[Trauma Analysis in Patients Examined by Whole-Body CT]

Area of Science:

• Radiology
• Trauma Surgery
• Emergency Medicine

Background:

• Whole-body CT (WBCT) is a crucial diagnostic tool in polytrauma.
• The utility and necessity of WBCT require ongoing evaluation due to radiation exposure.
• Standardized injury scoring systems aid in trauma assessment.

Purpose of the Study:

• To evaluate the diagnostic yield of whole-body CT in trauma patients.
• To determine if the number of whole-body CT examinations can be reduced.
• To compare outcomes between high- and low-energy trauma injuries.

Main Methods:

• Retrospective analysis of 338 patients undergoing whole-body CT over one year.
• Data collection included demographics, trauma mechanisms, and injury details.
• Injuries were assessed using the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS), categorized by energy levels.

Main Results:

• The median age was 48 years, with 75% males; road accidents (53%) and falls (25%) were common causes.
• Higher Injury Severity Scores (ISS) were associated with older age and high-energy traumas (p=0.002).
• Negative CT findings were observed in 5 low-energy and 9 high-energy trauma cases.

Conclusions:

• High-energy trauma is linked to greater injury severity and more negative CT findings compared to low-energy trauma.
• The findings suggest that selective CT imaging may be adequate in certain trauma cases.
• Optimizing WBCT use can reduce radiation exposure while maintaining diagnostic accuracy in trauma care.
