Purpose. The dynamic state of epinephrine (Ep) in the plasma of patients with out-of-hospital cardiac arrest (OHCA) remains unclear. The purpose of this study was to evaluate the relationship between the plasma levels of catecholamines (such as epinephrine (Ep), norepinephrine (Nep), and dopamine) and vasopressin (antidiuretic hormone (ADH)) and the acquisition of return of spontaneous circulation (ROSC) in OHCA patients. Methods. This was a prospective, observational clinical study. Patients with OHCA transferred to our hospital between July 2014 and July 2017 were enrolled. The levels of catecholamines and ADH in the plasma were measured using blood samples immediately obtained on arrival at our hospital and before the administration of Ep. Patients in whom Ep was already administered prior to obtaining blood samples were excluded. Patients were divided into two groups: with and without ROSC, that is, ROSC (+) and ROSC (−) groups, respectively. The plasma levels of these agents and the conditions of resuscitation were compared between the two groups. Results. A total of 96 patients with OHCA were analyzed. The ROSC (+) and ROSC (−) groups included 34 and 62 patients, respectively. There were no significant differences observed between the two groups in age, cause of cardiopulmonary arrest, and prehospital resuscitation time. The plasma levels of Ep and Nep were significantly lower in the ROSC (+) group than in the ROSC (−) group. However, there were no significant differences in the plasma levels of dopamine and ADH between the two groups. Conclusion. Increased levels of Ep in the plasma may not be associated with the acquisition of ROSC in patients with OHCA.

Purpose: The efficacy of epinephrine (Ep) administration to patients with cardiopulmonary arrest (CPA) remains controversial, and correlation between plasma levels of catecholamines and prognosis in CPA patients is unclear. The purpose of this study is to evaluate the importance of the plasma levels of catecholamines at the time of admission to the hospital prior to the administration of Ep in CPA patients. Methods: This was a prospective, observational clinical study, approved by the ethics committee of Gunma University Hospital. Patients with CPA transferred to our hospital were enrolled prospectively between July 2014 and July 2017. The levels of catecholamines (Ep, norepinephrine [NEp], and dopamine [DOA]) and vasopressin (antidiuretic hormone [ADH]) in the plasma were measured using blood samples obtained at the time of admission to our hospital (prior to the administration of Ep). Patients were divided into two groups: the return of spontaneous circulation (ROSC)(+) group and the ROSC(-) group. The levels of these agents in the plasma and the conditions of resuscitation were compared between these two groups. Results: Blood samples were obtained from 170 patients. In 48 patients, the cause of CPA was cardiogenic and Ep was not administered prior to admission to the hospital. The ROSC(+) and ROSC(-) groups included 14 and 34 patients, respectively. The frequency of prehospital defibrillation was significantly higher in the ROSC(+) group, whereas prehospital resuscitation time was significantly shorter in the ROSC(+) group. Moreover, the levels of Ep and NEp in the plasma were significantly lower in the ROSC(+) group. Conclusions: Increased levels of Ep in the plasma may not be associated with the acquisition of ROSC in patients with cardiogenic CPA.

Background: Early cardiopulmonary resuscitation (CPR) and early defibrillation are critical to survival from out-of-hospital cardiac arrest (OHCA). However, few studies have investigated the relationship between time interval from collapse to return of spontaneous circulation (ROSC) and neurologically intact survival. Methods: From the All-Japan OHCA Utstein Registry between 2005 and 2015, we enrolled adult patients achieving prehospital ROSC after witnessed OHCA, inclusive of arrest after emergency medical service responder arrival. The study patients were divided into two groups according to initial cardiac arrest rhythm (shockable versus non-shockable). The collapse-to-ROSC interval was calculated as the time interval from collapse to first achievement of prehospital ROSC. The primary endpoint was 30-day favorable neurological outcome after OHCA. Results: A total of 69,208 adult patients achieving prehospital ROSC after witnessed OHCA were enrolled; 23,017(33.3%) the shockable arrest group and 46,191 (66.7%) the non-shockable arrest group. The shockable arrest group compared with the non-shockable arrest group had significantly shorter collapse-to-ROSC interval (16±10 min vs. 20±13 min, P<0.001) and significantly higher frequency of the favorable neurological outcome (54.9% vs. 15.3%, P<0.001). Frequencies of the favorable neurological outcome after shockable OHCA decreased to 1.2% to 1.5% with every minute that the collapse-to-ROSC interval was delayed (78% at 1 minute of collapse, 68% at 10 minutes, 44% at 20 minutes, 34% at 30 minutes, 16% at 40 minutes, 4% at 50 minutes and 0% at 60 minutes, respectively, P<0.001), and those after non-shockable OHCA decreased to 0.8% to 1.8% with every minute that the collapse-to-ROSC interval was delayed (40% at 1 minute of collapse, 26% at 10 minutes, 11% at 20 minutes, 5% at 30 minutes, 2% at 40 minutes, 0% at 50 minutes and 0% at 60 minutes, respectively, P<0.001). Conclusions: Termination of the collapse-to-ROSC interval to achieve neurologically intact survival after witnessed OHCA was 50 minutes or longer irrespective of initial cardiac arrest rhythm (shockable versus non-shockable), although the neurologically intact survival rate was difference between the two groups.

Introduction: Time to return of spontaneous circulation (ROSC) is a more important predictor of neurologically intact survival than the presence of ROSC in patients with out-of-hospital cardiac arrest (OHCA). However, the differences in the relationship between time to ROSC and neurologically intact survival in patients with OHCA based on age is unclear. Hypothesis: We hypothesized that the impact of time to ROSC on neurologically intact survival differs according to age. Methods: We analyzed the data of 34,905 patients with OHCA (age ≥18 years) who exhibited prehospital ROSC from the prospectively recorded all-Japan OHCA registry (2011-2014). The primary outcome was neurologically intact survival at 1 month after OHCA (cerebral performance category [CPC] 1 or 2). Time to ROSC was defined as the interval from the initiation of cardiopulmonary resuscitation (CPR) by emergency medical service (EMS) providers to the achievement of ROSC. We categorized time to ROSC by every 4-min interval (2 cycles of CPR) from 1 to 32 min and ≥33 min, and age into 4 groups: 18-64, 65-74, 75-89, and ≥90 years. Results: The overall CPC 1-2 rate was 21.1% (7,353/34,905). Increasing time to ROSC (per min) was negatively associated with CPC 1-2 (adjusted odds ratio, 0.91; 95% confidence interval, 0.90-0.91). The CPC 1-2 rates decreased as time to ROSC increased in each age group: from 58.8% (1,247/2,122) in 1-4 min to 2.8% (7/246) in ≥33 min for patients aged 18-64 years, from 51.1% (721/1,410) in 1-4 min to 1.6% (4/244) in ≥33 min for 65-74 years, from 37.3% (765/2,051) in 1-4 min to 0.7% (4/539) in 29-32 min for 75-89 years, and from 23.4% (92/393) in 1-4 min to 0.2% (1/481) in 17-20 min for ≥90 years (all p for trend <0.001). Conclusions: The CPC 1-2 rates of patients aged 18-64 and 65-74 years were above the 1% futility rate when prehospital ROSC was achieved after prolonged CPR, ≥33 min from initiation by EMS providers. However, the CPC 1-2 rates were below the 1% futility rate when prehospital ROSC was achieved ≥29 min and ≥17 min for patients aged 75-89 years and ≥90 years, respectively.

Objective- In November 2005, updated resuscitation guidelines were introduced world-wide, and will be revised again in 2010. This study aims to determine how long it takes to implement new guidelines. Methods- This was a prospective observational study. From July 2005 to January 2008, we included all patients with a non traumatic out-of-hospital cardiac arrest. Ambulance paramedics sent all continuous ECG registrations with impedance signal by modem. We excluded ECGs from patients with Return Of Spontaneous Circulation at arrival, incomplete ECG registrations, ECGs with technical deficits or with continuous chest compressions. The same guidelines needed to be used in over 75% of the registration time in order to be labeled. We classified ECGs as guidelines 2000 if the c:v ratio was 15:2, shock blocks were present and there was rhythm analysis after each shock; guidelines 2005 if the c:v ratio was 30:2, a single shock protocol was used and chest compressions was immediately resumed after shock or rhythm analysis in a no shock scenario. We accepted 10% deviations in the amount of compressions (13–17 for 2000 guidelines, 27–33 for 2005). Results- Of the 1703 analyzable ECGs, we classified 827 (48.6%) as guidelines 2000 and 624 (36.6%) as guidelines 2005. In the remaining 252 ECGs (14.8%) 31 used guidelines 1992, 137 applied guidelines 2000 with c:v ratio of 30:2 and 84 did not show distinguishable guideline usage. Since the introduction in November 2005, it took 17 months to apply new guidelines in over 80% of the cases (figure 1 ). Conclusion- Guideline changes are slowly implemented by professionals. This needs to be taken in consideration when new guideline revisions are considered.

Aim: To evaluate the priority of coronary angiography (CAG) and therapeutic hypothermia therapy (TH) after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA). Patients and Methods: SOS-KANTO 2012 study is a prospective, multicenter (69 emergency hospitals) and observational study and includes 16,452 patients with OHCA. Among the cases with ROSC in that study, we intended for patients treated with both CAG and TH within 24 hours after arrival. Those patients were divided into two groups; patients in whom TH was firstly performed (TH group), and the others in whom CAG was firstly done (CAG group). We statistically compared the prognosis between the two groups. SPSS Statistics 22 (IBM, Tokyo, Japan) was used for the statistical analysis. Statistical significance was assumed to be present at a p value of less than 0.05. Result: 233 patients were applied in this study. There were 86 patients in the TH group (M/F: 74/12, mean age; 60.0±15.2 y/o) and 147 in the CAG group (M/F: 126/21, mean age: 63.4±11.1 y/o) respectively, and no significant differences were found in the mean age and M/F ratio between the two groups. The overall performance categories (OPC) one month after ROSC in the both groups were as follows; in the TH group, OPC1: 21 (24.4%), OPC2: 3 (3.5%), OPC3: 7 (8.1%), OPC4: 8 (9.3%), OPC5: 43 (50.0%), unknown: 4 (4.7%), and in the CAG group, OPC1: 38 (25.9%), OPC2: 13 (8.8%), OPC3: 15 (10.2%), OPC4: 18 (12.2%), OPC5: 57 (38.8%), unknown: 6 (4.1%). There were no significant differences in the prognosis one month after ROSC between the two groups. Conclusion: The results which of TH and CAG you give priority to over do not affect the prognosis in patients with OHCA.
