Comparative Study
Performance of the pediatric glasgow coma scale in children with blunt head trauma.
To compare the accuracy of a pediatric Glasgow Coma Scale (GCS) score in preverbal children with blunt head trauma with the standard GCS score in older children. ⋯ This pediatric GCS for children 2 years and younger compares favorably with the standard GCS in the evaluation of children with blunt head trauma. The pediatric GCS is particularly accurate in evaluating preverbal children with blunt head trauma with regard to the need for acute intervention.

Prior evidence suggests that physicians may alter process of care based on race/ethnicity. The objective of this study was to determine whether race/ethnicity predicts whether a patient receives computed tomography of the head (head CT) during evaluation of blunt head injury. ⋯ Minority and non-Hispanic white patients may not have significantly different rates of receiving head CT during evaluation of blunt head injury. A multicenter prospective study is necessary to confirm these preliminary findings.

Randomized Controlled Trial
Laser-assisted anesthesia prior to intravenous cannulation in volunteers: a randomized, controlled trial.
Intravenous cannulation is common and painful. Absorption of topical anesthetics is limited by the stratum corneum, the outermost layer of the epidermis. A single pulse of an erbium:yttrium-aluminum-garnet (Er:YAG) laser irradiation can remove an area of the stratum corneum, leading to enhanced uptake of topical agents, such as lidocaine, while leaving the rest of the epidermis intact. ⋯ Pretreatment of the skin with a laser device followed by a 5-minute topical lidocaine application reduces the pain of IV cannulation in volunteers.

Randomized Controlled Trial Comparative Study
Beneficial effects of albuterol therapy driven by heliox versus by oxygen in severe asthma exacerbation.
To determine and define the beneficial effects of heliox-driven albuterol therapy on severe asthma exacerbation and clinical factors that affect greater response. ⋯ Heliox-driven albuterol may be a useful adjunct therapy for older asthmatic patients with severe asthma exacerbation.

Comparative Study
The accuracy and completeness of data collected by prospective and retrospective methods.
To describe and test a model that compares the accuracy of data gathered prospectively versus retrospectively among adult emergency department patients admitted with chest pain. ⋯ Information obtained retrospectively from the abstraction of medical records is measurably less accurate than information obtained prospectively from research subjects. For certain items, more than half of the information is not available. This loss of information is related to the data types included in the study and by the assumptions that a researcher performing a retrospective study makes about implied versus explicitly stated responses. A model of information flow that incorporates the concepts of reliability and validity can be used to measure some of the loss of information that occurs at each step along the way from subject to clinician to medical record abstractor.
