My son is having surgery soon for his reflux. He has confirmed food allergies to: CORN, Wheat, Soy, Eggs as well as nuts of any kind and fish of every kind. His last surgery he ended up in the ICU and I suspect this may have been due to the IV fluids/anesthesia containing derivatives of what he is allergic to. He can't even tollerate hypoallergenic formulas made from hydrolized corn. Any ideas on what I can do to help him get through this, any corn free IV fluids to suggest to the medical professionals. He is tube fed, and only just found that he will tollerate organic pediasmart dairy (corn free, made from brown rice syrup rather than corn syrup).
