Cerebral ischemia/reperfusion (I/R) triggers a cascade of uncontrolled cellular processes that perturb cell homeostasis. The arctic ground squirrel (AGS), a seasonal hibernator resists brain damage following cerebral I/R caused by cardiac arrest and resuscitation. However, it remains unclear if tolerance to I/R injury in AGS depends on the hibernation season. Moreover, it is also not clear if events such as depletion of ATP, acidosis and glutamate efflux that are associated with anoxic depolarization are attenuated in AGS...

OBJECTIVE: Pharmacokinetic parameters of drugs are widely investigated under normothermic conditions and normal hemodynamic parameters. The European Resuscitation Council recommends the use of targeted temperature management (TTM) with a target temperature of 34 °C in cardiac arrest (CA) patients. The aim of this literature review is to investigate the influence of CA combined with TTM on the pharmacokinetics of drugs. Results of preclinical and clinical studies are compared with each other...

Treatment with an implantable cardioverter-defibrillator (ICD) represents a prognostic but not symptomatic therapy. It should therefore be restricted to patients where an improvement of prognosis is possible and reasonable. ICD implantation should only be performed in patients with a life expectancy of at least 1 year at reasonable quality of life. The decision in which patient improvement of prognosis is no longer a desirable target is problematic, both medically and ethically. It is not entirely clear in which elderly patient an ICD therapy can convey prognostic benefit despite comorbidity and competitive life-threatening diseases, as it is unclear how old age should be defined...

PURPOSE: Few outcome data are available about temperature management after intraoperative cardiac arrest (IOCA). We describe targeted temperature management (TTM) (32-34 °C) modalities, adverse events, and association with 1-year functional outcome in patients with IOCA. METHODS: Patients admitted to 11 ICUs after IOCA in 2008-2013 were studied retrospectively. The main outcome measure was 1-year functional outcome. RESULTS: Of the 101 patients [35 women and 66 men; median age, 62 years (interquartile range, 42-72)], 68 (67...

AIMS: Patients in a coma after cardiac arrest may have adversely affected drug absorption and metabolism. This study, the first of its kind, aimed to investigate the early pharmacokinetic and pharmacodynamic effects of ticagrelor administered through a nasogastric tube (NGT) to patients resuscitated after an out of hospital cardiac arrest (OHCA) and undergoing primary percutaneous coronary intervention (pPCI). METHODS AND RESULTS: Blood samples were drawn at baseline and at two, four, six, eight, 12, and 24 hours and then daily for up to five days after administration of a 180 mg ticagrelor loading dose (LD), followed by 90 mg twice daily in 44 patients...

AIM: The prognostic effect of early coronary reperfusion therapy with extracorporeal cardiopulmonary resuscitation (ECPR) in patients with cardiac arrest due to acute coronary syndrome (ACS) has yet to be clarified. We investigated the relationship between time interval from collapse to start of ECPR (CtoE) and coronary reperfusion (CtoR) time and neurological outcome in patients with cardiac arrest due to ACS. METHODS: A cohort of 119 consecutive patients (63±12 years old) with ACS who underwent ECPR and percutaneous coronary intervention(PCI) at our hospital was registered from January 2005 to June 2016...

BACKGROUND: In refractory cardiac arrest, with cardiopulmonary resuscitation (CPR) for more than 30 min, chances of survival are small. Extracorporeal cardiopulmonary resuscitation (ECPR) is an option for certain patients with cardiac arrest. The aim of this study was to evaluate characteristics of patients selected for ECPR. METHODS: Anonymised data of adult patients suffering refractory cardiac arrest, transported with ongoing CPR to an ED of a tertiary care centre between 2002 and 2012 were analysed...

To assess the significance of an analogue of the mean systemic filling pressure (Pmsa) and its derived variables, in providing a physiology based discrimination between responders and non-responders to fluid resuscitation during liver surgery. A post-hoc analysis of data from 30 patients undergoing major hepatic surgery was performed. Patients received 15 ml kg(-1) fluid in 30 min. Fluid responsiveness (FR) was defined as an increase of 20% or greater in cardiac index, measured by FloTrac-Vigileo(®). Dynamic preload variables (pulse pressure variation and stroke volume variation: PPV, SVV) were recorded additionally...

Myocarditis is an inflammatory disease of the myocardium with heterogeneous clinical manifestations and progression. In clinical practice, although there are many methods of diagnosis of acute myocarditis, the diagnosis remains an embarrassing dilemma for clinicians. The authors report the case of 9-month-old infant who was brought to the Pediatric Emergency Department with sudden onset dyspnea. Examination disclosed heart failure and resuscitation was undertaken. The electrocardiogram showed an ST segment elevation in the anterolateral leads with a mirror image...

Mortality during pregnancy in a well-resourced setting is rare, but acute pulmonary embolism is one of the leading causes. We present the successful use of extracorporeal cardiopulmonary resuscitation (eCPR) in a 22-year old woman who experienced cardiopulmonary collapse following urgent caesarean section in the setting of a sub-massive pulmonary embolus. Resources and personnel to perform eCPR were not available at the maternity hospital and were recruited from an adjacent pediatric hospital. Initial care used low blood flow extracorporeal membrane oxygenation (ECMO) with pediatric ECMO circuitry, which was optimized when the team from a nearby adult cardiac hospital arrived...

Survivors of out-of-hospital cardiac arrest (OHCA) have high mortality and morbidity. An acute coronary event is the most common cause of sudden cardiac death. For this reason, coronary angiography is an important diagnostic and treatment strategy for patients with postcardiac arrest. This study aimed to identify the correlation between postreturn of spontaneous circulation (ROSC) on an electrocardiogram (ECG) and results of coronary angiography of OHCA survivors.We collected data from our OHCA registry from January 2010 to November 2014...

: Most survival outcomes in out-of-hospital cardiac arrest (OHCA) are provided by emergency medical services (EMS) without a doctor on board. Our objective was to determine such outcomes in a whole country with public physician-led EMS. METHODS: We analyzed data from a nationwide prospective registry of OHCA cases attended by emergency medical teams (EMS) of 19 Public EMS in Spain, covering the period from 1 October 2013 to 30-October 2014 (13 months). RESULTS: Advanced life support (ALS) was initiated in 9347 cases (incidence of 18...

Neurological injury develops over days following cardiac arrest (CA); however, the exact mechanisms remain unknown. After stroke or trauma, the progression of neurological injury is associated with cortical-spreading depolarizations (CSDs). The objective was to investigate whether CA and subsequent resuscitation in rats are associated with 1) the development of spontaneous negative direct current (DC) shifts indicative of CSDs, and 2) changes in artificially induced CSDs in the postresuscitation period. Male Sprague-Dawley rats were randomized into four groups: 1) CA 90, 2) Control 90, 3) CA 360, and 4) Control 360...
