Perforation of esophagus or stomach is a potential complication during and after insertion of a gastric tube in neonates. The aim of this study was to analyze different types of gastric tubes in a three-dimensional (3D) model of neonatal esophagus and stomach regarding potential perforations.
A 3D model of esophagus and stomach was created based on computed tomography data of a term neonate. Three types of gastric tubes were inserted into the 3D model, the localization was examined by radioscopy and the behavior, stiffness and manageability of each gastric tube was evaluated.
Insertion of gastric tubes with higher stiffness was easier. The rates of correct localization differed significantly between the gastric tubes with the highest rate of correct localization in the softest tube (48.5%) and the lowest rate in the tube with the highest stiffness (21.2%). Additionally, the softest tube showed the lowest rate of localization of its tip at the stomach wall.
The study illustrates differences between various types of gastric tubes regarding stiffness, behavior and resiliency. Softer gastric tubes may be beneficial. These differences may be relevant in neonatal care of very immature and very sick infants.
在新生儿胃管插入过程中和之后，食管或胃穿孔是一种潜在的并发症。本研究的目的是分析在新生儿食管和胃的三维（3D）模型中不同类型的胃管在潜在穿孔方面的情况。
基于一名足月新生儿的计算机断层扫描数据创建了一个食管和胃的 3D 模型。将三种类型的胃管插入 3D 模型中，通过透视检查检查定位情况，并评估每种胃管的行为、刚度和可管理性。
插入刚度较高的胃管更容易。正确定位的比例在最软的管（48.5%）和刚度最高的管（21.2%）之间存在显著差异。此外，最软的管显示其尖端位于胃壁的定位率最低。
该研究说明了不同类型的胃管在刚度、行为和弹性方面的差异。更柔软的胃管可能更有益。这些差异在对非常不成熟和非常生病的婴儿的新生儿护理中可能很重要。
