Cardiac and regional hemodynamic interactions between halothane and nitric oxide synthase activity in dogs.

abstract：BACKGROUND:Intensive care unit (ICU) patients often need blood transfusion, but no reliable predictors of transfusion requirements are available at ICU admission. The authors hypothesized that ICU patients with functional iron deficiency may be at higher risk for developing anemia, requiring blood transfusion. Their ob...
