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.

Purpose: The effects of amiodarone and lidocaine on the return of spontaneous circulation (ROSC), relative to time to treatment in out of hospital cardiac arrest (OHCA) patients is unknown. We conducted a post-hoc analysis of the Resuscitation Outcomes Consortium Amiodarone, Lidocaine, Placebo (ROC ALPS) randomized trial examining the association of time to treatment with ROSC at emergency department (ED) arrival. Method: In the ROC ALPS trial, adults with non-traumatic OHCA with initial VF/pVT after ≥ 1 shock were randomized to receive amiodarone, lidocaine or placebo. We used logistic regression to examine the association of time to treatment (911 call to study drug administration interval) with ROSC at ED arrival. Results: Overall, 1112 (36.7%) patients had ROSC at ED arrival. Time to treatment data were available for 2994 (99%) of the patients. The proportion of patients with ROSC at ED arrival decreased as time to drug administration increased, in amiodarone (OR 0.92, 95% CI 0.90-0.94 per min increase), lidocaine (OR 0.95, 95% CI: 0.93-0.96) and placebo (OR 0.95, 95% CI: 0.93-0.96) arms. The odds of ROSC at ED in the amiodarone group (versus placebo) changed in relation to the time of drug administration (OR 0.96, 95% CI: 0.93-0.99). With short times to drug administration, ROSC was higher in amiodarone versus placebo recipients, whereas ROSC was higher with placebo at later times. Comparing lidocaine to placebo, ROSC rate increased at all times (OR 1.29, 95% CI: 1.07-1.59); there was no time to drug administration effect (OR 1.00, 95% CI: 0.97-1.03). Among all patients, survival at hospital discharge was 21.0%, 24.4%, and 23.7% for placebo, amiodarone and lidocaine respectively. Conclusion: Amiodarone’s efficacy in restoring ROSC declined with longer duration of arrest, potentially due to its adverse hemodynamic effects. Overall, amiodarone and lidocaine had similar effects on mortality; in this study, ROSC at ED arrival trend did not reflect the overall survival rate
