An improved system for preparing total parenteral nutrient (TPN) solutions is described. The new system uses a personal computer, a three-station volumetric pump, and empty polyvinyl chloride (PVC) containers. The computer's order-entry screen facilitates data entry by displaying a format similar to the physician's order sheet. After calculating the volumes of i.v. solutions and additives and the total cost of the TPN solution, the computer prints labels containing this information. Using the volumetric pump, the required volumes of crystalline amino acids, dextrose injection, and sterile water for injection are added simultaneously to either one-liter or three-liter PVC containers. Each bag contains the patient's entire daily TPN requirements. Approximately 30 liters of TPN solution are prepared daily by specially trained technicians in a centralized i.v. room. Compared with the previous method of preparing TPN solutions using evacuated one-liter glass bottles, the average time required to prepare and determine the cost of each patient's TPN solutions has decreased from 35 to 21 minutes daily. Total savings resulting from reduced materials and labor costs is approximately $28,240 annually. The new system for preparing TPN solutions is efficient and cost effective.
本文描述了一种改进的全胃肠外营养（TPN）溶液制备系统。新系统使用个人计算机、三站式容量泵和空的聚氯乙烯（PVC）容器。计算机的医嘱录入屏幕通过显示类似于医生医嘱单的格式来方便数据录入。在计算静脉输液溶液和添加剂的体积以及TPN溶液的总成本后，计算机打印出包含这些信息的标签。使用容量泵，将所需体积的结晶氨基酸、葡萄糖注射液和注射用水同时添加到一升或三升的PVC容器中。每个袋子包含患者一天所需的全部TPN。经过专门培训的技术人员每天在集中的静脉输液室中制备约30升TPN溶液。与以前使用抽空的一升玻璃瓶制备TPN溶液的方法相比，制备并确定每位患者TPN溶液成本所需的平均时间从每天35分钟减少到了21分钟。由于材料和劳动力成本降低而带来的年度总节省约为28,240美元。新的TPN溶液制备系统高效且具有成本效益。
