WebIndications for deferoxamine infusion include significant clinical signs of iron toxicity, metabolic acidosis, shock, serum iron levels >500 μg dl −1, and/or an X-ray positive for multiple pills. Deferoxamine should be infused intravenously at a starting rate of 15 mg kg −1 h −1, not to exceed 1 g h −1, over a total of 6 h and then reevaluated. WebChelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1] [2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.
