Summary
The goal of this study is to determine if there is a significant difference in the quality of care between the investigators' two standard anesthesia techniques for children undergoing a MRI of the body and/or extremity MRI. Quality of care will be measured by time spent in the MRI room as well as parental satisfaction, frequency of interruptions of the MRI scan, incidence-severity of respiratory complications, post anesthesia agitation, and time spent in the induction room, MRI room, and Post-Anesthesia Care Unit (PACU).

Criteria
Inclusion Criteria:

1. Subjects presenting as out-patients, scheduled to receive an anesthetic for MRI of
body (spine, chest, abdomen, and/or pelvis) and/or extremity (arm and/or leg).

2. The subject must be a candidate for both anesthetic techniques. This decision will be
made by a staff member of the Department of Anesthesiology. This staff member will not
be a member of the study team and will obtain the consent for Anesthesia.

3. The subjects must be 12 months to 7 years (inclusive of the seventh year).

4. The subject's legally authorized representative has given written informed consent to
participate in the study.

Exclusion Criteria:

1. The subject is residing in the Pediatric Intensive Care Unit, the Cardiac Intensive
Care Unit, or Neonatal Intensive Care Unit.

2. Anxiolytic medication is ordered before the MRI (e.g., midazolam or ketamine).

3. The subject has a history or a family (parent or sibling) history of malignant
hyperthermia.

4. The subject has life-threatening, medical conditions (American Society of
Anesthesiologists Physical Status 4, 5 or 6).

- The American Society of Anesthesiologists (ASA) classification scale is a measure
of physical status or how healthy the patient is.

- For our study, we will focus on children which are defined as ASA I, II or III
which means a healthy child (ASA I), a child with a systemic disease that is mild
and well controlled (ASA II) or a child with systemic disease that is severe and
controlled (ASA III).

5. The subject is allergic to or has a contraindication to any of the drugs used in the
study.

6. The subject has previously been treated under this protocol.

7. The subject has a tracheostomy or other mechanical airway device.

8. The subject has received within the past 12 hours an oral or intravenous
alpha-adrenergic, beta-adrenergic agonist, or antagonist drugs (e.g., clonidine,
propranolol, albuterol).

9. The subject is not scheduled to receive anesthesia-sedation care for the MRI.

10. The subject received one of the anesthetic regimens for the same MRI during the past
six months.
