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 International Liaison Committee on Resuscitation published the 2022 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations in Circulation, Resuscitation, and Pediatrics in November 2022. This consensus updates and recommends important aspects of cardiopulmonary resuscitation based on recently published resuscitation evidence. Herein, we interpret the consensus focusing on adult cardiopulmonary resuscitation including basic life support (ventilation techniques, compressions pause, transport strategies during resuscitation, and resuscitation procedures in drowning), advanced life support (target temperature management, point-of-care ultrasound as a diagnostic tool during cardiac arrest, vasopressin and corticosteroids for cardiac arrest, and post-cardiac arrest coronary angiography), cardiopulmonary resuscitation education/implementation/team (survival prediction after resuscitation of patients with in-hospital cardiac arrest, basic life support training, advanced life support training, blended learning for life support education, and faculty development approaches for life support courses) and recovery positions on rescue scene. This consensus provides important guidance for clinical practice and clear hints for the development of clinical research.
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 updated the guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care in November 2019. This focused update incorporates the systematic review conducted by the International Liaison Committee on Resuscitation, an expert group consisting of hundreds of international resuscitation scientists, to identify the new evidence supporting the basic and advanced life support and first aid in emergency medical care. This focused update involves the life chain of CPR (dispatcher-assisted CPR and cardiac arrest centers), advanced cardiovascular life support (advanced airways, vasopressors, and extracorporeal CPR), and first aid for presyncope. This present review aims to interpret these updates by reviewing the literature and comparing the recommendations in this update with previous guidelines.
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.
