[Multislice CT in diagnostic work-up of polytrauma].

BACKGROUND

In severely injured patients, diagnostic procedures should be as brief as possible. With the use of spiral CT technology, the time required for diagnosis is minimized.

QUESTION

Do severely injured patients benefit when primary diagnostic examinations are completed in less than 30 min? How much time is required for primary emergency department (ED) care and how much in the CT scanner?

MATERIAL AND METHODS

Between 31 July 2001 and 31 December 2003, severely injured patients with ISS scores over 16 underwent total body spiral CT scans (Siemens Somatom Volume Zoom Multislice CT) after initial ultrasonography. One hundred patients (M:F=25:75) with an average age of 42 years (range: 3-81 years) were evaluated retrospectively. The average ISS score was 32.8+/-12 points (range: 17-75 points).

RESULTS

The average time in the ED, prior to CT, was 33+/-14 min. The CT scans lasted 16+/-5 min and the total diagnostic time was 48+/-14 min. Fifty percent of patients were taken immediately to the operating room. The mortality rate in hospital was 13%. The average hospital stay was 30 days, with an average ICU stay of 10 days.

CONCLUSION

The shorter the time spent in the ED, the shorter the stays in ICU and in total hospitalization were, regardless of injury severity. With structured management and shortening of diagnostic time with spiral CT, the time in the ED was decreased from 85 to 48 min.
