Mortality and morbidity of nosocomial respiratory syncytial virus (RSV) infection in ventilated children--a ten year perspective.
Respiratory syncytial virus (RSV) is one of the most common pathogens involved in nosocomial infection in children. The aim of the study was to determine the impact of nosocomial RSV infection on mortality and pediatric intensive care unit (PICU) morbidity of ventilated children. ⋯ Nosocomial RSV infection was independently associated with increased mortality and was the strongest predictor of duration of ventilation and length of stay in children on PICU. Decreasing nosocomial RSV infection would reduce deaths in ventilated children.

Randomized Controlled TrialPositive end-expiratory pressure following coronary artery bypass grafting.
Cardiac surgery-related pulmonary complications include alterations in lung mechanics and anomalies in gas exchange. Higher levels of positive end-expiratory pressure (PEEP) have been suggested to benefit cardiac surgical patients. We compared respiratory compliance, arterial oxygenation and time till tracheal extubation in 2 cohorts of patients weaned from mechanical ventilation with different levels of PEEP after elective and uncomplicated coronary artery bypass grafting (CABG). We hypothesized that higher PEEP levels improve pulmonary compliance and gas exchange in the first hours of weaning from mechanical ventilation, but not to shorten time till tracheal extubation. ⋯ Use of higher PEEP levels after elective uncomplicated CABG improves pulmonary compliance and oxygenation but seems to be associated with a delay in tracheal extubation.

ReviewProcalcitonin and sepsis: recent data on diagnostic utility prognostic potential and therapeutic implications in critically ill patients.
Procalcitonin (PCT) has emerged as the most specific biomarker for bacterial infection. As clinicians become more familiar with its use, a multitude of observational studies have reported on its diagnostic potential in distinct types of infections and various clinical situations, such as in neutropenia or in the postoperative period. In the Intensive Care Unit setting, however, the prognostic value of a single PCT measurement at the time of admission on a patient with sepsis is suboptimal. ⋯ The most recent significant development in the field of PCT monitoring, is the publication of several randomized controlled trials that investigated its use as a decision making tool for the initiation and/or the duration of antibiotic treatment. Currently, the available evidence suggests that the incorporation of PCT measurements to assist with the duration of antibiotic stewardship programs may decrease antibiotic use without compromising clinical outcomes. Nevertheless, this strategy still needs further validation in large prospective studies.
