DELGADO, Jorge Andrés et al. The Use of Profound Sedation Assisted by the Anesthesiologist in Pediatric Patients Undergoing MRI. Rev. colomb. anestesiol. [online]. 2010, vol.38, n.4, pp.487-497. ISSN 0120-3347.

Objetive. Obtaining diagnostic quality images in the pediatric population using magnetic resonance imaging, requires the use of deep sedation assisted by the anesthesiologist to ensure the total immobility of the patient for an adequate examination. Objective. To describe the use of deep sedation assisted by an anesthesiologist in magnetic resonance studies for the pediatric population. Methodos. Observational study of a series of cases. 113 randomly selected MRI scans, with assisted sedation by an anesthesiologist in pediatric patients aged less than 15, treated at the Fundación Instituto de Alta Tecnología Médica de neAntioquia in 2009. The inter-observer consistency was evaluated in 84 examinations with their corresponding series of images. Results. Average sedation time for the most common MRIs were are follows: cerebral MRI, 45.2 ± 12.4 minutes; cerebral with contrast, 46.3 ± 16.7 minutes; cardiac, 96 ± 24.1 minutes; cerebral angiography, 60 ± 16.8 minutes and cerebral-total spine, 76.3 ± 32 minutes. No significant gender-adjusted differences were found (p > 0.05). The sedatives used for these examinations were: midazolam, ketamine, propofol, chloral hydrate and fentanyl. Excellent inter-observer consistency was found in terms of the reliability of the series of images of deep sedation patients (Kappa > 0.9). Conclusions. Sedation assisted by an anesthesiologist is considered a procedure with a low rate of complications that can be used more often in the pediatric population for obtaining diagnostic quality images in patients with co-morbidities and in complex MRI procedures.
