Say, a patient comes in with exacerbation of heart failure. He was previously well controlled on a good drug regimen including oral lasix. It is a tendency to give diuretics (Like furosemide) in the ED intravenously (Even though they can tolerate oral meds). Ever thought why?
Well, congestive heart failure not only causes edema of the legs and fluid retention in the lungs but also causes gut edema.

Well, congestive heart failure not only causes edema of the legs and fluid retention in the lungs but also causes gut edema.
In patients with CHF there may be decreased intestinal perfusion, reduced intestinal motility, and also intestinal mucosal edema, which will reduce the diuretic absorption, and hence diuretic delivery to the kidney and diuretic excretion rate [1]. This is why the route of diuretic administration is changed in CHF exacerbation.
One of the symptoms of intestinal edema is early satiety (It was present in my patient today) so you can ask this in the next patient with CHF that comes to the ED.
That's all!
Be happy with the person you are :)
