First report of application of Magnetic Resonance without sedation in neonates.

Abstract

Introduction:  Magnetic Resonance Image tends to be a more progressively-accessible study for neonates, even without sedation. Aim: to highlight its utility, with no sedation in neonates, in detection and characterization of cerebral lesions with neurological damage manifestations. Method:  an observational-explicative-prospective preliminary report, which included 10 neonates at Comandante ¨Manuel Piti Fajardo¨ at Obstetric and Gynecologist Teaching Hospital, between 2013- 2015 years. Initially, brain ultrasound was done. Posterior, Magnetic Resonance Image was performed. Results: 70% was reported as low weight, 60% as preterm and cesarean done. In all neonates, several lesion patterns were determined. New lesions were detected by Magnetic Resonance Image in 80% of neonates, which were not seen previously by brain ultrasound. 20% of newborns had hypoxic-ischemic encephalopathy and all of them revealed typical patterns of it, even in 10% of which no injury was diagnosed previously. Conclusions: The majorities of neonates included in this present report were preterm, low weight and delivered by cesarean. In all patients, the patterns of detection and characterization of cerebral lesions by Magnetic Resonance with no sedation were accomplished. It was shown its utility in neonates, in relation to previous brain ultrasound findings, as well as the identification of newborns hypoxic-ischemic encephalopathy
