nasal rinse and respiratory tract infection

PURPOSE: Methicillin-resistant Staphylococcus aureus (MRSA) decolonization is a widely established, though controversial part of many MRSA controlling strategies. The aim of this study was to evaluate our decolonization success rate, identify the risk factors for decolonization failure and determine the optimal duration of follow-up in our low MRSA prevalence setting (2.6 % of isolates). METHODS: Every patient with newly detected MRSA colonization or infection between January 2007 and December 2009 was recruited to the study...

OBJECTIVE: To determine the efficacy ofperioperative decontamination of the nasopharynx and oropharynx in reducing nosocomial infection after cardiac surgery with the use of 0.12% chlorhexidine. DESIGN: Randomized, double-blind, placebo-controlled clinical trial (www.clinicaltrials.gov; identifier NCT00272675). METHODS: The trial was conducted at the Onze Lieve Vrouwe Gasthuis, Amsterdam, the Netherlands, from 1 August 2003-31 August 2005...

CONTEXT: Nosocomial infections are an important cause of morbidity and mortality after cardiac surgery. Decolonization of endogenous potential pathogenic microorganisms is important in the prevention of nosocomial infections. OBJECTIVE: To determine the efficacy of perioperative decontamination of the nasopharynx and oropharynx with 0.12% chlorhexidine gluconate for reduction of nosocomial infection after cardiac surgery. DESIGN, SETTING, AND PARTICIPANTS: A prospective, randomized, double-blind, placebo-controlled clinical trial conducted at the Onze Lieve Vrouwe Gasthuis, Amsterdam, the Netherlands, between August 1, 2003, and September 1, 2005...

Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis...
