There is a commonly held belief that randomized, placebo-controlled trials in pediatric critical care should incorporate "rescue" therapy (open-label administration of active drug) when a child's condition is deteriorating. The ethical, conceptual, and analytic challenges related to rescue therapy in randomized trials can be misrepresented. ⋯ Although a rescue therapy component in a randomized trial may be perceived as ethically desirable, inconsistency of rescue therapy with full equipoise may itself raise significant ethical concerns. Increased sample sizes expose more children to the risks of study participation, including death. Researchers should be aware that clinical trials designed with rescue therapy cannot definitively determine the beneficial or harmful effects of a treatment per se, and can only assess the effects of delayed vs. immediate provision of the treatment.

Neurological injury after extracorporeal membrane oxygenation use to aid pediatric cardiopulmonary resuscitation.
Extracorporeal membrane oxygenation (ECMO) to aid failed cardiopulmonary resuscitation (CPR) in children is associated with a high incidence of neurologic injury. We sought to identify risk factors for acute neurologic injury in children undergoing ECMO to aid CPR (E-CPR). ⋯ Neurologic injury is a frequent complication in children undergoing E-CPR. Children with cardiac disease, less severe metabolic acidosis before ECMO, and an uncomplicated ECMO course have decreased odds of sustaining neurologic injury. Providing effective CPR and inclusion of brain protective therapies on ECMO should be considered in the future to improve neurologic outcomes for patients undergoing E-CPR.

Ventilator-associated pneumonia (VAP) is a significant cause of secondary morbidity and mortality in adult trauma patients. No study has characterized VAP in pediatric trauma patients. We determined the rates of and potential risk factors for VAP in pediatric trauma patients. ⋯ The rate of VAP in pediatric trauma patients is substantially lower than in similar adults. Age older than 10 years, blunt trauma, head injury, and Injury Severity Score >25 may be risk factors. VAP is not associated with increased mortality in pediatric trauma patients.

Drug use density in critically ill children and newborns: analysis of various methodologies.
To compare in the pediatric, cardiac, and neonatal intensive care units, three methods of assessing vancomycin and linezolid drug use density by number of: defined daily doses (DDDs), prescribed daily doses, and days of drug use per 100 patient days. ⋯ In critically ill children, drug use density of vancomycin is significantly less when evaluated by the DDD method compared with the prescribed daily dose method, a more appropriate method in children. However, the simplest and most accurate method of assessing drug use density is the number of days of drug use method, which allows comparison of drug use density between different pediatric facilities or clinical units.
