Children are sedated for diagnostic procedures, such as magnetic resonance imaging (MRI), due to developmental factors, which can result in uncooperative behavior that decreases exam quality. Non-interventional diagnostic radiologic procedures, such as MRI alone, pose little risk to the patient. Use of sedation during these exams increases the risk of sedation-related complications. The rates of sedation-related adverse events in children, including desaturation and decreased blood pressure, range from 0.4% to 20.1% in the United States (Malviya, Voepel-Lewis, & Tait, 1997;Sanborn et al., 2005). The number of children requiring sedation is growing, increasing the need for nurses (RNs) to provide this service (Barbi et al., 2003;Lininger, 2004). Yet, differences in frequency and types of sedation-related adverse events when sedation is provided by an RN or physician (MD) are unknown. Pediatric sedation-related complications, based on multi-center data from 30,037 records in a sample of MD-provided sedation, found 339.6 per 10,000 total sedation adverse events and 111.9 per 10,000 unplanned treatments . MDs in this study were from various specialties, such as pediatrics and radiology, and had varying sedation experience, but whether this was significant was not examined. The role the RN had in sedations was not described, although RNs often sedate children alone or with an MD.Accreditors such as the Joint Commission (TJC), formerly the Joint Commission on Accreditation of Hospitals, requires evidence of sedation provider competence, but does not specify how competence is established (Patterson, 2002; Pitetti et al., 2006). As a result, RNs (excluding Certified Registered Nurse Anesthetists [CRNA]) and MDs (excluding The general instructions regarding submission (including cover letter, title page requirements, contributor's statement page, journal style guidance, and conflict of interest statements) also apply to Case Reports.
