Hot air from the Ohio Statehouse, they sure generate enough in Columbus! Seriously I think they inflated and then pumped it out at the end. Weird, when I got to my patient room, I expected to be FATTENED UP, I was not. I expected ABD and such, nope 4 criss cross steristrips , 1 in top of navel, 1 lengthwise steriStrip 7/8 inch,long on right, Big Red the main one, RNY are on the right, sleevers on the left because that is where they pull the stomach remnant out. Anyway he had 5 up and down steri-strips on him. And 1 little one at the bottom of my sternum. But all small critters. Hardly any swelling/bruising on them.Barely slashed, barely gashed and no signs of bashed. My guy does quality work!
