便携式超声在院前创伤急救中的应用研究OA

Objective To investigate the application value of portable ultrasound in pre-hospital trauma emergency care.Methods A total of 79 trauma patients with pre-hospital trauma index(TI)≤16 scores admitted to the 923rd Hospital of the Joint Logistics Support Force from June 2024 to June 2025 were enrolled as the research subjects.All patients underwent trauma assessment using TI alone and combined with pre-hospital ultrasound,with the final in-hospital diagnosis serving as the gold standard for trauma evaluation.The core indicators of the two assessment methods were compared in the overall cohort of 79 patients,including the accuracy of trauma assessment,near referral rate,distant referral rate,and appropriate triage and transport rate.Patients were then stratified by TI score into the TI<10-score group(n=46)and the TI≥10-score group(n=33)for further comparison of the evaluation efficacy of TI alone versus combined with pre-hospital ultrasound in pre-hospital trauma.Results Compared with TI alone,the addition of pre-hospital ultrasound showed significantly higher accuracy of trauma assessment,appropriate triage and transport rate,and distant referral rate,but a lower near referral rate,with statistically significant differences(P<0.05).Stratified analysis revealed that no statistically significant differences were found between TI alone and the addition of pre-hospital ultrasound in terms of accuracy of trauma assessment,appropriate triage and transport rate,distant referral rate,or near referral rate in the TI<10-score group(P>0.05).In contrast,in the TI≥10-score group,all the above indicators assessed by the addition of pre-hospital ultrasound were superior to those assessed by TI alone,with statistically significant differences(P<0.05).The main influencing factor for TI assessment was thoracic and abdominal trauma,followed by unconsciousness and incomplete chief complaint,unknown mechanism of trauma,femoral fracture with pronounced swelling,and tachycardia.Conclusion The addition of pre-hospital ultrasound shows significantly better overall performance in trauma assessment and triage and transport guidance than TI alone for pre-hospital trauma patients with a TI≤16 scores.It has particularly prominent advantages in improving the accuracy and appropriateness of triage for patients with moderate to severe trauma(TI≥10 scores),and also has important clinical value for optimizing pre-hospital trauma care.
