Novel bacterial immobilization compound effectively decreases bacterial counts in healthy volunteers

Skin flora immobilization technology is similar in efficacy to Iodine-Povidone in healthy volunteers. We did a prospective study in a university clinic with 60 healthy volunteers. Right inguinal skin area on healthy volunteers was used to compare the antimicrobial properties of cyanoacrylate sealant (FloraSeal, Adhesion Biomedical, Wyomissing, PA) versus standard surgical preparation Povidone-iodine (Betadine, Purdue Productions, Stamford, CT). Bacterial counts were measured at different time intervals: 15 minutes, 4 hours, and 24 hours. Bacterial colony forming units were compared between Povidone-iodine and cyanoacrylate sealant. The absolute log reduction was 5.568 for Povidone-iodine (7 absolute CFU); 5.028 for cyanoacrylate (59 absolute CFU); and 5.568 for Povidone-iodine and cyanoacrylate combined (21 absolute CFU). Cyanoacrylate was able to sustain a reduction on bacterial counts at 4 hours and 24 hours of more than 99.8 per cent as compared with the control group. Cyanoacrylate microbial sealant successfully reduces bacterial counts on normal healthy skin. The results were similar to Povidone-iodine alone. We believe this technology may be an excellent means of mitigating incisional surgical site infection by reducing the risk of contamination by skin flora and warrants further testing.
