BACKGROUND
With a longer waiting list for paediatric MRI performed under general anaesthesia (GA) and considering safety concerns, the Royal Children's Hospital Brisbane established a mock MRI service. The aim of this service is to reduce the requirement for MRI under GA.
OBJECTIVE
The objective of this study was to test the hypothesis that the percentage of children ages 3 years to 14 years in the study period that required general anaesthesia would be less with mock MRI when compared to standard practise.
MATERIALS AND METHODS
A retrospective audit of clinical data was conducted to examine the impact of mock MRI on the GA rate for clinical MRI.
RESULTS
Results indicated the addition of a mock MRI reduced the need for GA most significantly for children ages 3 to 8 years. In this age group, the rate of GA was 16.8% lower than that of the non-mock MRI group (P = <0.05).
CONCLUSION
Mock MRI reduces the need for GA in children with the greatest effect evident in children aged between 3 and 8 years.
背景
由于儿科磁共振成像（MRI）在全身麻醉（GA）下的等待时间较长，且考虑到安全性问题，布里斯班皇家儿童医院设立了一个模拟 MRI 服务。该服务的目的是减少 GA 下 MRI 的需求。
目的
本研究旨在检验以下假设，即在研究期间，接受模拟 MRI 的 3 至 14 岁儿童中需要全身麻醉的比例将低于标准实践。
材料和方法
对临床数据进行回顾性审计，以检查模拟 MRI 对 GA 率的临床 MRI 的影响。
结果
结果表明，模拟 MRI 的增加最显著地降低了 3 至 8 岁儿童对 GA 的需求。在这个年龄组中，GA 的比例比非模拟 MRI 组低 16.8%（P < 0.05）。
结论
模拟 MRI 减少了儿童对 GA 的需求，对 3 至 8 岁儿童的影响最大。
