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.
