ObjectiveTo find out the possible factors that may affect the survival time of patients undergoing return of spontaneous circulation (ROSC) within seven days of cardio-pulmonary resuscitation. MethodWe retrospectively collected 20 clinical indicators from 51 patients who underwent ROSC after cardio-pulmonary resuscitation in Emergency Department between August 2013 and February 2015. The indicators included gender, age, duration of cardio-pulmonary resuscitation, blood pressure acquired immediately after ROSC, heart rate, respiration, lactic acid, creatinine, prothrombin time, bilirubin, pH, arterial partial pressure of carbon dioxide, potassium, sodium, blood glucose, atrial natriuretic peptides, leukocyte, platelets, and hemoglobin. Then we analyzed the correlation of these indicators with survival time through Cox regression model. ResultsThe results showed that duration of cardiopulmonary resuscitation[RR=1.053, 95% CI (1.020, 1.088), P=0.002] and systolic blood pressure acquired immediately after ROSC[RR=0.991, 95% CI (0.982, 0.999), P=0.038] significantly affected the survival time of patients after ROSC. ConclusionsDuration of cardiopulmonary resuscitation and systolic blood pressure acquired immediately after ROSC may be useful in predicting the survival time of patients after ROSC.
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.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a salvage therapy for patients suffering cardiac arrest refractory to conventional resuscitation, and provides circulatory support in patients who fail to achieve a sustained return of spontaneous circulation. ECPR serves as a bridge therapy that maintains organ perfusion whilst the underlying etiology of the cardiac arrest is determined and treated. Increasing recognition of the survival benefit associated with ECPR has led to increased use of ECPR during the past decade. Commonly used indications for ECPR are: age<70 years, initial rhythm of ventricular fibrillation or ventricular tachycardia, witnessed arrest, bystander cardiopulmonary resuscitation within 5 min, failure to achieve sustained return of spontaneous circulation within 15 min of beginning cardiopulmonary resuscitation. This review provides an overview of ECPR utilization, recent outcomes, risk factors, and complications of ECPR. Identifying ECPR indications, rapid deployment of extracorporeal life support equipment, and high-quality ECPR management strategies are of paramount importance to improve survival.
ObjectiveTo analyze the long-term effect on cardiopulmonary resuscitation skill between video-led and scene simulation training and traditional instructor-led courses in medical student with eight-year program.MethodsNinety-nine medical students with eight-year program who studied in Peking Union Medical College were trained in cardiopulmonary resuscitation skill from January to February 2018. They were randomly divided into two groups, 53 students participated in basic life support course training, which belonged to video-led and scene simulation training as the trial group, and 46 students were trained by traditional instructor-led courses as the control group. In January 2019, the above 99 students were re-evaluated for cardiopulmonary resuscitation, and the outcome of cardiopulmonary resuscitation skill test in total scores and sub-items scores between two groups were compared. The data were analyzed using t test and Wilcoxon rank sum test.ResultsThe total average scores of the trial group (8.02±1.11) was higher than that of the control group (6.85±1.50) (P<0.05). The sub-items scores of the trial group in the three aspects of on-site assessment, chest compressions and simple respirators (1.64±0.37, 3.38±0.46, 1.52±0.58) were higher than those of the control group (1.33±0.45, 2.80±0.76, 1.19±0.58) (P<0.05). In terms of opening airway, there was no significant difference in scores between the two groups (1.02±0.47 vs. 1.10±0.45, P>0.05). The excellent rate of the trial group (60.3%) was significantly higher than that of the control group (30.4%) (P<0.05), and the unqualified rate (5.6%) was significantly lower than that of the control group (21.7%) (P<0.05).ConclusionsThe video-led and scene simulation training has a better effect on cardiopulmonary resuscitation skills acquisition and long-term maintenance than traditional instructor-led courses for medical student with eight-year program.
Although the survival rate reported in each center is different, according to the present studies, compared to conventional cardiopulmonary resuscitation (CCPR), extracorporeal cardiopulmonary resuscitation (ECPR) can improve the survival rate of cardiac arrest patient, no matter out-of-hospital or in-hospital. The obvious advantage of ECPR is that it can reduce the nervous system complications in the cardiac arrest patients and improve survival rate to hospital discharge. However, ECPR is expensive and without the uniformed indications for implantation. The prognosis for patients with ECPR support is also variant due to the different etiology. If we want to achieve better result, the ECPR technology itself needs to be further improved.
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.
The inspiratory impedance threshold device (ITD) was put forward by Lurie in 1995, and was assigned as a class Ⅱa recommendation by the International Liaison Committee on Resuscitation (ILCOR) resuscitation guidelines in 2005. The ITD is used to augment negative intrathoracic pressure during recoil of the chest so as to enhance venous return and cardiac output, and to decrease intracranial pressure. In the recent years many researches on the ITD have been1 carried out, but all the researches can not take out a clear evidence to support or refute the use of the ITD. This paper introduces the structure and working principle of the ITD in detail, the research results and the debates about the use of the ITD for the past years.
