Abstract

Background: Patients’ co-operation or immobilization is required in Magnetic Resonance Imaging (MRI) procedure. Different techniques of anesthesia assist pediatric patients in controlling their movement. Our objective was to retrospective review and report anesthetic techniques used as well as incidence of complications associated with anesthesia.


Methods: Data of 383 pediatric patients aged between 0-6 years in from May 2012 to December 2013 in Siriraj Hospital were retrospectively chart review. The demographic characteristics, diagnosis, anesthetic techniques, duration of the procedure and complications were collected and analyzed in descriptive statistic.


Results: During the study period, there were 383 patients receiving MRI procedure under caring by anesthesiologists, excluded cardiac MRI. The majority of patients was in age group of 0-12 months (41.8%) and classified as ASA classification of 1-2 (93.2%). The main anesthetic of choice was intravenous sedation with inhalation insufflation (53.3%). The first and second most common complications were bradycardia and hypotension accounting for 1.2% and 0.8% respectively.


Conclusion: The most popular anesthetic technique used in MRI procedure in Siriraj Hospital was intravenous sedation with inhalation insufflation. Although the low incidence of adverse effects was shown, anesthetic personnel should be aware of any complication that may occur in anesthesia of pediatric patients undergoing MRI procedure.
