Intravenous (IV) infusion of medical fluid is a very common procedure used as part of medical procedure treatment. It is also the best alternative medical administration route when medical administration through orally is impossible. The most common use of VAD is the short Peripheral IV Catheter (PIVC) or recognized as IV Cannula. In spite of that, even with experience used of PIVC in medical practice nowadays the rate of IV access failure is very high which is up to 69%. Intensive research studies shows the dislodgement case is one of the major contributions of PIVC failure. For some reason only a fewer cases are reported to the administration. This article seeks the awareness and risk factor regarding to the prevailing IV access failure using the PIVC. This manuscript reviewed the statistical data of PIVC dislodgement, significant of dislodgement, dislodgment cases among pediatric, medical staff factor related to PIVC dislodgement and alternative of securement device. This manuscript also discussed the needs of new securement device in order to reduce the percentage of PIVC dislodgement from occurs.
Introduction: In this study, Renal artery (RA) stenosis of Single Stenosed (SS) and Double Stenosed (DS) with the condition of Normal Blood Pressure (NBP) and High Blood Pressure (HBP) were investigated using the aid of Fluid Structure Interaction (FSI) approach. Methods: Numerical analysis of 3D model patient’s specific abdominal aorta with RA stenosis was conducted using FSI solver in software ANSYS 18. Results: The results of velocity profile, pres- sure drop, time average wall shear stress (TAWSS), Oscillatory shear index (OSI) and total deformation of SS and DS with the condition of NBP and HBP were compared in terms of blood flow and structural wall tissue behaviour. The results concluded SS-NBP produced the highest value of velocity profile, TAWSS and OSI parameter compared to the others. Meanwhile, SS-HBP indicates the highest value pressure drop. On the other hand, SS-HBP and DS-HBP have a higher distribution of deformation contour and also maximum VMS compared to SS-NBP and DS-HBP. Conclusion: With the aid of FSI approach, this studied has proven that the existence of SS at RA location has a higher impact on the velocity magnitude, higher pressure drop, higher TAWSS and OSI value compared to the DS case. This is due to a high concentration of pressure acting at the narrow blood vessel of SS compared to DS cases which most of the blood flow will pass to the lower part of abdominal aorta.
