Abstract
Preparation of hyperalimentation requires complex process. In order to simplify the process, a basic solution-admixing needle, which was in the stage of development, was used for admixture of commercial basic solutions Paremental-A and-B and amino acid preparations. Study was made on microbial contamination at the time of admixture and on the preparation time. In the experiment carried out at the nurse center of Tokyo Women's Medical College Hospital, the preparation time was as unexpectedly short as about 1 minute and 30 seconds. The hyperalimentation thus prepared was kept aseptic even after storage for 7 to 14 days growth of bacteria and fungi was not observed.
