Central Vascular access

Clara K Poon, Christopher T Chan
Home hemodialysis (HHD) is emerging as an important alternate renal replacement therapy. Although there are multiple clinical advantages with HHD, concerns surrounding increased risks of infection in this group of patients remain a major barrier to its implementation. In contrast to conventional hemodialysis, infection related complication represents the major morbidity in this mode of renal replacement therapy. Vascular access related infection is an important cause of infection in this population. Use of central vein catheters and buttonhole cannulation in HHD are important modifiable risk factors for HHD associated infection...

OBJECTIVE: To present a simple and affordable model able to properly simulate an ultrasound-guided venous access. DESIGN: The simulation was made using a latex balloon tube filled with water and dye solution implanted in a thawed chicken breast with bones. RESULTS: The presented model allows the simulation of all implant stages of a central catheter. The obtained echogenicity is similar to that observed in human tissue, and the ultrasound identification of the tissues, balloon, needle, wire guide and catheter is feasible and reproducible...

Oxygen delivery to cells is the basic prerequisite of life. Within the human body, an ingenious oxygen delivery system, comprising steps of convection and diffusion from the upper airways via the lungs and the cardiovascular system to the microvascular area, bridges the gap between oxygen in the outside airspace and the interstitial space around the cells. However, the complexity of this evolutionary development makes us prone to pathophysiological problems. While those problems related to respiration and macrohemodynamics have already been successfully addressed by modern medicine, the pathophysiology of the microcirculation is still often a closed book in daily practice...

OBJECTIVES: The common femoral artery is the standard site for immediate vascular access when initiating adult venoarterial extracorporeal membrane oxygenation. However, this approach is fraught with problems such as femoral artery occlusion, distal limb ischemia, reperfusion injury resulting in compartment syndrome, retroperitoneal hemorrhage, thrombosis, embolization, and most importantly, pulmonary edema. Here, we show our preference of using the subclavian artery with a side graft as a different cannulation technique for outflow of extracorporeal membrane oxygenation, which can avoid complications associated with different access techniques...

Central venous access has traditionally been performed on the basis of designated anatomical landmarks. However, due to patients' individual anatomy and vessel pathology and depending on individual operators' skill, this landmark approach is associated with a significant failure rate and complication risk. There is substantial evidence demonstrating significant improvement in effectiveness and safety of vascular access by realtime ultrasound (US)-guidance, as compared to the anatomical landmark-guided approach...

OBJECTIVE: In patients with a high risk of fistula immaturity, we created arteriovenous fistulas (AVFs) combined with brachial artery superficialization. With this procedure, the superficialized arteries are used as drawing routes and the AVFs as returning routes. This is a technical report about AVFs combined with brachial artery superficialization. METHODS: Twenty-four consecutive patients with a high risk of fistula immaturity who underwent AVFs with brachial artery superficialization were included in this single-center retrospective study...

The use of the tunneled central venous catheter (CVC) is steadily increasing worldwide as a means of vascular access for hemodialysis. The increased use of these devices, which often outlive the patients, and the extended time they are used are associated with more frequent complications. Among these, one of the emerging complications is that of the "embedded" or stuck catheter. This term refers to when the catheter cannot be removed after detaching the retention cuff. In medical literature, experiences with the removal of stuck catheters are described with the use of several different methods...

BACKGROUND: Dialysis in elderly patients (>80-years-old) carries a poor prognosis, but little is known about the most effective vascular access method in this age group. An arteriovenous fistula (AVF) is both time-consuming and initially expensive, requiring surgical insertion. A central venous catheter (CVC) is initially a cheaper alternative, but carries a higher risk of infection. We examined whether vascular access affected 1-year and 2-year mortality in elderly patients commencing haemodialysis...

As a consequence of the central role of the arteriovenous fistula for dialysis (AVF) in the clinical management of the dialysis patient the necessity to limit the puncture-related complications to extend as much as possible the life of the vascular access. Accordingly, the AVF needling technique has gained growing attention. Alongside the traditional rope ladder (RL) puncture method, the buttonhole technique (BH) is increasingly popular; this technique employs the same cannulation sites of AVF in every dialysis associated with the use of dull needles to minimize vessels damage...

INTRODUCTION: Aerobic bacterial infections often complicate vascular access in patients receiving haemodialysis, leading to Catheter-Related Blood Stream Infections (CRBSI). Various studies report Gram - positive bacteria, Staphylococcus aureus (S. aureus) in particular, as the most common aetiologic agent. Studies on microbiological analysis in this subset of population from India are very few. AIM: To examine clinical and bacteriological profiles of haemodialysis patients developing CRBSI, the antibiotic susceptibility of the bacteria isolated from these patients and determine nasal carriage of S...

BACKGROUND: The majority of reports regarding general vascular access choices for apheresis procedures argue that peripheral venous access should be considered first. However, the clinical reality appears to be different. While some procedures mandate central vascular access (e.g., therapeutic apheresis procedures in critically ill patients) and in some cases it is the patient's preference, we propose that the majority of elective procedures can be successfully performed peripherally...

BACKGROUND: Central venous catheters (CVC) are the only option when hemodialysis is needed for patients without definitive vascular access. However, CVC is associated with complications, such as infection, thrombosis, and dysfunction, leading to higher mortality and expenditures. The aim of this study was to compare the effectiveness of 30 % trisodium citrate (TSC30 %) with heparin as CVC lock solutions in preventing catheter-related bloodstream infections (CRBSI) and dysfunction in hemodialysis patients...

BACKGROUND: Intradialytic hypotension (IDH) has a dramatic impact on the main outcomes of dialysis patients. Early warning of hemodynamic worsening during dialysis would enable preventive measures to be taken. Blood oxygen saturation (SO2) is used for hemodynamic monitoring in the critical care setting and may provide useful information about IDH onset. AIM: To evaluate whether short- and medium-term variations in the SO2 signal (ST-SO2var, MT-SO2var,) during dialysis are a predictor of IDH...

AIM: We aimed to describe the clinical epidemiology of Staphylococcus aureus bacteraemia (SAB) at a large, tertiary/quaternary children's hospital in Australia. METHODS: We performed a retrospective chart review of SAB cases at the Children's Hospital at Westmead (CHW) over 5 years; 2006-2011. We compared frequency, clinical profile and outcomes of SAB with published data from CHW; 1994-1998. We compared health-care associated with community-associated (HCA-SAB and CA-SAB; defined epidemiologically) and methicillin-resistant with methicillin susceptible S...

STUDY OBJECTIVE: Historically, the placement of internal jugular central venous lines has been accomplished by using external landmarks to help identify target-rich locations in order to steer clear of dangerous structures. This paradigm is largely being displaced, as ultrasound has become routine practice, raising new considerations regarding target locations and risk mitigation. Most human anatomy texts depict the internal jugular vein as a straight columnar structure that exits the cranial vault the same size that it enters the thoracic cavity...
