Regarding the management of blood preparations, since September 1995 the Ministry of Heath, Labour and Welfare has had to make and/or to keep documentary records such as the product name, date of dispensing, the patient's name and lot number and so on. At Yamanashi Medical University Hospital, to cope with deleterious accidents caused by blood preparations, we developed a new system for the management of blood preparations. This system consists of a printing system for confirmation labels for blood prescriptions and a computerized management system concerning the medication. In this study, the effect of this new management system on the rational use of blood preparations was evaluated. Compared with the former system, the time required to dispense blood preparations decreased from about 500 to 170 seconds per case. Furthermore, based on a questionnaire to medical doctors and/or nurses, it appeared that this system could reduce the time required to manage blood preparations and improve the rational use of injectable drugs.

The stability of powdery dosage forms of drugs prepared by unsealing the packages was investigated. For 247 articles purchased by the Yamanashi Medical University Hospital, the variables related to the evaluation of stability after unsealing these packages and investigating the contents based of an “Interview Form”. A longterm preservation test was carried out on 153 items (94%), and the mean length of the test was about 36 months. The acceleration and the severity tests were carried out using 17 items (10.4%) and 114 items (69.9%), respectively. The mean conditions of the acceleration test was 40°C/6 months, which agreed with the guidelines proposed by the “Drug Manufacturing Guidelines”. On the other hand, for the severity test, certain conditions for the evaluation could not be arranged, and testing was carried out under various conditions. In order to improve the efficiency of dispensing and the quality of life for patients, a further increased standardization of the testing conditions is recommended.

Di-2-ethylhexyl Phthalate (DEHP) was reported to dissolve from a polyvinyl chloride (PVC) administration tube during the infusion of an injection fluid containing a solvilizing agent, soybean oil or lecithin, etc. This paper describes the behavior of DEHP dissolution from PVC tubes during enteral tube feeding. The DEHP concentration was determined using HPLC. After the passage the ENSURE LIQUID® (EL) solution through the PVC tube, DEHP was dissolved in the EL solution. The EL solution is one type of enteral nutrition. This dissolution pattern was similar to that of injection fluid containing a solvilizing agent, in which the DEHP concentration in the EL solution increased linearly over time at first and thereafter reached a plateau. 170 μg of the DEHP was dissolved after 200mL of the EL solution had passed through the PVC administration set (the drip conditions were 25°C, 100mL/hr, tube length 115cm and inner diameter 0.3cm). The amount of DEHP which dissolved into the solution depended on the temperature (25-40°C), and no clear difference was observed between the PVC tubes (administration tube, feeding tube). In addition, the amount of DEHP that dissolved into the solution varied depending on the type of enteral nutrition.
