A Comparison of Dexmedetomidine-Midazolam with Propofol for Maintenance of Anesthesia in Children Undergoing Magnetic Resonance Imaging
Anesthesia & Analgesia. 107(6):1832-1839, December 2008.
Abstract
BACKGROUND: Dexmedetomidine is an [alpha]2 agonist that is currently being investigated for its suitability to provide anesthesia for children. We compared the pharmacodynamic responses to dexmedetomidine-midazolam and propofol in children anesthetized with sevoflurane undergoing magnetic resonance imaging (MRI).
METHODS: Forty ASA 1 or 2 children, 1-10 yr of age, were randomized to receive either dexmedetomidine-midazolam or propofol for maintenance of anesthesia for MRI after a sevoflurane induction. Dexmedetomidine was administered as an initial loading dose (1 [mu]g/kg) followed by a continuous infusion (0.5 [mu]g [middle dot] kg-1 [middle dot] h-1). Midazolam (0.1 mg/kg) was administered IV when the infusion commenced. Propofol was administered as a continuous infusion (250-300 [mu]g [middle dot] kg-1 [middle dot] min-1). Recovery times and hemodynamic responses were recorded by one nurse who was blinded to the treatments.
RESULTS: We found that the times to fully recover and to discharge from the ambulatory unit after dexmedetomidine administration were significantly greater (by 15 min) than those after propofol. Analysis of variance demonstrated that heart rate was slower and systolic blood pressure was greater with dexmedetomidine than propofol. Respiratory indices for the two treatments were similar. During recovery, hemodynamic responses were similar. Cardiorespiratory indices during anesthesia and recovery remained within normal limits for the children's ages. No adverse events were recorded.
CONCLUSION: Dexmedetomidine-midazolam provides adequate anesthesia for MRI although recovery is prolonged when compared with propofol. Heart rate was slower and systolic blood pressure was greater with dexmedetomidine when compared with propofol. Respiratory indices were similar for the two treatments.

The Reproducibility of Quantitative Measurements in Lumbar Magnetic Resonance Imaging of Children From the General Population
Spine. 33(19):2094-2100, September 1, 2008.
Abstract
Study Design. Quantitative lumbar magnetic resonance imaging (MRI) measurements in children were taken twice and analyzed for intra- and intertester reproducibility.Objective. To evaluate the reproducibility of a variety of lumbar quantitative measurements taken from MRIs of children from the general population.Summary of Background Data. The reproducibility of lumbar quantitative measurements has never been tested on MRIs of children from the general population. This is a prerequisite for a reliable anatomic characterization of the immature spine in normal and pathologic conditions.Methods. Lumbar quantitative measurements from 40 T2-weighted lumbar (L1-S1) MRIs of children from the general population were taken twice by 1 tester for intratester reproducibility and compared with the same measurements (L4-S1) of the same MRIs taken by a second tester for intertester reproducibility. The following parameters were measured using the iQ-VIEW system (IMAGE Information Systems Ltd., version 1.2.2, Plauen, Germany): Linear measurements-zygoappophyseal facets and interfacet widths, and vertebral body (VB), pedicle and intervertebral discs heights, widths, and lengths. Angular measurements-zygoappophyseal tranverse superior facet angles, sagittal VB, and disc wedging, lumbar lordosis, and sacral inclination. Statistical analysis included the concordance correlation coefficient (CCC), and Bland and Altman's limits of agreement (LOA).Results. A total of 6160 measurements were analyzed. Good to excellent intratester reproducibility (0.75 <=CCC <=0.99) was indicated for all linear measurements (except for pedicle heights) (LOA: -4.76; 5.74 mm) and for angular measurements related to the facets orientation, lumbar lordosis, and sacral inclination (LOA: 11.22[degrees]; 12.34[degrees]). VB and disc sagittal wedging manifested poor intratester reproducibility
