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.

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4.

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5.

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6.

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7.

Introduction
Analysis of modern military conflicts suggests that airway compromise remains the second leading cause of preventable death of combat fatalities. This study compares outcomes of combat casualties that received prehospital airway interventions, specifically bag valve mask (BVM) ventilation, cricothyrotomy, and supraglottic airway (SGA) placement. The goal is to compare the effectiveness of airway management strategies used in the military pre-hospital setting.Methods
This retrospective chart review of 1267 US Army medical evacuation patient care records, compared outcomes of casualties that received prehospital advanced airway interventions. The patients consisted of US military injured in Operation Enduring Freedom January 2011–March 2014. Compared outcomes consisted of vent-, ICU-, and hospital-free days.Results
Those with SGA placement experienced fewer vent-free days, ICU-free days, and hospital-free days compared to BVM and cricothyrotomy patients. The groups did not significantly differ in rates of 30-day survival. The odds for survival were not significantly higher for BVM versus SGA patients (OR 1.5, 95% CI 0.2–9.8), cricothyrotomy versus SGA patients (OR 3.9, 95% CI 0.6–24.9), or cricothyrotomy versus BVM patients (OR 2.7, 95% CI 0.5–13.8) in a logistic regression model adjusting for GCS.Conclusion
This study supports prehospital BVM ventilation as a possible alternative to cricothyrotomy as there was no difference in measured outcomes between the groups. It further cautions against SGA use in the prehospital combat setting due to higher morbidity demonstrated by fewer ventilator, hospital, and ICU free days than those receiving cricothyrotomy or BVM ventilation. There was no difference in 30-day survival between the groups. 相似文献8.
Conversion to shockable rhythms during resuscitation and survival for out-of hospital cardiac arrest

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9.
Background
A great number of studies have been conducted to examine the relationship between nurse staffing and patient outcomes. However, none of the reviews have rigorously assessed the evidence about the effect of nurse staffing on nurse outcomes through meta-analysis.Purpose
The purpose of this review was to systematically assess empirical studies on the relationship between nurse staffing and nurse outcomes through meta-analysis.Methods
Published peer-reviewed articles published between January 2000 and November 2016 were identified in CINAHL, PubMed, PsycINFO, Cochrane Library, EBSCO, RISS, and DBpia databases.Findings
This meta-analysis showed that greater nurse-to-patient ratio was consistently associated with higher degree of burnout among nurses (odds ratio: 1.07; 95% confidence interval [CI]: 1.04–1.11), increased job dissatisfaction (odds ratio: 1.08; 95% CI: 1.04–1.11), and higher intent to leave (odds ratio: 1.05; 95% CI: 1.02–1.07). With respect to needlestick injury, the overall effect size was 1.33 without statistical significance.Discussion
The study findings demonstrate that higher nurse-to-patient ratio is related to negative nurse outcomes. Future studies assessing the optimal nurse-to-patient ratio level in relation to nurse outcomes are needed to reduce adverse nurse outcomes and to help retain nursing staff in hospital settings. 相似文献10.

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11.

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12.

Objective
Prehospital personnel who lack advanced airway management training must rely on basic techniques when transporting unconscious trauma patients. The supine position is associated with a loss of airway patency when compared to lateral recumbent positions. Thus, an inherent conflict exists between securing an open airway using the recovery position and maintaining spinal immobilization in the supine position. The lateral trauma position is a novel technique that aims to combine airway management with spinal precautions. The objective of this study was to compare the spinal motion allowed by the novel lateral trauma position and the well-established log-roll maneuver.Methods
Using a full-body cadaver model with an induced globally unstable cervical spine (C5-C6) lesion, we investigated the mean range of motion (ROM) produced at the site of the injury in six dimensions by performing the two maneuvers using an electromagnetic tracking device.Results
Compared to the log-roll maneuver, the lateral trauma position caused similar mean ROM in five of the six dimensions. Only medial/lateral linear motion was significantly greater in the lateral trauma position (1.4 mm (95% confidence interval [CI] 0.4, 2.4 mm)).Conclusions
In this cadaver study, the novel lateral trauma position and the well-established log-roll maneuver resulted in comparable amounts of motion in an unstable cervical spine injury model. We suggest that the lateral trauma position may be considered for unconscious non-intubated trauma patients. 相似文献13.
Objective
To compare closed and open endotracheal suction system in relation to ventilator-associated pneumonia in adult intensive care unit patientsMethod
Systematic review.Results
Of the 18 eligible studies identified through the search strategy, only 5 studies were included in the review. The two endotracheal suction systems show no differences in the incidence of ventilator-associated pneumonia (5 trials: odds ratio [OR], 0.92; Mantel-Haenszel [M-H], fixed; 95% confidence interval [95%CI], 0.72-1.18) or mortality rates (3 trials: OR, 0.89; M-H, fixed; 95%CI, 0.62-1.28).Conclusions
Results from 5 studies showed that suctioning with either closed or open endotra-cheal suction did not have an effect on the incidence of ventilator-associated-pneumonia or mortality rates. Therefore, more rigorous and large-scale research is needed for further evaluation. 相似文献14.

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15.

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16.

Purpose
The aim of this study was to assess the usefulness of the Global Registry of Acute Coronary Events (GRACE) risk score in predicting in-hospital mortality and neurological outcome of patients resuscitated after out-of-hospital cardiac arrest (OHCA).Methods
We retrospectively analyzed the data of patients admitted to our hospital between October 2009 and October 2015 with OHCA and shockable initial cardiac rhythm who were resuscitated via conventional cardiopulmonary resuscitation. We calculated the GRACE risk score on admission and assessed its usefulness in predicting in-hospital mortality and neurological outcome.Results
Among 91 patients, 42 (46%) had acute myocardial infarction (AMI), 19 (21%) died in-hospital, and 52 (57%) had favorable neurological outcome. Among all the study patients, GRACE risk score was lower in survivors than in non-survivors (median 211 [interquartile range 176–240] vs. 266 [219–301], p < 0.001, respectively) and in favorable than in unfavorable neurological outcome group (202 [167–237] vs. 242 [219–275], p < 0.001, respectively). Multivariate analysis showed significant association between GRACE risk score and favorable neurological outcome (odds ratio, 0.975; 95% confidence interval, 0.961–0.990). Areas under receiver-operating characteristic curves, that describe the accuracy of GRACE risk score in predicting in-hospital mortality and favorable neurological outcome, were both 0.79.Conclusion
GRACE risk score may predict the in-hospital mortality and neurological outcome associated with resuscitated patients with OHCA and shockable initial cardiac rhythm, regardless of the cause of arrest. 相似文献17.

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18.

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19.

Adult out-of-hospital cardiac arrest (OHCA) patients with presumed cardiac etiology (2012 to 2014) were analyzed, excluding patients not-resuscitated, occurred in ambulance/medical/nursing facility, unknown STI or extremely longer STI (> 60 min), and unknown outcomes. STI was classified into short (0.0–3.9 min), middle (4.0–7.9 min), long (8.0–11.9 min), and very-long (12.0–59.9 min), respectively. The end point was a good cerebral performance category (CPC) 1 or 2. Multivariable logistic regression by STI group (reference = short) was performed to calculate adjusted odds ratios (AORs) with 95% confidence intervals (95% CIs) for outcomes with or without interaction term (STI 1 prehospital return of spontaneous circulation, (PROSC)).Results
Of 79,832 OHCA patients, 41,054 cases were analyzed; good CPC in the short (3.0%), middle (3.2%), long (3.0%), and very-long (2.9%) STI groups were similar, respectively (p = 0.55). The AORs (95% CI) for good CPC in the final model without interaction term were 0.74 (0.58–0.95) for the middle, 0.51 (0.39–0.67) for the long, and 0.45 (0.33–0.61) for the very-long STI group (reference = short STI). The AORs in PROSC group were 1.18 (0.97–1.44) for middle STI group, 0.72 (0.57–0.92) for long group, and 0.56 (0.42–0.77) for very-long group. The AORs in non-PROSC group were 1.22 (1.06–1.40) for middle STI group, 0.82 (0.70–0.96) for long group, and 0.70 (0.57–0.85) for very-long group.Conclusion
The middle STI (4–7 min) was associated with the highest odds of neurological recovery for patients who could not be restored in the field. The STI may be a clinically useful predictor of good neurology outcome in victims of cardiac arrest. 相似文献20.
