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2.
The effect of team-based CPR on outcomes in out of hospital cardiac arrest patients: A meta-analysis
Objectives
The objective of this systematic review and meta-analysis was to determine the effects of team cardiopulmonary resuscitation (CPR) on outcomes of patients with out-of-hospital cardiac arrest (OHCA).Methods
A systematic literature review was performed using PubMed, EMBASE, and the Cochrane database to identify relevant articles for this meta-analysis. All studies that described the implementation of team CPR performed by emergency medical services for OHCA patients with presumed cardiac etiology were included in this study. Outcomes included return of spontaneous circulation (ROSC), survival to hospital discharge, and good neurological recovery.Results
A total of 2504 studies were reviewed. After excluding studies according to exclusion criteria, 4 studies with 15,455 OHCA patients were included in this study. The odds of survival and neurologic recovery for patients who received team CPR were higher than those for patients who did not (survival odds ratio [OR]: 1.68; 95% confidence interval [CI]: 1.48–1.91; neurologic recovery OR: 1.52; 95% CI: 1.31–1.77). There was no significant difference in the odds of ROSC between the two patient groups (OR: 1.59; 95% CI: 0.76–3.33).Conclusions
In this meta-analysis, team CPR improved the outcomes of OHCA patients, consistently increasing their odds of survival to discharge and neurologic recovery. 相似文献3.

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4.

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5.
Conversion to shockable rhythms during resuscitation and survival for out-of hospital cardiac arrest
Win Wah Khin Lay Wai Pin Pin Pek Andrew Fu Wah Ho Omer Alsakaf Michael Yih Chong Chia Julina Md Noor Kentaro Kajino Nurun Nisa Amatullah De Souza Marcus Eng Hock Ong 《The American journal of emergency medicine》2017,35(2):206-213
Background
In out of hospital cardiac arrest (OHCA), the prognostic influence of conversion to shockable rhythms during resuscitation for initially non-shockable rhythms remains unknown. This study aimed to assess the relationship between initial and subsequent shockable rhythm and post-arrest survival and neurological outcomes after OHCA.Methodology
This was a retrospective analysis of all OHCA cases collected from the Pan-Asian Resuscitation Outcomes Study (PAROS) registry in 7 countries in Asia between 2009 and 2012. We included OHCA cases of presumed cardiac etiology, aged 18-years and above and resuscitation attempted by EMS. We performed multivariate logistic regression analyses to assess the relationship between initial and subsequent shockable rhythm and survival and neurological outcomes. 2-stage seemingly unrelated bivariate probit models were developed to jointly model the survival and neurological outcomes. We adjusted for the clustering effects of country variance in all models.Results
40,160 OHCA cases met the inclusion criteria. There were 5356 OHCA cases (13.3%) with initial shockable rhythm and 33,974 (84.7%) with initial non-shockable rhythm. After adjustment of baseline and prehospital characteristics, OHCA with initial shockable rhythm (odds ratio/OR = 6.10, 95% confidence interval/CI = 5.06–7.34) and subsequent conversion to shockable rhythm (OR = 2.00,95%CI = 1.10–3.65) independently predicted better survival-to-hospital-discharge outcomes. Subsequent shockable rhythm conversion significantly improved survival-to-admission, discharge and post-arrest overall and cerebral performance outcomes in the multivariate logistic regression and 2-stage analyses.Conclusion
Initial shockable rhythm was the strongest predictor for survival. However, conversion to subsequent shockable rhythm significantly improved post-arrest survival and neurological outcomes. This study suggests the importance of early resuscitation efforts even for initially non-shockable rhythms which has prognostic implications and selection of subsequent post-resuscitation therapy. 相似文献6.

Background
Among patients who survive after out-of-hospital cardiac arrest (OHCA), a large proportion are recruited from cases witnessed by the Emergency Medical Service (EMS), since the conditions for success are most optimal in this subset.Aim
To evaluate outcome after EMS-witnessed OHCA in a 20-year perspective in Sweden, with the emphasis on changes over time and factors of importance.Methods
All patients included in the Swedish Cardiac Arrest Register from 1990 to 2009 were included.Results
There were 48,349 patients and 13.5% of them were EMS witnessed. There was a successive increase in EMS-witnessed OHCA from 8.5% in 1992 to 16.9% in 2009 (p for trend < 0.0001). Among EMS-witnessed OHCA, the survival to one month increased from 13.9% in 1992 to 21.8% in 2009 (p for trend < 0.0001). Among EMS-witnessed OHCA, 51% were found in ventricular fibrillation, which was higher than in bystander-witnessed OHCA, despite a lower proportion with a presumed cardiac aetiology in the EMS-witnessed group.Among EMS-witnessed OHCA overall, 16.0% survived to one month, which was significantly higher than among bystander-witnessed OHCA.Independent predictors of a favourable outcome were: (1) initial rhythm ventricular fibrillation; (2) cardiac aetiology; (3) OHCA outside home and (4) decreasing age.Conclusion
In Sweden, in a 20-year perspective, there was a successive increase in the proportion of EMS-witnessed OHCA. Among these patients, survival to one month increased over time. EMS-witnessed OHCA had a higher survival than bystander-witnessed OHCA. Independent predictors of an increased chance of survival were initial rhythm, aetiology, place and age. 相似文献7.

Objective
The objective of this study was to explore the types of patient safety events that take place during pediatric out-of-hospital cardiac arrest resuscitation.Methods
Retrospective medical record review from a single large urban EMS system of EMS-treated pediatric (< 18 years of age) out-of-hospital cardiac arrests (OHCA) occurring between 2008 and 2011. A chart review tool was developed for this project and each chart was reviewed by a multidisciplinary review panel. Safety events were identified in the following clinical domains: resuscitation; assessment, impression/diagnosis, and clinical decision making; airway/breathing; fluids and medications; procedures; equipment; environment; and system.Results
From a total of 497 critical transports during the study period, we identified 35 OHCA cases (7%). A total of 87% of OHCA cases had a safety event identified. Epinephrine overdoses were identified in 31% of the OHCA cases, most of which were 10-fold overdoses. Other medication errors included failure to administer epinephrine when indicated and administration of atropine when not indicated. In 20% of OHCA cases, 3 or more intubation attempts took place or intubation attempts were ultimately not successful. Lack of end-tidal C02 use for tube confirmation was also common. The most common arrest algorithm errors were placing an advanced airway too early (before administration of epinephrine) and giving a medication not included in the algorithm, primarily atropine, both occurring in almost 1/3 of cases.Conclusions
Safety events were common during pediatric OHCA resuscitation especially in the domains of medications, airway/breathing, and arrest algorithms. 相似文献9.

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10.

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11.

Background
Previous studies on cardiac arrest in mountainous areas were focused on environmental features such as altitude and temperature. However, those are limited to factors affecting the prognosis of patients after cardiac arrest. We analyzed the cardiac arrests in national or provincial parks located in the mountains and determined the factors affecting the prognosis of patients after cardiac arrest.Methods
This study included all emergency medical service (EMS) treated patients over the age of 40 experiencing out-of-hospital cardiac arrests (OHCAs) of presumed cardiac etiology during exercise, between January 2012 and December 2015. The main focus of interest was the location of cardiac arrest occurrence (national mountain parks and provincial parks vs. other sites). The main outcome was survival to discharge and multivariable logistic regression was performed to adjust for possible confounding effects.Results
A total 1835 patients who suffered a cardiac arrest while exercising were included. From these, 68 patients experienced cardiac arrest in national or provincial parks, and 1767 occurred in other locations. The unadjusted and adjusted ORs (95% CI) for a good cerebral performance scale (CPC) were 0.09 (0.01–0.63) and 0.08(0.01–0.56), survival discharges were 0.13(0.03–0.53) and 0.11 (0.03–0.48).Conclusions
Cardiac arrests occurring while exercising in the mountainous areas have worse prognosis compared to alternative locations. 相似文献12.

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13.

Introduction
Extracorporeal life support (ECLS) has been reported to be more effective than conventional cardiopulmonary resuscitation (CPR). In ECLS, a shorter time from arrival to implantation of extracorporeal membrane oxygenation (ECMO; door-to-ECMO) time was predicted to be associated with better survival rates. This study aimed to examine the impact of the physician-based emergency medical services (P-EMS) using a rapid response car (RRC) on door-to-ECMO time in patients with out-of-hospital cardiac arrest (OHCA).Methods
In this retrospective cohort study, adult patients with OHCA who were admitted to a Japanese tertiary care hospital from April 2012 to December 2016 and underwent venoarterial ECMO were included. Patients were either transferred by emergency medical service (EMS only group) or RRC (RRC group). Primary outcome was door-to-ECMO time. Wilcoxon rank-sum test was used to compare the outcome between the two groups.Results
A total of 34 patients were included in this study, and outcome data were available for all patients. The door-to-ECMO time was significantly shorter in the RRC group than in the EMS only group (median, 23 min vs. 36 min; P = 0.006). Additionally, the RRC was also associated with earlier successful intubation and intravenous adrenaline administration.Conclusion
The physician-based RRC system was associated with a shorter door-to-ECMO time and successful advanced procedures in prehospital settings. Combination of the RRC system with ECLS may lead to better outcomes in patients with OHCA. 相似文献14.

Background
The aim of this study was to investigate whether the 1-year survival rate of out-of-hospital cardiac arrest (OHCA) patients with malignancy was different from that of those without malignancy.Methods
All adult OHCA patients were retrospectively analyzed in a single institution for 6 years. The primary outcome was 1-year survival, and secondary outcomes were sustained return of spontaneous circulation (ROSC), survival to hospital admission, survival to discharge and discharge with a good neurological outcome (CPC 1 or 2). Kaplan-Meier survival analysis and Cox proportional hazard regression analysis were performed to test the effect of malignancy.Results
Among 341 OHCA patients, 59 patients had malignancy (17.3%). Sustained ROSC, survival to admission, survival to discharge and discharge with a good CPC were not different between the two groups. The 1-year survival rate was lower in patients with malignancy (1.7% vs 11.4%; P = 0.026). Kaplan-Meier survival analysis revealed that patients with malignancy had a significantly lower 1-year survival rate when including all patients (n = 341; P = 0.028), patients with survival to admission (n = 172, P = 0.002), patients with discharge CPC 1 or 2 (n = 18, P = 0.010) and patients with discharge CPC 3 or 4 (n = 57, P = 0.008). Malignancy was an independent risk factor for 1-year mortality in the Cox proportional hazard regression analysis performed in patients with survival to admission and survival to discharge.Conclusions
Although survival to admission, survival to discharge and discharge with a good CPC rate were not different, the 1-year survival rate was significantly lower in OHCA patients with malignancy than in those without malignancy. 相似文献15.

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16.

Background
Repeated administration of epinephrine is associated with unfavorable cerebral outcome after out-of-hospital cardiac arrests (OHCA), but the timing of epinephrine administration has not been considered.Aim
The aim of the study was to analyze the effects of repeated epinephrine administration after OHCA on favorable cerebral function coded by cerebral performance categories (CPC 1–2).Methods
A nationwide, retrospective, population-based observational study was conducted by using Utstein-style data between 2010 and 2012 in Japan. The total of 11,876 cardiogenic and witnessed OHCA were stratified into 3 categories by the number of times epinephrine was administered (single, double, and three or more). In addition, the time elapsed between the emergency call and the initial epinephrine administration was divided into 3 time intervals (5 to 20 min for the early administration group [EAG], 21 to 26 min for the intermediate administration group [IAG], and 27 to 60 min for the late administration group [LAG]). The primary endpoint was CPC 1–2 at 1 month after cardiac arrest. A multivariable logistic regression was used for analysis.Results
Achievement of CPC 1–2 at 1 month was 4.8% for single, 2.4% for double, and 1.7% for three or more administered doses. For single and three or more administrationConclusion
Repeated epinephrine administration improved CPC 1–2 outcome when epinephrine was administrated within 20 min after an emergency call for witnessed cardiogenic OHCA. 相似文献17.
Aim
The aim of this investigation was to estimate and contrast the global incidence and outcome of out-of-hospital cardiac arrest (OHCA) to provide a better understanding of the variability in risk and survival of OHCA.Methods
We conducted a review of published English-language articles about incidence of OHCA, available through MEDLINE and EmBase. For studies including adult patients and both adult and paediatric patients, we used Utstein data reporting guidelines to calculate, summarize and compare incidences per 100,000 person-years of attended OHCAs, treated OHCAs, treated OHCAs with a cardiac cause, treated OHCA with ventricular fibrillation (VF), and survival-to-hospital discharge rates following OHCA.Results
Sixty-seven studies from Europe, North America, Asia or Australia met inclusion criteria. The weighted incidence estimate was significantly higher in studies including adults than in those including adults and paediatrics for treated OHCAs (62.3 vs 34.7; P < 0.001); and for treated OHCAs with a cardiac cause (54.6 vs 40.8; P = 0.004). Neither survival to discharge rates nor VF survival to discharge rates differed statistically significant among studies. The incidence of treated OHCAs was higher in North America (54.6) than in Europe (35.0), Asia (28.3), and Australia (44.0) (P < 0.001). In Asia, the percentage of VF and survival to discharge rates were lower (11% and 2%, respectively) than those in Europe (35% and 9%, respectively), North America (28% and 6%, respectively), or Australia (40% and 11%, respectively) (P < 0.001, P < 0.001).Conclusions
OHCA incidence and outcome varies greatly around the globe. A better understanding of the variability is fundamental to improving OHCA prevention and resuscitation. 相似文献18.

Backgrounds
In Japan, ambulance staffing for cardiac arrest responses consists of a 3-person unit with at least one emergency life-saving technician (ELST). Recently, the number of ELSTs on ambulances has increased since it is believed that this improves the quality of on-scene care leading to better outcomes from out-of-hospital cardiac arrest (OHCA). The objective of this study was to evaluate the association between the number of on-scene ELSTs and OHCA outcome.Methods
This was a prospective cohort study of all bystander-witnessed OHCA patients aged ≥18 years in Osaka City from January 2005 to December 2007 using on an Utstein-style database. The primary outcome measure was one-month survival with favorable neurological outcome defined as a cerebral performance category ≤2. Multivariable logistic regression model were used to assess the contribution of the number of on-scene ELSTs to the outcome after adjusting for confounders.Results
Of the 2408 bystander-witnessed OHCA patients, one ELST group was present in 639 (26.5%), two ELST were present in 1357 (56.4%), and three ELST group in 412 (17.1%). The three ELST group had a significantly higher rate of one-month survival with favorable neurological outcome compared with the one ELST group (8.0% versus 4.5%, adjusted OR 2.26, 95% CI 1.27–4.04), while the two ELST group did not (5.4% versus 4.5%, adjusted OR 1.34, 95% CI 0.82–2.19).Conclusions
Compared with the one on-scene ELST group, the three on-scene ELST group was associated with the improved one-month survival with favorable neurological outcome from OHCA in Osaka City. 相似文献19.

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20.
