purpose: To compare the sedation effects of two intranasal methods of dexmedetomidine for magnetic resonance imaging (MRI) in children. Method: 40 children for MRI were randomly divided into two groups, namely 20 cases for each group: nasal drip group(group A)and nasal spray group(group B). Group A and group B received intranasal dexmedetomidine of 1.5 ug/kg by two methods. Monitoring the HR, SpO2, RR and inspection time of the two groups so as to observe the sedation effects and Ramsay

Compared with group A,the timeto-fall-asleep in group B was shorter and the adverse reactions significantly decreased(P<0.05).Conclusion: Compared with nasal drip,nasal spray dexmedetomidine by MAD can shorten the time-to-fall-asleep and reduce adverse reactions for MRI in children.
