Purpose: This study was conducted to examine the effect of simulation-based training on the clinical competence and confidence of nursing students in intravenous injection performance and the satisfaction of clients. Methods: This study employed a randomized control posttest non-synchronized design. The participants were 90 second-year nursing students(31 multimedia group, 28 IV model group, 31 IV computerized systems group) of S-University in Seoul, Korea. Each group was given 30 minutes for five trial injections, then the students performed intravenous injections on the back of hands of the clients, and the results were measured. Results: There were significant differences in competence of clinical performance among the three groups showed no significant differences in confidence before and after intravenous injections. While there was no significant difference in the satisfaction of clients among the three groups, there were significant differences in the satisfaction of clients resulting from the success or failure of intravenous injections(p=<.001). Conclusion: This study shows that simulation-base training contributes to the enhancement of competence and confidence of nursing students in clinical performance. It would be helpful to use various simulation-based training media as another choice of education in different fields.

This paper is about developing an intravenous injection management system that can provide nurses with information related to intravenous injection in real-time to compensate for possible instability factors during intravenous injection. The intravenous injection management system consists of an app-based user S/W and a web-based administrator S/W. User S/W is implemented to provide users with the ability to identify patients who need intravenous injection through smartphones, tablet PCs, and nursing PDAs, recognize information codes given to patients, and enter and share treatment contents and treatment items after intravenous injection. As a result of intravenous injection treatment uploaded through the user app, the manager S/W can check the records of intravenous injection treatment items, perform user management functions, emergency notification registration and management functions, and data upload functions. The implemented system has not yet been tested on the EMR system used in the actual hospital. Therefore, through further research, S/W will be optimized and actual environmental application tests will be conducted through cooperation with hospitals.

Intravenous injection is widely used for patient treatment, including injection drugs, fluids, parenteral nutrition, and blood products, and is the most frequently performed invasive treatment for inpatients, including blood collection, peripheral catheter insertion, and other IV therapy, and more than 1 billion cases per year. Intravenous injection is one of the difficult procedures performed only by experienced nurses who have been trained in intravenous injection, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Nurses who frequently perform intravenous injections may also make mistakes because it is not easy to detect veins due to factors such as obesity, skin color, and age. Accordingly, studies on auxiliary equipment capable of visualizing the venous structure of the back of the hand or arm have been published to reduce mistakes during intravenous injection. This paper is about the development of venous detection equipment that visualizes venous structure during intravenous injection, and the optimal combination was selected by comparing the brightness of acquired images according to the combination of near-infrared (NIR) LED and Filter with different wavelength bands. In addition, an image processing algorithm was derived to threshehold and making blood vessel part to green through grayscale conversion, histogram equilzation, and sharpening filters for clarity of vein images obtained through the implemented venous detection experimental module.

This study was attempted to identify the perception and experience of hospital nurses on medication errors of high-risk intravenous drugs, and to identify the causes of medication errors and ways to improve them. The subjects of the study were nurses with work experience related to high-risk intravenous administration working at a university hospital located in D City, and data were collected between May 16 ~ 30, 2021. As a result of the study, six key factors were identified as the key factors in the safety of high-risk intravenous injections: the lack of a protocol for the administration of major drugs in each ward, the lack of training in the operation of the injection machine, the lack of standardized procedures for administering high-risk intravenous injections, the lack of individualized medication training for nurses, the lack or lack of the hospital's own drug list, and the lack of identification of drugs packaged in similar containers. At the nursing practice level, it is proposed to apply a high-risk intravenous medication safety program and conduct a future study to identify safety outcome indicators.

Intravenous injection is the most frequent invasive treatment for inpatients and is widely used for parenteral nutrition administration and blood products, and more than 1 billion procedures are used for peripheral catheter insertion, blood collection, and other IV therapy per year. Intravenous injection is one of the difficult procedures to be performed only by trained nurses with intravenous injection training, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Accordingly, studies on auxiliary equipment capable of visualizing the vein structure of the back of the hand or arm are being published to reduce errors during intravenous injection. This study is a study on the performance difference according to the number of LEDs irradiating the 850nm wavelength band on a vein detector that visualizes the vein during intravenous injection. Four LED PCBs were produced by attaching NIR filters to CCD and CMOS camera lenses irradiated on the skin to acquire images, sharpen the acquired images using image processing algorithms, and project the sharpened images onto the skin. After that, each PCB was attached to the front end of the vein detector to detect the vein image and create a performance comparison questionnaire based on the vein image obtained for performance evaluation. The survey was conducted on 20 nurses working at K Hospital.

The aim of the present study was to elucidate the effect of the water soluble chitosans on the removal of contaminated radiostrontium (Sr-85) from the bone of mice. The remaining radioactivities in intravenously injected controls(group 1) were higher than in intraperitoneally injected controls (group 4, P<0.01). The % retention at day 5 were $57.7{\pm}1.9%,\;54.4{\pm}1.2%$, respectively. Single intravenous injection of 0.3% water soluble chitosan and continuous oral ingestion of 10% water soluble chitosan for 15 days were' ineffective on the removal of contaminated radiostrontiums. Multiple intravenous or intraperitoneal injections of water soluble chitosan effectively removed contaminated radiostrontiums(P<0.01 vs controls). In conclusion, water soluble chitosan might remove once incorporated radiostrontium from bones of mice. Further studies were needed to elucidate the mechanism of the removal.

The purpose of this study is to compare the effects on nursing students' knowledge, performance confidence, and skills from combined virtual IV simulator and mannequin arm IV cannulation training against training with a mannequin arm only. A non-equivalent control group pretest-posttest experimental study was carried out. Ninety-three sophomore nursing students who were just beginning their fundamental skills training were recruited. Participants were divided into two groups (46 for the combined group and 47 for the mannequin-only group). Data were collected from March 18-29. For the experimental group, both virtual IV simulator and mannequin-arm training were provided for 30 minutes (15 minutes each). For the control group, training for 30 minutes with a mannequin arm only was provided. After intervention, there was no statistically significant difference in the knowledge score between the two groups (F=2.52, p=.116). However, there was a significant improvement in performance confidence (t=2.14, p=.035) and nursing skills (t=5.34, p<.001) in the experimental group, compared with the control. Overall, this study provides empirical evidence that the combination of virtual IV simulator and mannequin arm training may further enhance nursing students' performance confidence and nursing skills.

Purpose: The purpose of this study was to examine the effects of structured nursing intervention for caregivers on maintenance of intravenous (IV) infusions in infants. Methods: The structured nursing intervention was developed through the processes of interviews with nurses from pediatric wards. To identify the effects of the developed nursing intervention, a non-synchronized non-equivalent control group pretest-posttest design study was conducted with caregivers from the pediatric ward from a hospital in Seoul. Of 100 admitted infants, 50 caregivers were assigned to the intervention group and received the structured nursing intervention for maintenance of intravenous infusions in infants. The others were assigned control group and received routine care. Data were collected on patient factors, IV insertion factors, treatments, and IV related complications. The form developed for the structured nursing intervention was used by staff nurses. Results: Compared to the control group, IV insertion frequency in experimental group infants was significantly lower and IV related complications decreased (p<.05). Conclusion: These results suggest that the structured nursing intervention for caregivers on maintenance of intravenous infusions may have effects on maintenance of intravenous infusions in infants, and decreasing IV related complications. This nursing intervention can be used to improve IV related problems of admitted infants.
