[Ultrasonic diagnosis of blunt abdominal injuries].

In 190 patients with blunt abdominal trauma a sonogramm was made after admission. In 25 cases blood and fluid had accumulated in the abdominal cavity. In 24 cases diagnosis was correct. In patients who had organ lesions without fluid in the abdominal cavity the injured organ could be determined in 22 out of 25 cases. The danger of late liver and spleen ruptures existed in patients with organ hematomas. False positive results regarding fluid accumulation in the peritoneal cavity were found in 3 out of 165 patients.
