The increasing prevalence of MDR P. aeruginosa in ICU patients has rekindled interest in polymyxins, which had been abandoned because of toxic side effects. Colistin retained significant in vitro activity against this virulent organism, had an acceptable safety profile, and should be considered as a treatment option in critically ill patients with infection caused by MDR gram-negative bacilli. Aerosolized colistin may merit further consideration as a therapeutic intervention for patients with refractory pulmonary infections.
Peer reviewed article he aim of the present survey was to evaluate nurses' knowledge regarding sepsis in Greece. A total of 835 registered nurses (125 males/710 females) from tertiary hospitals in Greece were interviewed from April 2008 to December 2009. All participants completed a selfcompleted questionnaire about assessment of sepsis (see Figure 1). Basic demographic information was recorded. The protocol and questionnaire were approved by the Ethics Committees of participating hospitals. The majority of the participants answered correctly regarding awareness of systemic inflammation -83.5% regarding the role of temperature in the definition of systemic inflammation; 81.3% regarding the importance of white blood cell count; and 49.9% and 46.3% regarding the role of tachycardia and tachypnoea, respectively. The same pattern was observed regarding the answers about the assessment of sepsis -79.4% of the nurses answered correctly about the role of blood pressure; 70.9% about the role of urine volume; and 43.5% about the importance of oxygen saturation. Finally, 57.2% of the participants confirmed that in practice they followed the current guidelines for the diagnosis and treatment of patients with sepsis. The study has established baseline data with which future studies can be compared.
The prompt determination, isolation and appropriate treatment of MRSA patients admitted from other institutions combined with the detection and elimination of carriers among new health care workers and patients at high risk of developing infectious complications prevented further spread of the pathogen.
The increasing prevalence of multidrug-resistant A. baumannii in surgical intensive care unit patients creates demand on strict screening and contact precautions. Following this infection control strategy we were able to achieve intermittent eradication of the pathogen during a 16-month period with continuous function of the intensive care unit. Despite the significant in vitro activity of colistin against multidrug-resistant Acinetobacter baumannii the results were discouraging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
