Summary
The number of children undergoing MRI imaging has increased significantly in the past years, because many young children cannot stay still for the duration of the scan, have difficulty tolerating the confined space and the noise produced by the Magnetic Resonance Imaging (MRI) machine, sedation or General Anesthesia is required in these cases. In the investigators institution, the investigators use General Anesthesia for children undergoing MRI.
Because children have a larger surface area to body weight ratio; hypothermia from passive heat loss is one of the anesthesiologists' concerns.
MRI requires a cool environment with low humidity; this specialized environment represents a significant thermal challenge to the anesthetized children. Since most temperature devices are not compatible with the MRI, the simple task to measure temperature change has never been investigated.
Eligibility Criteria
Inclusion Criteria
- 6 months to 8 years undergoing general anesthesia for elective MRI of brain, spine and extremities. Patients who were ASA physical status 1-3 only were included.
exclusion criteria: Patients who were ASA 4-5 were excluded from the study. Patients not NPO for solids for 8 hours and liquids for 2 hours were excluded.
