Lack of correlation between left ventricular outflow tract velocity time integral and stroke volume index in mechanically ventilated patients.
To assess the correlation between left ventricular outflow tract velocity time integral (LVOT VTI) and stroke volume index (SVI) calculated by thermodilution methods in ventilated critically ill patients. ⋯ LVOT VTI could be a complementary hemodynamic evaluation in selected patients, but does not eliminate the need for invasive monitoring at the present time. The weak correlation between LVOT VTI and invasive monitoring deserves additional assessment to identify the factors affecting this disagreement.

Catheter-related urinary tract infections are very common both in the community and in the acute hospital care setting, particularly in the critical care environment. In order to minimize this problem, it is essential to adopt a correct approach from insertion to withdrawal of the urinary catheter, and always perform proper antisepsis. ⋯ The entire process is complemented with considerations on how to secure proper management of the indwelling urinary catheter.

Hygiene and skin care of patients admitted to the Intensive Care Unit (ICU) are part of basic care. For some years there has been evidence of skin colonization by multiresistant gramnegative and grampositive pathogens. ⋯ This article reviews the current situation of this strategy, as well as the positioning of the authors in relation to the spreading of its use in ICUs.

Several measures related to asepsis for preventing catheter-related bloodstream infection have been proposed. The aseptic measures recommended by scientific societies include hand hygiene of the person who is inserting or manipulating the catheter; maximum sterile barrier precautions during catheter insertion; disinfection of catheter hubs; the use of needle-less connectors and injection ports; the avoidance of antibiotic ointments (except in hemodialysis catheters); change the dressing if it is soiled, loose or damp; and aseptic technique during dressing changes. Other measures only recommended by the most recently published guides (possibly due to the publication of recent studies reporting their beneficial effects) are the use of antimicrobial-impregnated dressings, changing transparent dressings every 7 days, and bathing of the patient with chlorhexidine.

Needleless connectors provide easy access points to the vascular system for the administration of fluids, avoiding the risk of accidental punctures and increasing safety in vascular access manipulation. Non-aseptic manipulation can favor contamination, turning connectors into the penetration route for endoluminal contaminants with the capacity of triggering infectious complications, with serious consequences for the patient. ⋯ Monitoring adherence to safe practices and reporting results are important to promote understanding of the risks and benefits of decontaminating connections and thus to improve patient safety. safety.
