Randomized Controlled Trial Comparative Study
Comparison of Two Different Intranasal Doses of Dexmedetomidine in Children for Magnetic Resonance Imaging Sedation.
Anaesthetic agents used for magnetic resonance imaging (MRI) in paediatric patients should cause few adverse effects and allow fast anaesthetic induction and recovery. The administration route is also important and should be minimally invasive. In this study, we aimed to compare two different doses of intranasal dexmedetomidine applied to children for MRI sedation. ⋯ Based on lower rescue anaesthetic requirements, sufficient sedation and parental separation scores in Group 2, intranasal dexmedetomidine 4 µg kg(-1) was more efficient than intranasal dexmedetomidine 3 µg kg(-1). The intranasal route may be an alternative noninvasive route to apply drugs for MRI sedation in paediatric patients. Trial registration ClinicalTrials.gov: NCT02299232.

Pertussis is a potentially severe respiratory disease, which affects all age groups from young infants to older adults and is responsible for an estimated 195,000 deaths occurred globally in 2008. Active research is ongoing to better understand the pathogenesis, immunology, and diagnosis of pertussis. For diagnosis, molecular assays (e.g., polymerase chain reaction) for detection of Bordetella pertussis have become more widely available and support improved outbreak detection. ⋯ Continued surveillance for pertussis will be important to identify opportunities for reducing young infants' exposure and reducing the impact of outbreaks among school-aged children. Laboratory-based surveillance for newly emerging strains of B. pertussis will be important to identify strains that may evade protection elicited by currently available vaccines. Efforts to develop new-generation pertussis vaccines should be considered now in anticipation of vaccine development programs, which may require ten or more years to deliver a licensed vaccine.
