Patients with severe traumatic brain injury (TBI) have a higher mortality rate, often dying within a few hours after injury. The management of trauma site, transportation, and early hospital stay is closely related to the outcome of TBI patients. The final success rate of TBI patients varies after different prehospital treatments, and the quality of prehospital treatment for TBI needs to be further improved. Therefore, the TBI prehospital management guideline emerged, and the third version of the guideline was released in April 2023. In order to provide better advice and guidance on the treatment of prehospital TBI, this article interprets the key points of updating the third edition of the prehospital TBI management guideline.
Objective To investigate the relationship between thrombocytopenia after the restoration of spontaneous circulation and short-term prognosis of patients with in-hospital cardiac arrest. Methods The demographic data, post-resuscitation vital signs, post-resuscitation laboratory tests, and the 28-day mortality rate of patients who experienced in-hospital cardiac arrest at the Emergency Department of West China Hospital, Sichuan University between January 1st, 2016 and December 31st, 2016 were retrospectively analyzed. Logistic regression was used to analyze the correlation between thrombocytopenia after the return of spontaneous circulation and the 28-day mortality rate in these cardiac arrest patients. Results Among the 285 patients included, compared with the normal platelet group (n=130), the thrombocytopenia group (n=155) showed statistically significant differences in red blood cell count, hematocrit, white blood cell count, prothrombin time, activated partial thromboplastin time, and international normalized ratio (P<0.05). The 28-day mortality rate was higher in the thrombocytopenia group than that in the normal platelet group (84.5% vs. 71.5%, P=0.008). Multiple logistic regression analysis indicated that thrombocytopenia [odds ratio =2.260, 95% confidence interval (1.153, 4.429), P=0.018] and cardiopulmonary resuscitation duration [odds ratio=1.117, 95% confidence interval (1.060, 1.177), P<0.001] were independent risk factors for 28-day mortality in patients with in-hospital cardiac arrest. Conclusion Thrombocytopenia after restoration of spontaneous circulation is associated with poor short-term prognosis in patients with in-hospital cardiac arrest.
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.
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.
