Abstract
The use of ultrasound examination of the lungs gives an idea of the lung tissue, lesion volume and affect the tactics of treatment. However, different lungs ultrasound examination protocols gives the opportunity to get different data. Using ROC analysis by standard of computed tomography were compared the sensitivity and specificity of ultrasound techniques, specifically the protocol for bedside ultrasound examination of the lungs, as well as the 4-zone and 9-zone protocols in the diagnosis of pneumonia. It was revealed that the sensitivity of the researched protocols was 97, 93 and 97%, respectively, specificity – 80, 80 and 90%, respectively. At the same time, the modified 9-zone scanning protocol makes it possible to more accurately search for pneumonic lesions, not only taking into account the lobar structure, but also taking into account the segments of the lungs. The sensitivity of the protocols of bedside ultrasound examination of the lungs, 4-zone and 9-zone in the diagnosis of pneumonic lesions in shares was 69, 80 and 97%, respectively, specificity – 60, 62 and 71%, respectively. The sensitivity of the protocols of bedside ultrasound examination of the lungs, 4-zone and 9-zone in the diagnosis of pneumonic lesions in segments was 73, 68 and 93%, respectively, specificity – 66, 68 and 92%, respectively. In the diagnosis of pneumonia, it is possible to use any of the three protocols with high specificity and sensitivity. The modified 9-zone scanning protocol makes possible to diagnose pneumonic lesions taking into account the lobar structure and taking into account the segmental structure of the lungs with higher sensitivity and specificity.
