BACKGROUND: Although previous studies have shown marked variation in out-of-hospital cardiac arrest survival across US regions, factors underlying this survival variation remain incompletely explained. METHODS AND RESULTS: Using data from the Cardiac Arrest Registry to Enhance Survival, we identified 96 662 adult patients with out-of-hospital cardiac arrest in 132 US counties. We used hierarchical regression models to examine county-level variation in rates of survival and survival with functional recovery (defined as Cerebral Performance Category score of 1 or 2) and examined the contribution of demographics, cardiac arrest characteristics, bystander cardiopulmonary resuscitation, automated external defibrillator use, and county-level sociodemographic factors in survival variation across counties...

AIM: The American Heart Association (AHA) recommends monitoring invasive arterial diastolic blood pressure (DBP) and end-tidal carbon dioxide (ETCO2) during cardiopulmonary resuscitation (CPR) when available. In intensive care unit patients, both may be available to the rescuer. The objective of this study was to compare DBP vs. ETCO2 during CPR as predictors of cardiac arrest survival. METHODS: In two models of cardiac arrest (primary ventricular fibrillation [VF] and asphyxia-associated VF), 3-month old swine received either standard AHA guideline-based CPR or patient-centric, BP-guided CPR...

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (ECMO) is rapidly evolving as bailout option in patients with refractory cardiogenic shock after cardiovascular surgery (CV). Cardiac arrest represents a common and severe complication in the immediate post-operative phase. We therefore evaluated the impact of cardiac arrest at time of ECMO implantation on short- and long-term mortality in patients following CV surgery. METHODS AND RESULTS: We included 385 patients undergoing veno-arterial extracorporeal membrane oxygenation therapy following CV surgery at a university-affiliated tertiary-care center into our single-center registry...

AIM: Chest compressions during cardiopulmonary resuscitation (CPR) increase arterial and venous pressures, delivering simultaneous bidirectional high-pressure compression waves to the brain. We hypothesized that this may be detrimental and could be partially overcome by elevation of the head during CPR. MEASUREMENTS: Female Yorkshire farm pigs (n=30) were sedated, intubated, anesthetized, and placed on a table able to elevate the head 30° (15cm) (HUP) and the heart 10° (4cm) or remain in the supine (SUP) flat position during CPR...

OBJECTIVE: Bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) has the ability to improve patient survival. However, the rates at which CPR occurs are suboptimal. We hypothesized that targeted CPR training in neighborhoods with low bystander CPR and high incidence of cardiac arrests would increase the incidence of bystander CPR for adult OHCA. METHODS: This study is a descriptive observation and analysis of the TAKE 10 program, which recruited City of Austin and Travis County residents to teach fellow community members compression-only CPR...

INTRODUCTION: This study compared the effects of vasopressin via tibial intraosseous (IO) and intravenous (IV) routes on maximum plasma concentration (Cmax), the time to maximum concentration (Tmax), return of spontaneous circulation (ROSC), and time to ROSC in a hypovolemic cardiac arrest model. METHODS: This study was a randomized prospective, between-subjects experimental design. A computer program randomly assigned 28 Yorkshire swine to one of four groups: IV (n=7), IO tibia (n=7), cardiopulmonary resuscitation (CPR) + defibrillation (n=7), and a control group that received just CPR (n=7)...

BACKGROUND: The determination of appropriate duration of in-the-field cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients is one of the biggest challenges for emergency medical service providers and clinicians. The appropriate CPR duration before termination of resuscitation remains unclear and may differ based on initial rhythm. We aimed to determine the relationship between CPR duration and post-OHCA outcomes. METHODS AND RESULTS: We analyzed the records of 17 238 OHCA patients (age ≥18 years) who achieved prehospital return of spontaneous circulation...

Pulmonary embolism (PE) remains a major contributor to global disease burden. Risk-adapted treatment and follow-up contributes to a favorable outcome. Age-adjusted cutoff levels increase D-dimer specificity and may decrease overuse of imaging procedures and overdiagnosis of PE. Primary systemic fibrinolysis has an unfavorable risk-benefit ratio in intermediate-risk PE; catheter-directed techniques are an option for patients with hemodynamic decompensation and high bleeding risk. New oral anticoagulant agents are effective and safe alternatives to standard anticoagulation regimens...

Objective. Out of hospital cardiac arrest (OHCA) patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH) with early coronary intervention may improve outcomes in this population. The aim of this study was to evaluate predictors of mortality in OHCA patients undergoing MTH with and without cardiac catheterization. Design. A retrospective cohort of OHCA patients who underwent MTH with catheterization (MTH + C) and without catheterization (MTH + NC) between 2006 and 2011 was analyzed at a single tertiary care centre...

BACKGROUND: Previous guidelines suggest up to 15 minutes of cardiopulmonary resuscitation (CPR) accompanied by other resuscitative interventions before terminating resuscitation of a traumatic cardiac arrest. The current study evaluated the duration of CPR according to outcome using the model of a county-based emergency medical services (EMS) system in Taiwan. METHODS: This study was performed as a prospectively defined retrospective review from EMS records and cardiac arrest registration between June 2011 and November 2012 in Taoyuan, Taiwan...

BACKGROUND: The benefit of extracorporeal life support (ECLS) in highly selective patients with out-of-hospital cardiac arrest (OHCA) is supported by previous studies; however, it is unclear whether the effects of ECLS are observed at a population level. This study aimed to determine whether ECLS is associated with improved survival outcomes compared to conventional CPR (cardiopulmonary resuscitation) at a national level. METHODS: We used a Korean national OHCA cohort database from 2009 to 2013...

INTRODUCTION: The optimal temperature during targeted temperature management (TTM) for comatose patients resuscitated from out-of-hospital cardiac arrest is unknown. It has been hypothesized that patients with long no-flow times, for example those without bystander CPR would have the most to gain from temperature management at lower temperatures. METHODS: We analysed data from an international clinical trial randomizing cardiac arrest patients to targeted temperature management at 33°C and 36°C for an interaction between no-flow time and intervention group, with neurological function at six months after cardiac arrest as the primary outcome...

We present a rare case of a left internal mammary artery rupture during cardiopulmonary resuscitation (CPR). This case demonstrates that intrinsic cardiac/vascular injuries can occur even with manual CPR, and each patient should be monitored closely, considering the very subtle signs that can clue the physicians into the diagnosis.

BACKGROUND: Socioeconomic factors of a community are associated with bystander cardiopulmonary resuscitation (BCPR) rates and outcomes of out-of-hospital cardiac arrest (OHCA). This study aimed to test whether dispatcher-provided CPR instruction modifies the association between education level of a community and provision of BCPR. METHODS: A population-based observational study was conducted with OHCAs of cardiac etiology who were witnessed by laypersons between 2012 and 2013...

AIM: To investigate the influence of dosing frequency and dosage of adrenaline on outcomes of cardiopulmonary resuscitation (CPR). METHODS: We conducted a retrospective observational study in a single medical centre and included adult patients who had suffered an in-hospital cardiac arrest between 2006 and 2012. We used multivariable logistic regression analysis to evaluate the associations between independent variables and outcomes. Adrenaline average dosing frequency was calculated as the total dosage of adrenaline administered during CPR divided by the duration of CPR...

BACKGROUND: Evidence suggests that EMS-physician-guided cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OOHCA) may be associated with improved outcomes, yet randomized controlled trials are not available. The goal of this meta-analysis was to determine the association between EMS-physician- versus paramedic-guided CPR and survival after OOHCA. METHODS AND RESULTS: Studies that compared EMS-physician- versus paramedic-guided CPR in OOHCA published until June 2014 were systematically searched in MEDLINE, EMBASE and Cochrane databases...
