povidone-iodine (PVP-I) a complex produced by reacting iodine with the polymer povidone; it slowly releases iodine and is used as a topical antiinfective agent.
Surgical scrubs are either 2% chlorhexidene gluconate or 7.5% povidone-iodine, although newer alcohol based hand disinfectants are becoming popular. Where I work, they do a regular scrub the first time, and for subsequent cases, go with the alcohol solution. Surgical skin preps used to be a povidone-iodine scrub followed by a povidone-iodine solution (painted on and allowed to dry). There is also an iodine based sticky gel. Occasionally, cholrhexidine is used. Most of the surgeons I work with now use pre-packaged alcohol based prep sponges.
