d program ) samples tested : effect of application to hands of pvpi waterless surgical prep spray verses traditional hand scrub with betadine surgical scrub and water . these represent colony forming units post swab after wearing gloves for 60 minutes . gloves were applied at 5 minutes after completing the surgical scrub . this is an indication of duration of effect verses traditional standard methods used today . appears to be that as long as the waterless pvpi is coating the hand there is a positive effect of reducing skin bacteria . the product has been shown to persist experimentally for over 12 hours without losing integrity when covered by a surgical glove . it offers an effective barrier to bacterial contamination in the event of glove failure . it also provides a similar effect on reducing contamination from the skin around and in a wound environment which experimentally will last up to 24 hours after a single application . it can be washed off with water with moderate physical action . once dried it is resistant to moisture and will not wash off readily with a stream of water or the action of bleeding . it provides an effective long term physical and chemical barrier to re - colonization of the skin following application unlike traditional methods of scrubbing or water based antibacterial formulations . it also prevents the need to physically interact with the wound or skin around a surgical site reducing the potential for additional physical microbiological cross contamination . this same effect can be applied to inanimate objects also . it can be sprayed on instruments and allowed to dry to provide a bacteria free environment in a field setting and to reduce the potential for recontamination if working in contaminated wound setting study of barrier ® on mortality rate after castration and tail docking an initial study was completed in february 2011 on piglets looking at the effect barrier ® has on castration and tail docking in the farrowing crate . a summary of what we found verses controls are : 1 . reduced bleeding in the barrier ii treated piglets five minutes post application following the completion of the study , the study site has continued to purchase and use barrier ii routinely for castration and tail docking and their pig champ records are showing a marked reduction in preweaning mortality in day 8 and older piglets in the magnitude of five additional full value piglets at weaning per thousand pigs treated with barrier ii . most of this benefit related to less laid on piglets after 8 days of age most likely due to the reduction in post surgical infection rates that we saw in our initial study . see the chart in fig1 showing the percent of preweaning mortality by age with trend lines and total preweaning mortality for this farm . barrier with pain relief started being used the second week of february 2011 . prior to using barrier , this farm was routinely using 0 . 5 percent tincture of iodine . we believe based on this data , barrier ii — povidone iodine wound spray with pain relief — is a good way to lower preweaning mortality and address the needs of the piglet following these routine surgical procedures . barrier ® treatment and non - treatment groups were the same quality prior to treatment 34 % improved activity in treated piglets over 60 minutes 32 % reduced bleeding over 60 minutes 26 % reduced in average inflammation over 72 hour period 23 % reduction in abscessation over 72 hour period while the invention has been described with reference to certain exemplary embodiments thereof , those skilled in the art may make various modifications to the described embodiments of the invention without departing from the scope of the invention . the terms and descriptions used herein are set forth by way of illustration only and are not meant as limitations . in particular , although the present invention has been described by way of examples , a variety of compositions and methods would practice the inventive concepts described herein . although the invention has been described and disclosed in various terms and certain embodiments , the scope of the invention is not intended to be , nor should it be deemed to be , limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved , especially as they fall within the breadth and scope of the claims here appended . those skilled in the art will recognize that these and other variations are possible within the scope of the invention as defined in the following claims and their equivalents .
