I'll save time by not writing the details here. If you want to see exactly what happened to us, google "Anaphylactic Reactions to Isosulfan Dye During Sentinel Node Lymphadenectomy for Breast Cancer." The case study is precisely what happened to us right down to the vasopressor titration. Freaky similar case. I did not realize that the relative incidence of this happening were so high. Our patient is fine and on her way home, and we handled it spot on...but I'll tell you now, I was second guessing a lot of what we were doing because this is not something you deal with often. How prepared are you to handle anaphylaxis? Read the article. Got to go do a block...I'll return to discuss details of the case this afternoon.
