ABSTRACT

Objetivo: identificar características clínicas das paradas cardiopulmonares e reanimações cardiopulmonares ocorridas em ambiente intra-hospitalar. Método: estudo quantitativo, prospectivo e observacional, a partir de informações de prontuários de pacientes submetidos a manobras de reanimação devido à parada cardiopulmonar entre janeiro e dezembro de 2021. Utilizou-se um instrumento baseado nas variáveis do modelo de registro Utstein. Resultados: em 12 meses foram registradas 37 paradas cardiopulmonares. A maioria ocorreu na unidade de terapia intensiva respiratória, com causa clínica mais prevalente hipóxia. 65% dos pacientes foram intubados no atendimento e 57% apresentaram ritmo atividade elétrica sem pulso. A duração da reanimação variou entre menos de cinco a mais de 20 minutos. Como desfecho imediato, 57% sobreviveram. Conclusão: dentre os registros analisados, a maior ocorrência de paradas cardiopulmonares foi na unidade de terapia intensiva respiratória, relacionada à Covid-19. Foram encontrados registros incompletos e ausência de padronização nas condutas.


Objective: identify the clinical characteristics of cardiopulmonary arrests and cardiopulmonary resuscitations in the in-hospital environment. Method: this is a quantitative, prospective and observational study based on information from the medical records of patients who underwent resuscitation maneuvers due to cardiopulmonary arrest between January and December 2021. An instrument based on the variables of the Utstein registration protocol was used. Results: thirty-seven cardiopulmonary arrests were recorded in 12 months. The majority occurred in a respiratory intensive care unit, with hypoxia being the most prevalent clinical cause. Sixty-five percent of the patients were intubated and 57% had pulseless electrical activity. The duration of resuscitation ranged from less than five to more than 20 min. As for the immediate outcome, 57% survived. Conclusion: among the records analyzed, the highest occurrence of cardiopulmonary arrests was in respiratory intensive care units, and they were related to Covid-19. Moreover, incomplete records and a lack of standardization in cardiopulmonary resuscitation procedures were found.

ABSTRACT

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.

ABSTRACT

Resumen Antecedentes: Los niños con cardiopatías congénitas experimentan paro cardiorrespiratorio (PCR) con mayor frecuencia que la población pediátrica general. Se desconoce la epidemiología exacta del PCR en nuestro medio, al igual que el riesgo de mortalidad y los factores que influyen en la evolución neurológica. Objetivo: Describir la epidemiología y los resultados asociados con la reanimación cardiopulmonar pediátrica en una unidad de recuperación cardiovascular. El criterio de valoración primario fue la supervivencia al momento del alta hospitalaria; los secundarios fueron el retorno de la circulación espontánea, la supervivencia a las 24 horas y la condición neurológica en el largo plazo. Método: Estudio de cohorte longitudinal, descriptivo, prospectivo, en menores de 18 años que requirieron reanimación cardiopulmonar entre 2016 y 2019. Se analizaron las variables demográficas y las características del paro cardiorrespiratorio y de la reanimación, así como su resultado. Se realizaron análisis de una y múltiples variables para comparar a los pacientes sobrevivientes con los fallecidos. Resultados: De los 1,842 pacientes internados, el 4.1% experimentó PCR. Se analizaron 50 pacientes con expedientes completos. Se logró el retorno de la circulación espontánea en el 78% (39), con una supervivencia alta del 46%. La reanimación > 6 min y el uso de fármacos vasoactivos fueron factores predictivos de mortalidad; se realizó el seguimiento de 16/23 pacientes, 10 de ellos con desarrollo normal para la edad luego de seis meses, seis tenían trastorno generalizado del desarrollo. Conclusiones: El 4.1% de los pacientes presentó un PCR, con una tasa de 3.4 PCR por 1,000 días-paciente. La supervivencia al egreso hospitalario (n = 50) fue del 46%. La reanimación > 6 min y la utilización de fármacos vasoactivos fueron factores predictivos independientes de mortalidad. Luego de seis meses, el 63% tenía desarrollo neurológico normal para la edad.


Abstract Background: Children with congenital heart disease present a higher frequency of cardiorespiratory arrest (CRA) than the general pediatric population. The epidemiology of CRA is not exactly known in our setting, nor are the mortality risk or the neurological evolution factors. Objective: To describe the epidemiology and outcomes associated with pediatric cardiopulmonary resuscitation in a cardiovascular recovery unit. The primary endpoint was the survival to discharge and the secondary endpoints were the return to spontaneous circulation, the survival at 24 hours and the remote neurological condition. Methods: Descriptive, prospective, longitudinal cohort study in children under 18 years of age who required cardiopulmonary resuscitation between 2016 and 2019. Demographic variables, characteristics of cardiopulmonary arrest, resuscitation and outcome were analyzed. An uni- and multivariate analysis was performed comparing survivors and deceased. Results: Out of 1,842 hospitalized patients, 4.1% presented CRA. Fifty patients with complete records were analyzed. Seventy-eight percent (39) returned to spontaneous circulation with a high survival rate of 46%. Resuscitation > 6 min and the use of vasoactive drugs were predictors of mortality; 16/23 patients were followed up, 10 of them with normal development for age at 6 months, six had pervasive developmental disorder. Conclusions: 4.1% of patients presented CRA, with a rate of 3.4 CRA per 1,000 patient-days. Survival at hospital discharge (n = 50) was 46%. Resuscitation > 6 min and the use of vasoactive drugs were independent predictors of mortality. At six months, 63% had normal neurological development for age.

ABSTRACT

Objective:To screen the independent influencing factors of restoration of spontaneous circulation (ROSC) in patients after cardiopulmonary resuscitation (CPR) and establish a predictive model, and explore its clinical value.Methods:A retrospective case control study was conducted. The clinical data of cardiac arrest patients admitted to the emergency department of Tangdu Hospital of Air Force Military Medical University and received CPR from January to July 2023 were analyzed, including general information, blood biochemical indicators, main cause of cardiac arrest, whether it was defibrillation rhythm, duration from admission to CPR, and whether ROSC was achieved. The clinical data between the patients whether achieved ROSC or not were compared. The binary multivariate Logistic regression analysis was used to screen the independent influencing factors of ROSC in in-hospital CPR patients. According to the above influencing factors, the ROSC prediction model was established, and the receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of the model for ROSC.Results:A total of 235 patients who received CPR in the emergency department were enrolled, including 153 cases (65.11%) of in-hospital CPR and 82 cases (34.89%) of out-of-hospital CPR. The ROSC ratio was 30.21% (71/235). Among all patients, the majority were aged 61-80 years [40.43% (95/235)], and cardiogenic disease was the main cause of cardiac arrest [32.77% (77/235)]. Among 153 patients with in-hospital CPR, 89 were non-ROSC and 64 were ROSC with ROSC rate of 41.83%. Compared with the non-ROSC group, the patients in the ROSC group had lower blood lactic acid (Lac), N-terminal pro-brain natriuretic peptide (NT-proBNP), Lac/albumin (Alb) ratio (LAR), and ratio of non-defibrillation rhythm [Lac (mmol/L): 5.50 (2.33, 9.65) vs. 7.10 (3.50, 13.35), NT-proBNP (μg/L): 0.87 (0.20, 8.68) vs. 3.00 (0.58, 20.17), LAR: 0.14 (0.07, 0.29) vs. 0.19 (0.10, 0.43), non-defibrillation rhythm ratio: 68.75% (44/64) vs. 93.26% (83/89)], higher actual base excess (ABE) and Alb [ABE (mmol/L): -3.95 (-12.75, 0.23) vs. -7.50 (-13.50, -3.35), Alb (g/L): 38.13±7.03 vs. 34.09±7.81], and shorter duration from admission to CPR [hours: 3.25 (1.00, 14.00) vs. 8.00 (2.00, 27.50)], the differences were statistically significant (all P < 0.05). Binary multivariate Logistic regression analysis showed that LAR [odds ratio ( OR) = 0.037, 95% confidence interval (95% CI) was 0.005-0.287], non-defibrillation rhythm ( OR = 0.145, 95% CI was 0.049-0.426), and duration from admission to CPR ( OR = 0.984, 95% CI was 0.972-0.997) were independent influencing factors for ROSC in hospitalized CPR patients (all P < 0.05). Based on the above influencing factors, a ROSC prediction model was constructed through regression analysis results. The ROC curve analysis showed that the area under the ROC curve (AUC) for predicting ROSC in in-hospital CPR patients was 0.757 (95% CI was 0.680-0.834), Yoden index was 0.429, sensitivity was 76.6%, and specificity was 66.3%. Conclusions:LAR, non-defibrillation rhythm and duration from admission to CPR were independent influencing factors for ROSC in patients with in-hospital CPR. The ROSC prediction model established based on the above influencing factors has a good predictive value for ROSC of CPR patients in hospital, and can guide clinicians to evaluate the prognosis of patients through relevant indicators as early as possible.

ABSTRACT

Objective:To establish the rat cardiac arrest model in high-altitude hypobaric hypoxia environment, and to explore the effect of the treatment time in the hypobaric oxygen chamber on the reproduction of high-altitude rat cardiac arrest model.Methods:SPF grade healthy male Sprague-Dawley (SD) rats were used as observation subjects. The experiment was conducted in two different altitude areas. The rats from the Plateau Branch of Institute of Cardiopulmonary and Cerebral Resuscitation of Sun Yat-sen University (Xining, Qinghai) were weighed and numbered, and they were placed in a hypobaric oxygen chamber (simulated altitude of 3 000 meters, speed of ascent and descent of 15 m/min, temperature of 20 ℃, cabin pressure of 69.5 kPa, cabin oxygen pressure of 14.5 kPa). After 30 days of feeding, the rats were obtained according to random number table method, and the cardiac arrest model was established by asphyxia method as the 30-day hypobaric hypoxia group. After 60 days of feeding, rats were randomly selected again, and the cardiac arrest model was established as the 60-day hypobaric hypoxia group. Thirty rats were randomly selected from the Institute of Cardiopulmonary Cerebral Resuscitation at Sun Yat-sen University (Guangzhou, Guangdong) by the same method, and the cardiac arrest model was established as the plain control group. The differences in the body weight of rat modeling precursors and the induction time of asphyxia during the modeling process among different groups were compared.Results:Finally, cardiac arrest model was established in 16 rats in the 30-day hypobaric hypoxia group and in 22 rats in the 60-day hypobaric hypoxia group. There was no significant difference in the body weight of rats before modeling among the plain control group, 30-day hypobaric hypoxia group and 60-day hypobaric hypoxia group [g: 429.00 (389.25, 440.75), 440.00 (415.50, 486.25), 440.00 (400.00, 452.50), all P > 0.05]. The asphyxia induction time of rats in the 60-day hypobaric hypoxia group was significantly longer than that in the 30-day hypobaric hypoxia group (s: 294.59±75.39 vs. 234.31±93.86, P < 0.01), even about 1.4 times of the plain control group (s: 294.59±75.39 vs. 208.73±30.88, P < 0.01). There was no significant difference in the asphyxia induction time between the 30-day hypobaric hypoxia group and the plain control group ( P > 0.05). Conclusion:Rats treated in a hypobaric oxygen chamber for 60 days are more suitable for the preparation of high-altitude cardiac arrest model, and are also consistent with the oxygen reserve and hypoxia tolerance of high-altitude rats.

ABSTRACT

The main clinical research advances of critical care in 2023 includes: new trials of Chinese herbal medicine, hydroxocobalamin (vitamin B12), methylene blue as well glucocorticoids have shown the potential to improve outcomes of patients with sepsis and septic shock; international committees launched new global definition and managing recommendations for acute respiratory distress syndrome (ARDS). Besides, a cluster of new evidences has emerged in many aspects as following: fluid control strategy in sepsis (restrictive/liberative), antibiotic infusion strategy (continuous/intermittent), oxygen-saturation targets for mechanical ventilation (conservative/liberative), blood pressure targets after resuscitation from out-of-hospital cardiac arrest (hypotension/hypertension), blood pressure targets after successful stroke thrombectomy (intensive/conventional), and nutritional support strategies (low protein-calories/conventional protein-calories, fasting/persistent feeding before extubation). Thus, given above progress, carrying out high -quality domestic multi-center clinical registration researches, constructing shareable standardized databases, as well raising public awareness of sepsis, should be the essential steps to improve our level of intensive care medicine.

ABSTRACT

Objective:To investigate the factors that influence the return of spontaneous circulation (ROSC) in elderly patients suffering from out-of-hospital cardiac arrest (OHCA).Methods:A retrospective study was used to collect the clinical data of OHCA patients admitted to the emergency center of Zhengzhou People's Hospital from July 2016 to July 2019 based on the pre-hospital emergency database of Utstein model. Patients' gender, age, cardiac arrest (CA) etiology, presence or absence of bystander cardiopulmonary resuscitation (CPR), emergency response time, initial cardiac rhythm, ventilation method, use of epinephrine, defibrillation and ROSC were included. The patients were divided into elderly and young groups according to whether age ≥ 60 years old, and the differences in various indicators between the two groups were compared. Univariate Logistic regression analysis was used to analyze the relationship between emergency response time and ROSC in elderly patients and multivariate Logistic regression analysis was used to identify factors influencing ROSC in elderly patients.Results:A total of 3?429 adult OHCA patients were enrolled in this study, including 2?105 elderly patients (61.39%), and 1?324 young and middle-aged patients (38.61%). Compared to the young group, the proportion of females, non-cardiac causes and asystole as the initial rhythm was higher in the elderly group, the emergency response time was shorter, the rate of defibrillation and tracheal intubation, and the success rate of ROSC were lower (all P < 0.05). Among them, the proportion of cardiac arrest as the initial rhythm in elderly male patients was significantly higher than that of young male patients ( P < 0.05); the proportion of non-cardiac causes in elderly female patients was significantly higher than that of young female patients, and the proportion of defibrillation was significantly lower than that of young female patients (all P < 0.05). Multivariate Logistic regression analysis showed that cardiac arrest as the initial rhythm was strongly associated with ROSC in elderly male patients [odds ratio ( OR) = 0.126, 95% confidence interval (95% CI) was 0.045-0.352, P < 0.05]. Univariate Logistic regression analysis of the relationship between emergency response time and ROSC in elderly patients showed that although there was no significant difference in the ROSC success rate among elderly patients with various emergency response times, an emergency response time within 10 minutes was beneficial for ROSC in elderly patients. Conclusion:The success rate of ROSC is very low in elderly OHCA patients aged ≥60 years. Although the CPR-related indicators of elderly patients are significantly different from those of young patients, there are gender differences. The association between the elderly male patients and cardiac arrest as the initial rhythm is stronger, while OHCA caused by non-cardiac diseases is more common and defibrillable rhythm is less common in elderly female patients. It may be more beneficial for elderly patients to shorten the emergency response time and increase bystander CPR.

ABSTRACT

Cardiac arrest (CA) is a serious cardiac event, which has a high incidence and low survival rate at home and abroad. In order to predict the risk of CA in advance, a large number of studies have been conducted by relevant researchers. This paper mainly summarizes the characteristics and research status of the existing analysis and prediction of CA from three aspects: the risk prediction factors of CA, the evaluation index of risk prediction of CA and the early warning scoring system of CA. We hope it can help medical staff to understand the current progress in this field, and provide new ways and methods for predicting the risk of CA.

ABSTRACT

Objective:The predictive model of cardiac arrest in the emergency room was constructed and validated based on Logistic regression.Methods:This study was a retrospective cohort study. Patients admitted to the emergency room of the First Affiliated Hospital of Xinjiang Medical University from January 2020 to July 2021 were included. The general information, vital signs, clinical symptoms, and laboratory examination results of the patients were collected, and the outcome was cardiac arrest within 24 hours. The patients were randomly divided into modeling and validation group at a ratio of 7:3. LASSO regression and multivariable logistic regression were used to select predictive factors and construct a prediction model for cardiac arrest in the emergency room. The value of the prediction model was evaluated using the area under the receiver operator characteristic curve (AUC), calibration curve, and decision curve analysis (DCA).Results:A total of 784 emergency room patients were included in the study, 384 patients occurred cardiac arrest. The 10 variables were ultimately selected to construct a risk prediction model for cardiac arrest: Logit( P)= -4.503+2.159×modified early warning score (MEWS score)+2.095×chest pain+1.670×abdominal pain+ 2.021×hematemesis+2.015×cold extremities+5.521×endotracheal intubation+0.388×venous blood lactate-0.100×albumin+0.768×K ++0.001×D-dimer. The AUC of the model group was 0.984 (95% CI: 0.976-0.993) and that of the validation group was 0.972 (95% CI: 0.951-0.993). This prediction model demonstrates good calibration, discrimination, and clinical applicability. Conclusions:Based on the MEWS score, chest pain, abdominal pain, hematemesis, cold extremities, tracheal intubation, venous blood lactate, albumin, K +, and D-dimer, a predictive model for cardiac arrest in the in-hospital emergency room was constructed to predict the probability of cardiac arrest in emergency room patients and adjust the treatment strategy in time.

ABSTRACT

Objective:To analyze the causes of out-of-hospital cardiac arrest (OHCA) and the differences in outcomes of pre-hospital first-aid measures and cardiopulmonary resuscitation for different etiologies, improved the success rate of rescue.Methods:A retrospective study was conducted on OHCA patients admitted to Beijing Emergency Medical Centre from January to December 2021. The pre-hospital emergency medical records and rescue results within medical institutions were collected. Compared the basic situation between patients with cardiogenic and non-cardiogenic cardiac arrest, the differences of rescue measures and CPR outcomes between the groups were compared by non-parametric test and χ 2 test. Results:A total of 7 517 patients were included in this study. Cardiogenic arrest patients were older, more underlying diseases (84.2%), and cardiac arrest mainly occurred at home. The cause of non-cardiogenic arrest included disease (85.1%), trauma (2.9%), suicide (5.0%), traffic accidents (1.7%), poisoning (1.1%), and so on. In terms of first-aid measures, after the emergency doctor arrived at the scene, the proportion of first-aid measures used for cardiogenic patients was high (22.3%), and the first aid measures include cardiopulmonary resuscitation, tracheal intubation, defibrillation, oxygen inhalation, injection of adrenaline and use of other drugs. All the proportions of first-aid measures for cardiogenic patients were significantly higher than non-cardiogenic patients (all P<0.001). In terms of clinical outcomes, there were no statistical differences in return of spontaneous circulation ( P=0.072) and 24-hour survival ( P=0.093) between cardiogenic and non-cardiogenic patients. Conclusions:Cardiogenic cardiac arrest was the main cause of OHCA. Cardiogenic arrest patients were more underlying diseases, and older in age, the main clinical feature was onset at home. The comprehensive treatment measures for pre-hospital first-aid cardiac arrest should continue to be strengthened to improve the success rate of rescue for OHCA.

ABSTRACT

Objective:To analyze and discuss the characteristics of cardiopulmonary and cerebral resuscitation (CPCR) in patients after out-of-hospital cardiac arrest (OHCA).Methods:The data of OHCA patients admitted to the directly-managed branch of the Wuxi Emergency Medical Center, covering the period from December 26, 2016, at 7:45 to August 26, 2022, at 7:45. The analysis included the first electrocardiogram (ECG), clinical characteristics, pre-hospital emergency measures, and follow-up conditions in the hospital. Based on the Glasgow-Pittsburgh cerebral function grading at discharge, patients were divided into a CPCR group (grades 1-2) and a non-CPCR group (grades 3-5). The study compared the basic conditions, resuscitation times, and vital signs after resuscitation between the two groups to evaluate the factors affecting CPCR.Results:A total of 6 040 OHCA cases were treated, 3 002 cases received pre-hospital resuscitation. The initial ECG indicated a shockable rhythm in 185 cases, with a shockable rhythm rate of 6.16%. There were 293 pre-hospital survivors, with a pre-hospital survival rate of 9.76%. 170 cases survived to be discharged, with a discharge survival rate of 5.66%. Ultimately, 44 cases achieved CPCR, accounting for 25.88% of the cases that survived to discharge. There were statistically significant differences in terms of first-witness treatment, defibrillable rhythm ratio, defibrillation, response to pain stimulation after return of spontaneous circulation (ROSC), spontaneous breathing, light reflex, pulse oxygenation, and blood pressure between the CPCR and non-CPCR groups (all P<0.05). The CPCR group showed significantly higher proportions than the non-CPCR group in the defibrillatable rhythm (75.00% vs. 10.44%), undergoing defibrillation (70.46% vs. 9.24%), having spontaneous breathing after ROSC (86.36% vs. 17.27%), and having oxygen saturation >92% with systolic blood pressure >90 mmHg (86.36% vs. 39.76%).There were statistically significant differences between the CPCR and non-CPCR groups in the time from cardiac arrest (CA) to doctor reception, CA to first defibrillation, CA to ROSC, and CA to discharge or in-hospital death (all P<0.05). Conclusions:The patients with successful pre-hospital resuscitation and finally cerebral resuscitation were characterized by short times from OHCA to first medical contact (FMC) and from FMC to ROSC, appropriate pre-hospital vital sign management accompanied by partial neurological recovery, and comprehensive in-hospital neurological prognosis assessment.

ABSTRACT

Objective:To analyze the clinical characteristics of patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR), and to explore the risk factors leading to poor prognosis.Methods:The clinical data of 95 patients with ECPR admitted to the First Affiliated Hospital of Zhengzhou University from January 2020 to May 2023 were retrospectively analyzed. According to the survival status at the time of discharge, the patients were divided into the survival group and death group. The difference of clinical data between the two groups was compared to explore the risk factors related to death and poor prognosis. Risk factors associated with death were identified by Binary Logistic regression analysis. Results:A total of 95 patients with ECPR were included in this study, 62 (65.3%) died and 33 (34.7%) survived at discharge. Patients in the death group had longer low blood flow time [40 (30, 52.5) min vs. 30 (24.5, 40) min ] and total cardiac arrest time[40 (30, 52.5) min vs. 30(24.5, 40) min], shorter total hospital stay [3 (2, 7.25) d vs. 19 (13.5, 31) d] and extracorporeal membrane oxygenation (ECMO) assisted time [26.5 (17, 50) h vs. 62 (44, 80.5) h], and more IHCA patients (56.5% vs. 33.3%) and less had spontaneous rhythm recovery before ECMO (37.1% vs. 84.8%). Initial lactate value [(14.008 ± 5.188) mmol/L vs.(11.23 ± 4.718) mmol/L], APACHEⅡ score [(30.10 ± 7.45) vs. (25.88 ± 7.68)] and SOFA score [12 (10.75, 16) vs. 10 (9.5, 13)] were higher ( P< 0.05). Conclusions:No spontaneous rhythm recovery before ECMO, high initial lactic acid and high SOFA score are independent risk factors for poor prognosis in ECPR patients.

ABSTRACT

Objective:To establish the pig model of cardiac arrest and resuscitation, and then investigate the protective role of sivelestat (SV) on the heart after resuscitation and its relation with β-catenin signaling pathway.Methods:Twenty-five healthy male white pigs were purchased. The animals were randomly divided into the Sham group ( n=6), cardiopulmonary resuscitation group (CPR, n=10), and CPR+SV group ( n=9). The experimental animal model was established by 9 min of cardiac arrest induced by the method of ventricular fibrillation and then 6 min of CPR in the CPR and CPR+SV groups. At 5 min after successful resuscitation, a dose of 10 mg/kg of SV was infused in a duration of 1h via the femoral vein with a micro-infusion pump in the CPR+SV group. Myocardial function evaluated by the values of stroke volume (SV) and global ejection fraction (GEF) was measured by PiCCO at baseline, and at 0.5, 1, 2, 4 h after resuscitation. The serum concentrations of cardiac injury biomarkers including cardiac troponin I (cTnI) and creatine kinase isoenzymes (CK-MB) were measured by ELISA using blood samples drawn from the femoral vein at baseline, and at 1, 2, 4, and 24 h after resuscitation. The animals were euthanized at 24 h after resuscitation, and then cardiac tissue samples were harvested to measure the protein expression levels of β-catenin, Cyclin D1, c-Myc, cleaved caspase-9, and cleaved caspase-3 by Western blot and the degree of cell apoptosis by TUNEL. Results:Prior to cardiac arrest, myocardial function and cardiac injury biomarkers were maintained at the same levels, and no differences were observed among the three groups (all P> 0.05). After resuscitation, myocardial dysfunction and cardiac injury were observed in the CPR and CPR+SV groups, in which the values of SV and GEF were significantly decreased and meanwhile the serum concentrations of cTnI and CKMB were significantly increased when compared with the Sham group (all P< 0.05). However, myocardial dysfunction and cardiac injury were significantly milder in the CPR+SV group, in which the value of SV at 4h post-resuscitation and the values of GEF starting 1h post-resuscitation were significantly increased, and the serum concentrations of cTnI and CKMB were significantly decreased at 4 and 24 h post-resuscitation when compared to the CPR group (all P< 0.05). Tissue measurements indicated that the change of β-catenin signaling pathway and the occurrence of cell apoptosis were observed in the heart at 24 h post-resuscitation in the CPR and CPR+SV groups, which were indicated by significant increases in the protein expression levels of β-catenin, Cyclin D1, c-Myc, cleaved caspase-9, and cleaved caspase-3, and marked elevation in the index of cell apoptosis when compared with the Sham groups (all P< 0.05). However, the expression levels of proteins mentioned above were significantly decreased in the heart at 24 h post-resuscitation and the index of cell apoptosis was significantly reduced in the CPR+SV group when compared to the CPR group (all P< 0.05). Conclusion:SV has the protective role in alleviating post-resuscitation myocardial dysfunction and cardiac injury, in which the protective mechanism is possibly related to the alleviation of cell apoptosis through the inhibition of β-catenin signaling pathway activation.

ABSTRACT

OBJECTIVE To explore the potential mechanism of the effect of Xuebijing injection (XBJ) on neurological function and survival of rats after cardiac arrest (CA)/cardiopulmonary resuscitation (CPR) based on the S-nitrosoglutathione reductase (GSNOR)/S-nitrosoglutathione (GSNO) pathway. METHODS The CA/CPR rat model was established by ventricular fibrillation. Using a sham operation group as control, high-throughput sequencing was employed to analyze and mine the differentially expressed genes (DEGs). Enzyme-linked immunosorbent assay was used to determine the contents of GSNOR and GSNO in the hippocampus; the active components of XBJ were screened and subjected to molecular docking analysis with GSNOR. The rats successfully modeled using the same method were divided into model group (n=30), inhibitor (GSNOR inhibitor) group (n=30), XBJ group (n=30) and XBJ+inhibitor group (n=30), and a sham operation group (n=30) was set up. Neurological function was evaluated and survival status was recorded at 3 hours, 24 hours and 3 days after the first 89) drug intervention. The contents of GSNOR and GSNO in the hippocampus of rats were determined in each group at the 0191) above time points, and the relationship of the contents of GSNOR and GSNO with modified neurologic severity scale (mNSS) score was analyzed. RESULTS GSNOR coding gene was differentially expressed between the model group and the sham operation group. Compared with the sham operation group, GSNOR content increased significantly in the hippocampus of rats in model group, while GSNO content decreased significantly (P<0.05). The active components of XBJ, such as 4- methylenemiltirone and salviolone, could be bound to GSNOR protein, with the binding energy lower than -6 kcal/mol, mainly connected by hydrogen bonds. Animal experiments revealed that mNSS score and GSNOR levels in the hippocampus of rats in the model group were significantly higher than those in the sham operation group (P<0.05), while GSNO levels and survival rate were significantly lower than those in the sham operation group (P<0.05). The above indexes of rats were improved significantly in administration groups, the mNSS score in the XBJ group was significantly lower than that in the inhibitor group, the content changes of GSNOR and GSNO in the inhibitor group were more obvious than those in the XBJ group, and the various indicators in the XBJ+inhibitor group were significantly better than the XBJ group and the inhibitor group (P<0.05). GSNOR content was positively correlated with the mNSS score, and GSNO content was negatively correlated with the mNSS score (P<0.05). CONCLUSIONS XBJ can improve the neurological function of rats and enhance their survival rates after CA/CPR, the mechanism of which may be associated with the down-regulation of GSNOR and the up-regulation of GSNO.

ABSTRACT

Abstract Introduction: Methylene Blue (MB) has been shown to attenuate oxidative, inflammatory, myocardial, and neurological lesions during ischemia-reperfusion and has great potential during cardiac arrest. This study aimed to determine the effects of MB combined with epinephrine during cardiac arrest on myocardial and cerebral lesions. Method: Thirty-eight male Wistar rats were randomly assigned to four groups: the sham group (SH, n = 5), and three groups subjected to cardiac arrest (n = 11 /group) and treated with EPI 20 μg.kg−1 (EPI), EPI 20 μg.kg−1 + MB 2 mg.kg−1 (EPI + MB), or saline 0.9% 0.2 ml (CTL). Ventricular fibrillation was induced by direct electrical stimulation in the right ventricle for 3 minutes, and anoxia was maintained for 5 minutes. Cardiopulmonary Resuscitation (CPR) consisted of medications, ventilation, chest compressions, and defibrillation. After returning to spontaneous circulation, animals were observed for four hours. Blood gas, troponin, oxidative stress, histology, and TUNEL staining measurements were analyzed. Groups were compared using generalized estimating equations. Results: No differences in the Returning of Spontaneous Circulation (ROSC) rate were observed among the groups (EPI: 63%, EPI + MB: 45%, CTL: 40%, p = 0.672). The mean arterial pressure immediately after ROSC was higher in the EPI+MB group than in the CTRL group (CTL: 30.5 [5.8], EPI: 63 [25.5], EPI+MB: 123 [31] mmHg, p = 0.007). Serum troponin levels were high in the CTL group (CTL: 130.1 [333.8], EPI: 3.70 [36.0], EPI +MB: 43.7 [116.31] ng/mL, p < 0.05). Conclusion: The coadministration of MB and epinephrine failed to yield enhancements in cardiac or brain lesions in a rodent model of cardiac arrest.
