AbstractPrognostication after cardiopulmonary resuscitation (CPR) is complex. Novel biomarkers like soluble suppression of tumorigenicity 2 (sST2) may provide an objective approach. A total of 106 post-CPR patients were included in this single-center observational prospective study. Serum sST2 levels were obtained 24 h after admission. Individuals were assigned to two groups: patients below and above the overall cohort’s median sST2 concentration. Primary outcome was a combined endpoint at 6 months (death or Cerebral Performance Category > 2); secondary endpoint 30-day mortality. A uni- and multivariate logistic regression analysis were conducted. Elevated sST2-levels were associated with an increased risk for the primary outcome (OR 1.011, 95% CI 1.004–1.019, p = 0.004), yet no patients with poor neurological outcome were observed at 6 months. The optimal empirical cut-off for sST2 was 46.15 ng/ml (sensitivity 81%, specificity 53%, AUC 0.69). Levels above the median (> 53.42 ng/ml) were associated with higher odds for both endpoints (death or CPC > 2 after 6 months: 21% vs. 49%, OR 3.59, 95% CI 1.53–8.45, p = 0.003; death after 30 days: 17% vs. 43.3%, OR 3.75, 95% CI 1.52–9.21, p = 0.003). A positive correlation of serum sST2 after CPR with mortality at 30 days and 6 months after cardiac arrest could be demonstrated.

Abstract We aimed to estimate the association between PaCO2 level in the patient after out-of-hospital cardiac arrest (OHCA) resuscitation with patient outcome based on a multicenter prospective cohort registry in Japan between June 2014 and December 2015.Based on the PaCO2 within 24-h after return of spontaneous circulation (ROSC), patients were divided into six groups as follow; severe hypocapnia (<25mmHg), mild hypocapnia (25–35mmHg,), normocapnia (35–45mmHg), mild hypercapnia (45–55mmHg), severe hypercapnia (>55mmHg), exposure to both hypocapnia and hypercapnia. Multivariate logistic regression analysis was conducted to calculate the adjusted odds ratios (aORs) and 95% confidence interval (CI) for the 1-month poor neurological outcome (Cerebral Performance Category ≥3). Among the 13491 OHCA patients, 607 were included. Severe hypocapnia, mild hypocapnia, severe hypercapnia, and exposure to both hypocapnia and hypercapnia were associated with a higher rate of 1-month poor neurological outcome compared with mild hypercapnia (aOR 6.68 [95% CI 2.16–20.67], 2.56 [1.30–5.04], 2.62 [1.06–6.47], 5.63 [2.21–14.34]; respectively). There was no significant difference between the outcome of patients with normocapnia and mild hypercapnia. In conclusion, maintaining normocapnia and mild hypercapnia during the 24-h after ROSC was associated with better neurological outcomes than other PaCO2 abnormalities in this study.

Abstract Background Cardiopulmonary resuscitation (CPR) manoeuvres involve vigorous compressions with the proper depth and rate in order to keep sufficient perfusion to organs, especially the brain. Accordingly, high incidences of CPR-related injuries (CPR-RI) have been observed in survivors after cardiac arrest (CA). Purpose To analyse whether CPR-related injuries have an impact on the survival and neurological outcomes of comatose survivors after CA. Methods Observational prospective database of consecutive patients (pts) admitted to the acute cardiac care unit of a tertiary university hospital after in-hospital and out-of-hospital CA (IHCA and OHCA) treated with targeted temperature management (TTM 32–34°) from August 2006 to December 2019. CPR-RI were diagnosed by reviewing medical records and analysing image studies during hospitalization. Results A total of 498 pts were included; mean age was 62.7±14.5 years and 393 (78.9%) were men. We found a total of 145 CPR-RI in 109 (21.9%) pts: 79 rib fractures, 20 sternal fractures, 5 hepatic, 5 gastrointestinal, 3 spleen, 1 kidney, 26 lung and 6 heart injuries. Demographic characteristics and cardiovascular risk factors did not differ between the non-CPR-RI group and CPR-RI group. Also, we did not find differences in CA features (Table 1). Survival at discharge was higher in the CPR-RI group [74 (67.8%) vs 188 (48.3%); p&lt;0.001]. Moreover, Cerebral Performance Category (CPC) 1–2 within a 3-month follow-up was significantly higher in the CPR-RI group [(71 (65.1%) vs 168 (43.2%); p&lt;0.001; Figure 1]. Finally, pts who recieved blood transfusions were proportionally higher in the CPR-RI group [34 (32.1%) vs 65 (16.7%)]; p=0.004). Conclusions In our cohort, the presence of CPR-RI was associated with higher survival at discharge and better neurological outcomes during follow-up.

ObjectiveTo study the prognostic significance of multiple novel biomarkers in combination after ischemic stroke.MethodsWe derived data from the China Antihypertensive Trial in Acute Ischemic Stroke, and 12 informative biomarkers were measured. The primary outcome was the combination of death and major disability (modified Rankin Scale score ≥3) at 3 months after ischemic stroke, and secondary outcomes included major disability, death, and vascular events.ResultsIn 3,405 participants, 866 participants (25.4%) experienced major disability or died within 3 months. In multivariable analyses, elevated high-sensitive C-reactive protein, complement C3, matrix metalloproteinase-9, hepatocyte growth factor, and antiphosphatidylserine antibodies were individually associated with the primary outcome. Participants with a larger number of elevated biomarkers had increased risk of all study outcomes. The adjusted odds ratios (95% confidence intervals) of participants with 5 elevated biomarkers were 3.88 (2.05–7.36) for the primary outcome, 2.81 (1.49–5.33) for major disability, 5.67 (1.09–29.52) for death, and 4.00 (1.22–13.14) for vascular events, compared to those with no elevated biomarkers. Simultaneously adding these 5 biomarkers to the basic model with traditional risk factors led to substantial reclassification for the combined outcome (net reclassification improvement 28.5%, p < 0.001; integrated discrimination improvement 2.2%, p < 0.001) and vascular events (net reclassification improvement 37.0%, p = 0.001; integrated discrimination improvement 0.8%, p = 0.001).ConclusionWe observed a clear gradient relationship between the numbers of elevated novel biomarkers and risk of major disability, mortality, and vascular events. Incorporation of a combination of multiple biomarkers observed substantially improved the risk stratification for adverse outcomes in ischemic stroke patients.

AimsThe purpose of this study was to develop a practical risk−score to predict poor neurological outcome after out−of−hospital cardiac arrest (OOHCA) for use on arrival to a Heart Attack Centre.Methods and ResultsBetween May 2012 and December 2017, 1055 patients had OOHCA in our region, of whom 373 patients were included in the King's Out of Hospital Cardiac Arrest Registry (KOCAR). We performed prediction modelling with multi-variable logistic regression to identify factors independently predictive of the primary outcome in order to derive a risk score. This was externally validated in two independent cohorts comprising 474 patients. The primary outcome was poor neurological function at 6−month follow−up (Cerebral Performance Category 3-−). Seven independent variables for prediction of outcome were identified: Missed (Unwitnessed) arrest, Initial non-shockable rhythm, non-Reactivity of pupils, Age, Changing intra-arrest rhythms, Low pH<;7.20 and Epinephrine administration. From these variables, the MIRA2CLE2 score was developed which had an AUC of 0.90 in the development and 0.85 and 0.89 in the validation cohorts. 3 risk groups of the MIRA2CLE2 were defined − Low risk (≤2−5.6% risk of poor outcome; Intermediate risk (3−4−55.4% of poor outcome) and high risk (≥5−92.3% risk of poor outcome). The risk-score performance was equivalent in a sub-group of patients referred for early angiography and revascularisation where appropriate.ConclusionsThe MIRA2CLE2 score is a practical risk score for early accurate prediction of poor neurological outcome after OOHCA, which has been developed for simplicity of use on admission to a Heart Attack Centre.

Object Intracranial tumors are common pediatric neoplasms and account for substantial morbidity among children with cancer. Hyponatremia is a known complication of neurosurgical procedures and is associated with higher morbidity among neurosurgical patients. The authors aimed to estimate the incidence of hyponatremia, identify clinical characteristics associated with hyponatremia, and assess the association between hyponatremia and patient outcome among children undergoing surgery for intracranial tumors. Methods This is a retrospective cohort study of children ranging in age from 0 to 19 years who underwent an initial neurosurgical procedure for an intracranial tumor between January 2001 and February 2012. Hyponatremia was defined as serum sodium ≤ 130 mEq/L during admission. Results Hyponatremia during admission occurred in 39 (12%) of 319 patients and was associated with young age and obstructive hydrocephalus (relative risk [RR] 2.9 [95% CI 1.3–6.3]). Hyponatremic patients were frequently symptomatic; 21% had seizures and 41% had altered mental status. Hyponatremia was associated with complicated care including mechanical ventilation (RR 4.4 [95% CI 2.5–7.9]), physical therapy (RR 4 [95% CI 1.8–8.8]), supplemental nutrition (RR 5.7 [95% CI 3.3–9.8]), and infection (RR 5.7 [95% CI 3.3–9.5]). Hyponatremic patients had a 5-fold increased risk of moderate or severe disability on the basis of their Pediatric Cerebral Performance Category score at discharge (RR 5.3 [95% CI 2.9–9.8]). Obstructive hydrocephalus (adjusted odds ratio [aOR] 3.24 [95% CI 1.38–8.94]) and young age (aOR 0.92 [95% CI 0.85–0.99]) were independently associated with hyponatremia during admission. Hyponatremia was independently associated with moderate or worse disability by Pediatric Cerebral Performance Category score at discharge (aOR 6.2 [95% CI 3.0–13.03]). Conclusions Hyponatremia was common, particularly among younger children and those with hydrocephalus. Hyponatremia was frequently symptomatic and was associated with more complicated hospital courses. Hyponatremia was independently associated with worse neurological outcome when adjusted for age and tumor factors. This study serves as an exploratory analysis identifying important risk factors for hyponatremia and associated sequelae. Further research into the causes of hyponatremia and the association with poor outcome is needed to determine if prevention and treatment of hyponatremia can improve outcomes in these children.

Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) has been reported to be effective in out-of-hospital cardiac arrest (OHCA) patients in whom ventricular fibrillation (VF) as an initial rhythm were refractory to conventional cardiopulmonary resuscitation (CPR). However, it remains unclear whether ECPR is effective even though cardiac rhythm would change from VF to non-VF during CPR. Methods: This multicenter prospective observational study was conducted in 46 hospitals. A total of 457 patients with OHCA aged 20-74 years in whom initial rhythm was VF and the duration from collapse to hospital arrival was within 45 minutes were originally registered. After given CPR for more than 15 minutes in hospital, these patients received combination therapy with ECPR including therapeutic hypothermia (TH), or not received. The patients underwent ECPR (n=250) were classified into the following 2 groups according to rhythm changes during CPR; Group-A (sustained VF; n=127) and Group-B (changing from VF initially to non-shockable rhythm; n=123). The endpoint was a favorable outcome defined as Cerebral Performance Category 1-2 at 6 months after collapse. Results: There were no significant differences of age, sex, time from collapse to ECPR start and the rate of TH between the 2 groups. The rate achieving favorable outcome was significantly higher in Group-A than Group-B. (19.7% vs. 3.3%, p<0.001) (Figure1). When focusing on sustained VF (Group-A), the rate achieving favorable outcome improved about 5.5-fold by ECPR (ECPR, n=127; 19.7% vs. non-ECPR, n=55; 3.6%, p<0.001) (Figure2). In the multivariate logistic-regression analysis, sustained VF during CPR was the strongest predictor for the favorable outcomes among the pre-hospital parameters including age, bystander CPR and time from collapse to ECPR (Odds ratio 4.43, p=0.018). Conclusions: These findings indicates that the patients with sustained VF seem to be a particular population that could merit ECPR.

ObjectiveTo compare resuscitation outcomes before and after switching from manual cardiopulmonary resuscitation (CPR) to load-distributing band (LDB) CPR in a multi-center Emergency Departments (ED) trial.MethodsThis is a phased, prospective cohort evaluation with intention-to-treat analysis of adults with non-traumatic cardiac arrest. The intervention is change in the system from manual CPR to LDB-CPR at two Urban EDs. The main outcome measure is survival to hospital discharge, with secondary outcome measures of return of spontaneous circulation (ROSC), survival to hospital admission and neurological outcome at discharge.ResultsA total of 1,011 patients were included in the study, with 459 in the manual CPR phase (January 01, 2004, to August 24, 2007) and 552 patients in the LDB-CPR phase (August 16, 2007, to December 31, 2009). In the LDB phase, the LDB device was applied in 454 patients (82.3%). Patients in the manual CPR and LDB-CPR phases were comparable for mean age, gender and ethnicity. Rates for ROSC were comparable with LDB-CPR (manual 22.4% vs. LDB 35.3%; adjusted odds ratio [OR], 1.07; 95% confidence interval [CI], 0.63-1.83). Survival to hospital admission was increased, Manual 14.2% vs. LDB 19.7%; adjusted OR, 2.50; 95% CI, 1.05-6.00. Survival to hospital discharge was increased Manual 1.3% vs. LDB 3.3%; adjusted OR, 3.99; 95% CI, 1.06-15.02. The number of survivors with Cerebral Performance Category 1 (good) (Manual 1 vs. LDB 12, p < 0.01) and Overall Performance Category 1 (good) (Manual 1 vs. LDB 10, p < 0.01) was also increased. The Number Needed to Treat (NNT) for 1 survivor was 52 (95% CI, 26-1000).ConclusionA resuscitation strategy using LDB-CPR in an ED environment was associated with improved survival to admission and discharge in adults with non-traumatic cardiac arrest.

Purpose. Postresuscitation neuroprognostication is guided by neurophysiological tests, biomarker measurement, and clinical examination. Recent investigations suggest that circulating microRNAs (miRNA) may help in outcome prediction after cardiac arrest. We assessed the ability of miR-574-5p to predict neurological outcome after cardiac arrest, in a sex-specific manner. Methods. In this substudy of the Target Temperature Management (TTM) Trial, we enrolled 590 cardiac arrest patients for which blood samples were available. Expression levels of miR-574-5p were measured by quantitative PCR in plasma samples collected 48 h after cardiac arrest. The endpoint of the study was poor neurological outcome at 6 months (cerebral performance category scores 3 to 5). Results. Eighty-one percent of patients were men, and 49% had a poor neurological outcome. Circulating levels of miR-574-5p at 48 h were higher in patients with a poor neurological outcome at 6 months (p<0.001), both in women and in men. Circulating levels of miR-574-5p were univariate predictors of neurological outcome (odds ratio (OR) [95% confidence interval (CI)]: 1.5 [1.26-1.78]). After adjustment with clinical variables and NSE, circulating levels of miR-574-5p predicted neurological outcome in women (OR [95% CI]: 1.9 [1.09-3.45]), but not in men (OR [95% CI]: 1.0 [0.74-1.28]). Conclusion. miR-574-5p is associated with neurological outcome after cardiac arrest in women.

Central Cannulation

Introduction: Favorable survivorship after pediatric extracorporeal cardiopulmonary resuscitation (ECPR) may be limited by prolonged resuscitations. Surgical cannulation metrics for pediatric ECPR have not been widely reported by centers that use time interval benchmarks with a cardiovascular service responding to different hospital locations. Hypothesis: We hypothesize that survival is associated with resuscitation duration, and cannulation duration differs between peripheral and central approaches. Methods: This was a single-center retrospective study of patients 0-18 years with in-hospital ECPR between January 2015 and December 2020. Primary outcome was survival to hospital discharge. Secondary outcomes were odds of favorable neurologic outcome (dichotomized pediatric cerebral performance category), total resuscitation duration defined as cardiac arrest start to ECMO flow start (CA-ECMO), and cannulation duration. Non-parametric and regression methods were used. Results: Of the 92 events that met ECPR criteria, median weight and age were 4 months (IQR 1 month, 16 years) and 4.4 kg (range 1.9-133 kg). Cannulation occurred in the cardiac intensive care unit (ICU) (66%, 61 of 92), followed by operating room (13%, 12 of 92), pediatric ICU (12%, 11 of 92), and catheterization lab (9%, 8 of 92). Central cannulation was performed in 43% (40 of 92), and 21% (19 of 92) had open chests at the time of the event. Median duration of CA-ECMO was 35 min (IQR 26, 45 min); cannulation duration was 11 min (IQR 5, 16.5 min) for central compared to 18.5 min (IQR 12, 23 min) for peripheral approaches (P=0.01). Survival was 40% (37 of 92), and favorable neurologic outcome occurred in 38% (35 of 92). Survival (adjusted OR, 0.94; 95% CI 0.91-0.99, P=0.018) and favorable neurologic outcome (adjusted OR, 0.95; 95% CI 0.917-1.000, P=0.053) were associated with CA-ECMO duration after adjusting for cannulation approach, location, difficulty, shockable rhythm, and weight. Conclusion: In pediatric in-hospital ECPR, total CA-ECMO duration remains a key metric associated with patient outcomes. Central cannulation is faster than peripheral approaches. Since cannulation strategy alters CPR maneuvers, CPR effectiveness with each approach needs further study.
