Objective To explore factors affecting the shunt safety of patients in emergency intensive care unit (EICU), construct a shunt safety evaluation model, and evaluate its prediction effectiveness, so as to provide a theoretical basis for the decision-making of shunt safety in EICU. Methods The demographic data, vital signs, laboratory examinations and other indicators of patients transferred to the general ward from the EICU of West China Hospital of Sichuan University from 0:00 on August 1, 2019 to 23:59 on May 31, 2021 were collected and analyzed. The short-term poor prognosis after being transferred out of the EICU was regarded as the end-point event. Of the patients, 70% were randomly selected as the model construction cohort, and 30% were the model validation cohort. In the model construction cohort, multivariate logistic regression analysis was used to screen the influencing factors affecting shunt safety, and the shunt safety evaluation model of patients in EICU was constructed. In the validation cohort, receiver operating characteristic curve was used to evaluate the effectiveness of the model in evaluating the shunt safety of patients in EICU. Results A total of 582 patients were included, of whom 59 patients (10.1%) had a poor short-term prognosis. Multivariate logistic regression analysis showed that the patients’ respiratory rate when leaving the EICU [odds ratio (OR)=0.863, 95% confidence interval (CI) (0.794, 0.938), P=0.001], Glasgow Coma Scale scores [OR=1.575, 95%CI (1.348, 1.841), P<0.001], albumin [OR=1.137, 95%CI (1.008, 1.282), P=0.036], prothrombin time [OR=0.956, 95%CI (0.914, 1.000), P=0.048] were the influencing factors of shunt safety. Based on the above indicators, a shunt safety evaluation model for patients in EICU was created. The area under the curve for the shunt safety assessment model to predict poor short-term prognosis was 0.815, the best cut-off value was 4 points, the sensitivity was 93.3%, and the specificity was 61.5%. Conclusions The patients’ respiratory rate when leaving EICU, Glasgow Coma Scale scores, albumin and prothrombin time are factors affecting the shunt safety for patients in EICU. The shunt safety assessment model can better predict the short-term poor prognosis of patients transferred from EICU to general ward.
Since the outbreak of the coronavirus disease 2019, the incidence and mortality of cardiac arrest have increased significantly worldwide, and the management of cardiac arrest is facing new challenges. The European Resuscitation Council issued the 2021 European Resuscitation Council Guidelines in March 2021 to update the important parts of cardiopulmonary resuscitation and added recommendations for the management of cardiopulmonary resuscitation during the coronavirus disease 2019 epidemic. This article will compare the difference between this guideline and the 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care and integrate some key points, review literature and then summarize the latest research progress in cardiopulmonary resuscitation since the outbreak of the coronavirus disease 2019 epidemic. The content mainly involves cardiopulmonary resuscitation during the coronavirus disease 2019 epidemic, early prevention, early recognition, application of new technologies, airway management, extracorporeal cardiopulmonary resuscitation and post-resuscitation treatment.
The treatment of organ function damage secondary to return of spontaneous circulation in patients with cardiac arrest is an important part of advanced life support. The incidence of lung injury secondary to return of spontaneous circulation in patients with cardiac arrest is as high as 79%. Understanding the characteristics and related mechanisms of lung injury secondary to return of spontaneous circulation in patients with cardiac arrest, and early identification and treatment of lung injury secondary to return of spontaneous circulation are crucial to the clinical treatment of patients with cardiac arrest. Therefore, this article reviews the research progress on the characteristics, risk factors, mechanisms and treatment of lung injury secondary to return of spontaneous circulation in patients with cardiac arrest, in order to provide a reference for the research and clinical diagnosis and treatment of lung injury secondary to return of spontaneous circulation in patients with cardiac arrest.
Elderly patients account for 80% of cardiac arrest patients. The incidence of poor neurological prognosis after return of spontaneous circulation of these patients is as high as 90%, much higher than that of young. This is related to the fact that the mechanism of hippocampal brain tissue injury after ischemia-reperfusion in elderly cardiac arrest patients is aggravated. Therefore, this study reviews the possible mechanisms of poor neurological prognosis after return of spontaneous circulation in elderly cardiac arrest animals, and the results indicate that the decrease of hippocampal perfusion and the number of neurons after resuscitation are the main causes of the increased hippocampal injury, among which oxidative stress, mitochondrial dysfunction and protein homeostasis disorder are the important factors of cell death. This review hopes to provide new ideas for the treatment of elderly patients with cardiac arrest and the improvement of neurological function prognosis through the comparative analysis of elderly and young animals.
The American Heart Association and other six major associations jointly released AHA/ACC/ASE/CHEST/SAEM/SCCT/SCMR Guideline for the Evaluation and Diagnosis of Chest Pain for the first report on October 28th, 2021. This guideline stresses the risk stratification and the diagnostic workup of acute chest pain, considers the cost-effectiveness of low-risk chest pain diagnosis and examination, and recommends sharing decisions with patients. This guideline mainly involves the initial evaluation of chest pain, choosing the right pathway with patient-centric algorithms for acute chest pain, and the evaluation of patients with stable chest pain. This review makes a detailed interpretation of the recommended points of the guideline through reviewing the literature.
Objective To analyze the current situation and demand of emergency and critical care training for medical staff in plateau areas, and to provide a reference for further emergency and critical care training for medical staff in plateau areas. Methods From July 1, 2018 to July 30, 2020, medical staff (including physicians, nursing staff, and other medical staff) from hospitals in various regions of Tibet were surveyed anonymously, to investigate the content and demand of medical staff in plateau areas receiving emergency and critical care training. The content and demand of medical staff from different levels of hospitals receiving emergency and critical care training were further compared. Results A total of 45 questionnaires were distributed in this study, and a total of 43 valid questionnaires were collected, with an effective response rate of 95.6%. The average age of medical staff was (35.67±9.17) years old, with a male to female ratio of 1∶1.5. The proportion of tertiary, secondary, and lower level hospitals to which medical staff belong were 23.3%, 27.9%, and 48.8%, respectively. The number and proportion of medical staff receiving training on chest pain, heart failure, stroke, gastrointestinal bleeding, respiratory failure, metabolic crisis, and sepsis diseases were 25 (58.1%), 25 (58.1%), 24 (55.8%), 23 (53.5%), 20 (46.5%), 14 (32.6%), and 12 (27.9%), respectively. The number and proportion of medical staff who believed that training in the heart failure, respiratory failure, metabolic diseases, stroke, gastrointestinal bleeding, chest pain, and sepsis needed to be strengthened were 38 (88.4%), 36 (83.7%), 35 (81.4%), 34 (79.1%), 34 (79.1%), 33 (76.7%), and 29 (67.4%), respectively. Thirteen medical staff (30.2%) hoped to acquire knowledge and skills through teaching. There were no statistically significant differences in gender, age, job type, professional title, and department type among medical staff from tertiary, secondary, and lower level hospitals participating in the survey (P>0.05). The proportion of medical staff in hospitals below secondary receiving training on chest pain was lower than that in second level hospitals (38.1% vs. 91.7%). The proportion of medical staff in hospitals below secondary receiving training on heart failure was lower than that in secondary and tertiary hospitals (38.1% vs. 75.0% vs. 80.0%). The proportion of medical staff in hospitals below secondary receiving training on respiratory failure was lower than that in tertiary hospitals (28.6% vs. 80.0%). The demand for sepsis training among medical staff in hospitals below secondary was higher than that in tertiary hospitals (85.7% vs. 30.0%). There was no statistically significant difference in the other training contents and demands (P>0.05). Conclusion The content of critical care training for medical staff in plateau areas cannot meet their demands, especially for medical staff in hospitals below secondary. In the future, it is necessary to strengthen training support, allocate advantageous resources to different levels of hospitals, expand the scope of training coverage, and enrich training methods to better improve the ability of medical personnel in plateau areas to diagnose and treat related diseases.
American Heart Association issued American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in October 2020. A sixth link, recovery, has been added to both the adult out-of-hospital cardiac arrest chain and in-hospital cardiac arrest chain in this version of the guidelines to emphasize the importance of recovery and survivorship for resuscitation outcomes. Analogous chains of survival have also been developed for adult out-of-hospital cardiac arrest and in-hospital cardiac arrest. The major new and updated recommendations involve the early initiation of cardiopulmonary resuscitation by lay rescuers, early administration of epinephrine, real-time audiovisual feedback, physiologic monitoring of cardiopulmonary resuscitation quality, double sequential defibrillation not supported, intravenous access preferred over intraosseous, post-cardiac arrest care and neuroprognostication, care and support during recovery, debriefings for rescuers, and cardiac arrest in pregnancy. This present review aims to interpret these updates by reviewing the literature and comparing the recommendations in these guidelines with previous ones.
