Role of chest beside ultrasonography in the diagnosis of Traumatic lung contusion in people under 18 years

Abstract

Chest wall damage is not common in children, but it is due to the powerful mechanisms that cause serious injury. It is absorbed by the chest wall and more force is transmitted to the organs inside the chest. Therefore, damage to the chest (such as lung contusion) often occurs without visible damage to the chest wall, Objectives: Method and materials: In this prospective cross-sectional study, 185 children with chest trauma were enrolled. The required information including age, sex, cause of trauma, GCS at admission, vital signs at the time of emergencies, duration of the accident to the emergency department were obtained using a researcher-made questionnaire. Chest ultrasound was performed by a thesis assistant in emergency medicine who had a good understanding of how to perform chest ultrasound in the first year of residency in a 12-hour course under the supervision of radiology professors. Patterns of lung trauma consisted of two patterns: 1) Alveolar Intrauterine Syndrome (AIS) and 2) Peripheral Parenchymal Lesions (PPL). The chest CT scan was interpreted by a radiologist who was unaware of the results of the study. In fact, the radiologist was unilateral. it placed. Data were analyzed using SPSS 16.0 software. Results:Of the 185 patients enrolled in the study, 148 had pulmonary contagion, which was confirmed by chest CT scan as the standard gold standard. Percentage, positive predictive value was 97.5%, negative predictive value was 90% and diagnostic accuracy in general was 96%. 100% negative predictive value was 76.92% and diagnostic accuracy was 94%. Overall sonographic diagnostic sensitivity Efficacy was considered for pulmonary contusion 97.5%, diagnostic specificity 90%, positive predictive value 97.5% and negative predictive value 90% and overall diagnostic accuracy of 96%.
