After patient positioning and prior to skin preparation an extra surgical time-out and site identification will be performed. The preparation of the skin will then be conducted according to the manufacturer's specifications for each skin preparation solution. After skin preparation, the solution will be allowed to dry while the patient is draped. Prior to applying the impermeable drape to the skin, digital photographs will be taken. Specimens will be photographed using a digital still camera (Digital Rebel XTi, Canon U.S.A., Lake Success, NY) with a 100-mm macro lens (EF 100mm f/2.8 USM Macro Lens, Canon U.S.A.), and ring flash (MR-14EX TTL, Canon U.S.A). The camera captures data at 10.1 megapixels and will be set in RAW mode. The shutter speed will be set at 1/60s with an F-stop value of 4.0. The camera was placed at a fixed distance from the skin using a tripod. After photography the impervious drape will be placed and another surgical time-out will be performed. The surgeon, anesthesiologist and nurse must all agree on the surgical site and it must be confirmed with the consent form, the patient records and the radiographs.
