Knowledge and attitudes of physicians in Chile toward Do-Not-Attempt-Resuscitation orders: A cross-sectional nation-wide study.

Objective: Do-Not-Attempt-Resuscitation orders originated in the early 1960s with the establishment of advanced cardiopulmonary resuscitation. These orders aim to limit therapeutic efforts in cases where it may be futile. The decision not to resuscitate a patient is a process that involves a series of ethical, legal, and clinical considerations. Still, it also requires a process in which priority is given to the patients and their autonomy. The objective of this study was to describe the knowledge and attitudes of physicians working in Chile toward Do-Not-Attempt-Resuscitation orders. Methods: A cross-sectional study was conducted, in which a digital questionnaire was sent to physicians from different regions of Chile. Quantitative variables were analyzed using measures of central tendency and dispersion (e.g., median and interquartile range), while qualitative variables were evaluated using frequencies and percentages. Results: Four hundred and thirty-one physicians completed the survey. 85.4% were familiar with the ethical and legal guidelines for cardiopulmonary resuscitation and the rights and duties of the patient. 39.2% believed that patients should have the final decision Do-Not-Attempt-Resuscitation orders, especially if they themselves requested not to be resuscitated. 87.7% mentioned that the Do-Not-Attempt-Resuscitation orders should be reassessed if the patient's prognosis improves. In addition, it was found that the decision not to resuscitate was not always discussed with the patient or their family. Conclusions: The study revealed an ethical conflict regarding Do-Not-Attempt-Resuscitation orders and their management by Chilean physicians. Therefore, it is necessary to create recommendations and provide training to guide professionals in this process, which should also involve patients and their families.

Out of hospital cardiac arrest, first steps to know and follow in Mexico to have cardioprotected territories. A point of view of a group of experts / Paro cardiaco extrahospitalario, primeros pasos que se deben conocer y hacer en México para tener espacios cardioprotegidos. Punto de vista de un grupo de expertos

Abstract Sudden cardiac death is a common occurrence. Out-of-hospital cardiac arrest is a global public health problem suffered by ≈3.8 million people annually. Progress has been made in the knowledge of this disease, its prevention, and treatment; however, most events occur in people without a previous diagnosis of heart disease. Due to its multifactorial and complex nature, it represents a challenge in public health, so it led us to work in a consensus to achieve the implementation of cardioprotected areas in Mexico as a priority mechanism to treat these events. Public access cardiopulmonary resuscitation (CPR) and early defibrillation require training of non-medical personnel, who are usually the first responders in the chain of survival. They should be able to establish a basic and efficient CPR and use of the automatic external defibrillator (AED) until the emergency services arrive at the scene of the incident. Some of the current problems in Mexico and alternative solutions for them are addressed in the present work.

Resumen La muerte súbita cardíaca (SCD) es un acontecimiento común. El paro cardiaco extrahospitalario (OHCA) es un problema de salud pública mundial que sufren ≈3.8 millones de personas al año. Se ha avanzado en el conocimiento de esta enfermedad, su prevención y tratamiento, sin embargo, la mayoría de los eventos se producen en personas sin diagnóstico previo de cardiopatía. Debido a su carácter multifactorial y complejo, representa un reto en salud pública, lo que obliga a trabajar en un consenso para lograr la implementación de "Espacios Cardio protegidos" en México, como mecanismo prioritario de atención a estos eventos. La reanimación cardiopulmonar básica (RCPB) y la desfibrilación temprana de acceso público requieren de entrenamiento al personal no médico, que suelen ser los primeros respondientes para iniciar la cadena de la supervivencia. Ellos deberían instaurar una RCPB eficiente y el uso del desfibrilador automático externo (AED) hasta que lleguen al lugar del incidente los servicios de emergencias. El presente trabajo menciona algunos de los problemas actuales en México y algunas opciones de solución para los mismos.

Use of Initial Endotracheal Versus Intravenous Epinephrine During Neonatal Cardiopulmonary Resuscitation in the Delivery Room: Review of a National Database.

OBJECTIVE: To assess whether initial epinephrine administration by endotracheal tube (ET) in newly born infants receiving chest compressions and epinephrine in the delivery room (DR) is associated with lower rates of return of spontaneous circulation (ROSC) than newborns receiving initial intravenous (IV) epinephrine. STUDY DESIGN: We conducted a retrospective review of neonates receiving chest compressions and epinephrine in the DR from the AHA Get With The Guidelines-Resuscitation registry from October 2013 through July 2020. Neonates were classified according to initial route of epinephrine (ET vs IV). The primary outcome of interest was ROSC in the DR. RESULTS: In total, 408 infants met inclusion criteria; of these, 281 (68.9%) received initial ET epinephrine and 127 (31.1%) received initial IV epinephrine. The initial ET epinephrine group included those infants who also received subsequent IV epinephrine when ET epinephrine failed to achieve ROSC. Comparing initial ET with initial IV epinephrine, ROSC was achieved in 70.1% vs 58.3% (adjusted risk difference 10.02; 95% CI 0.05-19.99). ROSC was achieved in 58.3% with IV epinephrine alone, and 47.0% with ET epinephrine alone, with 40.0% receiving subsequent IV epinephrine. CONCLUSIONS: This study suggests that initial use of ET epinephrine is reasonable during DR resuscitation, as there were greater rates of ROSC compared with initial IV epinephrine administration. However, administration of IV epinephrine should not be delayed in those infants not responding to initial ET epinephrine, as almost one-half of infants who received initial ET epinephrine subsequently received IV epinephrine before achieving ROSC.

Coexistence of a fluid responsive state and venous congestion signals in critically ill patients: a multicenter observational proof-of-concept study.

BACKGROUND: Current recommendations support guiding fluid resuscitation through the assessment of fluid responsiveness. Recently, the concept of fluid tolerance and the prevention of venous congestion (VC) have emerged as relevant aspects to be considered to avoid potentially deleterious side effects of fluid resuscitation. However, there is paucity of data on the relationship of fluid responsiveness and VC. This study aims to compare the prevalence of venous congestion in fluid responsive and fluid unresponsive critically ill patients after intensive care (ICU) admission. METHODS: Multicenter, prospective cross-sectional observational study conducted in three medical-surgical ICUs in Chile. Consecutive mechanically ventilated patients that required vasopressors and admitted < 24 h to ICU were included between November 2022 and June 2023. Patients were assessed simultaneously for fluid responsiveness and VC at a single timepoint. Fluid responsiveness status, VC signals such as central venous pressure, estimation of left ventricular filling pressures, lung, and abdominal ultrasound congestion indexes and relevant clinical data were collected. RESULTS: Ninety patients were included. Median age was 63 [45-71] years old, and median SOFA score was 9 [7-11]. Thirty-eight percent of the patients were fluid responsive (FR+), while 62% were fluid unresponsive (FR-). The most prevalent diagnosis was sepsis (41%) followed by respiratory failure (22%). The prevalence of at least one VC signal was not significantly different between FR+ and FR- groups (53% vs. 57%, p = 0.69), as well as the proportion of patients with 2 or 3 VC signals (15% vs. 21%, p = 0.4). We found no association between fluid balance, CRT status, or diagnostic group and the presence of VC signals. CONCLUSIONS: Venous congestion signals were prevalent in both fluid responsive and unresponsive critically ill patients. The presence of venous congestion was not associated with fluid balance or diagnostic group. Further studies should assess the clinical relevance of these results and their potential impact on resuscitation and monitoring practices.

Lactate and lactate clearance as predictors of one-year survival in extracorporeal cardiopulmonary resuscitation - An international, multicentre cohort study.

AIM: Extracorporeal cardiopulmonary resuscitation (ECPR) can be considered in selected patients with refractory cardiac arrest. Given the risk of patient futility and high resource utilisation, identifying ECPR candidates, who would benefit from this therapy, is crucial. Previous ECPR studies investigating lactate as a potential prognostic marker have been small and inconclusive. In this study, it was hypothesised that the lactate level (immediately prior to initiation of ECPR) and lactate clearance (within 24 hours after ECPR initiation) are predictors of one-year survival in a large, multicentre study cohort of ECPR patients. METHODS: Adult patients with refractory cardiac arrest at three German and four Danish tertiary cardiac care centres between 2011 and 2021 were included. Pre-ECPR lactate and 24-hour lactate clearance were divided into three equally sized tertiles. Multivariable logistic regression analyses and Kaplan-Meier analyses were used to analyse survival outcomes. RESULTS: 297 adult patients with refractory cardiac arrest were included in this study, of which 65 (22%) survived within one year. The pre-ECPR lactate level and 24-hour lactate clearance were level-dependently associated with one-year survival: OR 5.40 [95% CI 2.30-13.60] for lowest versus highest pre-ECPR lactate level and OR 0.25 [95% CI 0.09-0.68] for lowest versus highest 24-hour lactate clearance. Results were confirmed in Kaplan-Meier analyses (each p log rank < 0.001) and subgroup analyses. CONCLUSION: Pre-ECPR lactate levels and 24 hour-lactate clearance after ECPR initiation in patients with refractory cardiac arrest were level-dependently associated with one-year survival. Lactate is an easily accessible and quickly available point-of-care measurement which might be considered as an early prognostic marker when considering initiation or continuation of ECPR treatment.

Assessment of preparedness and proficiency in basic and advanced life support among nursing professionals: a cross-sectional study.

Background: Cardiac diseases are among the leading causes of death worldwide, including sudden cardiac arrest in particular. Nursing professionals are often the first to encounter these scenarios in various settings. Adequate preparation and competent knowledge among nurses significantly impact survival rates positively. Aim: To describe the state of knowledge about Basic and Advanced Life Support guidelines among Ecuadorian nursing professionals. Methodology: A nationwide, descriptive, cross-sectional study was conducted from February to April 2023 among Ecuadorian nursing professionals. Participants were invited through official social media groups such as WhatsApp and Facebook. The study utilized a self-administered online questionnaire to evaluate theoretical knowledge of Basic Life Support (BLS) and Advanced Life Support (ALS). Knowledge scores were assigned based on the number of correct answers on the tests. T-tests and one-way ANOVA were used to examine relationships between knowledge scores and demographic and academic training variables. Results: A total of 217 nursing professionals participated in the study. The majority of the participants were female (77.4%) and held a university degree (79.9%). Among them, only 44.7% claimed to have obtained a BLS training certificate at least once, and 19.4% had ALS certification. The overall BLS knowledge score (4.8/10 ± 1.8 points) was higher than the ALS score (4.3/10 ± 1.8 points). Participants who had obtained BLS certification and those who used evidence-based summaries as a source of extracurricular training achieved higher BLS and ALS knowledge scores. Conclusion: Ecuadorian nursing professionals in this study exhibited a significant deficiency in theoretical knowledge of BLS and ALS. Formal training and preparation positively impact life support knowledge. Support and inclusion of Ecuadorian nurses in training and academic preparation programs beginning at the undergraduate level are essential for promoting life support knowledge and improving outcomes.

Is REBOA the Last Card to Control a Massive Gastrointestinal Bleeding?

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potential tool for the management of massive gastrointestinal bleeding (MGB). This study aims to describe the experience of the use of REBOA as adjunctive therapy in patients with MGB and to evaluate its effectiveness. METHODS: Serial cases of patients with hemorrhagic shock secondary to MGB in whom REBOA was placed were collected. Patient demographics, bleeding severity, etiology, management, and clinical outcomes were recorded. RESULTS: Between 2017 and 2020, five cases were analyzed. All patients had a severe gastrointestinal bleeding (Glasgow Blatchford Bleeding Score range 12-17; Clinical Rockal Score range 5-9). The etiologies of MGB were perforated gastric or duodenal ulcers, esophageal varices, and vascular lesions. Systolic blood pressure increased after REBOA placement and total occlusion time was 25-60 min. REBOA provided temporary hemorrhage control in all cases and allowed additional hemostatic maneuvers to be performed. Three patients survived more than 24 h. All patients died in index hospitalization. The main cause of death was related to hemorrhagic shock. CONCLUSIONS: Endovascular aortic occlusion can work as a bridge to further resuscitation and attempts at hemostasis in patients with MGB. REBOA provides hemodynamic support and may be used simultaneously with other hemostatic maneuvers, facilitating definitive hemorrhage control.

Assessing the Proficiency in Basic and Advanced Life Support Among Physicians in Ecuador: A Cross-Sectional Study.

Purpose: Cardiorespiratory arrest's unpredictability poses a global health challenge, with gaps in physicians' life support knowledge potentially leading to poor patient outcomes, a factor yet unstudied among Ecuadorian physicians. This study aims to elucidate the state of physicians' theoretical knowledge in Ecuador based on Basic Life Support (BLS) and Advanced Life Support (ALS) guidelines. Patients and methods: A national cross-sectional online 35-questions survey was conducted between February and March 2023 using a self-administered, expert-validated questionnaire. Participants' responses were obtained through official social media groups (WhatsApp and Facebook). The survey evaluated the theoretical knowledge of BLS and ALS, with scores based on the number of correct answers out of a maximum of 10.0 points. For descriptive analysis, frequencies, percentages, means, and standard deviations (SD) were used. The T-test and one-way ANOVA were utilized to analyze the associations between knowledge levels and demographic and academic training variables of Ecuadorian doctors. Values of p < 0.05 were considered statistically significant for all analyses. Results: The survey garnered responses from 385 physicians, with a majority being female (56.6%) and possessing less than 3 years of work experience (75.1%). Of these, 71.7% and 51.9% held BLS and ALS certifications, respectively. Knowledge scores for BLS (5.8/10 ± 1.6) surpassed those for ALS (4.7/10 ± 1.8) (p < 0.001). Physicians with less than 3 years of work experience exhibited higher knowledge scores in both BLS and ALS tests (p < 0.05). Conclusion: This study revealed a notable deficiency in the theoretical knowledge of BLS and ALS among surveyed Ecuadorian physicians. Factors such as prior certification and years of work experience appeared to influence knowledge levels. Continual training and updates in life support protocols at universities and healthcare institutions are key to enhancing physicians' skills and patient outcomes.

The association between prolonged capillary refill time and microcirculation changes in children with sepsis.

BACKGROUNDS: In children with sepsis, circulatory shock and multi-organ failure remain major contributors to mortality. Prolonged capillary refill time (PCRT) is a clinical tool associated with disease severity and tissue hypoperfusion. Microcirculation assessment with videomicroscopy represents a promising candidate for assessing and improving hemodynamic management strategies in children with sepsis. Particularly when there is loss of coherence between the macro and microcirculation (hemodynamic incoherence). We sought to evaluate the association between PCRT and microcirculation changes in sepsis. METHODS: This was a prospective cohort study in children hospitalized with sepsis. Microcirculation was measured using sublingual video microscopy (capillary density and flow and perfused boundary region [PBR]-a parameter inversely proportional to vascular endothelial glycocalyx thickness), phalangeal tissue perfusion, and endothelial activation and glycocalyx injury biomarkers. The primary outcome was the association between PCRT and microcirculation changes. RESULTS: A total of 132 children with sepsis were included, with a median age of two years (IQR 0.6-12.2). PCRT was associated with increased glycocalyx degradation (PBR 2.21 vs. 2.08 microns; aOR 2.65, 95% CI 1.09-6.34; p = 0.02) and fewer 4-6 micron capillaries recruited (p = 0.03), with no changes in the percentage of capillary blood volume (p = 0.13). Patients with hemodynamic incoherence had more PBR abnormalities (78.4% vs. 60.8%; aOR 2.58, 95% CI 1.06-6.29; p = 0.03) and the persistence of these abnormalities after six hours was associated with higher mortality (16.5% vs. 6.1%; p < 0.01). Children with an elevated arterio-venous CO2 difference (DCO2) had an abnormal PBR (aOR 1.13, 95% CI 1.01-1.26; p = 0.03) and a lower density of small capillaries (p < 0.05). Prolonged capillary refill time predicted an abnormal PBR (AUROC 0.81, 95% CI 0.64-0.98; p = 0.03) and relative percentage of blood in the capillaries (AUROC 0.82, 95% CI 0.58-1.00; p = 0.03) on admission. A normal CRT at 24 h predicted a shorter hospital stay (aOR 0.96, 95% CI 0.94-0.99; p < 0.05). CONCLUSIONS: We found an association between PCRT and microcirculation changes in children with sepsis. These patients had fewer small capillaries recruited and more endothelial glycocalyx degradation. This leads to nonperfused capillaries, affecting oxygen delivery to the tissues. These disorders were associated with hemodynamic incoherence and worse clinical outcomes when the CRT continued to be abnormal 24 h after admission.

Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients.

Interdisciplinary training program for pediatric cardiorespiratory arrest using rapid cycle deliberate practice: A descriptive cross-sectional study

ABSTRACT BACKGROUND: cardiorespiratory arrest (CRA) is a severe public health concern, and clinical simulation has proven to be a beneficial educational strategy for training on this topic. OBJECTIVE: To describe the implementation of a program for pediatric cardiac arrest care using rapid-cycle deliberate practice (RCDP), the quality of the technique employed, and participants' opinions on the methodology. DESIGN AND SETTING: This descriptive cross-sectional study of pre- and post-performance training in cardiopul monary resuscitation (CPR) techniques and reaction evaluation was conducted in a hospital in São Paulo. METHODS: Multidisciplinary groups performed pediatric resuscitation in a simulated scenario with RCDP mediated by a facilitator. The study sample included professionals working in patient care. During the simulation, the participants were evaluated for their compliance with the CRA care algorithm. Further, their execution of chest compressions was assessed pre- and post-intervention. RESULTS: In total, 302 professionals were trained in this study. The overall quality of CPR measured pre-intervention was inadequate, and only 26% had adequate technique proficiency, whereas it was 91% (P < 0.01) post-intervention. Of the participants, 95.7% responded to the final evaluation and provided positive comments on the method and their satisfaction with the novel simulation. Of these, 88% considered that repetition of the technique used was more effective than traditional simulation. CONCLUSIONS: The RCDP is effective for training multidisciplinary teams in pediatric CPR, with an emphasis on the quality of chest compressions. However, further studies are necessary to explore whether this trend translates to differential performances in practical settings.

Influence of blood hemodynamics on the treatment outcomes of limited fluid resuscitation in emergency patients with traumatic hemorrhagic shock.

OBJECTIVES: Traumatic hemorrhagic shock is a major death-related factor contributing to mortality in emergencies and can be effectively handled by the Limited Fluid Resuscitation (LFR) method. In the current investigation, the authors analyzed the influence of different administrating blood pressure on the treatment outcomes of LFR. METHODS: 276 participants were enrolled in the current study retrospectively from January 2016 to December 2021 and were divided into three groups based on the administrating blood pressure of LFR. The difference among the three groups regarding serum levels of cytokines as well as blood hemodynamics parameters was analyzed. RESULTS: The results showed after the T2 stage treatment, cytokine levels in the three groups were all significantly influenced by different LFR strategies with medium MAP showing the strongest effects on the expression of all cytokine genes. Moreover, the MAP value was in positive correlation with IL-6, IL-10, and TNF-α levels, but showed no clear relation with IL-4 level in all three groups. Regarding the effects on hemodynamics parameters, the levels of CVP, CO, and CI were slightly increased by the different LFR administrating strategies, and the effect of medium and high MAP was statistically stronger than that of low MAP. CONCLUSION: The present results showed that LFR would influence serum inflammatory levels by improving blood hemodynamics parameters. Medium MAP showed the strongest improving effects with the least side effects, which can be employed as the optimal administrating strategy for LFR in the future.
