Removing Sutures and Staples:
answer
Removing staples and sutures is considered a "clean" technique. The skin is well healed by this time. However, DO NOT take all of them out if the edges start to separate. You may only take out every other one. You NEED TO USE GOOD JUDGEMENT on this, and let the surgeon know.
