Our purpose was to analyze evidence related to timing of cooling from studies of targeted temperature management (TTM) after return of spontaneous circulation (ROSC) after cardiac arrest and to recommend directions for future therapy optimization. We conducted a preliminary review of studies of both animals and patients treated with post-ROSC TTM and hypothesized that a more rapid cooling strategy in the absence of volume-adding cold infusions would provide improved outcomes in comparison with slower cooling...

Post cardiac arrest, neuroprognostication remains a complex and clinically challenging issue for critical care providers. For this reason, our primary objective in this study was to determine the frequency of survival and favorable neurological outcomes in post-cardiac arrest patients with delayed time to awakening. To assess whether early withdrawal of care may adversely impact survival, we also sought to describe the time to withdrawal of care of non-surviving patients. We performed a retrospective study of patients resuscitated after cardiac arrest in two large academic community hospitals...

BACKGROUND The purpose of this study was to determine the effect of mild hypothermia therapy on gastric mucosa after cardiopulmonary resuscitation (CPR) and the underlying mechanism. MATERIAL AND METHODS Ventricular fibrillation was induced in pigs. After CPR, the surviving pigs were divided into mild hypothermia-treated and control groups. The changes in vital signs and hemodynamic parameters were monitored before cardiac arrest and at intervals of 0.5, 1, 2, 4, 6, 12, and 24 h after restoration of spontaneous circulation...

BACKGROUND/AIMS: Temperature control improves neurological prognosis in comatose cardiac arrest (CA) survivors. Previous reports demonstrate that most affected patients show signs of significant systemic inflammation. In an effort to better characterize potential temperature-related effects on key inflammatory pathways, we investigate the course of Tryptophan (Trp) levels, Tryptophan catabolites (including kynurenines) and indoleamine-2,3-dioxygenase (IDO)-activity in post CA patients...

BACKGROUND: Patients successfully resuscitated by paramedics from out-of-hospital cardiac arrest often have severe neurologic injury. Laboratory and observational clinical reports have suggested that induction of therapeutic hypothermia during cardiopulmonary resuscitation (CPR) may improve neurologic outcomes. One technique for induction of mild therapeutic hypothermia during CPR is a rapid infusion of large-volume cold crystalloid fluid. METHODS: In this multicenter, randomized, controlled trial we assigned adults with out-of-hospital cardiac arrest undergoing CPR to either a rapid intravenous infusion of up to 2 L of cold saline or standard care...

INTRODUCTION AND OBJECTIVES: Therapeutic hypothermia (TH) is recommended for patients with return of spontaneous circulation (ROSC) after cardiac arrest (CA). There is still uncertainty about management, target temperature and duration of TH. In the present study we aim to describe the initial experience of a non-tertiary care center with TH after CA and to determine predictors of mortality. METHODS: During the period 2011-2014, out of 2279 patients hospitalized in the intensive care unit, 82 had a diagnosis of CA with ROSC...

BACKGROUND: The early prediction of neurological outcomes in postcardiac arrest patients treated with therapeutic hypothermia (TH) remains challenging. Amplitude-integrated electroencephalography (aEEG) is a type of quantitative EEG. A particular cutoff time from the return of spontaneous circulation (ROSC) to the recovery of a normal aEEG trace for predicting a good neurological outcome has not yet been established. The purpose of the present study was to examine the relation between neurological outcomes and the continuous normal voltage (CNV) recovery time in adult comatose survivors of cardiac arrest treated with TH and identify the recovery time cutoff for predicting a good neurological outcome...

Therapeutic hypothermia is well known for its protective effect against brain injury after cardiac arrest, but the exact mechanism remains unclear. Cold-inducible RNA-binding protein (CIRP), a member of cold shock protein, enables mammalian cells to withstand decreased temperature by regulating gene translation. However, the role of CIRP in global cerebral ischemia after therapeutic hypothermia has not been clearly elucidated. In the present study, rats resuscitated from 4 min of cardiac arrest were separately treated with therapeutic hypothermia (immediately after return of spontaneous circulation (ROSC); targeted temperature at 33 °C) and therapeutic normothermia (targeted temperature at 36...

Old age is considered a negative prognostic factor after out-of-hospital cardiac arrest (OHCA). The purpose of this study was to assess the benefit of therapeutic hypothermia (TH) on survival and neurologic outcome in the elderly. This is a retrospective study of patients treated for OHCA from April 2011 to August 2013 in a regional cardiac system. Patients with return of spontaneous circulation (ROSC) are directed to designated cardiac receiving centers with established TH protocols. The decision to initiate TH is determined by the treating physician...

Many emergency physicians struggle with the clinical question of whether to perform therapeutic hypothermia (TH) or coronary angiography (CAG) first after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA). We analyzed the results of the SOS-KANTO 2012 study, which is a prospective, multicenter (67 emergency hospitals), observational study about OHCA conducted between January 2012 and March 2013 (n = 16,452). We compared two groups: the group in which TH was first performed (TH group), and the group in which CAG was performed first (CAG group) within 24 h after arrival...

INTRODUCTION: Due to limited resources, the 2010 European Resuscitation Council (ERC) guidelines could not be fully implemented in the Emergency Medical Services (EMS) of Brunswick, Germany. This is why implementation was prioritized according to local conditions. Thus, prehospital therapeutic hypothermia, mechanical chest compression and feedback systems were not established. Clinical data and long-term results were assessed by a QM system and room for improvement was identified. METHODS: All attempted resuscitations from 2011 until 2014 were recorded and compared against the German Resuscitation Registry...

AIMS: Heart rate variability (HRV) is a measure of the balance between the sympathetic and parasympathetic autonomic nervous system and lack thereof an ominous sign in many cardiac and neurological conditions including post-cardiac arrest syndrome. Whole body periodic acceleration (pGz) has been shown to be cardio protective when applied prior to during and after cardiac arrest (CA). Here, we investigate whether or not pGz pre or post treatment after CA preserves HRV. METHODS: Eight min of unsupported ventricular fibrillation followed by CPR and defibrillation was carried out in 32 anesthetized and paralyzed male swine who were randomized to pretreatment (1h pGz prior to CA, pre-pGz [n=8]) or post-treatment (pGz beginning at 30min after return of spontaneous circulation ([ROSC], post-pGz [n=8]) or none (CONT [n=8])...

AIMS: to explore the association between post return of spontaneous circulation (ROSC) hemoglobin level and survival with good neurological outcome following out-of-hospital cardiac arrest. METHODS: We studied adults with non-traumatic out-of-hospital cardiac arrest who achieved ROSC within 50min of collapse. We quantified the association between post ROSC hemoglobin level and good neurological outcome (defined as Cerebral Performance Category score of 1or 2), using multivariate logistic regression analyses...

REVIEW
Leah Bergman, Justin B Lundbye
Cardiac arrest (CA) often results in hemodynamic and metabolic compromise with associated poor prognosis. Therapeutic hypothermia (TH) has become the standard of care for CA survivors, decreasing reperfusion injury and intercellular acid-base disturbances, with improved neurologic outcomes. These benefits are realized despite a mild acidosis that can potentially occur during TH. By contrast, the severity of acidosis after return of spontaneous circulation (ROSC) must be monitored carefully and managed appropriately...

OBJECTIVES: Therapeutic hypothermia has been shown to improve neurologic outcome and survival in out-of-hospital cardiac arrest (OHCA) following return of spontaneous circulation (ROSC), and current guidelines recommend therapeutic hypothermia for all comatose survivors of OHCA. However, recommendations for nonshockable rhythms are not as strongly supported. Our study aims to provide further evidence on the use of therapeutic hypothermia in nonshockable rhythms. METHODS: A multivariate analysis with propensity score matching was performed using a cardiac arrest registry maintained by the Houston Fire Department...

BACKGROUND: Systemic hypertension and left ventricular hypertrophy (LVH) are major risk factors of cardiac arrest. However, the impacts of hypertension and LVH on the outcome of cardiopulmonary resuscitation (CPR) and post-resuscitation hypothermia are still undetermined. METHODS: After 4 min of untreated ventricular fibrillation (VF) and 4 min of CPR, defibrillation was attempted in 16 male spontaneously hypertensive rats (SHR) with LVH and 16 male normotensive Wistar Kyoto (WKY) rats...
