To determine the incidence of pulmonary fat embolism after the intraosseous (IO) infusion of normal saline and drugs and to determine whether pulmonary capillary blood is a predictor of lung fat embolism. DESIGN: A randomized, prospective, animal study. SETTING: Animal research laboratory of a university hospital. SUBJECTS: Twenty-eight mixed breed piglets (average weight 30.9 kg). Interventions and Methods: Animals were anesthetized, intubated, mechanically ventilated, and instrumented. IO needles were placed in the tibial bone. Animals were assigned to one of four groups: Group 1 received fluid (20 mL/kg) under 300 mm Hg pressure (n = 6); group 2 received fluid (20 mL/kg) at free flow under gravity (n = 6); group 3 received 100 mL of fluid over 20 mins (n = 8); and group 4 received 100 mL of fluid over 7 mins (n = 8). MEASUREMENTS AND MAIN ⋯ Fat embolism is common; however, the method of IO fluid administration does not influence the number of emboli. Our study therefore implies that the risk of fat embolization is of concern, but its clinical relevance is unclear. Until the clinical significance of pulmonary fat emboli and the prevalence of fat emboli syndrome are delineated more precisely, the IO route is an effective but not necessarily safe route for delivery of fluids and drugs.

Complications of central venous catheterization in critically ill children.
Analysis of central venous catheterization complications in different access sites with the Seldinger technique. Patients and Methods: A prospective study (May 1992 through December 1996) of 308 central venous catheterizations in children of different ages in a pediatric intensive care unit. ⋯ Central venous catheterization can be performed readily in children of all ages with an acceptable degree of risk. The immediate complications were more frequent and severe for subclavian vein catheterization, and the highest risk factor was the number of attempts at catheter insertion. Although the most frequent late complications were mechanical, which were higher for the femoral access and long-indwelling catheters, femoral catheters can be left indwelling for longer periods if routine ultrasound follow-up is performed. Infectious complications were independent of the venous access site or the duration of catheterization.

Organ donation in children: role of the pediatric intensive care unit.
Children waiting for organ transplants continue to die because of the shortage of available organs. Studies of organ donation in children are scarce. The evaluation of the organ donation experience in a pediatric tertiary care hospital may identify factors that influence actual organ donation rates and lead to strategies to improve pediatric organ donation. ⋯ Despite an encouraging 63% consent rate for organ donation when families are approached, only 41% of potential donors proceeded to actual donation. Strategies for a prospective pediatric study should focus on mandatory request, multicultural issues, and aggressive postconsent medical management and procurement. The pivotal role of the pediatric intensive care unit practitioner should be emphasized.

Relevance of diagnostic diversity and patient volumes for quality and length of stay in pediatric intensive care units.
Investigation of associations of the diagnostic diversity and volumes with efficiency and quality of care. ⋯ Patient volumes encountered in a PICU are important for maintaining quality and efficiency of care. In low-volume units, fewer diagnoses and higher volumes were both associated with higher efficiencies. In high volume units, diagnosis-specific volumes were generally large enough for achieving diagnosis-independent efficiency. Diagnostic mix was not associated with PICU mortality ratios, but higher PICU volumes were associated with lower mortality rates.

End-of-life decision-making and satisfaction with care: parental perspectives.
To evaluate parents' perceptions of the process by which decisions are made to limit or withdraw life support from critically ill children, and to evaluate parents' perceptions of their child's death in the pediatric intensive care unit (ICU) and their satisfaction with the care provided. ⋯ Recommendations of physicians, nature of illness and expected neurologic recovery are important to parents making end-of-life decisions for their children. The establishment of trust is crucial in guiding parents through the decision-making process. Parental presence at the time of a child's death, the provision of adequate information, and a sympathetic environment may facilitate a healthy grief response.
