Use of the injury severity score to predict nosocomial bloodstream infections among critically ill trauma patients.
Nosocomial bloodstream infections (NBSI) are associated with increased hospital length of stay (LOS), mortality, and costs. At this writing, no available reports describe the association between injury severity and NBSI among critically ill adult trauma patients. This study aimed to examine the use of the Injury Severity Score (ISS) as a predictor of NBSI among critically ill adult trauma patients. ⋯ The mean LOS until the diagnosis of NBSI was significantly lower than the total LOS of the control subjects (odds ratio [OR], 0.959; 95% confidence interval [CI], 0.93-0.99). The ISS score and age were found to be independent predictors of NBSI. The findings provide a means for using the ISS score as a predictor of NBSI in the critically ill adult trauma population.

ReviewManagement of respiratory syncytial virus with lower respiratory tract infection in infants and children.
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection in infants and children requiring pediatric hospitalizations. Infants with chronic lung, cardiac, or neuromuscular conditions are at increased risk for RSV infection. Early RSV is associated with subsequent diagnosis of reactive airway disease. ⋯ Interventions include supplemental oxygen therapy, ventilation, and fluid and nutrition therapy. Respiratory syncytial virus prophylaxis for high-risk patients includes intramuscular injections of palivizumab (Synagis) each month during RSV season, from November through April. Prevention strategies include washing hands, cleaning environment surfaces, and isolating infants and children with RSV in the emergency care area.

Coagulopathy after traumatic injury has multiple etiologies. It may result from overwhelming activation of tissue factor, consumption of circulating coagulation proteins, massive transfusion, metabolic alterations, hypothermia, or any combination of these factors. ⋯ Development of a coagulopathy has a significant impact on the morbidity and mortality of the patient with trauma. This article describes the relevant pathophysiology as it relates to the development of a coagulopathy, prevention strategies, and management principles applied in caring for the patient with trauma and a coagulopathy.

ReviewSickle cell anemia in the pediatric intensive care unit: novel approaches for managing life-threatening complications.
Although the manifestations of sickle cell disease (SCD) do not typically necessitate critical care management, several life-threatening complications may require admission to the pediatric intensive care unit. Children with SCD are at risk for serious complications such as vaso-occlusive pain crises, cerebral vascular accidents, acute chest syndrome, severe anemia related to aplastic and splenic sequestration crises, infection, and multiorgan failure. Despite years of study, little progress has been made in understanding the pathophysiology of SCD. ⋯ Perhaps most exciting are the advances in bone marrow and stem cell transplantation, which offer hope of an eventual cure for this debilitating and deadly disease. Advanced practice nurses play a pivotal role in coordinating care for these critically ill children. Knowledge of both current and investigational therapies allows the advanced practice nurse to provide comprehensive, state-of-the-art care to children with life-threatening complications of SCD.

Pediatric patients are not just "little adults" and elderly patients are not just "old adults." The elderly patient experiences physiologic and anatomic changes that affect all body systems. Providing trauma care for the elderly presents a particular challenge. ⋯ Preexisting health conditions further complicate the picture. This article highlights some of the important differences in caring for an elderly trauma patient from resuscitation to rehabilitation.
