OBJECTIVE High incidence, rising admission rates, and relatively ineffective therapies make the management of bronchiolitis controversial. Since 1980, the rate of hospitalization for children with bronchiolitis has increased by nearly 250%, whereas mortality rates for the disease have remained constant. It has been speculated that the increasing use of(More)
STUDY OBJECTIVE We describe the adverse events observed in a large sample of children sedated with propofol by emergency physicians and identify patient and procedure characteristics predictive of more serious adverse events. METHODS We identified sedations performed by emergency physicians using propofol as the primary sedative, included in the Pediatric(More)
OBJECTIVE To compare efficacy, sedation duration, and adverse events after administration of etomidate or pentobarbital for diagnostic computed tomography (CT) scans. METHODS A cohort of children sedated for CT scans between July 2004 and October 2005 was identified from a prospectively generated Pediatric Sedation Research Consortium database. The 24(More)
BACKGROUND Pentobarbital and propofol are commonly used to sedate children undergoing magnetic resonance imaging (MRI). The Pediatric Sedation Research Consortium (PSRC) was created in 2003 to improve pediatric sedation process and outcomes. OBJECTIVE To use PSRC records to compare the effectiveness, efficiency and adverse events of propofol vs(More)
OBJECTIVE Observation units (OUs) have emerged as a cost-saving alternative to traditional ward admission for many pediatric illnesses. Dehydration caused by gastroenteritis is a common reason for admission to a pediatric OU. In this study, we describe characteristics of patients with presumed gastroenteritis admitted to a pediatric OU and seek to identify(More)
The primary purpose of this study was to develop a clinical tool capable of identifying discriminatory characteristics that can predict patients who will return within 72 hours to the Pediatric emergency department (PED). We studied 66,861 patients who were discharged from the EDs during the period from May 1 2009 to December 31 2009. We used a(More)
OBJECTIVES To evaluate the impact of obesity on adverse events and required interventions during pediatric procedural sedation. METHODS The Pediatric Sedation Research Consortium database of prospectively collected procedural sedation encounters was queried to identify patients for whom body mass index (BMI) could be calculated. Obesity was defined as BMI(More)
OBJECTIVES To describe the frequency of different physiologic monitoring modalities and combinations of modalities used during pediatric procedural sedation; to describe how physiologic monitoring varies among different classes of patients, health care providers (ie, ranging from anesthesiologists to emergency medicine physicians to nurse practitioners),(More)
BACKGROUND The American Heart Association recommends a "meticulous history" when evaluating patients with an initial episode of syncope. However, little is known about which historical features are most helpful in identifying children with undiagnosed cardiac syncope. OBJECTIVES Our objectives were 1) to describe the cardiac disease burden in Emergency(More)
