Background
The neurological prognosis is poor for patients suffering from out-of-hospital cardiac arrest (OHCA), in the absence of bystander cardio pulmonary resuscitation (CPR), and showing asystole as the initial waveform. However, such patients have the potential of resuming social activity if cerebral tissue oxygen saturation can be preserved.Case presentation
We recently encountered a 60-year-old man who had suffered an OHCA in the absence of bystander CPR, and who successfully resumed complete social activity despite initial asystole and requiring at least 75 min of chest compressions before return of spontaneous circulation (ROSC). In this case, chest compression was appropriately performed concurrently with real-time evaluation of cerebral tissue oxygenation using near-infrared spectroscopy (NIRS). As a result, the cerebral tissue oxygenation was well maintained, leading to resumption of social activity.Conclusions
Improved neurological prognoses can be expected if OHCA patients with the potential for social activity resumption are identified, using NIRS, and effective cardiopulmonary and cerebral resuscitation is performed while visually checking CPR quality. 相似文献3.

Objectives
To assess the difference in survival and neurological outcomes between endotracheal tube (ETT) intubation and supraglottic airway (SGA) devices used during out-of-hospital cardiac arrest (OHCA).Methods
A systematic search of five databases was performed by two independent reviewers until September 2018. Included studies reported on (1) OHCA or cardiopulmonary resuscitation, and (2) endotracheal intubation versus supraglottic airway device intubation. Exclusion criteria (1) stimulation studies, (2) selectively included/excluded patients, (3) in-hospital cardiac arrest. Odds Ratios (OR) with random effect modelling was used. Primary outcomes: (1) return of spontaneous circulation (ROSC), (2) survival to hospital admission, (3) survival to hospital discharge, (4) discharge with a neurologically intact state.Results
Twenty-nine studies (n?=?539,146) showed that overall, ETT use resulted in a heterogeneous, but significant increase in ROSC (OR?=?1.44; 95%CI?=?1.27 to 1.63; I2?=?91%; p?<?0.00001) and survival to admission (OR?=?1.36; 95%CI?=?1.12 to 1.66; I2?=?91%; p?=?0.002). There was no significant difference in survival to discharge or neurological outcome (p?>?0.0125). On sensitivity analysis of RCTs, there was no significant difference in ROSC, survival to admission, survival to discharge or neurological outcome (p?>?0.0125). On analysis of automated chest compression, without heterogeneity, ETT provided a significant increase in ROSC (OR?=?1.55; 95%CI?=?1.20 to 2.00; I2?=?0%; p?=?0.0009) and survival to admission (OR?=?2.16; 95%CI?=?1.54 to 3.02; I2?=?0%; p?<?0.00001).Conclusions
The overall heterogeneous benefit in survival with ETT was not replicated in the low risk RCTs, with no significant difference in survival or neurological outcome. In the presence of automated chest compressions, ETT intubation may result in survival benefits. 相似文献4.

Purpose
We aimed to examine the serial changes in coagulofibrinolytic markers that occurred after the restoration of spontaneous circulation (ROSC) in cardiac arrest patients, who were treated with targeted temperature management (TTM). We also evaluated the association between the disseminated intravascular coagulation (DIC) score and clinical outcomes.Methods
This was a single-centre, retrospective observational study that included cardiac arrest patients who were treated with TTM from May 2012 to December 2015. The prothrombin time (PT) and partial thromboplastin time (PTT), along with the levels of fibrinogen, fibrin degradation products (FDP), and D-dimer were obtained after ROSC and on day 1, 2, and 3. The DIC score was calculated after ROSC. The primary outcome was the neurologic outcome at discharge and the secondary outcome was the 6-month mortality.Results
This study included 317 patients. Of these, 222 (70.0%) and 194 (61.2%) patients had a poor neurologic outcome at discharge and 6-month mortality, respectively. The PT, PTT, and fibrinogen level significantly increased over time, while the FDP and D-dimer levels decreased during first three days after ROSC. Multivariate logistic analyses revealed that the DIC score remained a significant predictor for poor neurologic outcome (odds ratio [OR], 1.800; 95% confidence interval [CI], 1.323–2.451) and 6-month mortality (OR, 1.773; 95% CI, 1.307–2.405).Conclusion
The activity of coagulation and fibrinolysis decreased over time. An increased DIC score was an independent prognostic factor for poor neurologic outcome and 6-month mortality. 相似文献5.

Background
Sodium bicarbonate administration is mostly restricted to in-hospital use in Taiwan. This study was conducted to investigate the effect of sodium bicarbonate on outcomes among patients with out-of-hospital cardiac arrest (OHCA).Methods
This population-based study used a 16-year database to analyze the association between sodium bicarbonate administration for resuscitation in the emergency department (ED) and outcomes. All adult patients with OHCA were identified through diagnostic and procedure codes. The primary outcome was survival to hospital admission and secondary outcome was the rate of death within the first 30 days of incidence of cardiac arrest. Cox proportional-hazards regression, logistic regression, and propensity analyses were conducted.Results
Among 5589 total OHCA patients, 15.1% (844) had survival to hospital admission. For all patients, a positive association was noted between sodium bicarbonate administration during resuscitation in the ED and survival to hospital admission (adjusted odds ratio [OR]: 4.47; 95% confidence interval [CI]: 3.82–5.22, p < 0.001). In propensity-matched patients, a positive association was also noted (adjusted OR, 4.61; 95% CI: 3.90–5.46, p < 0.001).Conclusions
Among patients with OHCA in Taiwan, administration of sodium bicarbonate during ED resuscitation was significantly associated with an increased rate of survival to hospital admission. 相似文献6.

Objective
This study assessed the association between the timing of first epinephrine administration (EA) and the neurological outcomes following out-of-hospital cardiac arrests (OHCAs) with both initial shockable and non-shockable rhythms.Methods
This was a post-hoc analysis of a multicenter prospective cohort study (SOS-KANTO 2012), which registered OHCA patients in the Kanto region of Japan from January 2012 to March 2013. We included consecutive adult OHCA patients who received epinephrine. The primary result included 1-month favorable neurological outcomes defined as cerebral performance category (CPC) 1 or 2. Secondary results included 1-month survival and return of spontaneous circulation (ROSC) after arrival at the hospital. Multivariable logistic regression analysis determined the association between delay per minute of the time from call to first EA in both pre- or in-hospital settings and outcomes.Results
Of the 16,452 patients, 9344 were eligible for our analyses. In univariable analysis, the delay in EA was associated with decreased favorable neurological outcomes only when the initial rhythm was a non-shockable rhythm. In multivariable analyses, delay in EA was associated with decreased ROSC (adjusted odds ratio [OR] for one minute delay, 0.97; 95% confidence interval [CI], 0.96–0.98) and 1-month survival (adjusted OR, 0.95; 95% CI, 0.92–0.97) when the initial rhythm was a non-shockable rhythm, whereas during a shockable rhythm, delay in EA was not associated with decreased ROSC and 1-month survival.Conclusions
While assessing the effectiveness of epinephrine for OHCA, we should consider the time-limited effects of epinephrine. Additionally, consideration of early EA based on the pathophysiology is needed. 相似文献7.

Background
Mild induced hypothermia (MIH) was introduced for post cardiac arrest care in Sweden in 2003, based on two clinical trials. This retrospective study evaluated its association with 30-day survival after out-of-hospital cardiac arrest (OHCA) in a Swedish community from 2003 to 2015.Methods
Out of 3680 patients with OHCA, 1100 were hospitalized after return of spontaneous circulation and 871 patients who remained unconscious were included in the analysis. Prehospital data were extracted from the Swedish Registry of Cardiopulmonary Resuscitation and in-hospital data were extracted from clinical records. Propensity score analysis on complete data sets and multivariable logistic regression with multiple imputations to compensate for missing data were performed.Results
Unadjusted 30-day survival was 23.5%; 37% in 386/871 (44%) MIH treated and 13% in 485/871 (56%) non-MIH treated patients. Unadjusted odds ratio (OR) for 30-day survival in patients treated with MIH compared to non-MIH treated patients was 3.79 (95% CI 2.71–5.29; p < 0.0001). Using stratified propensity score analysis and in addition adjusting for in-hospital factors, 30-day survival was not significantly different in patients treated with MIH compared to non-MIH treated patients; OR 1.33 (95% CI 0.83–2.15; p = 0.24). Using multiple imputations to handle missing data yielded a similar adjusted OR of 1.40 (95% CI 0.88–2.22; p = 0.15). Good neurologic outcome at hospital discharge was seen in 82% of patients discharged alive.Conclusion
Treatment with MIH was not significantly associated with increased 30-day survival in patients remaining unconscious after OHCA when adjusting for potential confounders. 相似文献8.

Purpose
To investigate differences in chronological variations in characteristics and outcomes of out-of-hospital cardiac arrests (OHCAs) between elderly and non-elderly patients.Methods
We retrospectively analyzed bystander-witnessed OHCAs without prehospital involvement of physicians between January 2007 and December 2014 in Japan. We considered the following time periods: night-time (23:00–5:59) and non-night-time; we further divided non-night-time into dinnertime (18:00–20:29) and other non-night-time. Subsequently, we analyzed chronological variations in factors associated with OHCA survival using univariate and multivariable logistic regression analyses for unmatched and propensity-matched pairs, respectively.Results
For elderly (≥65?years old, N?=?201,073) and non-elderly (≥10, <65?years old, N?=?57,124) OHCA patients, survival rates were lower during night-time than during non-night-time (elderly, 2.8% vs 1.6%; non-elderly, 9.8% vs 7.7%). The trend for incidences of bystander-witnessed OHCA in the elderly showed three peaks associated with breakfast-time, lunchtime, and dinnertime. However, a transient but considerable decrease in survival rates was observed at dinnertime (1.9% at dinnertime and 3.0% during other non-night-time). OHCAs in the elderly at dinnertime were characterized by low proportions of presumed cardiac etiologies and shockable initial rhythm. However,even after adjusting for these and other factors associated with survival,survival rates were significantly lower at dinnertime than during other non-night-time for elderly OHCA patients (adjusted odds ratio, 1.29; 95% confidence interval, 1.18–1.41, with dinnertime as reference). This difference was significant even after propensity matching with significant augmentation in winter.Conclusions
Dinnertime, particularly in winter, is associated with lower survival in elderly OHCA patients. 相似文献9.

Introduction
Out of hospital cardiac arrest (OHCA) is a time critical and heterogeneous presentation. The most appropriate management strategies remain an issue for debate. The aim of this systematic review and meta-analysis was to determine the association of epinephrine versus placebo with return of spontaneous circulation, survival to hospital admission, survival to hospital discharge and neurological outcomes in out of hospital cardiac arrest.Methods
A systematic review of five databases was performed from inception to August 2018. Only randomised controlled trials were considered eligible for inclusion. The primary outcome was survival to hospital discharge. Secondary outcomes were ROSC, survival to hospital admission, neurological function on discharge and three-month survival. All studies were assessed for level of evidence and risk of bias.Results
Five randomised controlled trials with 17,635 patients were identified for inclusion. Use of epinephrine was associated with increased ROSC (OR?=?3.10; 95% CI?=?2.16 to 4.45; I2?=?74%; p?<?0.0001) and increased survival to hospital admission OR?=?2.52; 95% CI?=?1.63 to 3.88; I2?=?94%; p?<?0.0001). However, epinephrine was not associated with increased survival to discharge (OR?=?1.09; 95% CI?=?0.48 to 2.47; I2?=?77%; p?=?0.84) or differences in neurological outcomes (OR?=?0.81; 95% CI?=?0.34 to 1.96).Discussion
This study was a systematic review and meta-analysis of epinephrine versus placebo in OHCA. The use of epinephrine was associated with improved ROSC and survival to hospital admission. However, use of epinephrine was not associated with a significant difference in survival to hospital discharge, neurological outcomes or survival to 3?months. Further research is required to control for the confounders during inpatient management. 相似文献10.

Purpose
To investigate temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts and their association with survival after bystander-witnessed out-of-hospital cardiac arrests (OHCAs).Methods
We retrospectively analyzed the neurologically favorable 1-month survival and the parameters related to dispatcher assisted cardiopulmonary resuscitation (DA-CPR) and bystander CPR (BCPR) for 227,524 OHCA patients between 2007 and 2013 in Japan. DA-CPR sensitivity for OHCAs, bystander's compliance to DA-CPR assessed by the proportion of bystanders who follow DA-CPR, and performance of BCPR measured by the rate of bystander-initiated CPR in patients without DA-CPR were calculated as indices of resuscitation efforts.Results
Performance of BCPR was only similar to temporal variations in the survival (correlation between hourly paired values, R2 = 0.263, P = 0.01): a lower survival rate (3.4% vs 4.2%) and performance of BCPR (23.1% vs 30.8%) during night-time (22:00–5:59) than during non-night-time. In subgroup analyses based on interaction tests, all three indices deteriorated during night-time when OHCAs were witnessed by non-family (adjusted odds ratio, 0.73–0.82), particularly in non-elderly patients. The rate of public access defibrillation for these OHCAs markedly decreased during night-time (adjusted odds ratio, 0.49) with delayed emergency calls and BCPR initiation. Multivariable logistic regression analyses revealed that the survival rate of non-family-witnessed OHCAs was 1.83-fold lower during night-time than during non-night-time.Conclusions
Dispatcher-assisted and bystander-initiated resuscitation efforts are low during night-time in OHCAs witnessed by non-family. A divisional alert system to recruit well-trained individuals is needed in order to improve the outcomes of night-time OHCAs witnessed by non-family bystanders. 相似文献11.

Aim
We investigated whether DA-CPR would have the same effect as spontaneously-delivered bystander CPR.Methods
A total of 37,899 witnessed cardiogenic out of hospital cardiac arrest (OHCA) selected from a nationwide Utstein-Japanese database between 2008 and 2012. Patients were divided into four groups as follows: CPR initiated with dispatcher assistance (DA-CPR; n = 10,424), no CPR provided with dispatcher assistance (DA-No CPR; n = 4658), spontaneously-delivered bystander CPR provided without DA (BCPR; n = 6630), and both BCPR and dispatcher assistance was not provided (No BCPR-No DA; n = 16,187). The primary endpoint was rate of shockable rhythm on the initial ECG, return of spontaneous circulation (ROSC) on the field. A multivariable logistic regression analysis was used. Adjusted odds ratios (AOR) are presented as 95% confidence intervals (95% CIs) among the groups.Results
The rate of DA-CPR implementation has gradually increased since 2005. In comparison with DA-No CPR, both spontaneously-delivered BCPR and DA-CPR were significantly associated with the following factors: increased rate of shockable rhythm on the initial ECG (AOR, 1.75 and 1.72; 95% CI, 1.67 to 1.85 and 1.63 to 1.83),improved field ROSC (AOR, 1.42 and 1.40; 95% CI, 1.33 to 1.52 and 1.30 to 1.51) and 1-month favorable neurological outcomes (AOR, 1.72 and 1.80; 95% CI, 1.59 to 1.88 and 1.64 to 1.97), respectively.Conclusions
We found that the spontaneously delivered BCPR group showed favorable results. In comparison to the DA-No BCPR group, DA-CPR group resulted in the nearly equivalent effect as spontaneously-delivered BCPR group. Further standard dispatcher education is indicated. 相似文献12.

Background
It is unclear whether the number of paramedics in an ambulance improves the outcome of patients with out-of-hospital cardiac arrest (OHCA) or not.Methods and Results
This study was a prospective, observational study conducted on patients with OHCA. Patients were divided into the One-paramedic group (Group O) and the Two-or-more-paramedic group (Group T) and we analyzed the differences. Patients who were treated with only basic life support during transportation, and whose cause of cardiac arrest were extrinsic cause such as trauma and poisoning were excluded. Good neurological outcome was defined as cerebral performance category (CPC) 1 or 2.In Group O, there were 1516 patients (male/female, 922/594). In Group T, there were 2932 patients (male/female, 1798/1134). Return of spontaneous circulation (ROSC) was obtained in 528 patients (34.8%) in Group O and 1058 patients (36.1%) in Group T (p = 0.589). 320 patients (21.1%) in Group O and 656 patients (22.4%) in Group T were admitted to hospital after ROSC (p = 0.461). At 90 days, there were 57 survivors (3.8%) in Group O and 114 survivors (3.9%) in Group T (p = 0.873). At 90 days, 14 patients (0.9%) in Group T had a CPC of 1 or 2, while 30 patients (1.0%) in Group T did so (p = 0.87). From the results of logistic regression analysis, age [odds ratio (OR): 0.983, 95% confidence interval (CI): 0.952–0.993], witnessed OHCA (OR: 4.583, 95% CI: 1.587–13.234), and shockable rhythm as first documented (OR: 19.67, 95% CI: 9.181–42.13) were associated with good outcome.Conclusion
The number of paramedics in an ambulance did not affect the outcome in OHCA patients. 相似文献13.

Background
The effects and relative benefits of advanced airway management and epinephrine on patients with out-of-hospital cardiac arrest (OHCA) who were defibrillated are not well understood.Methods
This was a prospective observational study. Using data of all out-of-hospital cardiac arrest cases occurring between 2005 and 2013 in Japan, hierarchical logistic regression and conditional logistic regression along with time-dependent propensity matching were performed. Outcome measures were survival and minimal neurological impairment [cerebral performance category (CPC) 1 or 2] at 1 month after the event.Results
We analyzed 37,873 cases that met the inclusion criteria. Among propensity-matched patients, advanced airway management and/or prehospital epinephrine use was related to decreased rates of 1-month survival (adjusted odds ratio 0.88, 95% confidence interval 0.80 to 0.97) and CPC (1, 2) (adjusted odds ratio 0.56, 95% confidence interval 0.48 to 0.66). Advanced airway management was related to decreased rates of 1-month survival (adjusted odds ratio 0.89, 95% confidence interval 0.81to 0.98) and CPC (1, 2) (adjusted odds ratio 0.54, 95% confidence interval 0.46 to 0.64) in patients who did not receive epinephrine, whereas epinephrine use was not related to the outcome measures.Conclusions
In defibrillated patients with OHCA, advanced airway management and/or epinephrine are related to reduced long-term survival, and advanced airway management is less beneficial than epinephrine. However, the proportion of patients with OHCA who responded to an initial shock was very low in the study subjects, and the external validity of our findings might be limited. 相似文献14.

Objective
The aim of this study was to conduct a meta-analysis to evaluate the efficacy of vasopressin-epinephrine compared to epinephrine alone in patients who suffered out-of-hospital cardiac arrest (OHCA).Methods
Relevant studies up to February 2017 were identified by searching in PubMed, EMBASE, the Cochrane Library, Wanfang for randomized controlled trials(RCTs) assigning adults with cardiac arrest to treatment with vasopressin-epinephrine (VEgroup) vs adrenaline (epinephrine) alone (E group). The outcome point was return of spontaneous circulation (ROSC) for patients suffering from OHCA. Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were explored.Results
Individual patient data were obtained from 5047 participants who experienced OHCA in nine studies. Odds ratios (ORs) were calculated using a random-effects model and results suggested that vasopressin-epinephrine was associated with higher rate of ROSC (OR = 1.67, 95% CI = 1.13–2.49, P < 0.00001, and total I2 = 83%). Subgroup showed that vasopressin-epinephrine has a significant association with improvements in ROSC for patients from Asia (OR = 3.30, 95% CI = 1.30–7.88); but for patients from other regions, there was no difference between vasopressin-epinephrine and epinephrine alone (OR = 1.07, 95% CI = 0.72–1.61).Conclusion
According to the pooled results of the subgroup, combination of vasopressin and adrenaline can improve ROSC of OHCA from Asia, but patients from other regions who suffered from OHCA cannot benefit from combination of vasopressin and epinephrine. 相似文献15.

Introduction
The relationship between time of day and the clinical outcomes of patients with out-of-hospital cardiac arrest (OHCA) remains inconclusive. We undertook a meta-analysis to assess the available evidence on the relationship between nighttime and prognosis for patients with OHCA.Materials and methods
PubMed and EMBASE were searched through June 20, 2018, to identify all studies assessing the relationship between nighttime and prognosis for patients with OHCA. Random effects modes were used to estimate odds ratios (ORs) with 95% confidence intervals (CIs).Results
Eight observational studies met the inclusion criteria. Meta-analysis of 8 studies showed that compared with nighttime, the daytime OHCA patients had higher 1-month/in-hospital survival (OR, 1.25; 95% CI, 1.15–1.37; P?=?0.00), with high heterogeneity among the studies (I2?=?82.8%, P?=?0.00).Conclusions
Patients who experienced OHCA during the nighttime had lower 1-month/in-hospital survival than those with daytime OHCA. In addition to arrest event and pre-hospital care factors, patients' comorbidity and hospital-based care may also be responsible for lower survival at night. 相似文献16.

Background
Epinephrine is recommended for the treatment of non-shockable out of hospital cardiac arrest (OHCA) to obtain return of spontaneous circulation (ROSC). Epinephrine efficiency and safety remain under debate.Objective
We propose to describe the association between the cumulative dose of epinephrine and the failure of ROSC during the first 30?min of advanced life support (ALS).Methodology
A retrospective observational cohort study using the Paris SAMU 75 registry including all non-traumatic OHCA. All OHCA receiving epinephrine during the first 30?min of ALS were enrolled. Cumulative epinephrine dose given during ALS to ROSC was retrieved from medical reports.Results
Among 1532 patients with OHCA, 776 (51%) had initial non-shockable rhythm. Fifty-four patients were excluded for missing data.The mean value of cumulative dose of epinephrine was 10?±?4?mg in patients who failed to achieve ROSC (ROSC?) and 4?±?3?mg (p?=?0.04) for those who achieved ROSC.ROC curve analysis indicated a cut-off point of 7?mg total cumulative epinephrine associated with ROSC? (AUC?=?0.89 [0.86–0.92]).Using propensity score analysis including age, sex and no-flow duration, association with ROSC? only remained significant for epinephrine?>?7?mg (p?≤10–3, OR [CI95]?=?1.53 [1.42–1.65]).Conclusion
An association between total cumulative epinephrine dose administered during OHCA resuscitation and ROSC? was reported with a threshold of 7?mg, best identifying patients with refractory OHCA. We suggest using this threshold in this context to guide the termination of ALS and early decide on the implementation of extracorporeal life support or organ harvesting in the first 30?min of ALS. 相似文献17.
Background
Experimental and animal studies suggested that vasopressin may have a favorable survival profile during CPR. This meta-analysis aimed to determine the efficacy of vasopressin in adult cardiac patients.Methodology
Meta-analysis of randomized control trials (RCTs) comparing the efficacy of vasopressin containing regimen during CPR in adult cardiac arrest population with an epinephrine only regimen.Results
A total of 6120 patients from 10 RCTs were included in this meta-analysis. Vasopressin use during CPR has no beneficial impact in an unselected population in ROSC [OR 1.19, 95% CI 0.93, 1.52], survival to hospital discharge [OR 1.13, 95% CI 0.89, 1.43], survival to hospital admission [OR 1.12, 95% CI 0.99, 1.27] and favorable neurological outcome [OR 1.02, 95% CI 0.75, 1.38]. ROSC in “in-hospital” cardiac arrest setting [OR 2.20, 95% CI 1.08, 4.47] is higher patients receiving vasopressin. Subgroup analyses revealed equal or higher chance of ROSC [OR 2.15, 95% CI 1.00, 4.61], higher possibility of survival to hospital discharge [OR 2.39, 95% CI 1.34, 4.27] and favorable neurological outcome [OR 2.58, 95% CI 1.39, 4.79] when vasopressin was used as repeated boluses of 4–5 times titrating desired effects during CPR.Conclusion
ROSC in “in-hospital” cardiac arrest patients is significantly better when vasopressin was used. A subgroup analysis of this meta-analysis found that ROSC, survival to hospital admission and discharge and favorable neurological outcome may be better when vasopressin was used as repeated boluses of 4–5 times titrated to desired effects; however, overall no beneficial effect was noted in unselected cardiac arrest population. 相似文献18.
Objective
The objective of this study is to evaluate the efficacy of cardiocerebral resuscitation (CCR) vs cardiopulmonary resuscitation (CPR) for patients with out-of-hospital cardiac arrest (OHCA).Methods
We conducted a systematic review of controlled trials and observational studies. We searched Cochrane Central Register of Controlled Trials; MEDLINE; Embase; and Chinese databases such as VIP, CNKI, WANFANG, and CBM from their inception to September 2010. Data from original studies were extracted and assessed with predefined criteria.Results
Thirteen studies comprising 3 randomized controlled trials and 10 observational studies were included. Pooled analysis of 4 observational studies suggested that neurologically intact survival of patients with OHCA was improved in CCR group (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.07-1.97). Survival to hospital discharge in the CCR group was superior or at least equal to that in CPR group (randomized controlled trial OR, 1.25; 95% CI, 1.01-1.55; cohort studies OR, 1.15; 95% CI, 0.72-1.82; case-control studies OR 0.85; 95% CI, 0.65-1.12). In the subgroup analysis of patients with a shockable rhythm as an initial rhythm, survival to hospital discharge was significantly improved in the CCR group (cohort studies OR, 2.03; 95% CI, 1.44-2.86). However, when only noncardiac origin cardiac arrest was taken into consideration, survival rate was better in the CPR group (cohort studies OR, 0.87; 95% CI, 0.77-0.98).Conclusion
Cardiocerebral resuscitation might be equivalent or superior to CPR in patients with OHCA in both survival rate and neurologic benefits. Further work is needed to assess the efficacy of CCR for victims who had OHCA of noncardiac causes. 相似文献19.

Objective
To investigate the relationship between hypotension in the first 3 h after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest.Method
This retrospective cohort study occurred at two regional hospitals and included adult OHCA patients who experienced ROSC from July 1, 2014 to December 31, 2015. Hemodynamic and inotrope administration data were retrieved for 3 h after ROSC. We calculated the hypotensive exposure index (HEI) as the surrogate marker of the exposure of hypotension. The area under the ROC curve and multivariate logistic regression models were performed to analyze the effect of HEI on survival. Mean arterial pressure (MAP) was explored in the surviving and non-surviving patient groups using repeated measures MANCOVA, adjusted for the use of inotropes and down time.Results
A total of 289 patients were included in the study, and 29 survived. The median 1-hour HEI and 3-hour HEI were significantly lower in the survival group (p < 0.001). The area under the ROC curve for 3-hour HEI was 0.861. The repeated measures MANCOVA indicated that an interaction existed between post-ROSC time and downtime [F(5,197) = 2.31, p = 0.046]. No significant change in the MAP was observed in the 3 h after ROSC, except in the group with a prolonged down time. According to the tests examining the effects of the use of inotropes on the survival outcomes of the different subjects, the MAP was significantly higher in the surviving group [F(1,201) = 4.11; p = 0.044; ηp2 = 0.020].Conclusion
Among the patients who experienced ROSC after OHCA, post-ROSC hypotension was an independent predictor of survival. 相似文献20.
