Intravenous therapy aims to inject fluids such as medicine or nutritions into the body via vein vessel. This procedure is needed in various cases whether in an ordinary or emergency. Every person has a different difficulty level thus a nurse usually encountered a problem when locating the position of vein vessel. A visualization device that able to work in realtime and have high mobility is really necessary for an emergency situation to speed up the intravenous access. In this study, a stand-alone veins visualization system was developed. The back-projection method that can adjust based on distance was used to speed up the visualization process. The distance between the device and the object is obtained by an ultrasonic distance sensor. The results of this projection method with a flat surface have maximum shift of 0.48 mm. While on various surfaces, projection shifts under 0.9 mm reach 89% from 140 measurement points. Projection shifts that reach more than 0.9 mm occurred due to the sensor readings are on steep curvature or large angles between segments and sensors.

“…Success rate in older age is associated with central vein stenosis or exhaustion of peripheral veins. Sharp et al [24] reported that the male sex was associated with increased vein diameter. Relatively smaller vein diameter in female sex can lead to the possibility of tip malposition.…”

Outcomes of bedside peripherally inserted central catheter placement: a retrospective study at a single institution

Outcomes of bedside peripherally inserted central catheter placement: a retrospective study at a single institution Background: Bedside insertion of peripherally inserted central catheters (PICCs) has higher rates of malposition than fluoroscopic-guided PICC placement. This study evaluated the success rate of bedside PICC placement, variations in tip location, and risk factors for malposition. Methods: This retrospective study included patients who underwent bedside PICC placement from January 2013 to September 2014 in a single institution. The procedure was conducted under ultrasound guidance or by a blind method. After PICC placement, tip location was determined by chest X-ray. Results: The overall venous access success rate with bedside PICC placement was 98.1% (1,302/ 1,327). There was no significant difference in the venous access success rate between ultrasound-guided placement (868/880, 98.6%) and a blind approach placement (434/447, 97.1%). Optimal tip position was achieved on the first attempt in 1,192 cases (91.6%). Repositioning was attempted in 65 patients; 60 PICCs were repositioned at the bedside, two PICCs were repositioned under fluoroscopic guidance, and three PICCs moved to the desired position without intervention. Final optimal tip position after repositioning was achieved in 1,229 (94.4%). In logistic regression analysis, five factors associated with tip malposition included female sex (Exp(B), 1.687; 95% confidence interval [CI], 1.180 to 2.412; P=0.004), older age (Exp(B), 1.026; 95% CI, 1.012 to 1.039; P < 0.001), cancer (Exp(B), 0.650; 95% CI, 0.455 to 0.929; P = 0.018), lung disease (Exp(B), 2.416; 95% CI, 1.592 to 3.666; P < 0.001), and previous catheter insertions (Exp(B), 1.262; 95% CI, 1.126 to 1.414; P < 0.001). Conclusions: Bedside PICC placement without fluoroscopy is effective and safe in central venous catheters. Potential risk factors associated with catheter tip malposition include older age, female sex, cancer, pulmonary disease, and previous central vein catheterizations.

Vessel Health and Preservation: The Right Approach for Vascular Access

“…Generally, the scale in Fig. 2.1 provides a guide for determining the most appropriate catheter for vein size (Sharp et al 2015a(Sharp et al , b, 2016). • Path: Note any aberrancy along the course of the vessel (tortuosity), areas of dilation, or stenosis.…”

Right Assessment and Vein Selection

2019

Right assessment and selection of the best vein and location is the first stage of the vascular access cycle within quadrant 1 of VHP. This stage begins at the time of admission and continues as diagnosis is established and treatment initiated. Most patients receive their first intravenous device during the assessment in the emergency department, typically a PIVC is inserted in a hurried fashion, and location and method of insertion are often not optimal. Once the patient has stabilized, consideration can be given to the most appropriate vascular access device, one that will provide the administration of the prescribed therapy. Assessments of patient history, comorbidities, contraindications, available veins, diagnosis, and duration of therapy are factors that determine level of risk, the appropriate device, and most qualified inserter. Individuals with ultrasound training can apply their skills for assessment and selection of the right location and vein for device insertion.
