Introduction: Prolonged time to Return of Spontaneous Circulation (ttROSC) after Out of Hospital Cardiac Arrest (OHCA) has consistently been associated with adverse outcome by a plausible direct relation to severity of anoxic injury. Hypothesis: Target temperature management (TTM) is assumed effective against anoxic brain injury and we hypothesized that TTM at 33 degrees would be more beneficial with prolonged time to ROSC compared to 36 degrees. Methods: In a post hoc analysis of the TTM trial, which showed no overall benefit of targeting 33 °C over 36 in 939 patients (NEJM 2013), we investigated the relation of time to ROSC and mortality and neurological outcome as assessed by the Cerebral Performance Category (CPC) and Modified Ranking Scale (mRS) after 180 days. Results: Prolonged ttROSC was significantly and independently associated with increased mortality, p<0.001 (figure), with Hazard Ratio (HR) of 1.02 (95% CI 1.01-1.02, p<0.001) per minute increase and level of TTM did not modify this association, p interaction =0.85. In survivors prolonged ttROSC was associated with increased odds of surviving with an unfavorable neurological outcome for CPC (p=0.008 for CPC 3-4) and a similar trend, albeit not statistically significant was observed for mRS (p=0.17, mRS 4-5). Odds for unfavorable neurological outcome (CPC>2, mRS>3) was not modified by levels of TTM overall. Conclusion: Time to ROSC remains a significant prognostic factor in comatose patients resuscitated from OHCA with regards to risk of death and risk of adverse neurological outcome in survivors. TTM at 33 degrees offers no advantage over targeting 36 degrees with regards to mortality or neurological outcome in patients with prolonged time to ROSC. Figure: Mortality rates stratified by quartiles of tome to ROSC and by TTM level. Differences tested by log rank test in between TTM in strata

Introduction: Targeted temperature management (TTM) has established evidence for improving neurological outcomes in cardiac arrest patients who sustained coma after return of spontaneous circulation (ROSC). The target temperature has been recommended to be between 32 and 36 °C. However optimal temperature remains unestablished. This study aimed to assess the relationship between target temperature and neurological outcome by using the Japanese nationwide registry. Methods: This retrospective observational cohort study was based on the Japanese association for acute medicine - out-of-hospital cardiac arrest (JAAM-OHCA) registry during 2014 to 2017. Our study included all initial rhythms and any cause of OHCA patients and excluded age < 18 and Glasgow Coma Scale score > 8. The primary outcome was 30 day favorable neurological outcome, defined as cerebral performance category (CPC) scale 1 and 2. First, to clarify the efficacy of TTM, the neurological outcome was compared whether patients received TTM or not. Next, to evaluate the relationship between neurological outcome and target temperature on TTM, the neurological outcome was compared hypothermia (34 °C) group with normothermia (36 °C) group . Single and multivariable logistic regression analysis was performed. Results: The study included 9930 patients. Of these, 1184 (11.9%) patients received TTM. Favorable neurological outcome was more present in TTM group than in no TTM group (39.7% vs. 4.3%, odds ratio [OR] 14.6, 95% confidence interval [CI] 12.5-17.1, p<0.001). Multivariable analysis showed TTM was associated with favorable neurological outcome (OR 1.6, 95%CI 1.1-2.3, p<0.001). Of TTM group, 801 (68.5%) patients received hypothermia management and 242 (20.7%) patients received normothermia management. Favorable neurological outcome was more present in the hypothermia group than in the normothermia group (42.6% vs. 34.3%, OR 1.42, 95% CI 1.1-1.9, p=0.022). However, the neurological outcome did not differ between these two groups (OR 0.84, 95%CI 0.46-1.5, p<0.57). Conclusions: TTM was significantly associated with favorable neurological outcome. However, neurological outcome was not associated with target temperature on TTM.

Favorable Neurological Outcome

Introduction: Therapeutic hypothermia (TH) for post cardiac arrest syndrome (PCAS) patients is standard strategy to reduce brain damage. However, current randomized control study (TTM: Target temperature management study, N Engl J Med 2013) suggested that simple target temperature did not improve outcome. Furthermore, there is no evidence, whether target temperature would be changed for each status of PCAS patients. Hypothesis: Lower target temperature could improve neurological outcome in PCAS patients. Methods: Participants with J-PULSE-Hypo study database were divided into the L group (32.0-33.9°C) and the M group (34-35°C). The favorable neurological outcomes (%, CPC 1-2 on 30th day) were compared between L and M groups in all and each subgroups with propensity score analysis with IPTW (inverse probability of treatment weighting) method as multivariate analysis. The subgroups were ages and interval from collapse to ROSC (return of spontaneous circulation). Results: 477 participants were analyzed. The comparison of each groups for favorable neurological outcome were that all groups (L: 64%, n = 42, vs M: 55%, n= 424, P = 0.234, multivariate: P = 0.452), age (≤60 y.o.) (L: 70% vs M: 67%, P = 0.717, multivariate: P = 0.657), age (>60 y.o.) (L: 50% vs M: 44%, P = 0.665, multivariate: P = 0.061), interval from collapse to ROSC (≤30 min.) (L: 88% vs M: 64%, P = 0.022, multivariate: P = 0.007), and interval from collapse to ROSC (>30 min.) (L: 21% vs M: 29%, P = 0.567, multivariate: P = 0.449). Conclusions: The PCAS victims within 30 min. from collapse to ROSC, would be treated by TH with less than 34°C target temperature.

Aim: We aimed to investigate the prognostic performance between serum NSE and cerebrospinal fluid (CSF) NSE for 6-month neurologic outcome in OHCA survivors underwent target temperature management (TTM). Hypothesis: We hypothesized that the NSE levels measured in the CSF would affect the change, earlier and more sensitively than serum, according to severity of hypoxic brain damage. Methods: This single-centre prospective observational study included out-of-hospital cardiac arrest (OHCA) patients underwent TTM. NSE levels were assessed in blood and CSF samples obtained immediately (Day 0), and 24 h (Day 1), 48 h (Day 2), and 72 h (Day 3) after return of spontaneous circulation (ROSC). The primary outcome was the 6-month neurological outcome. Results: We enrolled 34 patients (males, 24; 70.6%), 16 (47.1%) had a poor neurologic outcome. CSF NSE and serum NSE values were significantly higher in the poor outcome group compared to the good outcome group at each time point, except for serum Day 0. CSF NSE and serum NSE had area under curve (AUC) of 0.819-0.972 and 0.648-0.920, respectively. CSF NSE prognostic performances were significant higher than serum NSE at Day 1 and showed excellent AUC values (0.969; 95% Confidential Interval [CI] 0.844-0.999) and high sensitivity (93.8%; 95% CI 69.8-99.8) at 100% specificity. Conclusion: We found CSF NSE values were highly predictive and sensitive markers of 6-month poor neurological outcome in OHCA survivors treated with TTM at Day 1 after ROSC. Thus, CSF NSE level at day 1 after ROSC can be a useful early prognosticator in OHCA survivors.

Abstract Background: This study aimed to compare the day-specific association of blood–brain barrier (BBB) disruption with neurological outcomes in out-of-hospital cardiac arrest (OHCA) survivors treated with target temperature management (TTM).Methods: This retrospective single-center study included 68 OHCA survivors, who underwent TTM between April 2018 and December 2019. The albumin quotient (QA) was calculated as [albuminCSF] / [albuminserum] immediately (day 1), and at 24 h (day 2), 48 h (day 3), and 72 h (day 4) after return of spontaneous circulation (ROSC). The degree of BBB disruption was weighted using the following scoring system: 0.07 ≥ QA (normal), 0.01 ≥ QA > 0.007 (mild), 0.02 ≥ QA > 0.01 (moderate), and QA > 0.02 (severe). This system gave it 0 (normal), 1 (mild), 4 (moderate), and 9 (severe) points. Poor neurological outcome was determined at six months after ROSC and was defined as cerebral performance categories 3–5.Results: We enrolled 68 patients (males, 48; 71%); 37 (54%) of them had a poor neurological outcome. The distributions of this outcome at six months in patients with moderate and severe BBB disruption versus the other groups were 19/22 (80%) vs. 18/46 (50%) on day 1, 31/37 (79%) vs. 6/31 (32%) on day 2, 32/37 (81%) vs. 5/31 (30%) on day 3, and 32/39 (85%) vs. 5/29 (30%) on day 4 (P < 0.001). Using ROC analyses, the optimal cutoff values of QA levels for prediction of neurological outcomes were determined as: day 1, > 0.009 (sensitivity 56.8%, specificity 87.1%); day 2, > 0.012 (sensitivity 81.1%, specificity 87.1%); day 3, > 0.013 (sensitivity 83.8%, specificity 87.1%); day 4, > 0.013 (sensitivity 86.5%, specificity 87.1%); sum of all time points, > 0.039 (sensitivity 89.5%, specificity 79.4%); and scoring system, > 9 (sensitivity 91.9%, specificity 87.1%). Conclusions: Our results suggested that QA is a useful tool for predicting neurological outcomes in OHCA survivors treated with TTM. However, the prediction of poor neurological outcome using QA showed low sensitivity at 100% specificity. Thus, it could be used as part of a multimodal approach than as a single prognostic prediction tool.
