Evaluation of the efficacy of antibacterial medical gloves in the ICU setting.

BACKGROUND: Inappropriate use of medical gloves may support microbial transmission. New strategies could increase the safety of medical gloves without the risk of patient and surface contamination. AIM: To compare the efficacy of synthetic antibacterial nitrile medical gloves coated with polyhexamethylen-biguanid hydrochloride (PHMB) on the external surface with identical non-antibacterial medical gloves in reducing glove contamination after common patient care measures in an intensive care unit (ICU) setting. METHODS: ICU staff wore either standard or antibacterial gloves during patient care activities. The number of bacteria on gloves was measured semi-quantitatively immediately after the performance of four clinical activities. FINDINGS: There was a significant difference in mean bacterial growth [colony-forming units (cfu)] between control gloves and antibacterial gloves {60 [standard deviation (SD) 23] vs 16 (SD 23) cfu/glove imprint, P < 0.001}. In three of the four clinical activities (intravenous fluid handling, oral toilet and physiotherapy), the antibacterial gloves had significantly less bacterial contamination compared with the control gloves (P = 0.011 and <0.001, respectively). Although antibacterial gloves showed lower bacterial contamination after changing linen compared with control gloves, the difference was not significant (P = 0.311). CONCLUSION: This study showed that use of antibacterial medical gloves significantly reduced bacterial contamination after typical patient care activities in 57% of the investigated clinical activities (P < 0.01). The use of antibacterial medical gloves may support reduction of cross-contamination in the ICU setting.

Fatal influenza A (H3N2) and Campylobacter jejuni coinfection.

The rapid diagnosis and subtyping of influenza is particularly important in areas where avian influenza (H5N1) is present. The ability to recognise both typical and atypical presentations of influenza is also critical in such settings. A six-month-old male child who visited a H5N1-affected area subsequently died from a severe febrile diarrhoeal illness with minimal respiratory symptoms, and was initially diagnosed with influenza A of an unknown subtype. The final microbiological results showed a highly unusual combination of influenza A (H3N2) and Campylobacter jejuni infection.
