ABSTRACT

Given that hypothermia cases have occurred in newborns after MRI with anesthesia and reproducing what was observed in centers visited overseas, we implemented a supervised protocol to evaluate the results of cerebral MRI performed without anesthesia or sedation in patients hospitalized in our institution. Objective: To display results of the protocol for performing cerebral MRI without anesthesia in our newborn patients. Materials and methods: A retrospective study, we evaluated cerebral MRI performed on newborns from september 2012 - july 2013. Protocol for performing MRI without anesthesia was applied in institutionalized patients. Variables are compared with MRI performed using anesthesia, during this period. Results: 22 cerebral MRI were performed, 14 without anesthesia. The duration of the study without anesthesia was 48 minutes on average, obtaining adequate images in 13 studies, reprogramming the examination with anesthesia in one case. Conclusions: The protocol implemented allows the acquisition of diagnostic-quality cerebral MRI, obviating the anesthesia.


Dado casos de hipotermia en recién nacidos (RN) posterior a resonancia magnética (RM) con anestesia y reproduciendo lo observado en centros extranjeros visitados, implementamos protocolo supervisado para evaluar los resultados de RM encefálicas realizadas sin anestesia o sedación en pacientes hospitalizados en nuestra institución. Objetivo: Mostrar resultados del protocolo para realización de RM encefálica sin anestesia en nuestros pacientes RN. Materiales y métodos: Estudio retrospectivo, evaluamos RM encefálicas realizadas en RN entre septiembre 2012 - julio 2013. Se aplicó protocolo para realización de RM sin anestesia en pacientes institucionalizados. Se comparan variables con RM realizadas con anestesia en ese periodo. Resultados: Se realizaron 22 RM encefálicas, 14 sin anestesia. La duración del estudio sin anestesia fue de 48 minutos promedio, obteniendo imágenes adecuadas en 13 estudios, reprogramando el examen con anestesia en un caso. Conclusiones: el protocolo implementado permite obtener RM encefálicas de calidad diagnóstica, obviando la anestesia.
