Multicenter Study Comparative StudyParental involvement in treatment decisions regarding their critically ill child: a comparative study of France and Quebec.
To examine whether physicians or parents assume responsibility for treatment decisions for critically ill children and how this relates to subsequent parental experience. A significant controversy has emerged regarding the role of parents, relative to physicians, in relation to treatment decisions for critically ill children. Anglo-American settings have adopted decision-making models where parents are regarded as responsible for such life-support decisions, while in France physicians are commonly considered the decision makers. ⋯ It was remarkable that a certain degree of medical paternalism was unavoidable, regardless of the legal and ethical norms that were in place. This may not necessarily harm parents' moral experiences. Further research is required to examine parental decisional experience in other pediatric settings.

Multicenter Study Comparative StudyContinuous venovenous hemofiltration with or without extracorporeal membrane oxygenation in children.
We report the frequency of usage, patient demographics, and outcomes in children treated with continuous venovenous hemofiltration (CVVH) in three pediatric intensive care units (PICUs), with one unit providing combined extracorporeal membrane oxygenation (ECMO) and CVVH. ⋯ Performing CVVH in a heterogeneous population with large age and weight ranges poses significant clinical and technical challenges. The low frequency of CVVH use, as well as the use of other extracorporeal therapies, also raises problems with maintaining nursing skills. Objective clinical and biochemical markers for commencing CVVH alone or in combination with ECMO remain to be defined.

Multicenter StudyAcute lung injury in pediatric intensive care in Australia and New Zealand: a prospective, multicenter, observational study.
Acute lung injury (ALI) is poorly defined in children. The objective of this prospective study was to clarify the incidence, demographics, management strategies, outcome, and mortality predictors of ALI in children in Australia and New Zealand. ⋯ ALI in children is uncommon but has a high mortality rate. Risk factors for mortality are easily identified. Ventilatory variables and indexes of lung severity were significantly associated with mortality.

Relationship between physiologic deadspace/tidal volume ratio and gas exchange in infants with acute bronchiolitis on invasive mechanical ventilation.
To evaluate the association between deadspace/tidal volume ratio (Vd/Vt) and gas exchange variables: Pao2, Paco2, Pao2/Fio2, arterial/alveolar oxygen tension ratio (Pao2/PAo2), alveolar-arterial oxygen tension difference/arterial oxygen tension ratio (P(A-a)o2/Pao2), carbon dioxide production (Vco2), ventilation index ([Paco2 x peak inspiratory pressure x mechanical respiratory rate]/1000), and oxygenation index ([mean airway pressure x Fio2 x 100]/Pao2), all measured at an early stage in children with obstructive acute respiratory failure. ⋯ In the study population, Vd/Vt not only reflected ventilatory disorders, as is well recognized, but also was associated with disturbances of oxygenation. These results warrant further evaluation of the usefulness of serial measurement of Vd/Vt as a marker of disease severity in severe acute bronchiolitis and other causes of respiratory failure.

To develop a trigger tool for identifying adverse events occurring in critically ill pediatric patients; to identify and characterize adverse events and preventable adverse events experienced by critically ill pediatric patients; and to characterize the patients who experience preventable adverse events. ⋯ Preventable adverse events occurred fairly frequently in the pediatric intensive care unit, but serious harm was rare. Conditions that increased the likelihood of a preventable adverse event were a) need for sedation or pain control; b) relative immobility; and c) need for vascular devices, feeding tubes, or ventilators. Adverse event prevention strategies that focus on improving patient monitoring under increased-risk conditions and improving early detection and treatment of potential harm will likely be more effective than strategies aimed at general error prevention.
