Limits to progressive reduction of resident skin bacteria by disinfection.
Antiseptic preparations used repeatedly to disinfect the skin caused a reduction in yield of resident flora to a low equilibrium level beyond which further reduction did not occur. This equilibrium varied with the antiseptic preparation used. In a comparison of three preparations, the lowest equilibrium level was obtained with 95% ethyl alcohol. The further reduction in yield of skin bacteria o...

Contamination of blood cultures is believed to occur mainly during the venepuncture procedure. Consequently, meticulous preparation of the venepuncture site is widely recommended. To determine whether the contamination rate is indeed affected by the quality of the antiseptic procedure at the venepuncture site, 181 paired cultures were collected from 176 patients during a 6-month period after ei...
متن کاملDisinfection of needleless catheter connectors and access ports with alcohol may not prevent microbial entry: the promise of a novel antiseptic-barrier cap.
BACKGROUND Needleless valve connectors for vascular catheters are widely used throughout the United States because they reduce the risk of biohazardous injuries from needlesticks and exposure to bloodborne pathogens, such as human immunodeficiency virus and hepatitis C virus. Patients with long-term central venous catheters are at significant risk of acquiring catheter-related bloodstream infec...
متن کاملMethods for Disinfection of Hands and Operation Sites.
In previous studies we compared the relative value of alternative methods for disinfecting the hands of nurses and surgeons and the skin of operation sites, but a number of relevant questions were not considered. For disinfection of the operation site alcoholic solutions of chlorhexidine (0.5%) and iodine (1%) were found to be equally effective and superior to a number of other agents (Lowbury,...
