<h3>Importance</h3> Extracorporeal cardiopulmonary resuscitation (ECPR) is expected to improve the neurological outcomes of patients with refractory cardiac arrest; however, it invasive, expensive, and requires substantial human resources. The ability predict would assist in patient selection for ECPR. <h3>Objective</h3> To develop validate a prediction model out-of-hospital arrest shockable rhythm treated <h3>Design, Setting, Participants</h3> This prognostic study analyzed data from...
<title>Abstract</title> Background Cardiac arrest leads to an abrupt cessation of blood flow, resulting in severe metabolic acidosis. Base excess (BE) is a widely used marker However, its prognostic value cardiac patients remains unclear, as previous studies have not adjusted for the time from testing. This study aimed assess association between BE levels and neurological outcomes with out-of-hospital (OHCA) by adjusting onset tests. Methods Osaka, Japan, enrolled consecutive OHCA...
We aimed to identify the association of pH value in blood gas assessment with neurological outcome among out-of-hospital cardiac arrest (OHCA) patients treated by extracorporeal cardiopulmonary resuscitation (ECPR).We retrospectively analyzed database a multicenter prospective observational study on OHCA Osaka prefecture, Japan (CRITICAL study), from July 1, 2012 December 31, 2016. included adult ECPR. Patients external causes such as trauma were excluded. conducted logistic regression...
We established a multi-center, prospective cohort that could provide appropriate therapeutic strategies such as criteria for the introduction and effectiveness of in-hospital advanced treatments, including percutaneous coronary intervention (PCI), target temperature management, extracorporeal cardiopulmonary resuscitation (ECPR) out-of-hospital cardiac arrest (OHCA) patients.In Osaka Prefecture, Japan, we registered all consecutive patients who were suffering from an OHCA whom was attempted...
Abstract We aimed to investigate the association between serum lactate levels during cardiopulmonary resuscitation (CPR) and survival in patients with out-of-hospital cardiac arrest (OHCA). From database of a multicenter registry on OHCA patients, we included adult nontraumatic transported hospital ongoing CPR. Based CPR, were divided into four quartiles: Q1 (≤ 10.6 mEq/L), Q2 (10.6–14.1 Q3 (14.1–18.0 Q4 (> 18.0 mEq/L). The primary outcome was 1-month survival. Among 5226 eligible group...
Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) has been proposed as a rescue therapy for patients with refractory cardiac arrest. This study aimed to evaluate the association between ECPR and clinical outcomes among out-of-hospital arrest (OHCA) using risk-set matching time-dependent propensity score. Methods was secondary analysis of JAAM-OHCA registry data, nationwide multicenter prospective OHCA, from June 2014 December 2019, that included adults (≥ 18 years)...
Background Few prediction models for individuals with early‐stage out‐of‐hospital cardiac arrest (OHCA) have undergone external validation. This study aimed to externally validate updated OHCA outcomes using a large nationwide dataset. Methods and Results We performed secondary analysis of the JAAM‐OHCA (Comprehensive Registry In‐Hospital Intensive Care Out‐of‐Hospital Cardiac Arrest Survival Japanese Association Acute Medicine Arrest) registry. Previously developed patients who achieved...
Background: Little is known about the association between serum potassium level on hospital arrival and neurological outcome after out-of-hospital cardiac arrest (OHCA). We investigated whether had prognostic indications for patients with OHCA. Methods: This prospective, multicenter observational study conducted in Osaka, Japan (CRITICAL study) enrolled consecutive OHCA transported to 14 participating institutions from 2012 2016. included adult aged ⩾18 years of origin who achieved return...
Background:The hypothesis of this study is that latent class analysis could identify the subphenotypes out-of-hospital cardiac arrest (OHCA) patients associated with outcomes and allow us to explore heterogeneity in effects extracorporeal cardiopulmonary resuscitation (ECPR).
Abstract Background Singapore and Osaka in Japan have comparable population sizes prehospital management; however, the frequency of ECPR differs greatly for out-of-hospital cardiac arrest (OHCA) patients with initial shockable rhythm. Given this disparity, we hypothesized that outcomes among OHCA rhythm were different from those Osaka. The aim study was to evaluate compared expected derived data using machine learning-based prediction models. Methods This a secondary analysis two databases:...
The effect of post-cardiac arrest care in children with out-of-hospital cardiac (OHCA) has not been adequately established, and the long-term outcome after pediatric OHCA sufficiently investigated. We describe here detailed in-hospital characteristics, actual management, survival, including neurological status, 90 days occurrence transported to critical medical centers (CCMCs).
We aimed to identify subphenotypes among patients with out-of-hospital cardiac arrest (OHCA) initial non-shockable rhythm by applying machine learning latent class analysis and examining the associations between neurological outcomes.This study was a retrospective within multi-institutional prospective observational cohort of OHCA in Osaka, Japan (the CRITICAL study). The data adult medical causes presenting 2012 2016 were included models, which identified subphenotypes, who presented 2017...
A 72-year-old man presented with severe pulmonary contusions and multiple traumas, including aortic injury, pelvic fracture, renal injury. The patient required multidisciplinary treatment, transcatheter arterial embolization, thoracic endovascular repair, right lung upper lobe partial resection, massive transfusion. During the initial experienced respiratory failure due to endotracheal bleeding, we attempted isolated ventilation a 37 Fr double-lumen intubation tube. Although drainage by...
The effectiveness of IABP for shockable out-of-hospital cardiac arrest (OHCA) has not been extensively investigated. This study aimed to investigate whether the use an intra-aortic balloon pump (IABP) non-traumatic OHCA patients was associated with favorable neurological outcomes. From Japanese Association Acute Medicine Out-of-Hospital Cardiac Arrest registry, a nationwide multicenter prospective we enrolled adult and whom resuscitation attempted, who were transported participating...
Abstract Background The association between spontaneous initial body temperature on hospital arrival and neurological outcomes has not been sufficiently studied in patients after out-of-hospital cardiac arrest (OHCA). Methods From the prospective database of Comprehensive Registry Intensive Care for OHCA Survival (CRITICAL) study Osaka, Japan, we enrolled all with medical origin aged > 18 years whom resuscitation was attempted who were transported to participating hospitals 2012 2019. We...
There is limited information on the predictive accuracy of commonly used predictors, such as lactate, pH or serum potassium for survival among out-of-hospital cardiac arrest (OHCA) patients with hypothermia. This study aimed to identify these biomarkers OHCA In this retrospective analysis, we analyzed data from a multicenter, prospective nationwide registry transported emergency departments in Japan (the JAAM-OHCA Registry). We included all adult (≥18 years) hypothermia (≤32.0 °C) who were...
