Abstract Background: Patients experiencing cardiac arrest outside medical facilities are at greater risk of death and might have negative neurological outcomes. Cardiopulmonary resuscitation duration affects neurological outcomes of such patients, which suggests that duration of CPR may be vital to patient outcomes.Objectives: The study aims to evaluate the impact of cardiopulmonary resuscitation duration on neurological outcome of patients who have suffered out-of-hospital cardiac arrest.Methods: Data were collected from emergency cases handled by a secondary hospital in industrial Jubail, Saudi Arabia, between 2015 and 2020. There were 257 out-of-hospital cardiac arrest cases, 236 of which resulted in death.Results: Bivariate analysis showed no significant association between cerebral performance category (CPC) outcomes and duration of CPR, gender and cause of death whereas there is statistically significant between CPC and age. (p = 0.001). However, a good CPC outcome was reported with a (mean) limited duration of 8.1 min of CPR; whereas, poor CPC outcomes were associated with prolonged periods of CPR, 13.2 min (mean). Similarly, youthfulness was associated with good CPC outcomes as revealed by the mean age of 5.8 years, whereas a mean rank of 14.9 years was aligned with a poor CPC outcome.Conclusion: Cardiopulmonary Resuscitation Duration out-of-hospital cardiac arrest does not significantly influence the patient neurological outcome in the current study hospital. Other variables may have a more significant effect.

Hence, the results revealed that death was more likely in elderly patients. The mean and standard deviation for the duration of emergency CPR procedures specifically in surviving patients were 26.5 ± 7.20 min, whereas in patients who died after the procedure, the mean and standard deviation for the duration of CPR were 29.6 ± 9.15 min. The mean age and standard deviation in surviving patients were found to be 38 ± 18.59 years, and 49.4 ± 23.39 years for those who died.Conclusion: Cardiopulmonary Resuscitation Duration out-of-hospital cardiac arrest does not significantly influence the patient survival in the current study hospital. Other variables may have a more significant effect.

Introduction: We have reported previously a favorable neurological outcome by extracorporeal cardiopulmonary resuscitation (ECPR) for out of hospital cardiac arrest. However, effects of ECPR on patients with prolonged pulseless electrical activity (PEA) are unclear. We analyzed etiology of patients with favorable neurological outcomes after ECPR for PEA with witness. Methods: In this single center retrospective study, from January 2007 to May 2018, we identified 68 patients who underwent ECPR for PEA with witness. Of these, 13 patients (19%) had good neurological outcome at 1 month (Glasgow-Pittsburgh Cerebral Performance Category (CPC):1-2, Group G), and 55 patients (81%) had unfavorable neurological outcome (CPC:3-5, Group B). We compared courses of treatment and causes/places of arrests between two groups. Results are expressed as mean ± SD. Results: Patient characteristics were not different between the two groups. Time intervals from collapse to induction of V-A ECMO were also not significantly different (Group G; 46.1 ± 20.2 min vs Group B; 46.8 ± 21.7 min, p=0.92). Ten patients achieved favorable neurological outcome among 39 (26%) with non-cardiac etiology. In cardiac etiology, only 3 of 29 patients (9%) had a good outcome at 1 month (p=0.08). In particular, 5 patients of 10 pulmonary embolism, and 4 of 4 accidental hypothermia responded well to ECPR with a favorable neurological outcome. Additionally, 6 of 13 (46%), who had in hospital cardiac arrest, had good outcome, whereas 7 of 55 (15%) who had out of hospital cardiac arrest, had good outcome (p=0.02). Conclusions: In our small cohort of cardiac arrest patients with pulmonary embolism or accidental hypothermia and PEA with witness, EPCR contributed to favorable neurological outcomes at 1 month.

Background: Studies have suggested that taurine may have neuro- and cardio-protective functions, but there is little research looking at taurine levels in patients after out-of-hospital cardiac arrest (OHCA). Our aim was to evaluate the association of taurine with mortality and neurological deficits in a well-defined cohort of OHCA patients. Methods: We prospectively measured serum taurine concentration in OHCA patients upon admission to the intensive care unit (ICU) of the University Hospital Basel (Switzerland). We analyzed the association of taurine levels and in-hospital mortality (primary endpoint). We further evaluated neurological outcomes assessed by the cerebral performance category scale. We calculated logistic regression analyses and report odds ratios (OR) and 95% confidence intervals (CI). We calculated different predefined multivariable regression models including demographic variables, comorbidities, initial vital signs, initial blood markers and resuscitation measures. We assessed discrimination by means of area under the receiver operating curve (ROC). Results: Of 240 included patients, 130 (54.2%) survived until hospital discharge and 110 (45.8%) had a favorable neurological outcome. Taurine levels were significantly associated with higher in-hospital mortality (adjusted OR 4.12 (95%CI 1.22 to 13.91), p = 0.02). In addition, a significant association between taurine concentration and a poor neurological outcome was observed (adjusted OR of 3.71 (95%CI 1.13 to 12.25), p = 0.03). Area under the curve (AUC) suggested only low discrimination for both endpoints (0.57 and 0.57, respectively). Conclusion: Admission taurine levels are associated with mortality and neurological outcomes in OHCA patients and may help in the risk assessment of this vulnerable population. Further studies are needed to assess whether therapeutic modulation of taurine may improve clinical outcomes after cardiac arrest.

AbstractObjective:This systemic review and meta-analysis was conducted to explore the impact of dispatcher-assisted bystander cardiopulmonary resuscitation (DA-BCPR) on bystander cardiopulmonary resuscitation (BCPR) probability, survival, and neurological outcomes with out-of-hospital cardiac arrest (OHCA).Methods:Electronically searching of PubMed, Embase, and Cochrane Library, along with manual retrieval, were done for clinical trials about the impact of DA-BCPR which were published from the date of inception to December 2018. The literature was screened according to inclusion and exclusion criteria, the baseline information, and interested outcomes were extracted. Two reviewers assessed the methodological quality of the included studies. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated by STATA version 13.1.Results:In 13 studies, 235,550 patients were enrolled. Compared with no dispatcher instruction, DA-BCPR tended to be effective in improving BCPR rate (I2 = 98.2%; OR = 5.84; 95% CI, 4.58-7.46; P <.01), return of spontaneous circulation (ROSC) before admission (I2 = 36.0%; OR = 1.17; 95% CI, 1.06-1.29; P <.01), discharge or 30-day survival rate (I2 = 47.7%; OR = 1.25; 95% CI, 1.06-1.46; P <.01), and good neurological outcome (I2 = 30.9%; OR = 1.24; 95% CI, 1.04-1.48; P = .01). However, no significant difference in hospital admission was found (I2 = 29.0%; OR = 1.09; 95% CI, 0.91-1.30; P = .36).Conclusion:This review shows DA-BPCR plays a positive role for OHCA as a critical section in the life chain. It is effective in improving the probability of BCPR, survival, ROSC before admission, and neurological outcome.

Background Little is known about the association between prehospital cardiopulmonary resuscitation duration for adults with out-of-hospital cardiac arrest and outcome by the location of arrests. This study aimed to investigate the association between prehospital cardiopulmonary resuscitation duration and one-month survival with favourable neurological outcome. Methods We analysed 276,391 adults aged 18 years and older with out-of-hospital cardiac arrest of medical origin before emergency medical service arrival. Prehospital cardiopulmonary resuscitation duration was defined as the time from emergency medical service-initiated cardiopulmonary resuscitation to prehospital return of spontaneous circulation or to hospital arrival. The primary outcome was one-month survival with favourable neurological outcome (cerebral performance category 1 or 2). The association between prehospital cardiopulmonary resuscitation duration and favourable neurological outcome was assessed using univariable and multivariable logistic regression analyses. Results The proportion of favourable neurological outcomes was 2.3% in total, 7.6% in public locations, 1.5% in residential locations and 0.7% in nursing homes ( P < 0.001). In univariable and multivariable logistic regression analyses, longer prehospital cardiopulmonary resuscitation duration was associated with poor neurological outcome, regardless of arrest location ( P for trend < 0.001). Patients with shockable rhythm in both public and residential locations had better neurological outcome than those in nursing homes at any time point, and residential and public locations had a similar neurological outcome tendency among patients with shockable rhythm. Conclusions Longer prehospital cardiopulmonary resuscitation duration was independently associated with a lower proportion of patients with favourable neurological outcomes. Moreover, the association between prehospital cardiopulmonary resuscitation duration and neurological outcome differed according to the location of arrest and the first documented rhythm.

Abstract Background A favorable neurological outcome is closely related to patient characteristics and total cardiopulmonary resuscitation (CPR) duration. The total CPR duration consists of pre-hospital and in-hospital durations. To date, consensus is lacking on the optimal total CPR duration. Therefore, this study aimed to determine the upper limit of total CPR duration, the optimal cut-off time at the pre-hospital level, and the time to switch from conventional CPR to alternative CPR such as extracorporeal CPR. Methods We conducted a retrospective observational study using prospective, multi-center registry of out-of-hospital cardiac arrest (OHCA) patients between October 2015 and June 2019. Emergency medical service–assessed adult patients (aged ≥ 18 years) with non-traumatic OHCA were included. The primary endpoint was a favorable neurological outcome at hospital discharge. Results Among 7914 patients with OHCA, 577 had favorable neurological outcomes. The optimal cut-off for pre-hospital CPR duration in patients with OHCA was 12 min regardless of the initial rhythm. The optimal cut-offs for total CPR duration that transitioned from conventional CPR to an alternative CPR method were 25 and 21 min in patients with initial shockable and non-shockable rhythms, respectively. In the two groups, the upper limits of total CPR duration for achieving a probability of favorable neurological outcomes < 1% were 55–62 and 24–34 min, respectively, while those for a cumulative proportion of favorable neurological outcome > 99% were 43–53 and 45–71 min, respectively. Conclusions Herein, we identified the optimal cut-off time for transitioning from pre-hospital to in-hospital settings and from conventional CPR to alternative resuscitation. Although there is an upper limit of CPR duration, favorable neurological outcomes can be expected according to each patient’s resuscitation-related factors, despite prolonged CPR duration.

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: To investigate the impact of hyperoxia that developed immediately after extracorporeal membrane oxygenation (ECMO)-assisted cardiopulmonary resuscitation (ECPR) on patients’ 30-day neurological outcomes after out-of-hospital cardiac arrest (OHCA). Methods: This study retrospectively analyzed data from the Japanese OHCA registry from June 2014 to December 2017. We analyzed adult patients (18 years or older) who had undergone ECPR. Eligible patients were divided into the following three groups based on their initial partial pressure of oxygen in arterial blood (PaO2) levels after ECMO pump-on: normoxia group, PaO2 ≤ 200 mm Hg; moderate hyperoxia group, 200 mm Hg < PaO2 ≤ 400 mm Hg; and extreme hyperoxia group, PaO2 > 400 mm Hg. The primary and secondary outcomes were 30-day favorable neurological outcomes. Logistic regression statistical analysis model of 30-day favorable neurological outcomes was performed after adjusting for multiple propensity scores calculated using pre-ECPR covariates and for confounding factors post-ECPR.Results: Of the 34 754 patients with OHCA enrolled in the registry, 847 were included. The median PaO2 level was 300 mm Hg (interquartile range: 148–427 mm Hg). Among the eligible patients, 277, 313, and 257 were categorized as normoxic, moderately hyperoxic, and extremely hyperoxic, respectively. Moderate hyperoxia was not significantly associated with neurologically favorable outcomes compared with normoxia as a reference (adjusted odds ratio, 0.86; 95% confidence interval: 0.55–1.35; p = 0.51). However, extreme hyperoxia was associated with less neurologically favorable outcomes when compared with normoxia (adjusted odds ratio, 0.48; 95% confidence interval: 0.29–0.82; p = 0.007).Conclusions: For patients with OHCA who received ECPR, extreme hyperoxia (PaO2 > 400 mm Hg) was associated with poor neurological outcomes. Avoidance of extreme hyperoxia may improve neurological outcomes in patients with OHCA treated with ECPR.

Background and Aim: The benefit of early coronary angiography (CAG) and revascularization in resuscitated out-of-hospital cardiac arrest (OHCA) is unclear. We evaluated the association between early CAG and clinical outcomes in these patients. Methods: Data on all resuscitated adult OHCA cases of cardiac etiology between 2011-2015 were extracted from the prospective Singapore Pan-Asian Resuscitation Outcomes Study and linked with data from the national database of cardiac procedures. The 30-day survival and neurological outcomes (good outcome defined as Cerebral Performance Category [CPC] 1 or 2) were compared between patients undergoing early CAG (within 1-calender day) and patients not undergoing early CAG. Inverse probability weighted estimator was used to adjust for propensity to perform early CAG and PCI. Results: Of 976 consecutive patients who survived to admission (mean age 64±13, 73.7% males), 401 (41.1%) patients underwent CAG and obstructive coronary artery disease (CAD) was present in 352 (87.8%), of whom 284 (70.8%) underwent revascularization. Patients who underwent early CAG (n=337[34.5%]) were significantly different compared to those who underwent delayed or no CAG (n=639[65.5%]) (Table 1). Early CAG and PCI patients had improved survival and better neurological outcomes (adjusted odds ratio [AOR] 3.806 [95% CI 1.675 - 8.648] and AOR 3.075 [95% CI 1.119 - 8.451]), compared to those without. The odds of survival decreased with epinephrine administration (AOR 0.357 [95% CI 0.199 - 0.640]), but increased with an initial shockable rhythm (AOR 6.587 [95% CI 3.659 - 11.861]). The rates of bleeding (2% vs 0%, p=0.300) and stroke (1.6% vs 1.9%, p=0.880) were not increased with early intervention. Conclusion: Early CAG and PCI after OHCA were associated with improved clinical outcomes after OHCA without increasing complications. Further studies are required to identify the characteristics of patients who would benefit most from this invasive strategy.

Abstract Background Refractory cardiac arrest (CA), as defined by the absence of a return of spontaneous circulation (ROSC) is associated with poor prognosis. Current guidelines advocate the use of extracorporeal cardiopulmonary resuscitation (ECPR) for selected patients with CA. Although previous studies have reported the association of survival with some prognostic factors such as age, bystander CPR attempt, low-flow duration or lactate serum level, the impact of the evaluation of coronary artery by coronary angiography (CAG) and the revascularization of coronary artery stenosis have not been sufficiently elucidated. Purpose We sought to investigate impact of the CAG and the revascularization of coronary artery stenosis to predict mortality and neurological outcome at 30 days in out-of-hospital CA (OHCA) patients resuscitated by ECPR. Methods 1382 out-of-hospital cardiac arrest patients were transferred to our critical care center, of which 899 patients with refractory CA at the emergency department were extracted from the institutional consecutive database between January 2015 and December 2018. Among those patients, we performed ECPR for 85 patients, who were successfully resuscitated. To predict mortality in hospital and neurological outcome at 30 days, we investigated basic patients' characteristics, pre-hospital information, and post-hospital care including CAG and coronary revascularization. Results Among those who had first resuscitated by ECPR, 20 patients (23.5%) survived and 10 patients (11.8%) achieved good neurological outcome (cerebral-performance-category (CPC) =1 or 2) at 30 days. We performed CAG for 40 patients (47.1%) and revascularization by percutaneous coronary intervention for 25 patients (29.4%). Younger age (P=0.037), CAG (P=0.001), PCI (P=0.001), and hypothermia therapy (P<0.001) were associated with low mortality. In the multivariate analysis, age (Odds ratio (OR) 0.95; 95% confidence interval (CI) 0.91–0.99; P=0.0025), PCI (OR 4.5; 95% CI 1.15–17.6; P=0.031), and hypothermia therapy (OR 13.7; 95% CI 1.52–124; P=0.020) were independent predictors of 30-days survival. Without diabetes mellitus (P=0.024), CAG (P<0.001), PCI (P=0.006), and hypothermia therapy (P=0.038) were associated with good neurological outcome. PCI (OR 7.39; 95% CI 1.73–31.6; P<0.001) was independently predictive for good neurological outcome. Conclusions Successful PCI was an independent predictor of 30-days survival and good neurological outcome in OHCA patients who were resuscitated by ECPR.
