 Everybody, Dr. O. In this video we're going to talk about the bis baguonide, so say that three times fast. So the key one is chlorhexidine and many of you, if you haven't heard of it or don't remember it, you've probably come in contact with it and then we'll talk about a lexidine for just a moment. So the bis baguonides like chlorhexidine, they disrupt cell membranes, which is what makes them so effective. So where would you see these used? The first thing I think of the chlorhexidine is your surgical hand scrubs. So the chemical that's on surgical hand scrubs prior to surgery. But also this would be in the soap that they send home with you prior to surgery. So you're going to be using it on your skin prior to surgery. So I know my dad had open heart surgery to replace an aortic valve and they had him scrubbing up that morning with the chlorhexidine soap. So you've got surgical hand scrubs, you've got surgical soap if you want to call that and then orally as well. So I'm a teeth clencher and I've had to have a couple of oral surgeries because of that. And after these oral surgeries, they give you the chlorhexidine mouthwash, which I love. I always beg the doctor for an extra prescription because I just like how it makes my mouth feel. So this would be chlorhexidine. So again, how it works. It disrupts cell membranes and thinks surgical hand scrubs, some surgical soap. And then oral rinses after oral surgery. So lexidine, maybe you haven't heard of this one, but it will become more common because lexidine can do all the same things. It actually works quicker though. It has to do with its chemical structure. But lexidine is basically a quicker, slightly more effective version of chlorhexidine. But chlorhexidine is still the most important one now. All right. So that is your bispyguanides like chlorhexidine. Hope this helps. Have a wonderful day.
