FAST IS Fast, And FAST Is Last!

Ever been in a trauma activation where it seems like the first thing that happens is that someone steps up to the patient with the ultrasound probe in hand? And then it takes 5 minutes of pushing and prodding to get the exam done?

Well, it’s not supposed to be that way. The whole point of adhering to the usual ATLS protocol is to ensure that the patient stays alive through and well after your exam. And FAST is not part of the primary or secondary surveys, it is an adjunct.

As always, there are a few exceptions to the rule above.

  • If an unstable patient arrives without an obvious source of bleeding, FAST of the abdomen should be able to detect if a large hemoperitoneum is present. This will expedite the patient’s transfer to the OR.
  • A patient in cardiac arrest may benefit from a quick FAST to determine if cardiac activity is present. If not, it may be time to terminate resuscitation.

Bottom line: With the exceptions noted above, always complete the ATLS primary and secondary surveys first. Then pull out the ultrasound machine, but be quick about it. If it takes more than about 60 seconds to do the exam, someone probably needs a little more practice.
