Evaluation of a 2% chlorhexidine gluconate in 70% isopropyl alcohol skin disinfectant

The efficacy of a new skin disinfectant, 2% (w/v) chlorhexidine gluconate (CHG) in 70% (v/v) isopropyl alcohol (IPA) (ChloraPrep®), was compared with five commonly used skin disinfectants against Staphylococcus epidermidis RP62A in the presence or absence of protein, utilizing quantitative time-kill suspension and carrier tests. All six disinfectants [70% (v/v) IPA, 0.5% (w/v) aqueous CHG, 2% (w/v) aqueous CHG, 0.5% (w/v) CHG in 70% (v/v) IPA and 10% (w/v) aqueous povidone iodine (PI)] achieved a log10 reduction factor of 5, in colony-forming units/mL, in a suspension test (exposure time 30 s) in the presence and absence of 10% human serum. Subsequent challenges of S. epidermidis RP62A in a biofilm (with and without human serum) demonstrated reduced bactericidal activity. Overall, the most effective skin disinfectants tested against S. epidermidis RP62A were 2% (w/v) CHG in 70% IPA and 10% (w/v) PI. These results suggest that enhanced skin antisepsis may be achieved with 2% (w/v) CHG in 70% (v/v) IPA compared with the three commonly used CHG preparations [0.5% (w/v) aqueous CHG, 2% (w/v) aqueous CHG and 0.5% (w/v) CHG in 70% (v/v) IPA]. © 2005 The Hospital Infection Society.

Efficacy of Adding 2% (w/v) Chlorhexidine Gluconate to 70% (v/v) Isopropyl Alcohol for Skin Disinfection Prior to Peripheral Venous Cannulation

We undertook a clinical trial to compare the efficacy of 2% (w/v) chlorhexidine gluconate in 70% (v/v) isopropyl alcohol with the efficacy of 70% (v/v) isopropyl alcohol alone for skin disinfection to prevent peripheral venous catheter colonization and contamination. We found that the addition of 2% chlorhexidine gluconate reduced the number of peripheral venous catheters that were colonized or contaminated. © 2008 by The Society for Healthcare Epidemiology of America.

Le groupe du Fer de Lance mélanésien face à ses défis

Cet article examine la complexité du processus d’intégration régionale en Océanie à travers le cas du groupe du Fer de Lance mélanésien (gflm). L’émergence de cette structure subrégionale en 1988 avait pour but d’affirmer la spécificité mélanésienne au cœur du Pacifique Sud. Or, en vingt-cinq années d’existence, le Fer de Lance ne semble pas avoir pleinement réalisé tous les objectifs qu’il s’était initialement fixés. Ses ambitions, politiques en particulier, ne sont qu’en partie réalisées. Quant à la récente présidence fidjienne du Fer de Lance, elle a tenté de donner une nouvelle stature régionale au groupe, mais y est-elle parvenue ? Cet article analyse les défis politiques, intérieurs et extérieurs, que le gflm rencontre depuis sa création et considère ceux qui lui restent à relever. This paper examines the complexities of regional integration in Oceania through the case study of the Melanesian Spearhead Group (MSG). The emergence of a new subregional structure in 1988 aimed to support the development of the Melanesian identity within the South Pacific. However, after twenty-five years of existence, the Spearhead Group does not seem to have reached all its initial objectives. Its political ambition has only partly been achieved. The recent Fijian leadership of the MSG has attempted to give a new regional dimension to the Melanesian group, but has it succeeded? This paper analyses how the subregional group has faced the challenges that emerged from its regional environment as well as from within its own structure. It fnally considers the new challenges ahead for the Melanesian group.
