Abstract: Objective To explore the application effect of portable ultrasound e-FAST technology in the pre hospital treatment of batch wounded soldiers in military civilian joint hospitals．Methods Eighty batch wounded patients admitted to the emergency department of 988 Hospital from May 2021 to October 2023 were selected,all of whom underwent military civilian joint pre hospital treatment．They were divided into an observation group and a control group according to different treatment plans,with 40 patients in each group．The control group received CRAMS scores at the treatment site for routine first aid treatment,CT scans after ambulance return to the hospital for corresponding injury treatment,the observation group received CRAMS scores at the treatment site for routine first aid treatment,and the pre-hospital attending physician used a portable ultrasound instrument to examine the corresponding parts on site or in the ambulance according to the e-FAST process．After preliminary diagnosis,corresponding injury treatment was carried out．The treatment effects of the two groups of patients were compared,and the diagnosis time and initial diagnosis of the two groups of patients were compared．The time from medical contact to entering the operation room,the compliance rate of discharge and admission diagnoses,the CRAMS score before and after treatment,and the success rate of rescue with CRAMS ≤ 8 for both groups of patients were compared．Results The effective rate of treatment in the observation group was 95.0%,while in the control group it was 85.0%,which difference was not statistically significant（χ²=2.222,P=0.136）．The time to diagnosis（13.56±2.36）min,time to the operating room（30.42±8.99）min were shorter than that in the control group[（23.64±5.69）,（52.27±12.60）min],with significant difference（t=10.349,8.928,P<0.05）．The consistency between the admission diagnosis and the definitive diagnosis at discharge of the observation group patients was 97.5%,while the consistency of the control group patients was 95.0%．There was no significant difference between the groups（χ²=0.346,P=0.556）．After treatment,the CRAMS scores of both groups of patients increased,the observation group（9.87±2.62）was higher than that of the control group（8.60±2.98）（t=2.024,P=0.046）．The success rate of CRAMS ≤ 8 rescue in the observation group was 97.50%,while the success rate in the control group was 85.00%．The success rate of CRAMS ≤ 8 rescue in the observation group was higher than that in the control group（χ²=3.914,P=0.048）．Conclusions This study focuses on the joint treatment of batch wounded soldiers by military and civilian forces,aiming at the development path of military civilian integration strategy in military hospitals．The application scope of portable ultrasound e-FAST has been moved forward,which significantly improves the pre hospital treatment ability of emergency personnel and improves the success rate of rescue．It is worth clinical reference．
