Not Checking Where the Probe is Externally on the Patient

Оглавление

This is really Part 2 of the previous paragraph. A few years ago, while I was performing Global FAST imaging on dolphins, the concept proved most helpful. Without goggles showing the ultrasound screen, two people were needed for imaging – one on the dock monitoring the ultrasound screen and directing the sonographer who was in the water with the dolphin, unable to see the ultrasound screen. Paying attention to external landmarks helped guide the sonographer to the AFAST target organs (and all of Global FAST) efficiently and confidently.

The same holds true with our small animal and exotic patients. Pay attention to where the probe is externally on your patient, double‐checking between the ultrasound screen and the probe's external location. Look at your patient! For example, if you can't find the urinary bladder then slide toward the patient’s pubis slightly off midline in lateral recumbency or along midline when standing or sternal. Some other examples – the gallbladder is right of midline in both dogs and cats so the probe has to be directed to that side of your patient; the TFAST chest tube site (CTS) view generally takes you to the caudodorsal transition zone, thus helping to prevent mistaking abdominal structures for lung pathology; and the kidneys are close to the caudal vena cava and aorta attached by their short renal artery and veins.
