Dear Yoshio,

 

In the time frame 1/1/14 to 6/30/2015 (18 months) we did 74 pediatric MEG studies for clinical presurgical intractable epilepsy evaluation in patients  0-18 years of age. Of these 9 received sedation with chloral hydrate and 34 received general anesthesia with dexmedetomidine. The remainder of the patients received sleep deprivation of half of their usual sleep hours the night before the study.

The recording time for the MEG study is typically 1.5 hours and of that the last 15 minutes is for SEF.

(1)    For the chloral hydrate sedation, the child typically does not fall asleep until 30-45 after PO does administration, so the sedation time is in effect the 1.5 hours, although the time after the administration of the one time  dose is therefore about 2 hours.

(2)    For the dexmedetomidine, the MEG study is often there first study on admission to the EMU, so that IV is placed (15 minute) and  EEG electrodes are placed (30-45 minute) also after GA induction so total time under GA currently is 2.5 hours. During the SEF at the end of the study we may use a small dose of Fentanyl or Propofol so that the electrical stimulus does not awaken the child.

We started  with sedation in July 2006.

  We have had no adverse events/reports.

  We do bill insurance for both kinds of sedation.  Insurance billing has been accepted by the insurance companies.

 

Please let me know if this is the information you needed or whether you needed additional or different information.

 

Doug

Dear MEG community members, as in 2012 and 2013, I am sending this request to the entire MEG community to find out whether MEG studies of infants and children have decreased or increased during the past 2 years. Please provide the information based on the attached report I prepared for 2013. Please indicate the number of studies without sedation and number with sedation. At Boston Children's Hospital, we have not done any studies with sedation yet, as we got the permission in June of this year from our hospital to use our new whole-head 384-channel babyMEG. We have been carrying out studies without sedation. We will include studies with sedation and intervention in 2016. Yoshio Okada
