Fractures in the Pediatric Emergency Department: Are We Considering Abuse?

Approximately one fourths of infant fractures are due to abuse. Recognition of abuse is important to avoid further morbidity/mortality. There is limited knowledge regarding how frequently pediatric emergency department clinicians consider abuse in infants with fractures. Our primary objective was to estimate the percentage of infants with fractures for whom abuse was considered, and to examine characteristics associated with abuse consideration. We performed a retrospective review of infants <1 year of age presenting to a pediatric emergency department. Our primary outcome variable was consideration of abuse. Our secondary outcome measures were identification of predictor variables associated with consideration of abuse. We identified 509 infants meeting study criteria. Pediatric emergency physicians considered abuse in approximately two thirds of infants with fractures. Consideration was more likely to occur in younger infants, in the presence of no history or unwitnessed injury mechanism, when evaluated by male physicians, and emergency department encounters from 12 am to 6 am.

A multiyear assessment of a hospital-school program to promote teen motor vehicle safety.

BACKGROUND: Motor vehicle crashes are the leading cause of death among teen drivers. The main goal of this program was to reduce texting while driving among high school teens through a unique peer-generated anti-texting campaign. METHODS: The program consisted of two phases. In phase 1, student leaders participated in a half-day, hospital-based experiential program that emphasized safe teen driving. In phase 2, these students conceptualized and implemented an anti-texting while driving campaign during the school year. The program enrolled 32 schools with 137 student participants in phase 1. This study uses a prospective quasi-experimental pre-post design. A presurvey and a follow-up online survey were used. Response rate was 81%. In phase 2, two rounds of observations of drivers were made near the participating schools at the beginning and end of the phase 2 campaign. The results were analyzed using proportion tests. RESULTS: There was a strong belief (6.49 on a seven-point scale) that texting while driving could result in a crash. About 58% had texted while driving in the previous 7 days in the pre-survey. This proportion decreased significantly to 44% in the follow-up (p < 0.05). Knowledge of Tennessee Graduated Driver Licensing laws and feeling of empowerment to take action with a teen driver who was texting improved significantly (p < 0.05). In phase 2, 12,309 drivers (adults and teens) were observed in the first round, and 13,153 were observed in the second round of observations. Significant reduction in the proportion of drivers texting while driving (from 13% to 9%; p < 0.0001) was observed. CONCLUSION: Results of driver observations support the effectiveness of this program in meeting the key objective of reducing texting while driving. The program also influenced teenagers' willingness to take positive steps when faced with a driver who was texting. Future efforts should aim to influence social and peer norms. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Intravenous hypertonic saline use in the pediatric emergency department.

OBJECTIVES: The objective of this study was to describe the use, dosing, and administration of intravenous hypertonic saline (IHS) use in a pediatric emergency department. METHODS: This was a retrospective chart review of patients 0 to 18 years receiving IHS as part of their management in a pediatric ED with an annual volume of more than 50,000 visits. RESULTS: Over 4 years, 56 patients received IHS as part of their management in the emergency department. Clinical scenarios for IHS administration included traumatic brain injury with concern for increased intracranial pressure in 19 patients (34%), diabetic ketoacidosis with altered mental status in 18 (32%), hyponatremia without seizure activity in 6 (10.7%), hyponatremic seizure in 3 (5.4%), and altered mental status secondary to a nontraumatic, non-diabetic ketoacidosis cause in 10 (17.9%). The median age of the patients was 11.3 years (interquartile range, 6-13.9 years) receiving a median dose of 4.1 mL/kg (interquartile range, 3.08-5 mL/kg) of IHS. The median time for administration of the IHS was 17 minutes, with 87% of doses given via peripheral intravenous catheters. Approximately one fourth (26.8%) of patients received their dose in 10 minutes or less, with 7.2% of patients receiving a bolus of IHS in 3 minutes or less. We found no evidence of adverse effects. CONCLUSIONS: Intravenous hypertonic saline use is increasing within the pediatric emergency department. Within this institution, it is most frequently used at a dosing range of 3 to 5 mL/kg and does not require central venous access for rapid infusion.

Procalcitonin as a marker of severe bacterial infection in children in the emergency department.

Procalcitonin, the prohormone of calcitonin, is a relatively new and innovative marker of bacterial infection that has multiple potential applications in the pediatric emergency department. In healthy individuals, circulating levels of procalcitonin are generally very low (<0.05 ng/mL), but in the setting of severe bacterial infection and sepsis, levels can increase by hundreds to thousands of fold within 4 to 6 hours. Although the exact physiologic function of procalcitonin has not been determined, the consistent response and rapid rise of this protein in the setting of severe bacterial infection make procalcitonin a very useful biomarker for invasive bacterial disease. In Europe, serum procalcitonin measurements are frequently used in the diagnosis and the management of patients in a variety of clinical settings. To date, the use of procalcitonin has been limited in the United States, but this valuable biomarker has many potential applications in both the pediatric emergency department and the intensive care unit. The intent of this article is to review the history of procalcitonin, describe the kinetics of the molecule in response to bacterial infection, describe the laboratory methods available for measuring procalcitonin, examine the main causes of procalcitonin elevation, and evaluate the potential applications of procalcitonin measurements in pediatric patients.
