A simple ultrasonographic method of fluid quantification, which counted the
number of fluid recesses, was developed to predict the severity of injury
after blunt abdominal trauma. From 1994 to 1998, 2,693 screening
ultrasonographic examinations were performed for blunt abdominal trauma. Of
this group, 2,499 patients had a fluid score of 0 (no fluid), and 1.4% had
injuries (0.4% requiring surgery); 110 had a score of 1 (fluid in a single
examined region), and 59% had injuries (13% requiring surgery); 33 had a
score of 2, and 85% had injuries (36% requiring surgery); 30 had a score of
3, and 83% had injuries (63% requiring surgery); and 21 had a score of 4,
and 95% had injuries (81 % requiring surgery). Patients with scores of 3 or
greater had significantly higher rates of injury (P < .002) and injury
requiring surgery (P < .0001) than patients with lower scores. The
ability to predict injury severity on the basis of a simple
ultrasonographic scoring system should expedite treatment of patients with
severe trauma.
