Hospital Cardiac Arrest

The management of out-of-hospital, atraumatic cardiac arrest has changed over the past decade. This case details the evidence-based changes in care that optimize the chance of neurologically intact survival. The key factors include immediate, continuous, high-quality cardiopulmonary resuscitation with minimal interruptions, early defibrillation, and the use of capnography to assess resuscitative efforts. The orchestration of resuscitative efforts is a bundle of care that must all be met to provide the patient the best chance of survival. Furthermore, this case illustrates the key points of postarrest care and touches on termination of resuscitation. This chapter examines the case of emergency medical services call for an unresponsive patient in cardiac arrest on arrival.

Abstract Background The effects of prehospital epinephrine administration in combination with the quality of cardiopulmonary resuscitation (CPR) on neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm remains unclear. Purpose This study aimed to elucidate the effects of prehospital epinephrine administration in combination with the quality of CPR on neurologically intact survival in OHCA patients with non-shockable rhythm. Methods We analysed 118,732 adult OHCA patients with non-shockable rhythm from the All-Japan OHCA registry between 2011 and 2016 (29,989 emergency medical service [EMS]-witnessed arrests with EMS-initiated CPR [high-quality CPR] and 88,743 bystander-witnessed arrests with bystander-initiated CPR continued by EMS providers [low-quality CPR]). Patients who achieved prehospital return of spontaneous circulation without prehospital epinephrine administration were excluded. The primary outcome measure was 1-month neurologically intact survival (cerebral performance category 1 or 2; CPC 1–2). Time from collapse to prehospital epinephrine administration for patients with prehospital epinephrine administration, or to hospital arrival for patients without prehospital epinephrine administration was calculated and adjusted collectively in multivariate logistic regression analysis for 1-month CPC 1–2. Results Multivariate logistic regression analysis revealed that the time from collapse to prehospital epinephrine administration or to hospital arrival was negatively associated with 1-month CPC 1–2 (adjusted odds ratio [OR] 0.95 per 1-minute increment, 95% confidence interval [CI] 0.94–0.96). Compared with bystander-witnessed arrests without prehospital epinephrine administration, EMS-witnessed arrests with or without prehospital epinephrine administration were significantly associated with increased chances of 1-month CPC 1–2 (adjusted OR 2.04, 95% CI 1.50–2.75 and adjusted OR 1.97, 95% CI 1.57–2.48, respectively). Prehospital epinephrine administration was significantly associated with an increased chance of 1-month CPC 1–2 among bystander-witnessed arrests (adjusted OR 1.57, 95% CI 1.24–1.98), but not among EMS-witnessed arrests. EMS-witnessed arrests without prehospital epinephrine administration were significantly associated with an increased chance of 1-month CPC 1–2 compared with bystander-witnessed arrests with prehospital epinephrine administration (adjusted OR 1.26, 95% CI 1.01–1.56). Conclusions High-quality CPR is crucial for increasing neurologically intact survival in OHCA patients with non-shockable rhythm. The additional beneficial effects of prehospital epinephrine administration were observed only among OHCA patients with low-quality CPR.

Abstract Background Data on the effects of witness status and time from an emergency call to initiation of cardiopulmonary resuscitation (CPR) by emergency medical service (EMS) providers on neurological outcome in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm according to the first documented rhythm are limited. Purpose We aimed to determine the effects of witness status and time from an emergency call to CPR initiation by EMS providers on neurologically intact survival in OHCA patients according to the type of non-shockable rhythm (pulseless electrical activity [PEA] and asystole). Methods We analysed the records of 583,431 adult OHCA patients with non-shockable rhythm (191,905 bystander-witnessed arrest and 391,526 unwitnessed arrest). Data were derived from the prospectively recorded All-Japan OHCA registry between 2011 and 2016. Call to EMS-CPR interval was defined as the time from an emergency call to CPR initiation by EMS providers. The primary outcome was 1-month neurologically intact survival (cerebral performance category 1 or 2; CPC 1–2) and secondary outcome was presence of PEA. Results The rates of 1-month CPC 1–2 were 1.21% (2,326/191,905) for bystander-witnessed arrest and 0.24% (959/391,526) for unwitnessed arrest. When divided into 4 groups based on witness status and initial documented rhythm, these rates were 2.42% (1,869/77,190) for bystander-witnessed arrest with PEA (group A), 0.40% (457/114,715) for bystander-witnessed arrest with asystole (group B), 1.51% (679/44,926) for unwitnessed arrest with PEA (group C) and 0.08% (280/346,600) for unwitnessed arrest with asystole (group D). Multivariate logistic regression analysis revealed each 1-min delay of Call to EMS-CPR interval to be significantly associated with decreased chances of 1-month CPC 1–2 for groups A, B and D (adjusted odds ratio [OR]: 0.95, 0.91 and 0.96, respectively; 95% confidence interval [CI]: 0.93–0.96, 0.88–0.94 and 0.93–0.99, respectively). However, for group C, there was no significant relationship between these variables (adjusted OR: 1.00; 95% CI: 0.98–1.02). The proportion of PEA was 40.2% (77,190/191,905) for bystander-witnessed arrest and 11.5% (44,926/391,526) for unwitnessed arrest. Multivariate logistic regression analysis revealed that, as Call to EMS-CPR interval lengthened (per 1-min delay), the number of OHCA patients with PEA decreased for bystander-witnessed arrest (adjusted OR: 0.94; 95% CI: 0.93–0.94) and for unwitnessed arrest (adjusted OR: 0.96; 95% CI: 0.96–0.97). Conclusions The 1-month CPC 1–2 rate differed by witness status and initial documented rhythm in OHCA patients with non-shockable rhythm. Shortening of Call to EMS-CPR interval is crucial for improving 1-month CPC 1–2 rate and sustaining PEA, particularly in bystander-witnessed arrest.

High-quality cardiopulmonary resuscitation (CPR) is a key element in out-of-hospital cardiac arrest (OHCA) resuscitation. Mechanical CPR devices have been developed to provide uninterrupted and high-quality CPR. Although human studies have shown controversial results in favor of mechanical CPR devices, their application in pre-hospital settings continues to increase. There remains scant data on the pre-hospital use of mechanical CPR devices in Asia. Therefore, we conducted a retrospective cohort study between September 2018 and August 2020 in an urban city of Taiwan to analyze the effects of mechanical CPR devices on the outcomes of OHCA; the primary outcome was attainment of return of spontaneous circulation (ROSC). Of 552 patients with OHCA, 279 received mechanical CPR and 273 received manual CPR, before being transferred to the hospital. After multivariate adjustment for the influencing factors, mechanical CPR was independently associated with achievement of any ROSC (OR = 1.871; 95%CI:1.195–2.930) and sustained (≥24 h) ROSC (OR = 2.353; 95%CI:1.427–3.879). Subgroup analyses demonstrated that mechanical CPR is beneficial in shorter emergency medical service response time (≤4 min), witnessed cardiac arrest, and non-shockable cardiac rhythm. These findings support the importance of early EMS activation and high-quality CPR in OHCA resuscitation.

Background: Despite advances in out- of- hospital resuscitation practices, the prognosis of most patients after a cardiac arrest remains poor. The long term outcomes of patients successfully resuscitated from cardiac arrest are often complicated by neurological dysfunction. Therapeutic hypothermia has significantly improved neurological outcomes in patients successfully resuscitated from out- of- hospital cardiac arrests. The objective of this study was to look into the neurological outcomes in inpatients after successful cardiopulmonary resuscitation (CPR) in a university hospital setting. Methods: This was a retrospective observational study of 68 adult patients who experienced cardiac or respiratory arrest over an 18 month period at a metropolitan teaching hospital with dedicated, trained code teams. Arrests that occurred in the Emergency Department, Critical Care Units or Operating Rooms were excluded. Results: Of the 68 consecutive patients included in this study, 53% were resuscitated successfully. However, only 12 (18%) survived to discharge from the hospital and only 6 (10%) were discharged with intact neurological status. The initial survival was better in patients who received prompt CPR and in those with less co - morbidities. Pulseless electrical activity (PEA) or asystole were the most common rhythms (47% of the arrests). Most patients who survived and were neurologically intact had PEA (67%). We believe that most PEA arrests were more likely severe hypotension with the inability to palpate a pulse rather than true PEA. The mean time to defibrillation for all patients with an initial shockable rhythm (n=5) was 8.2 minutes. Patients who had an initial shockable rhythm and survived to discharge were shocked within 1 minute (n=2). Conclusion: Despite advances in critical care, survival from inpatient cardiopulmonary arrest to neurologically intact discharge remains poor. Therapeutic hypothermia should be expanded to those resuscitated from in - hospital cardiopulmonary arrest to determine if neurological outcomes would improve.

Background: Prolonged conventional cardiopulmonary resuscitation (C-CPR) is associated with a poor prognosis in out-of-hospital cardiac arrest (OHCA) patients. Extracorporeal cardiopulmonary resuscitation (E-CPR) has been utilized as a rescue strategy for patients with cardiac arrest unresponsive to C-CPR. However, the indication and optimal duration to switch from C-CPR to E-CPR are not well established. In addition, the opportunities to develop teamwork skills and expertise to mitigate risks are few. We thus developed the implementation protocol for the E-CPR simulation program, and investigated whether the faster deployment of extracorporeal membrane oxygenation (ECMO) improves the neurological outcome in patients with refractory OHCA. Methods: A total of 42 consecutive patients (age 58±16 years, male ratio 90%, and initial shockable rhythm 64%) received E-CPR (3% of OHCA) during the study period. Among them, 32 (76%) were deployed ECMO during the pre-intervention time period (Pre: from January 2012 to September 2017), whereas 10 (24%) were deployed during the post-intervention time period (Post: October 2017 to May 2019). We compared the door to E-CPR time, collapse to E-CPR time, 30-day mortality, and favorable neurological outcome (Cerebral Performance Categories 1, 2) between the two periods. Results: There was no significant difference in age, the rates of male sex and shockable rhythm, and the time form collapse to emergency room admission between the two periods. The door to E-CPR time and the collapse to E-CPR time were significantly shorter in the post-intervention period compared to the pre-intervention period (Pre: 39 min [IQR; 30-50] vs. Post: 29 min [IQR; 22-31]; P=0.007, Pre: 76 min [IQR; 58-87] vs. Post: 59 min [IQR; 44-68]; P=0.02, respectively). The 30-day mortality was similar between the two periods (Pre: 88% vs. Post: 80%; P=0.6). In contrast, the rate of favorable neurological outcome at the time of discharge was significantly higher in post-intervention period (Pre: 0% vs. Post: 20%; P=0.01) compared to the pre-intervention period. Conclusion: A comprehensive simulation-based training for E-CPR seems to improve the neurological outcome in patients with refractory OHCA patients.

INTRODUCTION: The role of chest compression fraction (CCF) in resuscitation of shockable out-of-hospital cardiac arrest (OHCA) is uncertain. We evaluated the relationship between CCF and clinical outcomes in a secondary analysis of the Resuscitation Outcomes Consortium (ROC) PRIMED trial. METHODS: We included OHCA patients from the ROC PRIMED trial who suffered cardiac arrest prior to EMS arrival, presented with a shockable rhythm, and had cardiopulmonary resuscitation (CPR) process data for at least one shock. We used multivariable logistic regression adjusting for Utstein variables, CPR metrics of compression rate and perishock pause, and ROC site to determine the relationship between CCF and survival to hospital discharge, return of spontaneous circulation (ROSC), and neurologically intact survival defined with Modified Rankin Score (MRS) ≤ 3. Due to potential confounding between CCF and cases that achieved early ROSC, we also performed an analysis restricted to patients without ROSC in the first 10 minutes of EMS resuscitation. RESULTS: Among the 2,558 eligible patients, median (IQR) age was 65 (54, 76) years, 76.9% were male, and mean (SD) CCF was 0.70 (0.15). Compared to the reference group (CCF < 0.60), the odds ratio (OR) for survival was 0.57 (95%CI: 0.42, 0.78) for CCF 0.60-0.79 and 0.32 (95%CI: 0.22, 0.48) for CCF ≥0.80. Results were similar for outcomes of ROSC and neurologically intact survival. Conversely, when restricted to the cohort who did not achieve ROSC during the first 10 minutes (n=1,660), the relationship between CCF and survival was no longer significant. Compared to the reference group (CCF < 0.60), the OR for survival was 0.85 (95 %CI: 0.58, 1.26) for CCF 0.60-0.79 and OR 0.87 (95%CI: 0.58, 1.36) for CCF ≥0.80. CONCLUSIONS: In this observational cohort study of OHCA patients presenting in a shockable rhythm, CCF when adjusted for Utstein predictors, CPR metrics and ROC site was paradoxically associated with lower odds of survival. The relationship between CCF and clinical outcomes was null in a sensitivity analysis restricted to patients without ROSC in the first 10 minutes. CCF is a complex measure and taken by itself may not be a consistent predictor of clinical outcome.

Background Outcomes of patients from out‐of‐hospital cardiac arrest (OHCA) vary widely globally because of differences in prehospital systems of emergency care. National efforts had gone into improving OHCA outcomes in Singapore in recent years including community and prehospital initiatives. We aimed to document the impact of implementation of a national 5‐year Plan for prehospital emergency care in Singapore on OHCA outcomes from 2011 to 2016. Methods and Results Prospective, population‐based data of OHCA brought to Emergency Departments were obtained from the Pan‐Asian Resuscitation Outcomes Study cohort. The primary outcome was Utstein (bystander witnessed, shockable rhythm) survival‐to‐discharge or 30‐day postarrest. Mid‐year population estimates were used to calculate age‐standardized incidence. Multivariable logistic regression was performed to identify prehospital characteristics associated with survival‐to‐discharge across time. A total of 11 465 cases qualified for analysis. Age‐standardized incidence increased from 26.1 per 100 000 in 2011 to 39.2 per 100 000 in 2016. From 2011 to 2016, Utstein survival rates nearly doubled from 11.6% to 23.1% ( P =0.006). Overall survival rates improved from 3.6% to 6.5% ( P <0.001). Bystander cardiopulmonary resuscitation rates more than doubled from 21.9% to 56.3% and bystander automated external defibrillation rates also increased from 1.8% to 4.6%. Age ≤65 years, nonresidential location, witnessed arrest, shockable rhythm, bystander automated external defibrillation, and year 2016 were independently associated with improved survival. Conclusions Implementation of a national prehospital strategy doubled OHCA survival in Singapore from 2011 to 2016, along with corresponding increases in bystander cardiopulmonary resuscitation and bystander automated external defibrillation. This can be an implementation model for other systems trying to improve OHCA outcomes.
