardiac arrests with shockable rhythms, witnessed cardiac arrest, bystander CPR, and the average time for emergency medical services (EMS) arrival in the study samples, with the latter three attaining statistical significance. Conclusion: Mechanical compression devices for resuscitation in cardiac arrests are not associated with improved rates of ROSC. Their use may be more beneficial in non-ideal situations such as lack of bystander CPR, unwitnessed arrest, and delayed EMS response times. Studies done to date have enough power to render further studies on this comparison futile.
