Objectives: FAST is "gold standard" of emergency US for abdominal trauma. However, in the experience of war in Ukraine in 2014-2022, we had seen that the FAST has a few "blind spots", in particular, regarding the diagnosis of colon damage and retroperitoneal hematomas.

Methods: We had added a few criteria and positions to the FAST for assisting injuried with combat abdominal trauma:

- examination of the right  iliac region with assessment of the caecum diameter;

- assessment of retroperitoneal hematoma was added to examination in the standard positions of the FAST.

As we found earlier in a case series, a decrease in the diameter of the cecum of less than 40mm is a specific sonographic sign of colon injury(CI). We decided to use this criterion to detect CI.

Verification of the effectiveness of proposed additions to the standard FAST was carried out in 2 stages:

1. Comparison of retrospective data on the use of the standard FAST procedure during the Joint Forces Operation 2014-2021 and the improved procedure, which we began to apply separately in January 2022 and systematically - after 24-February-2022.

2. Comparison of results for FAST with and without additional criteria for assessment injuried with PAT received after 24-February-2022.

Results:

Advanced FAST

(after 24-Feb-2022 y.)

n=1179

Rate of intraabdominal

82,4%(1657 cases)

92,2%(1087 cases)

Early mortality rate 7%(141 cases) 5,4%(64 cases)
Early complications rate 12%(241 cases) 6%(71 cases)
 

Standard FAST

Advanced FAST

(after24-Feb-2022 y.)

92,2%(1087 cases)

Conclusions:

1. Improving of emergency abdominal ultrasound in accordance with the requirements of military medicine is a necessary measure that reduces early mortality and complications among the injuried with PAT.

2. Proposed changes are easy-to-implement additions to the standard FAST procedure that allow detected of colon damage and assess of retroperitoneal hematoma.

3. The use of the improved protocol has a positive effect on the results of treatment for injuried with PAT, reducing early mortality(p-value<0.05).
