It is highly doubtful that the little bit of alcohol on a alcohol pad, prior to starting an IV would cause the blood alcohol to elevate. Most IV start packs in fact have alcohol pads as well as Betadyne to prep a site for an IV. Both have potential uses. Generally alcohol by itself does little to disinfect a site/wound, the contact time to kill various bacteria can be quite long. Generally we use the alcohol pad to remove gross dirt and body oils, the Betadyne is then used to actually disinfect the site. Keep in mind some individuals have iodine allergies (shell fish alleries will give you a clue) and Betadyne should not be used. Beachdoc any thoughts? Pete
