i do agree...that a sonogrpher is always the best choice and also the first choice if he's available 24/7...but no harm in doing a FAST urself and picking up the gross abnormalities...and taking the patient early for a laparotomy...rather than either making the patient go thru DPL or instead wait for a sonographer off hours....or even overnight in some hospitals.....just so that he can pick up some finer abnormalities...
