Coming from the Patient side of things. was recently in to get my gallbladder out, I have a multitude of health problems. Ended up staying 2 nights. second night the nurse said she was going to give me this drug via orders from on duty head surgeon (not my doctor) looked it up on my phone and refused it. i know it's a good precaution.... Unless you are a patient with mastocytosis or any type of mast cell disease. we carry an usually high natural Endogenous Heparin level.... Mine is at the same level as someone who receives heparin regularly. this could have been disasterous. of course my hospital also requires me to beg to have my cortisol checked halfway to an adrenal crisis, been down as low as 0.4 when they finally check. so I've learned to just not trust any facility or docs in charge, they don't read my chart.
