已经开发了用于大鼠慢性静脉喂养的设备、技术和解决方案。通过使用特殊的安全带和输液旋转组件，140- 250-gm的无限制大鼠可以一次仅通过静脉喂养数周，从而延长代谢和营养研究的时间。配制了含有必需矿物质和维生素的32%葡萄糖和5%氨基酸溶液，用于静脉喂养方案。该模型操作简便，对研究外科营养与代谢相关问题具有重要的应用价值。
Equipment, techniques, and solutions have been developed for the chronic intravenous feeding of rats. With use of a special harness and fluid infusion swivel assembly, 140- to 250-gm, unrestrained rats can be fed for weeks at a time exclusively by vein, allowing for prolonged periods of metabolic and nutritional study. A 32% dextrose and 5% amino acid solution containing essential minerals and vitamins was formulated for the intravenous feeding regimen. This model can be readily utilized and has great potential value for studying problems related to surgical nutrition and metabolism.
