  ABSTRACT: Nitrous oxide is an inhaled agent commonly used by dental staff to provide anxiolysis and analgesia for dental procedures and by anesthesia personnel as an adjunct to more potent general anesthetic gases. More recently, nitrous oxide has been used to provide sedation/analgesia for a variety of medical procedures in children outside of the operating room, including lumbar puncture, laceration repair, fracture reduction, and urologic imaging. We report 3 cases of clinical seizure activity associated with nitrous oxide administration for pediatric procedural sedation. Although temporally related, no causality is established. Review of the medical and dental literature confirm the rarity of these events.

  ABSTRACT: In the initial assessment of children with new-onset seizures, the suggestion that electroencephalography (EEG) should be standard and that magnetic resonance imaging (MRI) should be optional has been questioned. The purposes of this study were to (1) describe the frequency of EEG and MRI abnormalities and (2) explore relationships between MRI and EEG findings to determine their relevance in the assessment of children with new-onset seizures who are otherwise developing normally. As part of an ongoing, prospective study of children with new-onset seizures, we studied 181 children (90 girls and 91 boys). Children were entered into the study within 3 months of their first-recognized seizure. The association between EEG and MRI abnormalities was explored using a chi-square test. Abnormal MRI findings were found in 32.6% (n = 59) of the sample. The EEG and MRI results agreed with respect to classification into normal or abnormal in 37% (n = 67). Of the 50 children with a normal EEG, however, 21 (42%) were found to have an abnormal MRI. We found an unexpectedly high frequency of imaging abnormalities in our sample of otherwise normal children, although the significance of these findings is not clear. Follow-up of these patients will help us interpret the importance of the abnormalities. Despite our relatively small sample, however, our findings indicate that a normal EEG does not reliably predict a normal MRI in children with first seizures.
