Background Oxygen plays a pivotal role in cardiopulmonary resuscitation (CPR) and postresuscitation intervention for cardiac arrest. However, the optimal method to reoxygenate patients has not been determined. This study investigated the effect of timing of hyperoxygenation on neurological outcomes in cardiac arrest/CPR rats treated with targeted temperature management. Methods and Results After induction of ventricular fibrillation, male Sprague‐Dawley rats were randomized into 4 groups (n=16/group): (1) normoxic control; (2) O 2 _CPR, ventilated with 100% O 2 during CPR; (3) O 2 _CPR+postresuscitation, ventilated with 100% O 2 during CPR and the first 3 hours of postresuscitation; and (4) O 2 _postresuscitation, ventilated with 100% O 2 during the first 3 hours of postresuscitation. Targeted temperature management was induced immediately after resuscitation and maintained for 3 hours in all animals. Postresuscitation hemodynamics, neurological recovery, and pathological analysis were assessed. Brain tissues of additional rats undergoing the same experimental procedure were harvested for ELISA‐based quantification assays of oxidative stress–related biomarkers and compared with the sham‐operated rats (n=6/group). We found that postresuscitation mean arterial pressure and quantitative electroencephalogram activity were significantly increased, whereas astroglial protein S100B, degenerated neurons, oxidative stress–related biomarkers, and neurologic deficit scores were significantly reduced in the O 2 _CPR+postresuscitation group compared with the normoxic control group. In addition, 96‐hour survival rates were significantly improved in all of the hyperoxygenation groups. Conclusions In this cardiac arrest/CPR rat model, hyperoxygenation coupled with targeted temperature management attenuates ischemia/reperfusion‐induced injuries and improves survival rates. The beneficial effects of high‐concentration oxygen are timing and duration dependent. Hyperoxygenation commenced with CPR, which improves outcomes when administered during hypothermia.

Purpose: Targeted temperature management (TTM) is a standard of care in patients after cardiac arrest for neuroprotection. Currently, the effectiveness and efficacy of TTM after extracorporeal cardiopulmonary resuscitation (ECPR) is unknown. We aimed to compare neurological and survival outcomes between TTM vs non-TTM in patients undergoing ECPR for refractory cardiac arrest. Methods: We searched PubMed and 5 other databases for randomized controlled trials and observational studies reporting neurological outcomes or survival in adult patients undergoing ECPR with or without TTM. Good neurological outcome was defined as cerebral performance category <3. Two independent reviewers extracted the data. Random-effects meta-analyses were used to pool data. Results: We included 35 studies (n = 2,643) with the median age of 56 years (interquartile range [IQR]: 52-59). The median time from collapse to ECMO cannulation was 58 minutes (IQR: 49-82) and the median ECMO duration was 3 days (IQR: 2.0-4.1). Of 2,643, 1,329 (50.3%) patients received TTM and 1,314 (49.7%) did not. There was no difference in the frequency of good neurological outcome at any time between TTM (29%, 95% confidence interval [CI]: 23%-36%) vs. without TTM (19%, 95% CI: 9%-31%) in patients with ECPR ( P = 0.09). Similarly, there was no difference in overall survival between patients with TTM (30%, 95% CI: 22%-39%) vs. without TTM (24%, 95% CI: 14%-34%) ( P = 0.31). A cumulative meta-analysis by publication year showed improved neurological and survival outcomes over time. Conclusions: Among ECPR patients, survival and neurological outcome were not different between those with TTM vs. without TTM. Our study suggests that neurological and survival outcome are improving over time as ECPR therapy is more widely used. Our results were limited by the heterogeneity of included studies and further research with granular temperature data is necessary to assess the benefit and risk of TTM in ECPR population.

This 2019 focused update to the American Heart Association pediatric advanced life support guidelines follows the 2018 and 2019 systematic reviews performed by the Pediatric Life Support Task Force of the International Liaison Committee on Resuscitation. It aligns with the continuous evidence review process of the International Liaison Committee on Resuscitation, with updates published when the International Liaison Committee on Resuscitation completes a literature review based on new published evidence. This update provides the evidence review and treatment recommendations for advanced airway management in pediatric cardiac arrest, extracorporeal cardiopulmonary resuscitation in pediatric cardiac arrest, and pediatric targeted temperature management during post–cardiac arrest care. The writing group analyzed the systematic reviews and the original research published for each of these topics. For airway management, the writing group concluded that it is reasonable to continue bag-mask ventilation (versus attempting an advanced airway such as endotracheal intubation) in patients with out-of-hospital cardiac arrest. When extracorporeal membrane oxygenation protocols and teams are readily available, extracorporeal cardiopulmonary resuscitation should be considered for patients with cardiac diagnoses and in-hospital cardiac arrest. Finally, it is reasonable to use targeted temperature management of 32°C to 34°C followed by 36°C to 37.5°C, or to use targeted temperature management of 36°C to 37.5°C, for pediatric patients who remain comatose after resuscitation from out-of-hospital cardiac arrest or in-hospital cardiac arrest.

Potential Benefits

Targeted temperature management (TTM), formerly known as therapeutic hypothermia, has been shown to improve survival and neurological recovery in patients following cardiac arrest. Following successes with its in-hospital implementation, many guidelines now advocate its use in the prehospital domain for all out-of-hospital cardiac arrests (OHCAs). It has been suggested that patients presenting with shockable rhythms who receive early initiation of TTM have better survival rates. TTM can be initiated in the prehospital setting with minimal equipment. This article discusses and explores the potential benefits and pitfalls of targeted temperature management when initiated in the prehospital environment. Particular focus is given to potential treatment strategies that can be used by paramedics to adequately manage OHCA. It is proposed that prehospital TTM is advantageous to all patients in cardiac arrest and can be efficacious in a variety of prehospital environments, with its implementation requiring only minimal equipment.

ABSTRACT Objective: to compare the rate of return of spontaneous circulation (ROSC) and death after cardiac arrest, with and without the use of a metronome during cardiopulmonary resuscitation (CPR). Method: case-control study nested in a cohort study including 285 adults who experienced cardiac arrest and received CPR in an emergency service. Data were collected using In-hospital Utstein Style. The control group (n=60) was selected by matching patients considering their neurological condition before cardiac arrest, the immediate cause, initial arrest rhythm, whether epinephrine was used, and the duration of CPR. The case group (n=51) received conventional CPR guided by a metronome set at 110 beats/min. Chi-square and likelihood ratio were used to compare ROSC rates considering p≤0.05. Results: ROSC occurred in 57.7% of the cases, though 92.8% of these patients died in the following 24 hours. No statistically significant difference was found between groups in regard to ROSC (p=0.2017) or the occurrence of death (p=0.8112). Conclusion: the outcomes of patients after cardiac arrest with and without the use of a metronome during CPR were similar and no differences were found between groups in regard to survival rates and ROSC.

Cardiac arrest is associated with high mortality if without early diagnosis and cardiopulmonary resuscitation. Each minute without emergency cardiopulmonary resuscitation (CPR), the patient’s chance of survival is reduced by ten percent, even if properly resuscitated but not recirculated, the chance of survival is reduced by four percent. Therefore, CPR should be ferformed as soon as patient is diagnosed with cardiac arrest with the signs of unconsciousness, apnea, loss of carotid pulse and inguinal pulse. Chest compression plays an important role in the success of CPR. There is emphasis on the characteristics of high-quality CPR: compressing the chest at an adequate rate and depth, allowing complete chest recoil after each compression, minimizing interruptions in compressions, and avoiding excessive ventilation. Emergency coronary angiography is recommended for all patients with ST elevation and for hemodynamically or electrically unstable patients without ST elevation for whom a cardiovascular lesion is suspected. All adult patients with return of spontaneous circulation after cardiac arrest should have targeted temperature management (TTM) to prevent poor neurologic outcome.

Introduction. Ischemia/Reperfusion (I/R) is a primary cause of myocardial injury after acute myocardial infarction resulting in the release of damage-associated molecular patterns (DAMPs), which can induce a sterile inflammatory response in the myocardial penumbra. Targeted temperature management (TTM) after I/R has been established for neuroprotection, but the cardioprotective effect remains to be elucidated. Therefore, we investigated the effect of TTM on cell viability, immune response, and DAMP release during oxygen-glucose deprivation/reperfusion (OGD/R) in murine primary cardiomyocytes. Methods. Primary cardiomyocytes from P1-3 mice were exposed to 2, 4, or 6 hours OGD (0.2% oxygen in medium without glucose and serum) followed by 6, 12, or 24 hours simulated reperfusion (21% oxygen in complete medium). TTM at 33.5°C was initiated intra-OGD, and a control group was maintained at 37°C normoxia. Necrosis was assessed by lactate dehydrogenase (LDH) release and apoptosis by caspase-3 activation. OGD-induced DAMP secretions were assessed by Western blotting. Inducible nitric oxide synthase (iNOS), cytokines, and antiapoptotic RBM3 and CIRBP gene expressions were measured by quantitative polymerase chain reaction. Results. Increasing duration of OGD resulted in a transition from apoptotic programmed cell death to necrosis, as observed by decreasing caspase-3 cleavage and increasing LDH release. DAMP release and iNOS expression correlated with increasing necrosis and were effectively attenuated by TTM initiated during OGD. Moreover, TTM induced expression of antiapoptotic RBM3 and CIRBP. Conclusion. TTM protects the myocardium by attenuating cardiomyocyte necrosis induced by OGD and caspase-3 activation, possibly via induction of antiapoptotic RBM3 and CIRBP expressions, during reperfusion. OGD induces increased Hsp70 and CIRBP releases, but HMGB-1 is the dominant mediator of inflammation secreted by cardiomyocytes after prolonged exposure. TTM has the potential to attenuate DAMP release.

Targeted temperature management and extracorporeal life support, particularly extracorporeal membrane oxygenation in patients undergoing cardiopulmonary resuscitation, represent outcome-enhancing strategies for patients following in- and out-of-hospital cardiac arrest. Although targeted temperature management with hypothermia between 32°C and 34°C and extracorporeal cardiopulmonary resuscitation bear separate potentials to improve outcome after out-of-hospital cardiac arrest, each is associated with bleeding risk and risk of infection. Whether the combination imposes excessive risk on patients is, however, unknown.

Hospital Cardiac Arrest

Sudden cardiac death, whether in the hospital or out of the hospital, is a leading cause of death. Early recognition and activation of an emergency response, following the “chain of survival”, is critical. High quality Cardiopulmonary Resuscitation (CPR) should be initiated as soon as possible. Rescue breaths can be added when a qualified medical professional is available. Once emergency medical services personnel arrive for an out of hospital cardiac arrest or the “code team” arrives for an in hospital cardiac arrest, the Advanced Cardiovascular Life Support (ACLS) algorithm should be followed. For patients with pulseless ventricular tachycardia or ventricular fibrillation, early defibrillation improves the chances for restoration of spontaneous circulation and survival. The use of vasopressors and anti-arrhythmics are part of the protocol, though the benefits are unclear. Once trained airway providers are available, placement of an advanced airway, either supraglottic or endotracheal, can be considered after several minutes of CPR-ACLS, though optimal timing and clear benefit have not been established. For patients who remain comatose after resuscitation, initiation of Targeted Temperature Management can improve outcomes. Neuroprognostication is complex and should be delayed for at least 3-5 days after resuscitation and should be based upon multiple sources of information. This review contains 1 figure, 5 tables, and 44 references.
