I had just re-ordered $4000 worth of pain pumps when I first learned about Exparel. After I tried it the first time, I returned all my pain pumps. It's a game changer! When you mix the Exparel with regular marcaine, it gives you both early (nearly immediate) onset of relief of discomfort, as well as 3-4 days of relief afterwards. When I used pain pumps, I never felt the need to inject marcaine into the catheters just prior to removal. There simply wasn't enough discomfort at the time to warrant the injection, with the potential risk of infection (however small).If your surgeon uses progressive tension sutures to do a drainless tummy tuck, there is the risk that the pain pump catheters can get caught on those sutures, making removal of the catheters difficult if not impossible, especially it the surgeon uses barbed sutures as I do. It happened to me.Best thing was getting rid of the painpumps and using Exparel. I think the pain relief is better as well, since the exparel is injected into the abdominal wall, rather than just sitting atop of it, as is the case with the catheters and pain pump. Good luck!
