This past weekend, Kevin MD, told us about Sharpie’s actually being anti-bacterial.
Surgeons use markers to identify the right body part for procedures. Unfortunately, they care become contaminated with bacteria which can lead to surgical site infections.
Enter the Sharpie: "As it turns out, the ink used in a Sharpie pen has an alcohol base, making it an unexpected germ fighter." ….
That’s nice to know, but mostly what I got from the report was the reminder to clean the tips of the reusable markers with an alcohol based wipe between patients. For me the marker helps me in my planning, not in my germ control. Here is my post on marking/markers from last December.
Marking is very important in both my quilting and my surgery work. I don't mean the kind of marking that gives you "yellow snow" (nod to Frank Zappa) or the kind that leaves you a trail of crumbs to find your way home (Hansel and Gretel).
In plastic surgery, a lot of time can be spent in the preop area marking your patient. So you want a marker that won't wash off so easily that it is gone with the scrub. For breast and body "work", I use (and the nurses tell me so do most of the others) a black Sharpie.
It is marketed as a permanent marker, but I still find that I have to remind the person prepping the patient to not "scrub too hard" or "that's enough". When you have marked the patient standing or bending in different ways to be sure you get the most skin removed, these positions and maneuvers can't be duplicated in the operating room. During the procedure, I use whatever marker the hospital has, usually the Accu-line products. Those are also what I use when I need a really fine line (ie eyelid) when marking.
The skin marker should be nontoxic and non-allergenic. If used during the procedure, then it must be sterilizable. The ink must have a visible color and must be non-reactant with other chemicals used on the skin (e.g., povidone iodine). The ink must be resistant to mechanical cleaning but removable in time. The information immediately below is from the first reference article.
The photo to the right is from the first article referenced below. Note how the ink "disappears" with the scrub. Their skin marking ink (1) and frequently used skin markers (2, methylene blue dye; 3, Securline, a surgical skin marker; 4, red permanent marker; 5, black permanent marker; and 6, Viscot, a surgical skin marker). (Center) Skin prepared with povidone iodine solution and scrubbed five times. (Below) Skin prepared with Betadine and scrubbed five times. Their marking ink --The formula consists of basic fuchsin (1.3 g of dye material), 5.6 ml of acetone (resolvent), 11 ml of alcohol (dissolvent), and 100 ml of distilled water. This formula may be diluted by adding alcohol.
In quilting, you want a marker that will stay long enough to see the pattern you are quilting. You want to be able to either "brush" it off gently later (as with chalk pencils) or to wash it out. The different colors of fabrics used can sometimes make this more challenging. For the quilt I am preparing for hand quilting, I used the blue washable marker on the "mustard" (light fabric) and a silver chalk pen on the brown (dark fabric). Here are some links to tips by experts like Ami Simms (blue washable marker), and Sharon Darling (Quilter's Choice Marking Pencil, Miracle Chalk).
