Comparative Study Clinical TrialComparison of the cerebral effects of dopamine and norepinephrine in severely head-injured patients.
To compare the cerebral effects of dopamine and norepinephrine after severe head injury. ⋯ For the same MAP, ICP was significantly higher with dopamine than norepinephrine with no argument supporting an increase of cerebral blood flow.

In vitro validation of a metabolic monitor for gas exchange measurements in ventilated neonates.
To evaluate the Datex Deltatrac II for measurements in neonates requiring mechanical ventilation. ⋯ Considering limits of agreement of less than +/- 20% as clinically acceptable, results for VO2 assessment indicate acceptable accuracy and precision whereas VCO2 and RQ assessments exceed this limit. Limited accuracy and precision result from detection of CO2 following dilution of expiratory gases and increased sensitivity to error propagation by Haldane equations due to the small differences between inspiratory and expiratory gas fractions.

Comparative StudyInfusion pump performance with vertical displacement: effect of syringe pump and assembly type.
To evaluate the effect of different infusion pump models on continuity of drug delivery during vertical displacement of syringe pumps. ⋯ All tested pumps led to clinically relevant flow irregularities during vertical displacement of the syringe pump. Thus, vertical displacement of any syringe pump connected to an infusion line delivering highly potent drugs at low infusion rates should be avoided. The variability across syringe pumps indicates that syringe pump design remains an area of potential further improvement for reducing the risk of adverse patient events.

Capillary leak syndrome in children who undergo cardiopulmonary bypass: clinical outcome in comparison with complement activation and C1 inhibitor.
Capillary leak syndrome (CLS) is associated with significantly increased morbidity and occurs after cardiopulmonary bypass in children with congenital heart disease. We investigated the early clinical parameters that predict the development of CLS and examined the relationship between the presence of CLS and complement and contact activation and C1 esterase inhibitor (C1-INH) during and after bypass. ⋯ Contact and complement activation occurs during cardiopulmonary bypass and contributes to CLS more frequently in infants of a younger age and with a prolonged bypass time. This activation and decrease in C1-INH was strongly expressed in the CLS group, and therefore early substitution of C1-INH may prevent CLS after open-heart surgery in high-risk infants.
