In hospitals oil based ink is occasionally used to write the patient's name, his room number, and names of the drugs that are used in a mixture on the plastic containers used for infusion. This is done to prevent medication errors. In the current study, the effect of an oil-based ink on the infusion fluid was investigated.Using an oil-based ink containing xylene, letters and other characters were written on an infusion fluid container that was made of Polypropylene·Polyethylene·Ethylene vinyl acetate. It was confirmed that some xylene had been transported to the interior of the container (air phase). Furthermore, the xylene concentration in the air phase rose with repetitive writing and erasing, using the same oil-based ink. But no xylene was dissolved in the solution that was in the container (liquid phase).This observation convinced us that it is highly unlikely that the xylene in the ink can be infused directly into a patient's body. However, to assure the quality of the medication that is in liquid form, it is not desirable for a substance that does not normally exist as a component of the medication to move through its container. In the present experiment, physiological saline was used as a solution (liquid phase). Our findings showed that xylene had a high possibility of dissolving in solutions known for high xylene solubility (e. g., solutions with a large amount of amino acids or surfactants). Therefore, it is necessary to design a method to prevent ink from entering a container when an oil-based ink is applied to the outside of it.

Since 2012, Matsudo City Hospital has increased the number of pharmacists stationed in the ward on weekday mornings at the emergency care center, the intensive care unit (ICU) and the high care unit (HCU). Multidisciplinary joint meetings and joint conferences are conducted in the emergency care center, and patient and drug information is shared. A 20-year-old man was transferred to our hospital after a traffic accident. He was diagnosed with subarachnoid hemorrhage and brain contusion. He exhibited violent movement and intense restlessness. He was sedated with a continuous intravenous infusion of 5 mg/h midazolam and 20 μg/h fentanyl, with intubation. Propofol was also used intermittently. The midazolam infusion was concluded on day 5 of hospitalization. However, his restlessness recurred so an intravenous drip infusion of 150 mg/h haloperidol was administered. On the 7th day, he developed a high-grade fever, muscle rigidity, perspiration, and leukocytosis, and malignant syndrome or malignant hyperthermia was suspected. For malignant syndrome treatment, he received an intravenous drip infusion of 60 mg dantrolene, followed by the combined oral administration of 100 mg/d dantrolene and 7.5 mg/d bromocriptine. Considering various pharmacological effects, we selected an intravenous drip infusion of 25 mg hydroxyzine hydrochloride as the drug to alleviate restlessness. The patient's course continued without recurrence of malignant syndrome; his symptoms improved because of pharmaceutical care with an awareness of patient benefits through clinical and laboratory findings, consultation with the attending physician, presentation of information on causative and therapeutic drugs, and coordinated planning of a prescription design.

In hospitals oil-based ink is occasionally used to write the patient's name, his room number, and names of the drugs that are used in a mixture on the plastic containers used for infusion. This is done to prevent medication errors. In the current study, the effect of an oil-based ink on the infusion fluid was investigated. Using an oil-bused ink containing xylene, letters and other characters were written on an infusion fluid container that was made of Polypropylene・Polyethylene・Ethylene vinyl acetate. It was confirmed that some xylene had been transported to the interior of the container (air phase). Furthermore, the xylene concentration in the air phase rose with repetitive writing and erasing, using the same oil-based ink. But no xylene was dissolved in the solution that was in the container (Iiquid phase). This observation convinced us that it is highly unlikely that the xylene in the ink can be infused directly into a patient's body. However, to assure the quality of the medication that is in liquid form, it is not desirable for a substance that does not normally exist as a component of the medication to move through its container. In the present experiment, physiological saline was used as a solution (liquid phase). Our findings showed that xylene had a high possibility of dissolving in solutions known for high xylene solubility (e.g., solutions with a large amount of amino acids or surfactants). Therefore, it is necessary to design a method to prevent ink from centering a container when an oil-based ink is applied to the outside of it.

The most important aspect of an indwelling inter vascular catheters is to maintain the patency of the catheter. We recently developed a Heparin Lock Flush Solution Kit for use with center vein catheters (only in use at our Hospital). The kit consists of a syringe filled with 9 mL of normal saline (NS) and 1 mL of heparin (1000 IU/mL). We performed the following tests to evaluate the stability, sterility, seal, and dust identification in the preparation. The stability and sterility data indicated that heparin maintained its potency and had no bacterial contamination for 3 months. Testing the seal of the syringe indicated that the seal remained patent at a temperature range of 5°C to 60°C. We also found that even if we sterilized a syringe made of polypropylene using ethylene oxide gas (EOG), no toxins (i.e., ethylene oxide, ethylene chlorohydrin, ethylene glycol) were produced. Next, we examined the preparation time and cost to evaluate the practical benefit of developing the kit. According to our results, the estimated preparation time and cost were 43% and 29% less than for previous methods, respectively. Finally, we put a label on the medicine kit to prevent any misuse by the medical staff.
