- The purpose of this studywas to investigate the prognostic value of lactate at admission, 12-h lactate and 12-h lactate clearance for 30-day survival in comatose patients admitted after out of hospi tal cardiac Arrest (OHCA). Although measures of lactate have been successfully implemented in sepsis and trauma care, most OHCA studies are biased due to design and the results are conflicting. This is a post hoc analysis of the TTM-Trial, a multicentre ran domized controlled trial investigating a temperature intervention of 33 C vs. 36 C after OHCA. 939 patients were analysed. 30-day survival was 56%. Median admission lactate was 6.0mmol/l [3.0-9.5]. Survivors at day 30 had lower admission lactate 4.7mmol/l [2.4-8.9] vs. 7.3mmol/l [4.5-10.7] for non-survivors, p < 0.01. The difference inmedian 12-h lactate was 1.4mmol/l [1.0-2.3] vs. 2.0mmol/l [1.2-3.3], p < 0.01. 12-h lactate clearance was 47±70% in survivors vs. 54±46%, p = 0.03. In a mixed model including all sample times, average lactate valueswere higher in the 33C-group (p < 0.001). In an unad justed model the odds ratio (OR) for death by 1mmol/l increase in lactate was 1.1 [1.1-1.2] at admission (p < 0.01), 1.2 [1.1-1.3] at 12-h (p < 0.01) and 1.003 [1.0-1.01] per % decrease in 12-h clear ance (p = 0.03). In a multivariate analysis, admission lactate and 12-h lactate remained independent predictors of 30-day mortality. A receiver operator curve illustrates the prognostic properties of different measures of lactate in this study. Admission lactate and 12-h lactate are associated with 30-day survival after cardiac arrest. The diagnostic value of these lactate measures is of limited use in clinical praxis.

- Introduction. According to the 2021 ERC/ESICM guideline recommen-dations, elevated neuron-specific enolase [NSE] levels as well as diffuseand extensive anoxic damage on neuroimaging are predictors of poorneurological outcome after cardiac arrest.(1) We previously describedthat NSE is elevated in patients with generalised oedema on com-puted tomography [CT]. (2).Objectives. In this study, we aim to examine the novel brain injurymarkers serum neurofilament light [NFL], glial fibrillary acidic protein[GFAP] and total-tau [tau] to predict the presence of generalised brainoedema.Methods. Retrospective analysis of patients examined with CT onclinical indication within the Target Temperature Management afterout-of-hospital cardiac arrest [TTM] trial. (2,3) Serum samples fromthe biobank sub study were prospectively collected at 48 h post arrestand analysed after trial completion as published. (4–7) The neuronalmarker NSE, the neuroaxonal injury markers NFL and tau and theastrocytic injury marker GFAP were correlated with the presence ofgeneralised oedema on CT, assessed by local radiologists through vis-ual evaluation. The prognostic accuracy of NSE ≥ 60 ug/l for predictinggeneralised oedema was also analysed.Results. 192 patients had data available on all four biomarkers at 48 hand were examined with CT < 168 h post arrest. Brain injury markerswere significantly higher in patients with generalised oedema as com-pared to patients without oedema on CT scans performed 24–168 hafter ROSC (p < 0.001) (Fig. 1A–D). For CT scans performed < 24 h, onlyNSE levels showed a significant correlation (p < 0.05). Biomarkers pre -dicted generalised oedema with area under the receiver operatingcharacteristics curve [AUC] 67.5–73.2% for CT scans performed < 24 h(n = 111), with no statistically significant difference between themarkers ( Fig. 2A). For scans performed 24–168 h (n = 81) AUC for pre -dicting generalised oedema was 78.1%-82.9%, with no statisticallysignificant difference between the markers. NSE ≥ 60 ug/l at 48 h, asrecommended by guidelines, predicted generalised oedema with 81%(95%CI 67–90%) sensitivity and 77% (95%CI 62–87%) specificity.Conclusion. Concentrations of all evaluated brain injury markerswere significantly higher in patients with generalised oedema on CTperformed after the first 24 h post arrest. Biomarker concentrationsindicate whether generalised oedema on CT is likely and may thus beclinically useful for deciding if a CT scan is sufficient for prognostica-tion or if a MRI is more appropriate.
