Prediction of raised intracranial pressure complicating severe traumatic brain injury in children: implications for trial design.
To describe current patterns of management of raised intracranial pressure (ICP) in traumatic brain injury relevant to clinician buy-in to possible randomized controlled trials of treatments of raised ICP. To examine the feasibility of early identification of children at sufficient risk of developing raised ICP to permit a uniform approach between centers to the initiation of ICP monitoring. This would permit quantification of ICP elevation and enrollment as appropriate to randomized controlled trials of raised ICP interventions. ⋯ Simple models based on early clinical data may predict the development of raised ICP sufficiently well to encourage a consistent approach between centers to initiation of ICP monitoring. We estimate studies designed to detect reductions in ICU mortality will require >320 children per arm, although this figure may be higher if more conservative assumptions are made.

Energy expenditure and caloric and protein intake in infants following the Norwood procedure.
Cardiopulmonary bypass in infants results in a hypermetabolic response. Energy requirements of these patients have not been well studied. We assessed energy expenditure and caloric and protein intake during the first 3 days following the Norwood procedure. ⋯ Infants exhibit a hypermetabolic response immediately following the Norwood procedure. Caloric and protein intake was inadequate to meet energy expenditure during the first 2 days after surgery. Further studies are warranted to examine the effects of caloric and protein supplementation on postoperative outcomes in infants after cardiopulmonary bypass.

Correlation of abdominal site near-infrared spectroscopy with gastric tonometry in infants following surgery for congenital heart disease.
Splanchnic oximetry, as measured by near-infrared spectroscopy (NIRS), correlates with gastric tonometry as a means of assessing regional (splanchnic) oxygenation and perfusion. ⋯ Abdominal site rSO2, measured in infants with either single or biventricular physiology, exhibits a strong correlation with gastric pHi as well as with serum lactate and SVO2. The results indicate that rSO2 measurements over the anterior abdominal wall correlate more strongly than flank rSO2 with regard to systemic indices of oxygenation and perfusion. This study suggests that the NIRS monitor is a valid modality to obtain an easy, immediate, and noninvasive measurement of splanchnic rSO2 in infants following cardiac surgery for congenital heart disease.

Parents' perspectives on physician-parent communication near the time of a child's death in the pediatric intensive care unit.
Communicating bad news about a child's illness is a difficult task commonly faced by intensive care physicians. Greater understanding of parents' scope of experiences with bad news during their child's hospitalization will help physicians communicate more effectively. Our objective is to describe parents' perceptions of their conversations with physicians regarding their child's terminal illness and death in the pediatric intensive care unit (PICU). ⋯ The way bad news is discussed by physicians is extremely important to most parents. Parents want physicians to be accessible and to provide honest and complete information with a caring affect, using lay language, and at a pace in accordance with their ability to comprehend. Withholding prognostic information from parents often leads to false hopes and feelings of anger, betrayal, and distrust. Future research is needed to investigate whether the way bad news is discussed influences psychological adjustment and family functioning among bereaved parents.

Do outcomes vary according to the source of admission to the pediatric intensive care unit?
To examine associations between mortality, length of stay, and the sources of admission to tertiary pediatric intensive care. ⋯ Outcomes of tertiary pediatric intensive care vary significantly by source of admission. Strategies aimed at reduction of mortality at the tertiary PICU should target transfer admissions from the hospital's wards and from PICUs of other hospitals.
