Pediatric anesthesia & critical care
Intranasal dexmedetomidine sedation for paediatric MRI by radiology personnel: A retrospective observational study
Authors' conclusion
Intranasal dexmedetomidine sedation without immediate presence of anaesthesia personnel appears to be well tolerated and associated with minimal interference on MRI image quality.
Study context
- Population
- Children 0 to 12 years, ASA 1 or 2, HR within age-appropriate limit, undergoing MRI at a tertiary care paediatric hospital
- Participants
- 1,091 MRIs
- Outcome
- Changes in haemodynamic and respiratory data before vs after intranasal dexmedetomidine, incidence of critical events, rate of successful MRI scans
