Ultrasound in Diagnosing Torso Injuries
In patients with torso injuries, especially the ones with suspicion of injuries of intraabdominal organs, prompt making of diagnosis and decision about further management plays crucial role. Nowadays ultrasound is the first imaging technique used in Emergency Room in such cases.
The aim of the study. Assessment of the value of ultrasound in diagnostics of patients with torso injuries, especially in qualification for operative or conservative treatment.
Material and methods. 808 patients with an average age of 44.92 with torso injuries treated in the Department of Emergency Medicine and Multiple Injuries of 2nd Chair of General Surgery, Medical College of Jagiellonian University from 2004 to 2008, in whom ultrasound according to FAST protocol was used were included in the study. Results of sonographic examinations were verified during surgical operation (in patients treated surgically), or with the use of computed tomography (in patients treated conservatively), or on the basis of post-mortem examination (in patients who died due to sustained injuries), or on the basis of clinical course of hospitalization.
Results. Sensitivity of ultrasound in the study material amounted to 90.43%, while specificity as much as 99.44%. Positive predictive value (so percentage of patients with truly positive result amongst the patients with positive result of diagnostic test) for whole study material was 95.5 while negative predictive value was 98.75.
Conclusion. Results of the study confirm that ultrasound constitutes imaging technique of unique value in diagnostics of patients suffering from torso injuries, especially the circulatory unstable ones, allowing for precise qualification for prompt surgery.
