Comparison between intranasal dexmedetomidine and intranasal midazolam as premedication for brain magnetic resonance imaging in pediatric patients: A prospective randomized double blind trial
Background and Aims: Preprocedural preparation of children scheduled for magnetic resonance imaging (MRI) is challenging. This prospective, randomized trial compared intranasal midazolam with intranasal dexmedetomidine as premedication for children scheduled for brain MRI. Material and Methods: In t...

This prospective, randomized trial compared intranasal midazolam with intranasal dexmedetomidine as premedication for children scheduled for brain MRI. Material and Methods: In total, 60 children, aged 1–8 years, scheduled for elective brain MRI, were randomly assigned to the intranasal dexmedetomidine (1 μg/kg; Group D) or intranasal midazolam (0.2 mg/kg; Group M) group. We compared hemodynamic and respiratory parameters, onset, level, sedation quality, and successful parental separation. All patients received intravenous propofol as an induction and maintenance agent for MRI. Results: No significant differences were observed in demographic, hemodynamic, and respiratory parameters. Group D (14.3 ± 3.4 min [10–20 min]) had a longer time of sedation onset than Group M (8.7 ± 3.7 min [5–15 min]; P < 0.001). The median and mean sedation scores were lower in Group D (3 and 3.7 ± 0.8, respectively) than Group M (4 and 4.3 ± 1.2, respectively; P = 0.055). Group D (80%) had a higher percentage of children achieving satisfactory sedation at the time of induction than did Group M (53.3%; P = 0.0285). Parental separation was successful in 73.3% of patients in Group D compared with 46.7% of patients in Group M (P = 0.035). Conclusion: Intranasal dexmedetomidine results in more successful parental separation and yields a higher sedation level at the time of induction of anesthesia than intranasal midazolam as premedication, with negligible side effects. However, its onset of action is relatively prolonged.http://www.joacp.org/article.asp?issn=0970-9185;year=2017;volume=33;issue=2;spage=236;epage=240;aulast=GuptaDexmedetomidinemidazolamintranasalmagnetic resonance imaging |

Background and Aims: Preprocedural preparation of children scheduled for magnetic resonance imaging (MRI) is challenging. This prospective, randomized trial compared intranasal midazolam with intranasal dexmedetomidine as premedication for children scheduled for brain MRI.
Material and Methods: In total, 60 children, aged 1–8 years, scheduled for elective brain MRI, were randomly assigned to the intranasal dexmedetomidine (1 μg/kg; Group D) or intranasal midazolam (0.2 mg/kg; Group M) group. We compared hemodynamic and respiratory parameters, onset, level, sedation quality, and successful parental separation. All patients received intravenous propofol as an induction and maintenance agent for MRI.
Results: No significant differences were observed in demographic, hemodynamic, and respiratory parameters. Group D (14.3 ± 3.4 min [10–20 min]) had a longer time of sedation onset than Group M (8.7 ± 3.7 min [5–15 min]; P < 0.001).
