Hi Mike,
Had to bridge twice since my surgeries. Should be no issues for you, other than having to inject yourself twice a day while bridging.
When you come off it, as you go back to building up your INR on your Warfarin, you may want to monitor it more frequently, if you home test, no big deal, otherwise, your doctor and lab should be on top of it with you.
Also, if you do home test, there are some units that do not give correct readings with Lovenox. I believe that the only home testing unit that does is Coaguchek. You should do a search on the site, there were many posts in the past regarding this.
The Lovenox will cause minor bruising in the area of the injections. Just be sure to pinch an inch in the proper area, and inject in the fold of the pinch. Keep in mind that you will be injecting in the same general area, so map out your injection pattern in your mind prior to beginning, I think this made it easier for myself.
Good luck, and as I mentioned, it was no big deal for me, other than having to inject myself,(don't like needles-what can I say,)
