Comparison of Bispectral Index Values in Patients With and Without Down's Syndrome

Intervention / Treatment
Detailed Description
Based on the Valkenburg group's study (2009), one might hypothesize that if the BIS value is fixed for all patients, then a patient with an intellectual disability such as a patient with DS would require less anesthetic drugs compared to a control patient without any neurological disability. However, if one is only using a clinical sedation scale, the DS patient may receive more anesthetic drugs in order to achieve the same level of clinical unconsciousness as a patient without DS.
This project seeks to elucidate the effect of anesthetic techniques and agents on patients with DS compared to those without DS and any intellectual disability. The goal of this project is to compare BIS values in patients with DS to those without DS undergoing a standardized general anesthetic technique. The investigators hypothesize that patients with DS would have lower (>25%) BIS values compared to those without DS.
Known potential sources of artifact signals that could change BIS values include electromyographic activity, electric devices, hypothermia, hypoglycemia, and the timing and type of anesthetics used (Duarte 2009, Dahaba 2005). These potential sources will be identified and reported during the study, and those patients will be excluded from the study

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Normal
This is the group with no neurological problems or syndrome
|
We will be monitoring BIS in both groups.
A BIS monitor may be placed prior to induction or immmeditaely afterwards for monitoring BIS.
All patients will receive general anesthesia.
A standard inhalation induction agent such as sevoflurane and oxygen will be administered via face mask with or without an oral airway.
An inhalation agent will be administered for the duration of the procedure.
The MAC goal for inhalation agents will be 1.
If the patient moves, the MAC goal will be increased to 1.5 and this change will be recorded.
