Reproducibility of cerebral oxygenation measurement in neonates and infants in the clinical setting using the NIRO 300 oximeter.
To study reproducibility of cerebral tissue oxygenation index (cTOI) values in neonates and infants in a clinical setting using the NIRO 300 oximeter (Hamamatsu Photonics, Hamamatsu City, Japan). ⋯ The present study shows that cTOI measurements using the NIRO 300 oximeter at the lateral forehead of neonates and infants are not well reproducible under clinical conditions. This raises the question whether generally valid normal values can be defined with the used approach and makes it difficult to determine a normal range of cerebral oxygenation.

To define urinary tract infections in critically ill children in the intensive care unit setting for the purpose of surveillance of infection, enrollment of children in sepsis trials, and for trials of therapy and prevention. ⋯ Definitions for definite, probable, and possible urinary tract infection were achieved by consensus that can be used for surveillance and enrolment in sepsis trials. Future research should determine the utility of these definitions in the critically ill child and adapt them accordingly.

Nurse staffing and unplanned extubation in the pediatric intensive care unit.
To determine the association between unplanned extubations and years of nurse experience and nurse-to-patient ratio in the pediatric intensive care unit (PICU). ⋯ Pediatric patients are more likely to experience an unplanned extubation when being cared for by a nurse assigned to two patients compared with a nurse caring for one patient. To provide safe patient care, health care policymakers and hospital administrators should consider the nurse-to-patient ratio and its potential association with adverse events in hospitalized children.

A retrospective cohort study of prognostic factors associated with outcome in pediatric severe sepsis: what is the role of steroids?
Systemic corticosteroids remain controversial in the treatment of pediatric patients with severe sepsis. Recent studies in septic adults have shown decreased mortality with the use of hydrocortisone in patients with relative adrenal insufficiency. We conducted this large retrospective cohort study to further characterize severe sepsis in infants and children and correlates of outcome, including the use of steroids. ⋯ From this administrative database analysis, there is no evidence that steroids are associated with improved outcome in critically ill infants and children with sepsis. Although steroids may be given preferentially to more severely ill children, their use was associated with increased mortality. Clinicians should maintain equipoise on this topic pending prospective randomized clinical trials.

The strong ion gap predicts mortality in children following cardiopulmonary bypass surgery.
Stewart's strong ion theory quantifies unmeasured tissue acids produced following hypoxia or hypoperfusion, by calculation of the strong ion gap. Our study objectives were as follows: a) to determine the 24-hr profile of the strong ion gap following cardiopulmonary bypass surgery; and b) to compare the prognostic value in terms of intensive care unit mortality of this variable with blood lactate. ⋯ An elevated strong ion gap occurs commonly following bypass surgery and appears to be superior to lactate as a mortality predictor.
