ReviewAntiseptic Irrigation as an Effective Interventional Strategy for Reducing the Risk of Surgical Site Infections.
A surgical site infection (SSI) can occur at several anatomic sites related to a surgical procedure: Superficial or deep incisional or organ/space. The SSIs are the leading cause of health-care-associated infection (HAI) in industrialized Western nations. Patients in whom an SSI develops require longer hospitalization, incur significantly greater treatment costs and reduction in quality of life, and after selective surgical procedures experience higher mortality rates. ⋯ In an era of antibiotic stewardship, with a widespread prevalence of bacterial resistance to multiple antibiotic agents, there has emerged an interest in using intra-operative antiseptic irrigation to reduce microbial contamination in the surgical site before closure and possibly reduce the need for antibiotic agents. This approach has gained added appeal in an era of biomedical device implantation, especially with the recognition that most, if not all, device-related infections are associated with biofilm formation. This review focuses on the limited, evidence-based rationale for the use of antiseptic agents as an effective risk reduction strategy for prevention of SSIs.

Incisional Negative Pressure Wound Therapy for Surgical Site Infection Prophylaxis in the Post-Antibiotic Era.
Background: With the prospect of antibiotic failure in the post-antibiotic era, strategies that prevent surgical site infection (SSI) are increasingly important. Current literature suggests that incisional Negative Pressure Wound Therapy (iNWPT) is a promising intervention. Methods: Based on published literature regarding iNPWT, its mechanisms of action, and clinical results, a narrative summary was built, including both the experimental as well as the clinical literature. Results: The experimental literature indicates that iNPWT provides a barrier against external contamination before re-epithelialization, increases blood flow and lymphatic clearance, and reduces edema. Meta-analyses of randomized studies indicate that iNWPT is effective in reducing SSI. ⋯ For now, iNPWT is recommended for incorporation in SSI prevention bundles. The iNPWT as a substitute for antibiotic prophylaxis is not recommended currently. Further reduction of SSI by iNPWT will lessen the need for therapeutic use of antibiotic agents.

Keeping it Simple: Impact of a Restrictive Antibiotic Policy for Ventilator-Associated Pneumonia in Trauma Patients on Incidence and Sensitivities of Causative Pathogens.
An integral part of ventilator-associated pneumonia (VAP) therapy is the appropriate choice of empiric antibiotics. Our previous experience demonstrated adherence to an empiric therapy pathway was associated with only modest changes in organisms causing VAP. The purpose of the current study was to evaluate the impact of a restrictive antibiotic policy for VAP in trauma patients on the incidence and sensitivities of causative pathogens since the previous study. ⋯ A comprehensive protocol for the diagnosis and management of VAP, along with antibiotic stewardship, can prevent the development of bacterial resistance to empiric therapy.

Observational StudyDoes Wound Irrigation with Clorhexidine Gluconate Reduce the Surgical Site Infection Rate in Closure of Temporary Loop Ileostomy? A Prospective Clinical Study.
The aim of this study was to investigate the effect of irrigating the surgical site with 0.05% chlorhexidine gluconate (CHG) on surgical site infection (SSI) in temporary loop ileostomy closure. ⋯ Irrigation of the incision with 0.05% CHG reduces the SSI rate compared with saline irrigation. There is a need for randomized and wider trials to clarify the effect and standards of incision irrigation.

Randomized Controlled TrialEvaluating the Duration of Prophylactic Post-Operative Antibiotic Agents after Open Reduction Internal Fixation for Closed Fractures.
The importance of timely pre-operative antibiotic agents for effective surgical prophylaxis has been established but the optimal duration of antimicrobial coverage post-operatively has not yet been defined clearly. The purpose of this study was to determine if prophylactic post- operative cefazolin for 23 hours decreases the risk of surgical site infection (SSI) after open reduction internal fixation (ORIF) of closed extremity fractures. ⋯ Although not statistically significant, in a randomized double-blinded placebo-controlled trial, patients who were treated with a 23-hour post-operative regimen of antibiotics after ORIF were less likely to develop SSIs. Patients with diabetes mellitus and those with a risk score of two or greater were more likely to develop an SSI.
