Health care-associated infections (HAIs) result in increased patient morbidity and utilization of health care resources. Rates of HAI are increasing despite advances in health care technology. Limited antimicrobial agents and a dry drug pipeline make novel prevention efforts critical. Chlorhexidine, an antiseptic solution that has been used worldwide since the 1950s, is a safe and effective pro...

Antiseptic solutions are used to reduce the levels of pathogenic microorganisms on the skin prior to surgical interventions. Chlorhexidine is widely used for such purposes, as it is active against both gram-negative bacteria and yeast, but in particular against gram-positive bacteria. Chlorhexidine allergy, either immediate type I (1) or as delayed type IV allergic contact dermatitis reactions,...

BACKGROUND Protection of the catheter site by antimicrobial agents is one of the most important factors in the prevention of infection. Povidone iodine and chlorhexidine gluconate are the most common used agents for dressing. The purpose of this study was to compare the effects of povidone iodine, chlorhexidine gluconate and octenidine hydrochloride in preventing catheter related infections. ...

We modelled a 'clean' surgical wound lightly contaminated with airborne bacteria, using agar, ovine muscle and ovine adipose tissue. This was used to assess the effect on bacteria of ultraviolet C light (UVC) 1200 mu W/cm2, hydrogen peroxide 3%, povidone-iodine 1% and 10%, chlorhexidine 0.05%, pulsed jet lavage with UVC and syringe and needle lavage with chlorhexidine 0.05%. All the agents were...

Background: Antiseptic scrub and paint can reduce bacterial colonization and postoperative wound infection. Two forms of antiseptics, povidone iodine and chlorhexidine, are commonly used in the operating theater. Objective: To study the efficacy of the reduction of bacterial colonization and surgical wound infection among these antiseptic. Material and Method: Five hundred surgical patients wer...

Six patients in the neurosurgical ward of Fukushima Medical College Hospital suffering from ventriculitis due to Achromobacter xylosoxidans infection had undergone craniotomy or cranial trepanation before the infection. The strains of A. xylosoxidans isolated from the patients were resistant to streptomycin, ampicillin, cephaloridine, gentamicin, and colistin. They were also resistant to chlorh...

Skin antisepsis prior to the induction of spinal anesthesia is essential because of the potential for infectious complications. Povidone-iodine is a widely used antiseptic solution for skin preparation before spinal anesthesia, and chlorhexidine alcohol solution is a commonly used alternative to povidone-iodine. Previous studies have shown that chlorhexidine is more effective than povidone-iodi...
