Our infusion center also collects stem cells for bone marrow transplant. The cellular techs start a 16 gauge peripheral IV in an antecubital and a 18 gauge in either the hand or the wrist for return. The RN is responsible for monitoring the pt and giving medications. ACD is used during the collection and can deplete the calcium. Our MD wants us to replace the calcium thru the 18 gauge in the hand/wrist. The standing order is 500 mg Calcium Gluconate IVP followed by 2 grams in 250 cc NS over 4 hours. Cellular states this is ok because our policy states calcium is only a vesicant if injected IM or Sub Q. My thought is that if the hand IV infiltrates, that is infact sub Q. What would you do??
