RESUMO
BACKGROUND: It is unclear how invasive resuscitative protocols may impact the time-dependent prognosis of out-of-hospital cardiac arrest (OHCA) resuscitations, or the relationship between intra-arrest transport and outcomes. METHODS: We performed a secondary analysis of the Prague OHCA Study, which randomized refractory OHCAs to "invasive" (intra-arrest transport for possible ECPR initiation) vs. "standard" resuscitation strategies (predominantly performed on-scene). Between groups, we compared outcomes of the initial resuscitation and 180- and 30-day favourable neurological outcomes (CPC 1-2), and within categories based on resuscitation duration (collapse-to-ROSC/ECPR interval). We plotted the dynamic probability of favourable outcomes with increasing durations of unsuccessful resuscitation. RESULTS: Among invasive and standard groups, respectively: 34/124 (27%) vs. 58/132 (44%) had sustained ROSC (difference -17%, 95%CI -5.0, -28); 38/124 (31%) vs. 24/132 (18%) had 30-day favourable neurological outcomes (difference 12%; 95%CI 2.0, 23); and 39/124 (31%) vs. 29/132 (22%) had 180-day favourable neurological outcomes (difference 9.5%; 95%CI -1.3, 20). For favourable outcome cases: standard group resuscitation durations were right-skewed within the first 60 minutes; for the invasive group the distribution was bimodal, extending to 77 minutes. For invasive- and standard-treated cases, the probability of favourable outcomes among those in refractory arrest at 30 minutes was 28% and 7.6%, respectively; declining to 0% at 77 and 60 minutes. CONCLUSION: In comparison to standard resuscitation, invasive strategy cases had fewer achieve sustained ROSC, however improved overall 30-day favourable neurological outcomes. While standard resuscitation yield was limited to <60 minutes, invasive protocols offer a second extended window of potential successful resuscitation.
RESUMO
OBJECTIVE: To analyze if the implementation of a multidisciplinary extracorporeal cardiopulmonary resuscitation (ECPR) program in a tertiary hospital in Spain is feasible and could yield survival outcomes similar to international published experiences. DESIGN: Retrospective observational cohort study. SETTING: One tertiary referral university hospital in Spain. PATIENTS: All adult patients receiving ECPR between January 2019 and April 2023. INTERVENTIONS: Prospective collection of variables and follow-up for up to 180 days. MAIN VARIABLES OF INTEREST: To assess outcomes, survival with good neurological outcome defined as a Cerebral Performance Categories scale 1-2 at 180 days was used. Secondary variables were collected including demographics and comorbidities, cardiac arrest and cannulation characteristics, ROSC, ECMO-related complications, survival to ECMO decannulation, survival at Intensive Care Unit (ICU) discharge, survival at 180 days, neurological outcome, cause of death and eligibility for organ donation. RESULTS: Fifty-four patients received ECPR, 29 for OHCA and 25 for IHCA. Initial shockable rhythm was identified in 27 (50%) patients. The most common cause for cardiac arrest was acute coronary syndrome [29 (53.7%)] followed by pulmonary embolism [7 (13%)] and accidental hypothermia [5 (9.3%)]. Sixteen (29.6%) patients were alive at 180 days, 15 with good neurological outcome. Ten deceased patients (30.3%) became organ donors after neuroprognostication. CONCLUSIONS: The implementation of a multidisciplinary ECPR program in an experienced Extracorporeal Membrane Oxygenation center in Spain is feasible and can lead to good survival outcomes and valid organ donors.
RESUMO
Introduction: This study aimed to explore the views and perceptions of Advanced Life Support (ALS) practitioners in two South African provinces on initiating, withholding, and terminating resuscitation in OHCA. Methodology: Semi-structured one-on-one interviews were conducted with operational ALS practitioners working within the prehospital setting in the Western Cape and Free State provinces. Recorded interviews were transcribed and subjected to inductive-dominant, manifest content analysis. After familiarisation with the data, meaning units were condensed, codes were applied and collated into categories that were then assessed, reviewed, and refined repeatedly. Results: A total of 18 ALS providers were interviewed. Five main categories were developed from the data analysis: 1) assessment of prognosis, 2) internal factors affecting decision-making, 3) external factors affecting decision-making, 4) system challenges, and 5) ideas for improvement. Factors influencing the assessment of prognosis were history, clinical presentation, and response to resuscitation. Internal factors affecting decision-making were driven by emotion and contemplation. External factors affecting decision-making included family, safety, and disposition. System challenges relating to bystander response and resources were identified. Ideas for improvement in training and support were brought forward. Conclusion: Many factors influence OHCA decision-making in the Western Cape and Free State provinces, and numerous system challenges have been identified. The findings of this study can be used as a frame of reference for prehospital emergency care personnel and contribute to the development of context-specific guidelines.
RESUMO
BACKGROUND AND AIMS: Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide, with cardiovascular disease (CVD) being a key risk factor. This study aims to investigate disparities in patient/OHCA characteristics and survival after OHCA among patients with versus without depression. METHODS: This is a retrospective cohort study using data from the AmsteRdam REsuscitation Studies (ARREST) registry from 2008-2018. History of comorbidities, including depression, was obtained from the patient's general practitioner. OHCA survival was defined as survival at 30 days post-OHCA or hospital discharge. Logistic regression models were used to obtain crude and adjusted odds ratios (ORs) for the association between depression and OHCA survival and possible effect modification by age, sex, and comorbidities. The potential mediating effects of initial heart rhythm and provision of bystander cardiopulmonary resuscitation were explored. RESULTS: Among 5,594 OHCA cases, 582 individuals had pre-existing depression. Patients with depression had less favourable patient and OHCA characteristics and lower odds of survival after adjustment for age, sex, and comorbidities (OR 0.65, 95% CI 0.51-0.82), with similar findings by sex and age groups. The association remained significant among the Utstein comparator group (OR 0.63, 95% CI 0.45-0.89) and patients with return of spontaneous circulation (OR 0.60, 95% CI 0.42-0.85). Initial rhythm and bystander cardiopulmonary resuscitation partially mediated the observed association (by 27% and 7%, respectively). CONCLUSIONS: OHCA patients with depression presented more frequently with unfavourable patient and OHCA characteristics and had reduced chances of survival. Further investigation into potential pathways is warranted.
RESUMO
Introduction: The use of extracorporeal cardiopulmonary resuscitation (ECPR) for refractory cardiac arrest is increasing globally. However, providing equity of access to all patients is challenging, and to date, access has been limited to inner city areas surrounding major hospitals. To increase the availability of ECPR in our jurisdiction, we sought to train pre-hospital physicians with no experience in extracorporeal membrane oxygenation cardiopulmonary resuscitation (ECPR). To enable this, we sort to develop and teach a syllabus that would provide novice ECPR providers the skill to perform ECPR safely and effectively in the pre-hospital environment. Methods: This training programme consisted of 11 pre-hospital physicians and six critical care paramedics. All participants had no prior hospital experience instituting or managing ECPR patients. The training programme was multimodal utilising a porcine model of heart failure to teach time pressured dynamic physiological troubleshooting, cadaver labs to teach cannulation, didactic teaching and simulation. Key knowledge and skill domains were identified. Each learning framework was built upon with a final focus on integrating all skill domains required to successfully initiate ECPR. Results: The training program was completed from February 2022 to August 2023. Knowledge progression was assessed at key stages via written and practical examination. Each participant demonstrated clear knowledge and skill progression at the key stages of the training programme. At the end of the training programme, participants met the pre-defined standards to progress to ECPR provision in the pre-hospital environment. Conclusion: We present a training program for novice ECPR providers performing ECPR in the pre-hospital setting. The outcomes of this training program can provide a training framework for both novices, low volume ECMO centres and pre-hospital clinicians.
RESUMO
OBJECTIVES: There is no sufficient data to provide a clear picture of out-of-hospital cardiac arrest (OHCA) across Türkiye. This study is the first to present the prognostic outcomes of OHCA cases and the factors associated with these outcomes. MATERIALS AND METHODS: The study was conducted in a prospective, observational, multicenter design under the leadership of the Emergency Medicine Association of Turkey Resuscitation Study Group. OHCA cases aged 18 years and over who were admitted to 28 centers from Türkiye were included in the study. Survived event, return of spontaneous circulation (ROSC), survival to hospital discharge, and neurological outcome at discharge were investigated as primary outcomes. RESULTS: One thousand and three patients were included in the final analysis. 61.1% of the patients were male, and the average age was 67.0 ± 15.2. Cardiopulmonary resuscitation (CPR) was performed on 86.5% of the patients in the prehospital period by emergency medical service, and bystander CPR was performed on only 2.9% by nonhealth-care providers. As a result, the survived event rate was found to be 6.9%. The survival rate upon hospital discharge was 4.4%, with 2.7% of patients achieving a good neurological outcome upon discharge. In addition, the overall ROSC and sustained ROSC rates were 45.2% and 33.4%, respectively. In the multiple logistic regression analysis, male gender, initial shockable rhythm, a shorter prehospital duration of CPR, and the lack of CPR requirement in the emergency department were determined to be independent predictors for the survival to hospital discharge. CONCLUSION: Compared to global data, survival to hospital discharge and good neurological outcome rates appear to be lower in our study. We conclude that this result is related to low bystander CPR rates. Although not the focus of this study, inadequate postresuscitative care and intensive care support should also be discussed in this regard. It is obvious that this issue should be carefully addressed through political moves in the health and social fields.
RESUMO
BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is associated with higher survival for out-of-hospital cardiac arrest, but whether its association with survival differs by patients' sex and race and ethnicity is less clear. METHODS: Within a large US registry, we identified 623 342 nontraumatic out-of-hospital cardiac arrests during 2013 to 2022 for this observational cohort study. Using hierarchical logistic regression, we examined whether there was a differential association between bystander CPR and survival outcomes by patients' sex and race and ethnicity, overall and by neighborhood strata. RESULTS: Mean age was 62.1±17.1 years, and 35.9% were women. Nearly half of patients (49.8%) were non-Hispanic White; 20.6% were non-Hispanic Black; 7.3% were Hispanic; 2.9% were Asian; and 0.4% were Native American. Overall, 58 098 (9.3%) survived to hospital discharge. Although bystander CPR was associated with higher survival in each race and ethnicity group, the association of bystander CPR compared with patients without bystander CPR in each racial and ethnic group was highest in individuals who were White (adjusted odds ratio [OR], 1.33 [95% CI, 1.30-1.37]) and Native American (adjusted OR, 1.40 [95% CI, 1.02-1.90]) and lowest in individuals who were Black (adjusted OR, 1.09 [95% CI, 1.04-1.14]; Pinteraction<0.001). The adjusted OR for bystander CPR compared with those without bystander CPR for Hispanic patients was 1.29 (95% CI, 1.20-1.139), for Asian patients, it was 1.27 (95% CI, 1.12-1.42), and for those of unknown race, it was 1.31 (95% CI, 1.25-1.36). Similarly, bystander CPR was associated with higher survival in both sexes, but its association with survival was higher in men (adjusted OR, 1.35 [95% CI, 1.31-1.38]) than women (adjusted OR, 1.15 [95% CI, 1.12-1.19]; Pinteraction<0.001). The weaker association of bystander CPR in Black individuals and women was consistent across neighborhood race and ethnicity and income strata. Similar results were observed for the outcome of survival without severe neurological deficits. CONCLUSIONS: Although bystander CPR was associated with higher survival in all patients, its association with survival was weakest for Black individuals and women with out-of-hospital cardiac arrest.
RESUMO
Introduction: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) improves bystander CPR rates and survival outcomes. This study aimed to identify barriers to successful DA-CPR in patients with out-of-hospital cardiac arrest (OHCA). Methods: This retrospective observational study used data from a nationwide OHCA database from 2017 to 2021. Adult emergency medical services (EMS)-treated patients with OHCA with a presumed cardiac etiology were enrolled. The main exposure variable was compliance with DA-CPR. The primary outcome was good neurological recovery at hospital discharge. Multivariable logistic regression analysis was conducted to identify the major factors associated with unsuccessful DA-CPR with and without multiple imputations. Causal mediation analysis was conducted using witnessed status as a mediator. Results: In the final analysis, 49,165 patients with OHCA were included. A total of 36,865 (75.0%) patients successfully underwent DA-CPR. A higher proportion of good neurological recovery was observed in the successful DA-CPR group than in the non-successful DA-CPR group (P < 0.001). The following factors were identified as risk factors for unsuccessful DA-CPR: age > 65 years, male sex, OHCA occurring in a non-metropolitan area or private place, unwitnessed status, whether the bystander was a non-family member or non-cohabitant, female sex or had not received CPR training, and primary call dispatchers not receiving any first-aid training. Additional analyses after multiple imputations showed similar results. Mediation effect was significant for most risk factors for unsuccessful DA-CPR. Conclusions: Bystander characteristics (non-family member or non-cohabitant, female, and uneducated status for CPR) and primary call dispatchers not receiving first-aid training were identified as risk factors for unsuccessful DA-CPR.
RESUMO
Background: Defibrillation in the critical first minutes of out-of-hospital cardiac arrest (OHCA) can significantly improve survival. However, timely access to automated external defibrillators (AEDs) remains a barrier. Objectives: The authors estimated the impact of a statewide program for drone-delivered AEDs in North Carolina integrated into emergency medical service and first responder (FR) response for OHCA. Methods: Using Cardiac Arrest Registry to Enhance Survival registry data, we included 28,292 OHCA patients ≥18 years of age between 1 January 2013 and 31 December 2019 in 48 North Carolina counties. We estimated the improvement in response times (time from 9-1-1 call to AED arrival) achieved by 2 sequential interventions: 1) AEDs for all FRs; and 2) optimized placement of drones to maximize 5-minute AED arrival within each county. Interventions were evaluated with logistic regression models to estimate changes in initial shockable rhythm and survival. Results: Historical county-level median response times were 8.0 minutes (IQR: 7.0-9.0 minutes) with 16.5% of OHCAs having AED arrival times of <5 minutes (IQR: 11.2%-24.3%). Providing all FRs with AEDs improved median response to 7.0 minutes (IQR: 6.2-7.8 minutes) and increased OHCAs with <5-minute AED arrival to 22.3% (IQR: 16.4%-30.9%). Further incorporating optimized drone networks (326 drones across all 48 counties) improved median response to 4.8 minutes (IQR: 4.3-5.2 minutes) and OHCAs with <5-minute AED arrival to 56.3% (IQR: 46.9%-64.2%). Survival rates were estimated to increase by 34% for witnessed OHCAs with estimated drone arrival <5 minutes and ahead of FR and emergency medical service. Conclusions: Deployment of AEDs by FRs and optimized drone delivery can improve AED arrival times which may lead to improved clinical outcomes. Implementation studies are needed.
RESUMO
Aims: To describe and explore predictors of bystander defibrillation in Ireland during the period 2012 to 2020. To examine the relationship between bystander defibrillation and health system developments. Methods: National level Out of Hospital Cardiac Arrest (OHCA) registry data were interrogated, focusing on patients who had defibrillation performed. Bystander defibrillation (as compared to EMS initiated defibrillation) was the key outcome of concern. Logistic regression models were built and refined by fitting predictors, performing stepwise variable selection and by adding pairwise interactions that improved fit. Results: The data included 5,751 cases of OHCA where defibrillation was performed. Increasing year over time (OR 1.17, 95% CI 1.13, 1.21) was associated with increased adjusted odds of bystander defibrillation. Non-cardiac aetiology was associated with reduced adjusted odds of bystander defibrillation (OR 0.30, 95% CI 0.21, 0.42), as were increasing age in years (OR 0.99, 95% CI 0.987, 0.996) and night-time occurrence of OHCA (OR 0.67, 95% CI 0.53, 0.83). Six further variables in the final model (sex, call response interval, incident location (home or other), who witnessed collapse (bystander or not witnessed), urban or rural location, and the COVID period) were involved in significant interactions. Bystander defibrillation was in general less likely in urban settings and at home locations. Whilst women were less likely to receive bystander defibrillation overall, in witnessed OHCAs, occurring outside the home, in urban areas and outside of the COVID-19 period women were more likely, to receive bystander defibrillation. Conclusions: Defibrillation by bystanders has increased incrementally over time in Ireland. Interventions to address sex and age-based disparities, alongside interventions to increase bystander defibrillation at night, in urban settings and at home locations are required.
RESUMO
INTRODUCTION: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly being applied to patients with refractory cardiac arrest, but the survival rate to hospital discharge is only approximately 29%. Because ECPR requires intensive resources, it is important to predict outcomes. We therefore investigated the prognostic association between acute kidney injury (AKI) and ECPR to confirm the performance of AKI as a prognostic predictor of in-hospital mortality and neurological outcomes in ECPR. METHODS: We conducted a retrospective observational study on patients undergoing ECPR for cardiac etiology at Chonnam National University Hospital from 2015 to 2021. The group diagnosed with AKI in any KDIGO category within the first 48 h after ECPR was compared to that without AKI, and the primary outcome of the study was in-hospital mortality. RESULTS: Of 138 enrolled patients, 83 were studied. Hospital mortality occurred in 49 patients (59%), and 55 (66.3%) showed poor neurological outcomes. The AKI group displayed significantly elevated in-hospital mortality (77.8% vs 24.1%) and poor neurological outcomes (81.5% vs 37.9%) compared to the non-AKI group (p < 0.001). Regression analysis showed that AKI was associated with significantly higher rates of both in-hospital mortality (odds ratio (OR) range 10.75-12.88) and neurologic outcomes (OR range 5.9-6.22). CONCLUSIONS: There was a significant association of AKI with both in-hospital mortality and poor neurologic outcome in patients after ECPR, and AKI can be used as an early prognostic predictor in these patients.
RESUMO
AIM OF THE STUDY: We evaluated whether an artificial intelligence (AI)-driven robot cardiopulmonary resuscitation (CPR) could improve hemodynamic parameters and clinical outcomes. METHODS: We developed an AI-driven CPR robot which utilizes an integrated feedback system with an AI model predicting carotid blood flow (CBF). Twelve pigs were assigned to the AI robot group (n = 6) and the LUCAS 3 group (n = 6). They underwent 6 minutes of CPR after 7 minutes of ventricular fibrillation. In the AI robot group, the robot explored for the optimal compression position, depth and rate during the first 270-second period, and continued CPR with the optimal setup during the next 90-second period and beyond. The primary outcome was CBF during the last 90-second period. The secondary outcomes were coronary perfusion pressure (CPP), end-tidal carbon dioxide level (ETCO2) and return of spontaneous circulation (ROSC). RESULTS: The AI model's prediction performance was excellent (Pearson correlation coefficient = 0.98). CBF did not differ between the two groups [estimate and standard error (SE), -23.210 ± 20.193, P = 0.250]. CPP, ETCO2 level and rate of ROSC also did not show difference [estimate and SE, -0.214 ± 7.245, P = 0.976 for CPP; estimate and SE, 1.745 ± 3.199, P = 0.585 for ETCO2; 5/6 (83.3%) vs. 4/6 (66.7%), P = 1.000 for ROSC). CONCLUSION: This study provides proof of concept that an AI-driven CPR robot in porcine cardiac arrest is feasible. Compared to a LUCAS 3, an AI-driven CPR robot produced comparable hemodynamic and clinical outcomes.
RESUMO
Out-of-hospital cardiac arrest (OHCA) is associated with very poor outcomes. Extracorporeal cardiopulmonary resuscitation (eCPR) for selected patients is a potential therapeutic option for refractory cardiac arrest. However, randomised controlled studies applying eCPR after refractory OHCA have demonstrated conflicting results regarding survival and good functional neurological outcomes. eCPR is an invasive, labour-intensive, and expensive therapeutic approach with associated side-effects. A rapid monitoring device would be valuable in facilitating selection of appropriate patients for this expensive and complex treatment. To this end, rapid diagnosis of hyperfibrinolysis, or premature clot dissolution, diagnosed by viscoelastic testing might represent a feasible option. Hyperfibrinolysis is an evolutionary response to low or no-flow states. Studies in trauma patients demonstrate a high mortality rate in those with established hyperfibrinolysis upon emergency room admission. Similar findings have now been reported for the first time in OHCA patients. Hyperfibrinolysis upon admission diagnosed by rotational thromboelastometry was strongly associated with mortality and poor neurological outcomes in a small cohort of patients treated with extracorporeal membrane oxygenation.

In emergency situations, ensuring standardized cardiopulmonary resuscitation (CPR) actions is crucial. However, current automated external defibrillators (AEDs) lack methods to determine whether CPR actions are performed correctly, leading to inconsistent CPR quality. To address this issue, we introduce a novel method called deep-learning-based CPR action standardization (DLCAS). This method involves three parts. First, it detects correct posture using OpenPose to recognize skeletal points. Second, it identifies a marker wristband with our CPR-Detection algorithm and measures compression depth, count, and frequency using a depth algorithm. Finally, we optimize the algorithm for edge devices to enhance real-time processing speed. Extensive experiments on our custom dataset have shown that the CPR-Detection algorithm achieves a mAP0.5 of 97.04%, while reducing parameters to 0.20 M and FLOPs to 132.15 K. In a complete CPR operation procedure, the depth measurement solution achieves an accuracy of 90% with a margin of error less than 1 cm, while the count and frequency measurements achieve 98% accuracy with a margin of error less than two counts. Our method meets the real-time requirements in medical scenarios, and the processing speed on edge devices has increased from 8 fps to 25 fps.

Background: Cardiopulmonary resuscitation (CPR) is a crucial medical technique that is performed manually to preserve intact brain function. Early initiation of CPR manoeuvres and activation of the chain of survival are key factors in the prognosis of patients with cardiorespiratory arrest (CRA). Inadequacy in any step of CPR due to a lack of knowledge or skill is associated with a poor return of spontaneous circulation and a decreased survival rate. Objective: To assess the knowledge, attitude, practice, and factors associated with health towards CPR at Ayder Comprehensive Specialized Hospital 2023. Methods: Institution-based cross-sectional study was conducted to assess the knowledge, attitude, and practice of health professionals towards cardiopulmonary CPR in Ayder Comprehensive Specialized Hospital Of Tigray, Ethiopia from 1 May to 30 August 2023. Data were collected using structured questionnaires by Two BSC anaesthesia staff and One MSc. as supervisor. A stratified random sampling technique was used to select the study participants. The Data were entered and analyzed using SPSS version 23. Variables with P value less than 0.20 were fitted into multivariate logistic regression. Descriptive statistics such as frequencies, median, interquartile range, percentages, tables, graphs and charts were used to present the results. Result: A total of 262 Of 277 healthcare providers were included in the study, with a response rate of 93.3%. Knowledge, attitude, practice of health professionals towards CPR was 22.5%, 39% and 31.5%, respectively. MSc degree in level of education [adjusted odds ratio (AOR): 8.561 95% CI=2.109-34.746], CPR training (AOR: 2.157, 95%, 1.005, 4.631), and Work experience 6-10years and more than 10 (AOR =0.195, 95% CI, 0.071-0.539) and AOR =0.148 195 95% CI, 0.017, 1.285) were significantly associated with knowledge. The Anaesthetist and Medical doctors were 5.5 times (AOR, 5.50, 95% CI 1.263-23.93) and 2.125 times (AOR: 2.125, 95% CI, 0.865-5.216) respectively more likely to have favourable attitude than the midwives. Regarding to practice participants with CPR training (AOR: 1.804 95% CI=0.925-3.518), good knowledge (AOR: 2.766 95% CI=1.312-5.836) and favourable attitude (AOR: 1.931, 95% CI=0.995-3.749) were significantly associated with safe practice. Conclusion and recommendation: The overall level of health professionals, knowledge, attitude, practices, and factors associated towards CPR in Ayder Comprehensive Specialized Hospital at Tigray, Ethiopia were insufficient, favourable and safe enough. Regular CPR training is recommended to increase the knowledge, attitude, and practice of healthcare professionals towards CPR.
RESUMO
INTRODUCTION: The need for end-of-life care is common in intensive care units (ICUs). Although guidelines exist, little is known about actual end-of-life care practices in Hong Kong ICUs. The study aim was to provide a detailed description of these practices. METHODS: This prospective, multicentre observational sub-analysis of the Ethicus-2 study explored end-of-life practices in eight participating Hong Kong ICUs. Consecutive adult ICU patients admitted during a 6-month period with life-sustaining treatment (LST) limitation or death were included. Follow-up continued until death or 2 months from the initial decision to limit LST. RESULTS: Of 4922 screened patients, 548 (11.1%) had LST limitation (withholding or withdrawal) or died (failed cardiopulmonary resuscitation/brain death). Life-sustaining treatment limitation occurred in 455 (83.0%) patients: 353 (77.6%) had decisions to withhold LST and 102 (22.4%) had decisions to withdraw LST. Of those who died without LST limitation, 80 (86.0%) had failed cardiopulmonary resuscitation and 13 (14.0%) were declared brain dead. Discussions of LST limitation were initiated by ICU physicians in most (86.2%) cases. Shared decision-making between ICU physicians and families was the predominant model; only 6.0% of patients retained decision-making capacity. Primary medical reasons for LST limitation were unresponsiveness to maximal therapy (49.2%) and multiorgan failure (17.1%). The most important consideration for decision-making was the patient's best interest (81.5%). CONCLUSION: Life-sustaining treatment limitations are common in Hong Kong ICUs; shared decision-making between physicians and families in the patient's best interest is the predominant model. Loss of decision-making capacity is common at the end of life. Patients should be encouraged to communicate end-of-life treatment preferences to family members/surrogates, or through advance directives.
RESUMO
The American Heart Association (AHA), founded in 1924, is anchored in the core belief that scientific research can lead the way to better prevention, treatment, recovery, and ultimately a cure for cardiovascular disease. Historically, the association's involvement in international efforts centered on scientific cooperation. Activities mostly involved AHA leadership presenting at international scientific meetings and leaders from other countries sharing scientific and medical information at AHA meetings. Although the AHA's and American Stroke Association's international efforts have expanded substantially since those early days, global knowledge exchange remains the bedrock of its international endeavors. As the AHA turns 100, we reflect on the successful global efforts in prevention, resuscitation, global advocacy, quality improvement, and health equity that have guided the organization to a place of readiness for "advancing health and hope, for everyone, everywhere." Motivated by the enormous potential for population health gains in an aging world, the AHA is entering its second century with redoubled commitment to improving global cardiovascular and cerebrovascular health for all.
RESUMO
Background: Healthcare providers must possess the necessary knowledge and skills to perform effective cardiopulmonary resuscitation (CPR). In the event of cardiopulmonary arrest, basic life support (BLS) is the initial step in the life-saving process before the advanced CPR team arrives. BLS simulation training using manikins has become an essential teaching methodology in nursing education, enhancing newly employed nurses' knowledge and skills and empowering them to provide adequate resuscitation. Objective: This study aimed to evaluate the potential effect of BLS simulation training on knowledge and practice scores among newly employed nurses in Jordanian government hospitals. Methods: A total of 102 newly employed nurses were randomly assigned to two groups: the control group (n = 51) received standard training, and the experimental group (n = 51) received one full day of BLS simulation training. The training program used the American Heart Association (AHA)-BLS-2020 guidelines and integrated theoretical models such as Miller's Pyramid and Kolb's Cycle. Both groups were homogeneous in inclusion characteristics and pretest results. Knowledge and practice scores were assessed using 23 multiple-choice questions (MCQs). Data were analyzed using one-way repeated measures ANOVA. Results: The results indicated significant differences in knowledge scores, F(2, 182) = 58.514, p <0.001, and practice scores, F(2, 182) = 20.134, p <0.001, between the control and experimental groups at all measurement times: pretest, posttest 1, and posttest 2. Moreover, Cohen's d reflected the effectiveness of BLS simulation training as an educational module, showing a large effect (Cohen's d = 1.568) on participants' knowledge levels and a medium effect (Cohen's d = 0.749) on participants' practice levels. Conclusion: The study concludes that BLS simulation training using the AHA-BLS-2020 guidelines and integrating theoretical models such as Miller's Pyramid and Kolb's Cycle significantly improves knowledge and practice scores among newly employed nurses, proving highly effective in enhancing their competencies in performing CPR. Implementing BLS simulation training in nursing education programs can significantly elevate the proficiency of newly employed nurses, ultimately improving patient outcomes during cardiopulmonary arrest situations. This training approach should be integrated into standard nursing curricula to ensure nurses are well-prepared for real-life emergencies. Trial Registry Number: NCT06001879.
RESUMO
Background: This study aimed to compare the short-term outcomes of surgical treatment for acute type A aortic dissection between patients undergoing cardiopulmonary arrest at the time of entry into the operating room and patients who received successful preoperative cardiopulmonary resuscitation before entering the operating room or patients who had cardiopulmonary arrest on the operating room table after entering the operating room without cardiopulmonary arrest. In the present study, we focused on the circulatory status at the time of entering the operating room because it is economically and emotionally difficult to cease intervention once the patient has entered the operating room, where surgeons, anesthesiologists, nurses, and perfusionists are already present, all necessary materials are packed off and cardiopulmonary bypass have already been primed. Methods: Twenty (5.5%) of 362 patients who underwent surgical treatment for acute type A aortic dissection between January 2016 and March 2022 had preoperative cardiopulmonary arrest. To compare the early operative outcomes, the patients were divided into the spontaneous circulation group (n = 14, 70.0%) and the non-spontaneous circulation group (n = 6, 30.0%) based on the presence or absence of spontaneous circulation upon entering the operating room. The primary endpoint was postoperative 30-day mortality. The secondary endpoints included in-hospital complications and persistent neurological disorders. Results: Thirty-day mortality was 65% (n = 13/20) in the entire cohort; 50% (n = 7/14) in the spontaneous circulation group and 100% (n = 6/6) in the non-spontaneous circulation group. The major cardiopulmonary arrest causes were aortic rupture and cardiac tamponade (n = 16; 80.0%), followed by coronary malperfusion (n = 4; 20.0%). Seven patients (50.0%) survived in the spontaneous circulation group, and none survived in the non-spontaneous circulation group (P = .044). Five survivors walked unaided and were discharged home; the remaining two were comatose and paraplegic. Conclusions: The outcomes were extremely poor in patients with acute type A aortic dissection who had preoperative cardiopulmonary arrest and received ongoing cardiopulmonary resuscitation at entry into the operating room. Therefore, surgical treatment might be contraindicated in such patients.
