This article describes the current magnetic resonance imaging (MRI) sedation service, the role of the nurse sedationist, results of clinical audits, and future issues within MRI.
Data from 2004 until 2006 were analysed to describe the percentage of children who were successfully sedated, and any complications. The recovery profile was investigated by a questionnaire of 100 consecutive cases.
Sedation was attempted in 455 cases with chloral hydrate, and 325 with temazepam and droperidol. The success rate was 97.4 and 92.6 per cent respectively. Top-up sedation was used in 10 and 29 per cent respectively. There were seven minor incidents but none required admission. Approximately 20 per cent of children were drowsy the following day.
We believe that the success of the service depends upon three main factors: the deselection of children in whom sedation is unsafe or likely to be unsuccessful, the use of appropriate drugs in limited doses, and the training of experienced nurses.
本文描述了当前的磁共振成像（MRI）镇静服务、护士镇静师的角色、临床审计结果以及MRI领域的未来问题。
分析2004年至2006年的数据，以描述成功镇静的儿童百分比及任何并发症情况。通过对100例连续病例进行问卷调查来研究恢复情况。
455例使用水合氯醛进行镇静尝试，325例使用替马西泮和氟哌利多进行镇静尝试。成功率分别为97.4%和92.6%。分别有10%和29%的病例使用了追加镇静。发生了7起轻微事件，但无一例需要住院治疗。约20%的儿童在第二天仍有嗜睡症状。
我们认为该服务的成功取决于三个主要因素：排除镇静不安全或可能不成功的儿童、使用有限剂量的合适药物以及对经验丰富的护士进行培训。
