Although the use of sedation is commonly practiced to keep infants still while receiving magnetic resonance imaging, non-pharmacological strategies are a potential alternative.
The purpose of this study was to determine the success rate of obtaining usable magnetic resonance images in infants with the sole use of non-pharmacological strategies.
Systematic literature review and meta-analysis SETTING: A search was conducted in PubMed, CINAHL and Cochrane Library.
Human infants from birth to 24 months of age who did not receive any sedation or anesthesia during magnetic resonance imaging METHOD: Articles that reported the success rate of obtaining usable images were included.
Of the 521 non-duplicate articles found, 58 articles were included in the systematic review with sample sizes ranging from 2-457, an average success rate of 87.8%, and an average scan time of 30 min. The most common non-pharmacological technique included feeding and swaddling infants before imaging to encourage infants to sleep during the scan. Meta-analysis performed on 53 articles comprising 3,410 infants found a success rate of 87%, but significant heterogeneity was found (I = 98.30%). It was more difficult to obtain usable images solely with non-pharmacological techniques if infants were critically ill or a structural magnetic resonance imaging of the brain was required.
Non-pharmacological techniques are effective for obtaining usable magnetic resonance imaging scans in most but not all infants. Tweetable abstract: Non-pharmacological techniques are effective for obtaining usable magnetic resonance imaging scans in most infants.
尽管在进行磁共振成像检查时，常使用镇静剂使婴儿保持静止，但非药物策略也是一种潜在的替代方法。
本研究旨在确定仅使用非药物策略获得可使用磁共振图像的成功率。
系统文献回顾和荟萃分析
在 PubMed、CINAHL 和 Cochrane Library 中进行检索。
在磁共振成像检查期间未接受任何镇静或麻醉的出生至 24 个月龄的婴儿。
纳入报告获得可使用图像成功率的文章。
在 521 篇非重复文章中，有 58 篇文章纳入系统综述，样本量范围为 2-457 例，平均成功率为 87.8%，平均扫描时间为 30 分钟。最常见的非药物技术包括在成像前给婴儿喂食和包裹，以鼓励婴儿在扫描过程中入睡。对包含 3410 例婴儿的 53 篇文章进行荟萃分析发现成功率为 87%，但存在显著异质性（I = 98.30%）。如果婴儿病重或需要进行脑部结构磁共振成像，则仅使用非药物技术更难获得可使用的图像。
非药物技术在大多数但并非所有婴儿中均有效获得可使用的磁共振成像扫描。
