Effectiveness of gloves in the prevention of hand carriage of vancomycin-resistant enterococcus species by health care workers after patient care.

Gloving reduces acquisition of vancomycin-resistant Enterococcus species (VRE) on the hands, and it should be considered for routine inpatient care, even for contact with the intact skin of patients who may be colonized with VRE. However, gloving does not completely prevent contamination of the hands, and hand washing is necessary after glove removal.

Randomized, blinded, placebo-controlled trial of tissue factor pathway inhibitor in porcine septic shock.

This study tested the hypothesis that tissue factor pathway inhibitor (TFPI) would improve mortality and morbidity evoked by peritonitis-induced bacteremia in pigs. Secondarily, it sought to determine if TFPI treatment would attenuate cardiodynamic abnormalities produced by this septic model. 32 pigs were chronically instrumented with intracardiac transducers to measure left ventricular pressure and diameter, pulmonary and aortic pressures, and cardiac output.

Skin colonization with vancomycin-resistant enterococci among hospitalized patients with bacteremia.

To assess the prevalence of skin and rectal colonization by vancomycin-resistant enterococci (VRE) in hospitalized bacteremic patients and to determine the relation between colonization and bacteremia, we compared 14 case patients who had bacteremia due to VRE with 30 control patients who had bacteremia due to other pathogens. Rectal colonization and skin (inguinal area and/or antecubital fossa) colonization with VRE were common among both case patients (100% had rectal colonization, and 86% had skin colonization) and control patients (37% had rectal colonization and 23% had skin colonization). Among patients with rectal colonization, skin colonization was more common when diarrhea or fecal incontinence was present.

Epidemiology of colonisation of patients and environment with vancomycin-resistant enterococci.

Background: Vancomycin-resistant enterococci (VRE) have emerged as nosocomial pathogens during the past 5 years, but little is known about the epidemiology of VRE. We investigated colonisation of patients and environmental contamination with VRE in an endemic setting to assess the importance of different sources of colonisation.

Methods: Between April 12, and May 29, 1995, cultures from body sites (rectum, groin, arm, oropharynx, trachea, and stomach) and from environmental surfaces (bedrails, drawsheet, blood-pressure cuff, urine containers, and enteral feed) were obtained daily from all newly admitted ventilated patients in our medical intensive-care unit (MICU).

A porcine model of peritonitis and bacteremia simulates human septic shock.

Cardiovascular responses to systemic bacteremia were evaluated in a pre-instrumented, conscious pigs. Basal observations were obtained 5-7 days after instrumentation. On the next day, Escherichia coli 0111.
