There is a myriad of factors that can lead to temperature derangements in anesthetized children undergoing magnetic resonance imaging (MRI). Temperature abnormalities in pediatric patients are associated with increased morbidity and mortality. Although some reports have looked at this topic, to our knowledge, no studies have continuously monitored temperature throughout the MRI scan. The purpose of this study is to determine the impact of MRI on body temperature for anesthetized children undergoing MRI using continuous temperature measurement, identify patient risk factors to develop temperature abnormalities, and determine the effect of temperature derangements on perianesthetic complications.
This retrospective, single-center study evaluated 285 pediatric outpatients from January 1, 2018, to March 31, 2018, who were less than 8 years old and underwent anesthesia for an MRI scan. Temperature, postanesthesia care unit length of stay, and demographic data were collected retrospectively using chart review and data extraction from electronic medical records. Statistical analyses included unpaired test, chi-square test, and simple and multiple linear regressions.
Sixty-three percent (179/285) of children in our study had a median temperature less than 36°C during their MRI scan. There were no patients who had a median temperature greater than 38°C during their MRI scan. There were no identifiable patient risk factors for the development of hypothermia. Those who developed hypothermia did not have an increased rate of perianesthetic complications.
MRI in anesthetized children is associated with hypothermia but does not correlate with any significant perianesthetic complications.
在接受磁共振成像（MRI）检查的麻醉儿童中，有无数因素可导致体温紊乱。儿科患者的体温异常与发病率和死亡率增加相关。尽管有一些报告探讨了这个话题，但据我们所知，尚无研究在整个MRI扫描过程中持续监测体温。本研究的目的是通过连续体温测量来确定MRI对接受MRI检查的麻醉儿童体温的影响，识别发生体温异常的患者风险因素，并确定体温紊乱对围麻醉期并发症的影响。
这项回顾性单中心研究评估了2018年1月1日至2018年3月31日期间285名年龄小于8岁且接受MRI扫描麻醉的儿科门诊患者。通过病历审查和从电子病历中提取数据，回顾性收集体温、麻醉后护理单元住院时间和人口统计学数据。统计分析包括非配对t检验、卡方检验以及简单和多元线性回归。
在我们的研究中，63%（179/285）的儿童在MRI扫描期间体温中位数低于36°C。在MRI扫描期间，没有患者体温中位数高于38°C。没有可识别的发生体温过低的患者风险因素。发生体温过低的患者围麻醉期并发症发生率没有增加。
麻醉儿童进行MRI检查与体温过低相关，但与任何严重的围麻醉期并发症无关。
