About

An increasing number of children undergo Magnetic Resonance Imaging (MRI). In MRI, radio waves and magnetism are used to form images of the body's interior, to diagnose and monitoring diseases in children. Many children are sedated to be able to collaborate with the MRI procedure. Sedation and general anesthesia cause the child to some extent to lose the ability to regulate his or her own bodytemperature. MRI rooms are most often cold due to the function of the magnet, leading to a risk of hypothermia in young children. Conversely, the MRI scanner generates radio frequencies that are absorbed by the body and converted to heat, which especially in small children due to their large surface area can potentially result in an increase in bodytemperature. In this study we therefore want to investigate changes in bodytemperature in children who are undergoing MRI- scanning within the Neuroanesthesiology Clinic. Furthermore, we want to define possible risk factors for possible temperature changes. Our hypothesis: Children undergoing MRI scanning increase in bodytemperature.

Full description

Ear temperature is measured as we are primarily interested in describing temperature changes in the individual child and because this method is less invasive than the alternatives.

Enrollment: 74 patients

Sex: All

Ages: 12 weeks to 12 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Age from 12 weeks to 12 years
• Children undergoing MRI scans with the help of anesthesia staff from the Neuroanesthesiology Clinic under general anesthesia or awake
• The children are recruited via prescriptions or the anesthetist immediately before scanning and outside the MRI room. All children who meet the criteria for MRI scan can be included. Acute MRI children, children admitted to intensive care and children who came is directly from the operation if consent is obtained.

Exclusion criteria
