 The third one is again going to be a little difficult, that is the vertical mattress. I'm just clearing up the way for the vertical mattress. Okay, what I forgot to mention was when you're doing switching, it's taken for granted that you've done the cleaning and draping. It's all mentioned in the last slides, you know, chloro-accidane, isopropyl alcohol, povidone iodine, draping, gloves, you know, putting the gloves like that and all those things. All those things are taken care of. Okay, now we're going to demonstrate, can we flick the next, yes. No, not the running lot, that is vertical mattress. This is again a type of interrupted, but it's a little more complicated. This is done when we want to get very good opposition of the skin, dermis to dermis separately and epidermis to epidermis separately. And this gives a very good scar. Let's say this is our skin institution. First bite, as usual, full thickness, full thickness. Note, far, far, step number one, full thickness, full thickness. As usual, we took a, now watch very carefully. Previously, I had held my needle like this, the usual way I had taught you. Now I'm going to switch the direction of my needle. I'm going to switch the direction of my needle. And I'm holding very close to the tip. Remember, I told you there are certain situations when you do have to hold close to the tip, which is which we're doing now. Because I want to go exactly at the dermo-epidermal junction. That's going to be my next bite, watch carefully. Coffee if you come this side. Yeah, exactly at the dermo-epidermal junction. You can see the tip coming out? At the dermo-epidermal junction. Give it a little push. Again, hold it opposite side, dermo-epidermal junction. Once it cuts through, so I have to take it again. It's repeatedly cutting through. It actually happens also. In actual situation also it keeps cutting through. Because it's a very delicate one at the dermo-epidermal junction. Yes, so first bite was full thickness, full thickness, far, far. Second one was very close, very close, dermo-epidermal, dermo-epidermal. And when I bring it out, now what has happened is both my hands are on the same side. And now I tie it off the usual way. So when I do this, did you notice something? The dermis to dermis has opposed, epidermis has separately opposed to epidermis. I'm going to do it again, don't worry. And then I put a few throws and I close it off. This is called the vertical mattress. This is technically a little more difficult, but it gives very good results. And we finish it off and cut it off. I'll take another one. Now watch carefully. First bite as usual, approximately half a centimeter away. Next one, full thickness. Reverse, hold it close to the tip. Take the dermo-epidermal junction. Take the other side, dermo-epidermal junction. Give it a little push till the apex comes out. You see, automatically the dermis and dermis and epidermis have come together. And then, knot on one side. So you can do this now. You'll find it a little difficult, so you'll have a little more time to do this.
