I think they are pretty standard (not 100% positive though -- maybe someone else can answer that for you). My drain was only supposed to remain in during my hospital stay and be removed the morning I went home but I had some blood mixed in w/the fluid and my doctor decided it would be safer to leave it in for 1 week. He removed it at his office 1 week post-op. I didn't hurt at all but it sure was gross to look at lol
