Introduction Long pauses without chest compressions (CC) have been identified in CPR provided by EMS professionals for out-of-hospital cardiac arrest (OOHCA). The 2005 AHA ECC CPR guidelines emphasize CC. The 2005 AHA Basic Life Support (BLS) for Healthcare Professionals (HCP) course introduced a training method with more CPR skills practice during the DVD based course. The purpose of this before/after study was to determine whether CC rates increased after introduction of the 2005 course. Methods This urban EMS system has 400 cardiac etiology OOHCA events annually. A convenience sample of 49 continuous electronic ECG recordings of VF patients was analyzed with the impedance channel of the LIFEPAK 12 (Physio-Control, Redmond WA) and proprietary software. A trained researcher verified the automated analysis. Each CC during the resuscitation attempt and pauses in CC before and after the first defibrillation shock were noted. The time of return of spontaneous circulation (ROSC) was determined by medical record review and onset of regular electrical activity without CC. Medical records were reviewed for outcome to hospital discharge. The EMS patient care protocol for VF was changed on July 1, 2006 to comply with the 2005 AHA ECC guidelines. Cases were grouped by the OOHCA date: 9/2004 to 12/31/2006 (pre) and 7/1/2006 to 4/21/2007 (post). EMS personnel began taking the 2005 BLS for HCP course during spring 2006. Monthly courses over 3 years will recertify 1500 personnel. Results 29 cases were analyzed from the pre group and 20 from the post group. Compressions per minute increased from a mean (±SD) of 47 ± 16 pre to 75 ± 33 post (P < 0.01). The mean count of shocks given per victim decreased from 4.5 ± 4.0 pre to 2.8 ± 1.8 post (P < 0.04). The CC pause before the first shock was unchanged (23.6 ± 18.4 seconds to 22.1 ± 17.9). but the CC pause following that shock decreased significantly from 48.7 ± 63.2 to 11.8 ± 22.5 (p=0.008). Rates of ROSC (55% pre, 50% post) and survival to discharge (15% pre, 13% post) were similar. Conclusion Following introduction of the 2005 BLS for HCP course and the EMS protocol change, the quality of CPR delivered to victims of OOHCA improved significantly compared with pre-2006 CPR. The sample size was too small to detect differences in survival rates.

Our aim was to compare the outcomes of Impella with extracorporeal life support (ECLS) in patients with post-cardiac arrest cardiogenic shock (CS) complicating acute myocardial infarction (AMI). This was a retrospective study of patients resuscitated from out of hospital cardiac arrest (OHCA) with post-cardiac arrest CS following AMI (May 2015 to May 2020). Patients were supported either with Impella 2.5/CP or ECLS. Outcomes were compared using propensity score-matched analysis to account for differences in baseline characteristics between groups. 159 patients were included (Impella, n = 105; ECLS, n = 54). Hospital and 12-month survival rates were comparable in the Impella and the ECLS groups (p = 0.16 and p = 0.3, respectively). After adjustment for baseline differences, both groups demonstrated comparable hospital and 12-month survival (p = 0.36 and p = 0.64, respectively). Impella patients had a significantly greater left ventricle ejection-fraction (LVEF) improvement at 96 h (p < 0.01 vs. p = 0.44 in ECLS) and significantly fewer device-associated complications than ECLS patients (15.2% versus 35.2%, p < 0.01 for relevant access site bleeding, 7.6% versus 20.4%, p = 0.04 for limb ischemia needing intervention). In subgroup analyses, Impella was associated with better survival in patients with lower-risk features (lactate < 8.6 mmol/L, time from collapse to return of spontaneous circulation < 28 min, vasoactive score < 46 and Horowitz index > 182). In conclusion, the use of Impella 2.5/CP or ECLS in post-cardiac arrest CS after AMI was associated with comparable adjusted hospital and 12-month survival. Impella patients had a greater LVEF improvement than ECLS patients. Device-related access-site complications occurred more frequently in patients with ECLS than Impella support.

Background Survival rates after in-hospital cardiac arrest have not improved markedly despite improvements in technology and resuscitation training. Objectives To investigate clinical variables that influence return of spontaneous circulation and survival to discharge after in-hospital cardiac arrest. Methods An Utstein-style resuscitation template was implemented in a 750-bed hospital. Data on 158 events were collected from January 2004 through November 2004. Significant variables were analyzed by using a multiple logistic regression model. Results Of the 158 events, 128 were confirmed cardiac arrests. Return of spontaneous circulation occurred in 69 cases (54%), and the patient survived to discharge in 41 (32%). An initial shockable rhythm was present in 42 cases (33%), with a return of spontaneous circulation in 32 (76%) and survival to discharge in 24 (57%). An initial nonshockable rhythm was present in the remaining 86 cases (67%), with a return of spontaneous circulation in 37 (43%) and survival to discharge in 17 (20%). Witnessed or monitored arrests (P=.006), time to arrival of the cardiac arrest team (P=.002), afternoon shift (P=.02), and initial shockable rhythm (P=.005) were independently associated with return of spontaneous circulation. Location of patient in a critical care area (P=.002), initial shockable rhythm (P&lt;.001), and length of resuscitation (P=.02) were independently associated with survival to hospital discharge. Conclusions The high rate of survival to discharge after cardiac arrest is attributed to extensive education and the incorporation of semiautomatic external defibrillators into basic life support management.

Introduction: Understanding the key factors which affect out hospital cardiac arrest (OHCA) outcomes is essential in order to promote patient treatment. The main objective of this research was to describe the correlations between the capnographic values obtained during the first minute of monitoring on cardiopulmonary resuscitation, assisted by basic life-support units, with the results as return of spontaneous circulation (ROSC) and alive hospital admission. The secondary objectives were to describe the sociodemographic characteristics of the patients assisted, and to analyze any correlations between receiving basic life-support units and/or defibrillation prior to the arrival of basic life-support units, and the results of the cardiopulmonary resuscitation maneuvers. Methods: A prospective, descriptive, observational study of adult non-traumatic out hospital cardiac arrest patients was conducted. The patients were initially assisted by basic life-support units on the island of Mallorca, with one minute of initial capnography monitoring. Results: From July 2018 to March 2020, fifty-nine patients meeting the inclusion criteria were assisted, 76% were men and their mean age was 64.45 (±15.07) years old. The number of emergency lifesaving technicians who participated in the study was 58, they had a mean work experience of 14.05 (±6.7) years. Thirty-seven (63.7%) patients underwent basic life-support by bystanders and in 91.5% of cases the semi-automatic external defibrillator was used. Capnometry values during the first minute were obtained in 34 (58.6%) patients, their mean values were 22 (±19.07) mmHg, 35.5% of patients had values <10 mmHg. In 25.4% of the patients, spontaneous circulation returned during cardiopulmonary resuscitation, and 18.6% were admitted to hospital alive. Conclusion: No correlations were found between initial capnography values scoring above or below 10 mmHg and survival, however, basic life-support maneuvers, and defibrillation by bystanders and first responders, did correlate with survival rates. The average patient assisted in out of hospital cardiac arrest by the basic life-support units sampled was an adult male aged over 65 years.

Introduction: Between 1980 and 2008, survival rates following an out-of-hospital cardiac arrest (OHCA) have remained unchanged, averaging 7.6%. Despite the use of new and emerging technologies, new medications, and automated external defibrillators, survival remains low. Recently, a new focus in cardiopulmonary resuscitation (CPR) has shown dramatic improvements in survival post OHCA. This new model, called pit-crew CPR, focuses on minimizing interruptions in chest compressions and has each team member playing a specific role in the resuscitation, akin to the pit-crew of a car race. Certain districts in the United States and Canada have adopted the pit-crew, or a similar, high quality, maximum time-on-chest CPR model, with much success. We aim to determine whether the pit-crew model of CPR improves survival following OHCA in Saskatoon, SK. Methods: In Saskatoon, EMS and Fire crews respond to OHCAs and have been exclusively using the pit-crew model of CPR since Jan 1st, 2015. This study is a before and after retrospective chart analysis, comparing two groups - pre and post implementation of the pit-crew CPR model. The primary outcome is survival to hospital discharge post OHCA. Secondary outcomes include survival to admission and any return of spontaneous circulation (as per the Utstein definition). The inclusion criteria are patients >18 years old with a witnessed OHCA of presumed cardiac origin who receive CPR by EMS/Fire within the Saskatoon Ambulance service (MD Ambulance) catchment area. Patients were excluded if the OHCA was unwitnessed, or if there was a presumed non-cardiac cause for the arrest, e.g. trauma. Results: In the pre-pit-crew model cohort, between Jan 1st, 2011 and Sept 31st, 2014, 455 OHCAs were analyzed. In this cohort 10.5% survived to discharge, 31.9% survived to admission and ROSC was achieved in 39% of cases. The percentage of patients with initial rhythms of VF/VT, asystole or PEA were 28.5% (26%), 41.5% (1%) and 23.6% (10%) respectively, with survival to discharge shown in parentheses. The post-pit-crew cohort is still in the data collection phase. Conclusion: Our pre-pit crew cohort data has been collected and analyzed. With ongoing data acquisition for the post-pit crew cohort, we hope to have the full data set complete by the end of 2018. It will be at that time when we are able to determine whether the pit-crew model of CPR improves survival to discharge following OHCA in Saskatoon.

Abstract Backgroun:This study proposed an algorithm to improve resuscitation outcomes in the emergency department (ED) for patients with traumatic out-of-hospital cardiac arrest (TOHCA). We also performed a retrospective chart review of patient outcomes before and after implementing the algorithm and sought to define factors that might influence patient outcomes.Methods: In September 2018, we implemented an algorithm for patients with TOHCA. This algorithm rapidly identifies possible causes of TOHCA and recommends appropriate interventions. We retrospectively reviewed the outcomes of all patients with TOHCA during a 5-year period and compared the results before and after the implementation of the algorithm.Results:After this algorithm was implemented, the use of the ED interventions of blood transfusion, placement of a large-bore central venous catheter, and thoracostomy increased significantly. Return of spontaneous circulation (ROSC), hospital admission, and survival rates also increased (before vs. after: ROSC: 23.6% vs. 41.5%, P = 0.035; hospital admission: 18.2% vs. 24.6%, P = 0.394; survival: 0.0% vs. 4.6%, P = 0.107). Admitted patients exhibited a higher end-tidal CO2 level than nonadmitted patients [admitted vs. nonadmitted: 41.5 (33.3–52.0) vs. 12.0 (7.5–18.8), P = 0.001].Conclusion:Our algorithm prioritizes the three major treatable causes of TOHCA: impedance of venous return, hypovolemia, and hypoxia. We found that ROSC, hospital admission, and survival rates increased with the increasing implementation of the ED interventions recommended by the algorithm.

Background: Out-of-hospital cardiac arrest is an important cause that leads to hospital admission and death. Improving lay people’s knowledge and skills in basic life support (BLS) may lead to reduced death associated with out-of-hospital cardiac arrest. “BLS NU KKU” is a BLS training program developed from up-to-date literature as a smartphone application used to train lay people in the community. Objective: To evaluate BLS-related knowledge and skills of participants before and after BLS training. Materials and Methods: A one group pretest-posttest design was used to implement the present study in Khon Kaen, Thailand. Participants were 350 individuals age 18 and older. An 8-hour BLS training session was offered to 10 groups of 35 participants over the period of 10 months between November 2018 and August 2019. Self-administered questionnaires were used to assess BLS knowledge and Cardiopulmonary resuscitation (CPR) skills. Results: The mean score for BLS-related knowledge significantly increased after the BLS training (mean = 15.05, SD = 2.51) compared to the scores before the training (mean = 10.47, SD = 3.43) (p<0.05). BLS skills improved from 0% to 100% (p<0.001) will all skills rated with mostly “excellent” and “good”. Satisfaction with the training program was also rated mostly with “excellent” and “good”. Conclusion: The BLS training program effectively improved participants’ knowledge and skills for basic life support. This program should be disseminated to train lay people in other settings.

Introduction: Out-of-hospital cardiac arrest (OOHCA) victims are increasing, but emergency medical service system (EMSS) is not ready for them in Korea. A previous randomized, controlled clinical trial has suggested that vasopressin followed epinephrine was superior to epinephrine in patients with asystole. According to the Korean national registry of OOHCA, patients with asystole were more than two thirds of them. In Korean EMSS, no drugs are permitted to administer in the prehospital phase by law. Thereafter epinephrine or vasopressin cannot be administered until patients are transported to emergency departments (EDs). This study was to evaluate whether the combined administration of vasopressin and epinephrine in ED for OOHCA patients would increase the return of spontaneous circulation (ROSC) and survival discharge. Methods: From October 2007 to May 2008, we changed the CPR protocol in adult, nontraumatic OOHCA that 40 U of vasopressin was administered as soon as possible after the first dose of epinephrine (the after group). Cardiac arrest data were collected using the Utstein template. Data from January to September 2007, when vasopressin has not been used, were also collected for comparative analysis (the before group). These two groups were compared in terms of ROSC, and survival discharge Results: There were 45 and 50 patients in the before and after groups, respectively. There was no significant differences in the initial ECG rhythm of asystole (67% vs 78%), witnessed arrest (73% vs 72%), bystander CPR (16% vs 10%), time from collapse to BLS time (6 min vs 8.5 min), and time from collapse to study drugs (23 min vs 26.5 min). The rate of sustained ROSC was similar between the before and after groups (53% vs 48%, P=0.604) as was the survival discharge (27% vs 14%, P=0.123). Conclusions: Vasopressin with administerd with epinephrine does not increase the rate of ROSC nor the survival discharge.

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.

Abstract Background Refractory out of hospital cardiac arrest (OHCA) is associated with extremely poor outcomes. However, in selected patients extracorporeal cardiopulmonary resuscitation (eCPR) may be an effective rescue therapy, allowing time treat reversible causes. The primary goal was to estimate the potential future caseload of eCPR at historically 'low-volume' extracorporeal membrane oxygenation (ECMO) centres. Methods A 3-year observational study of OHCA presenting to the Emergency Department (ED of an urban referral centre without historical protocolised use of eCPR. Demographics and standard Utstein outcomes are reported. Further, an a priori analysis of each case for potential eCPR eligibility was conducted. A current eCPR selection criteria (from the 2-CHEER study) was used to determine eligibly. Results In the study window 248 eligible cardiac arrest cases were included in the OHCA registry. 30-day survival was 23.4% (n=58). The mean age of survivors was 55.4 years. 17 (6.8%) cases were deemed true refractory arrests and fulfilled the 2-CHEER eligibility criteria. The majority of these cases presented within “office hours” and no case obtained a return of spontaneous circulation standard advanced life support. Conclusions In this contemporary OHCA registry a significant number of refractory cases were deemed potential eCPR candidates reflecting a need for future interdisciplinary work to support delivery of this therapy.
