We aim to assess the effect of regional block anesthesia on vein diameter, type of AVF placement, and fistula size and flow volume. ⋯ Vein diameter increases significantly in the basilic and cephalic veins following regional block anesthesia and may improve the rate of native fistula placement. Propensity to dilate after regional block anesthesia does not predict size of the fistula.

Randomized Controlled Trial Comparative Study
Comparison between local and regional anesthesia in arteriovenous fistula creation.
Assessment of the effectiveness of brachial plexus block (BPB) via axillary approach compared to regional anesthesia for arteriovenous fistula surgery in patients affected by end-stage renal disease. ⋯ The axillary-approached BPB was more advantageous than local anesthesia. Its effectiveness was because of venous dilation and the decrease in the PI, consequent to the reduction in peripheral resistances and the increase in local blood flow, thus offering an ideal background for fistula creation and short-term patency.

Although increased infectious and thrombotic complications have been reported in patients with human immunodeficiency virus (HIV), little is known regarding hemodialysis catheter-related complications in HIV patients. In this report, we reviewed our experience and complication rates for tunneled cuffed catheters (TCCs) in HIV patients requiring hemodialysis. ⋯ TCCs are associated with an increased risk of infection in HIV patients requiring hemodialysis. Moreover, HIV infection is associated with an increased risk of mortality among hemodialysis patients. Hypoalbuminemia, history of intravenous drug use, and low CD4+ lymphocyte counts are associated with increased risk of catheter infection in HIV patients requiring hemodialysis.

Infections are a major complication of the use of hemodialysis central venous catheters. In our study we evaluated the efficacy of the hemodialysis central venous catheter protocol management adopted in our center, through a retrospective analysis of all hemodialysis central venous catheters inserted over a period of 6 years. ⋯ Our experience confirms, in a 72-month follow-up, the importance of careful central venous catheter management as a crucial feature in reducing the incidence of infective events in patients with central venous catheters in dialytic treatment.

In dialysis patients, both central venous catheter (CVC) insertion and CVC use during the dialysis procedure pose important legal issues, because of potentially severe, even fatal, complications. The first issue is the decision of the kind of vascular access that should be proposed to patients: an arteriovenous (AV) fistula, a graft, or a CVC. The second issue, when choosing the CVC option, is the choice of CVC: nontunneled versus tunneled. ⋯ These are theoretically expected as pure complications (and not as malpractice effects), but legal issues might relate to inappropriate catheter care (in both the inpatient and outpatient settings) rather than to the event per se. Thus, in the individual case it is indeed very difficult to establish malpractice and liability with a catheter-related infection or thrombosis. In conclusion, we cannot avoid complications completely when using CVCs, but reducing them to a minimum and adopting safe approaches to their insertion and use will reduce legal liability.
