BACKGROUND: In the chain of survival for Out-of-hospital cardiac arrest (OHCA), each component of care contributes to improve the prognosis of the patient with OHCA. The SARS-CoV-2 (COVID-19) pandemic potentially affected each part of care in the chain of survival. The aim of this study was to compare prehospital care, in-hospital treatment, and outcomes among OHCA patients before and after the COVID-19 pandemic. METHODS: We analyzed data from a multicenter prospective study in Kanto area, Japan, named SOS-KANTO 2017...

OBJECTIVE: In this paper, we present a comprehensive overview of our experience in establishing and leading distinct extracorporeal cardiopulmonary resuscitation (ECPR)-related teams to independently handle ECPR in the early stages in the emergency department. METHODS: A retrospective analysis was conducted on the clinical data of 29 patients who underwent ECPR treatment in the emergency room between May 2018 and April 2022. A control group, consisting of 10 patients treated between May 2018 and September 2019 was managed using a standard rescue coordination mode...

Prolonged cerebral hypoperfusion after the return of spontaneous circulation (ROSC) from cardiac arrest (CA) may lead to poor neurological recovery. In a 7-min asphyxia-induced CA rat model, four combinations of inhaled oxygen (iO2 ) and carbon dioxide (iCO2 ) were administered for 150 min post-ROSC and compared in a randomized animal trial. At the end of administration, the partial pressure of brain tissue oxygenation (PbtO2 ) monitored in the hippocampal CA1 region returned to the baseline for the 88% iO2 [ΔPbtO2 , median: -0...

OBJECTIVES: To determine if near-infrared spectroscopy measuring cerebral regional oxygen saturation (crSo2) during cardiopulmonary resuscitation is associated with return of spontaneous circulation (ROSC) and survival to hospital discharge (SHD) in children. DESIGN: Multicenter, observational study. SETTING: Three hospitals in the pediatric Resuscitation Quality (pediRES-Q) collaborative from 2015 to 2022. PATIENTS: Children younger than 18 years, gestational age 37 weeks old or older with in-hospital cardiac arrest (IHCA) receiving cardiopulmonary resuscitation greater than or equal to 1 minute and intra-arrest crSo2 monitoring...

INTRODUCTION: Growing evidence supports extracorporeal cardiopulmonary resuscitation (ECPR) for refractory out-of-hospital cardiac arrest (OHCA) patients, especially in experienced centres. We present characteristics, treatments, and outcomes of patients treated with ECPR in a high-volume cardiac arrest centre in the metropolitan area of Milan, Italy and determine prognostic factors. METHODS: Refractory OHCA patients treated with ECPR between 2013 and 2022 at IRCCS San Raffaele Scientific Institute in Milan had survival and neurological outcome assessed at hospital discharge...

Out-of-hospital cardiac arrest is a leading cause of death, accounting for ≈50% of all cardiovascular deaths. The prognosis of such individuals is poor, with <10% surviving to hospital discharge. Survival with a favorable neurologic outcome is highest among individuals who present with a witnessed shockable rhythm, received bystander cardiopulmonary resuscitation, achieve return of spontaneous circulation within 15 minutes of arrest, and have evidence of ST-segment elevation on initial ECG after return of spontaneous circulation...

BACKGROUND: Brain injury is a leading cause of morbidity and mortality in patients resuscitated from cardiac arrest. Mitochondrial dysfunction contributes to brain injury following cardiac arrest; therefore, therapies that limit mitochondrial dysfunction have the potential to improve neurological outcomes. Generation of reactive oxygen species (ROS) during ischemia-reperfusion injury in the brain is a critical component of mitochondrial injury and is dependent on hyperactivation of mitochondria following resuscitation...

INTRODUCTION: Survival from refractory out of hospital cardiac arrest (OHCA) without timely return of spontaneous circulation (ROSC) utilising conventional advanced cardiac life support (ACLS) therapies is dismal. CHEER3 was a safety and feasibility study of pre-hospital deployed extracorporeal membrane oxygenation (ECMO) during cardiopulmonary resuscitation (ECPR) for refractory OHCA in metropolitan Australia. METHODS: This was a single jurisdiction, single-arm feasibility study...

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) remains a frequent medical emergency with low survival rates even after a return of spontaneous circulation (ROSC). Growing evidence supports formation of dedicated teams in scenarios like cardiogenic shock to improve prognosis. Thus, the European Resuscitation Council (ERC) recommended introduction of Cardiac Arrest Centers (CAC) in their 2015 guidelines. Here, we aimed to elucidate the effects of newly introduced CACs in Germany regarding survival rate and neurological outcome...

OBJECTIVES: to map the scientific evidence on the use of abdominal compressions during cardiopulmonary resuscitation in patients with cardiac arrest. METHODS: this is a scoping review based on the question: "What is the evidence regarding the use of abdominal compressions during cardiopulmonary resuscitation in patients with cardiac arrest?". Publications up to August 2022 were collected from eight databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews was used...

OBJECTIVE: This study aimed to determine whether ultra-low tidal volume ventilation (ULTVV) applied during cardiopulmonary resuscitation (CPR) compared with standard ventilation (intermittent positive pressure ventilation, IPPV) can reduce pulmonary end-organ damage in the post-resuscitation period. METHODS: A prospective, randomized trial was conducted using a porcine model (n = 45). The animals were divided into three groups: IPPV, ULTVV, and a sham control group...

BACKGROUND: Although neonatal Staphylococcus aureus pneumonia is common and usually curable, it can also be refractory and life-threatening. Herein, we report a case of severe neonatal community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) necrotizing pneumonia with bilateral recurrent pyopneumothorax, respiratory failure, heart failure, and cardiac arrest. We hope our report will add to the understanding of this disease. CASE SUMMARY: An 18-d-old boy presented with cough for five days, fever for three days, and dyspnea for two days...

BACKGROUND: Our previous research proved that vagus nerve stimulation (VNS) improved the neurological outcome after cardiopulmonary resuscitation (CPR) by activating α7 nicotinic acetylcholine receptor (α7nAChR) in a rat model, but the underlying mechanism of VNS in neuroprotection after CPR remains unclear. METHODS: In vivo , we established a mouse model of cardiac arrest (CA)/CPR to observe the survival rate, and the changes in inflammatory factors and brain tissue after VNS treatment...

Extracorporeal Membrane Oxygenation Cardiopulmonary Resuscitation (ECPR) is the act of placing a patient on bypass at the bedside while simultaneously carrying out life-sustaining interventions such as chest compressions or epinephrine administration. This involves a team of physicians, nurses, respiratory therapists, pharmacists, extracorporeal membrane oxygenation (ECMO) trained staff, and other health professionals who must focus on cardiopulmonary resuscitation (CPR), cannulation, and initiating ECMO flow at the same time...

BACKGROUND: Evidence for extracorporeal cardiopulmonary resuscitation (CPR) in refractory out-of-hospital cardiac arrest (OHCA) remains inconclusive. Recently, the INCEPTION-trial, comparing extracorporeal with conventional CPR, found no statistically significant difference in neurologically favorable survival. Since protocol deviations were anticipated, a pre-specified per-protocol analysis was foreseen. METHODS: The per-protocol analysis of the INCEPTION trial excluded patients not meeting inclusion or exclusion criteria, amongst which time-to-cannulation of >60 minutes, and achieving a return of spontaneous circulation before hospital arrival...

OBJECTIVE: This study aims to evaluate the characteristics and outcomes of patients who fulfilled extracorporeal membrane oxygenation cardiopulmonary resuscitation (E-CPR) selection criteria during in-hospital cardiac arrest (IHCA). DESIGN: This is a nested cohort study. SETTING: Code blue data were collected across seven hospitals in Australia between July 2017 and August 2018. PARTICIPANTS: Participants who fulfilled E-CPR selection criteria during IHCA were included...

BACKGROUND: The effect of conservative vs. liberal oxygen therapy on outcomes of intensive care unit (ICU) patients with hypoxic ischaemic encephalopathy (HIE) is uncertain and will be evaluated in the Low Oxygen Intervention for Cardiac Arrest injury Limitation (LOGICAL) trial. OBJECTIVE: The objective of this study was to summarise the protocol and statistical analysis plans for the LOGICAL trial. DESIGN SETTING AND PARTICIPANTS: LOGICAL is a randomised clinical trial in adults in the ICU who are comatose with suspected HIE (i...

BACKGROUND: Refractory Out of Hospital Cardiac Arrest (r-OHCA) is common and the benefit versus harm of intra-arrest transport of patients to hospital is not clear. OBJECTIVE: To assess the rate of survival to hospital discharge in adult patients with r-OHCA, initial rhythm pulseless ventricular tachycardia (VT)/ventricular fibrillation (VF) or Pulseless Electrical Activity (PEA) treated with 1 of 2 locally accepted standards of care:1 expedited transport from scene; or2 ongoing advanced life support (ALS) resuscitation on-scene...
