</p>
<ul>
<li>
Use of FAST is less common in pediatric trauma than in adult trauma</li>
<li>
FAST in pediatric trauma has a lower negative predictive value than in adults
<ul>
<li>
1/3 of pediatric patients with hemoperitoneum on CT will have a negative FAST</li>
<li>
Lowest sensitivity and specificity is in the under 2 years age group</li>
</ul>
</li>
<li>
A 2017 randomized clinical trial of ~900 patients showed no difference in clinical care, use of resources, or length of stay in hemodynamically stable children who received FAST + standard trauma evaluation versus standard trauma evaluation alone</li>
<li>
There may be a role for FAST as a screening in patients with low suspicion for intraabdominal injury in conjunction with labs and physical exam, but this has not been fully explored</li>
</ul>
<p>
Bottom line: A positive FAST warrants further workup and may be helpful in the hemodynamically unstable pediatric trauma patient, but a negative FAST does not exclude intraabdominal injury and evidence for performing FAST in hemodynamically stable pediatric patients is limited.</p>
