Abstract：
Growth monitoring of preterm infants is essential for assessing the nutritional effects on their growth. The current growth monitoring techniques are too stressful, however, for the smallest preterm infants. We performed a systematic review to summarize studies on stress-free techniques for measuring the body size of preterm infants inside incubators other than the traditional calliper and tape measure-based instruments.
We searched four online literature databases: Embase, Medline, Web of Science Core Collection, and Cochrane, using search terms related to patients (neonates, infants, children) and body size measuring techniques. By means of expert judgement we assessed the techniques\' suitability for stress-free body size measurement of an infant lying in an incubator. As a criterion for suitability, we used an imaginary ideal technique.
Twenty-six studies were included in this review. In 24 studies, the technique for body size measurement was related to 3D technology, and the majority of these studies acknowledged clinical superiority of 3D over 2D data. Two 3D techniques were assessed as suitable for stress-free measurement of preterm infants inside incubators. The first technique used a commercially available 3D handheld scanner which needed 3D postprocessing to derive measurement data. The second technique used a self-developed stereoscopic vision system.
3D volumetric parameters have higher clinical value for growth monitoring than 2D. In addition, contactless 3D measurements enable stress-free growth monitoring of even the smallest preterm infants. However, the time-consuming 3D postprocessing challenges the usability of 3D techniques. Regrettably, none of the identified suitable 3D techniques met all our requirements of an ideal all-in-one body size measuring technique for extreme preterm infants. Handheld 3D scanning might have the best properties for developing this ideal technique.

摘要：
早产儿的生长监测对于评估营养对其生长的影响至关重要。目前的增长监测技术压力太大了，然而,最小的早产儿。我们进行了系统的综述，以总结除传统的卡钳和卷尺测量仪器外，用于测量孵化器内早产儿体型的无压力技术的研究。
我们搜索了四个在线文献数据库：Embase，Medline,WebofScience核心合集,还有Cochrane,使用与患者相关的搜索词(新生儿，婴儿,儿童)和体型测量技术。通过专家判断，我们评估了躺在孵化器中的婴儿的无压力体型测量技术的适用性。作为适宜性的标准，我们使用了一种假想的理想技术。
本综述包括26项研究。在24项研究中，人体尺寸测量技术与3D技术有关，这些研究中的大多数都承认3D在临床上优于2D数据。两种3D技术被评估为适用于恒温箱内早产儿的无压力测量。第一种技术使用市售的3D手持式扫描仪，该扫描仪需要3D后处理来得出测量数据。第二种技术使用了自行开发的立体视觉系统。
3D体积参数比2D具有更高的生长监测临床价值。此外,非接触式3D测量能够实现对即使是最小的早产儿的无压力生长监测。然而,耗时的3D后处理挑战了3D技术的可用性。遗憾的是,所有确定的合适的3D技术都不能满足我们对极端早产儿理想的一体化体型测量技术的所有要求.手持3D扫描可能具有开发这种理想技术的最佳特性。
