In modern war, the advancement of military technology and weapons results in the gathering of severe casualties and increases the difficulty in field rescue, which brings great challenges for medical staff to complete the assessment, classification and rescue tasks in a short time. Ultrasonic examination can easily and quickly screen and diagnose the wounded in battlefield environment or field hospital, and improve the efficiency of classification and treatment. Ultrasonic visualization technology can improve the screening and diagnosis efficiency of war trauma patients with chest, abdomen, craniocerebral and skeletal soft tissue injuries. It also provides convenience for emergency treatment of war trauma patients and improves the emergency treatment effects. This paper reviews the application of ultrasonic visualization technology in the evaluation and emergency treatment of war trauma patients.
