Preoperative skin preparation with antimicrobial agents decreases the risk of surgical site infection, but concerns have been raised about the visibility of a common surgical preparatory agent (ChloraPrep; Becton, Dickinson & Co, Franklin Lakes, New Jersey), depending on skin pigmentation. Poor visibility may lead to failure to identify inadequately prepared skin, increasing the risk of surgical site infection. This study was conducted to determine whether different tints of ChloraPrep and different skin pigmentations affect the ability of orthopedic surgeons to identify the adequacy of skin preparation...

BACKGROUND: Intra-operative surgical site irrigation (lavage) is common practice in surgical procedures in general, with all disciplines advocating some form of irrigation before incision closure. This practice, however, has been neither standardized nor is there compelling evidence that it effectively reduces the risk of surgical site infection (SSI). This narrative review addresses the laboratory and clinical evidence that is available to support the practice of irrigation of the abdominal cavity and superficial/deep incisional tissues, using specific irrigation solutions at the end of an operative procedure to reduce the microbial burden at wound closure...

BACKGROUND: Chlorhexidine skin preparation has been shown to provide highly effective antimicrobial presurgical skin cleansing. However, there is a significant risk of ocular toxicity when it is used in periocular areas. CASE DESCRIPTION: We describe 2 cases of significant corneal damage resulting from 4% chlorhexidine gluconate preoperative skin cleanser, despite the use of protective occlusive dressing over the eyes. Because of the potential for severe corneal toxicity resulting from use of chlorhexidine, alternative agents such as 10% povidone-iodine should be considered for skin preparation near periocular areas whenever possible...

The success of endodontic treatment is directly enhanced by elimination of microorganisms in infected root canals. Recently, chitosan, a natural, nontoxic biopolymer, has been introduced as an irrigant that has the capacity to remove the smear layer. The antimicrobial properties of chitosan as an endodontic irrigant have not yet been explored. The purpose of this study was to compare the antimicrobial efficacy of BioPure MTAD, 0.2% chitosan, 1% chitosan, 2% chlorhexidine gluconate, and 3% sodium hypochlorite (NaOCl) against Enterococcus faecalis, which is frequently isolated from persistent root canal infections...
