In short, the answer is "yes". However, it will be up to your surgeon whether he feels comfortable with this. It is impossible to say how much dissection will be needed to achieve a nice result for you without a formal evaluation. The less dissection require, the greater the chance your surgeon will feel confident not using adrenaline. As stated by other comments, adrenaline helps to minimize bleeding during and immediately after surgery. This concentration can be diluted to a point where it still provides this effect but has less chance of causing problems with your cardiovascular system. In the end, its best to meet with a qualified surgeon and discuss your concerns and see what they can provide as a solution. You have options here for sure... Good Luck! Dr. M
