Comparative StudyNeutrophil gelatinase-associated lipocalin levels during extracorporeal membrane oxygenation in critically ill children with congenital heart disease: preliminary experience.
To evaluate diagnostic and prognostic significance of neutrophil gelatinase-associated lipocalin during extracorporeal membrane oxygenation in children with congenital heart disease. ⋯ Neutrophil gelatinase-associated lipocalin levels at the first extracorporeal membrane oxygenation day may have predictive value for continuous venovenous hemofiltration. During the course of extracorporeal membrane oxygenation support, creatinine levels were normalized in patients with acute kidney injury undergoing continuous venovenous hemofiltration; in these patients, neutrophil gelatinase-associated lipocalin levels may provide further information on kidney injury.

Comparative StudyThe effect of critical illness and inflammation on midazolam therapy in children.
To determine the effect of inflammation and disease severity on midazolam pharmacokinetics (as surrogate marker of cytochrome 3A activity) and pharmacodynamics in critically ill children. ⋯ Results from this pilot study suggest that increased disease severity is associated with reduced midazolam clearance in critically ill children, most likely as a result of reduced cytochrome 3A activity. In contrast, reduced midazolam clearance does not seem to result in decreased midazolam dose requirements.

Comparative StudyRight-to-left shunting in the ductus arteriosus is induced readily by intense crying and rapid postural change in neonates with meconium-stained amniotic fluid.
To investigate postnatal changes in the direction of blood flow through the ductus arteriosus in neonates with meconium-stained amniotic fluid, we measured preductal and postductal oxygen saturation in normal neonates, neonates with meconium-stained amniotic fluid, and a neonate with persistent pulmonary hypertension of the newborn. ⋯ Right-to-left shunting in the ductus arteriosus may be induced readily by intense crying and rapid postural change in infants with meconium-stained amniotic fluid. It is important to monitor SpO2 at both pre- and postductal regions until 120 mins after birth in neonates with meconium-stained amniotic fluid and to subject these infants to minimal manipulations.

Comparative StudyReliability of the identification of the systemic inflammatory response syndrome in critically ill infants and children.
To assess interobserver reliability of the identification of episodes of the systemic inflammatory response syndrome in critically ill hospitalized infants and children. ⋯ Episodes of systemic inflammatory response syndrome in critically ill infants and children can be identified reproducibly using the consensus definition.

Ultrasound dilution: an accurate means of determining cardiac output in children.
Cardiac output is a useful measure of myocardial performance. Cardiac output monitoring is frequently performed in critically ill adults to guide physicians' treatment strategies. However, standard methods of determining cardiac output in children are not without risk and can be problematic secondary to their invasive nature and other technical problems. The COstatus system (Transonic Systems, NY), which is based on ultrasound dilution technology, works off in situ catheters and uses an innocuous indicator to allow for routine measurements of cardiac output and blood volumes in pediatric patients. The purpose of this study was to validate cardiac output measured by the COstatus system with those obtained by the clinical standard technique of pulmonary artery thermodilution. ⋯ The ultrasound dilution technique of determining cardiac output using the COstatus system provides a less invasive method than the traditional pulmonary artery thermodilution for accurately determining cardiac output in children. This is the first validation of the COstatus system in pediatric patients. Further studies are required to establish its accuracy in pediatric patients with cardiac shunts and other hemodynamically unstable conditions.
