Pete:<br><br>I went through my old course material but was unable to find the specific info (Its been about 12 years).<br><br>As I recall, the study was performed because a patient had blood drawn and the resulting analysis indicated alcohol in the bloodstream. It was then determined that the patient had not consumed any alcohol for an extended period prior to the draw.<br><br>The hypothesis that was tested and subsequently proven was that the the cathether had been contaminated with the isopropyl alcohol during insertion. This, in turn, caused the incorrect results<br><br>I believe, but I am not 100% sure, that the original patient took legal action against the involved hospital because of the erroneous results.<br><br>I remember this study because I was part way through my EMT-I training when our hospital suddenly mandated the use of Betadine for all IV starts.<br><br>
