Abstract：Objective To study the related factors affecting the success of cardiopulmonary resuscitation(CPR)in critical patients with cardiac arrest during pre-hospital transport,and to provide reference for safe pre-hospital transport of critical patients.Methods The data of critical patients with cardiac arrest during transportation from January 1,2014 to December 31,2021 were retrospectively analyzed.The patients were divided into the successful resuscitation group and the failed resuscitation group.The data of case number,disease type,past history,vital signs,cardiopulmonary resuscitation measures,and outcomes were analyzed.Results During the 8 years,363 critical patients with sudden cardiac arrest during transportation were treated,while 100 patients were successfully resuscitated,and the successful rate was 27.55％(100/363).In the successful resuscitation group and the failed resuscitation group,there were significant differences in age,address,previous medical history,Grasse's coma score,malignant arrhythmia,rescue measures,on-the-spot stay time,cardiac arrest time,and on-the-train time(P＜0.05).Neurological Disorder,GCS,defibrillation,use of dopamine before cardiac arrest,and the time between cardiac arrest and vehicle loading were independent predictors of resuscitation of critical patients during emergency transport(P＜0.05).Conclusion A history of neurological disorder,higher GCS,defibrillation during resuscitation,and use of dopamine before cardiac arrest are important factors for resuscitation:the longer the patient was transported to an emergency vehicle,the less successful the resuscitation.It is very important to strengthen the capability of pre-hospital emergency medical staff to deal with the situation on the spot,to prepare the patients well before transportation,and to ensure the high-quality resuscitation during the transportation of cardiac arrest patients.
