The Use of Midazolam and Remifentanil During Dialysis Access Procedures

Sedative Adverse ReactionAnalgesic Adverse Reaction5 more

BACKGROUND: Sedation and analgesia are related to unexpected adverse events in chronic renal failure patients undergoing arteriovenous fistula placement procedures under monitored anesthesia care (MAC). OBJECTIVE: Our goal was to investigate and compare the sedation and analgesia related effects and adverse effects of continuous intravenous use of midazolam and intermittent bolus doses of midazolam while intravenous remifentanil is used as a rescue medication in patients with chronic renal failure.

FLEX Vessel Prep Prior to Angioplasty in Native Arteriovenous Fistulae (AVF)

Arteriovenous Fistula Stenosis

A prospective, multi-center, randomized (1:1) clinical study evaluating the FLEX Vessel Prep device plus percutaneous angioplasty (PTA) (study arm) vs PTA alone (control arm) for the treatment of obstructive lesions in the native arteriovenous dialysis fistulae.

An Efficacy and Safety Study of SRM003 in the Treatment of Subjects Undergoing Creation of an Arteriovenous...

Arteriovenous Fistula

A study to evaluate the efficacy of SRM003 treatment versus participating sites' standard practice treatment in improving the rate of AVF maturation and use in subjects with end-stage renal disease undergoing surgery for creation of an AVF to facilitate hemodialysis access. It is hypothesized that when placed outside the blood vessel, the seeded SRM003 gelatin matrix containing endothelial cells can provide a continuous supply of multiple growth regulatory compounds to the underlying cells within the blood vessel, while being protected from the effects of blood flow in the vessel(s) or complications resulting from being in direct contact with the point of injury.

Primary Patency in Post-angioplasty Dysfunctional Arteriovenous Fistula in Renal Dialysis: Paclitaxel-releasing...

Arteriovenous Fistula Renal Dialysis Devices Obstruction

In recent years the use of paclitaxel releasing percutaneous transluminal angioplastic (PTA) balloon catheter is spreading in vascular pathology, mainly in stenosis infrainguinal arteries. This device combined the mechanical action of PTA balloon with the antiproliferative effects of paclitaxel. The use of these devices in venous pathology is limited. This devices could improve the treatment of renal dialysis arteriovenous fistula stenosis.

Vitamin D and Arteriovenous Fistulae

End-stage Renal Disease

Patients requiring hemodialysis following kidney failure need a form of dialysis vascular access in order to undergo the dialysis procedure. Dialysis vascular access dysfunction is an enormous clinical problem. While the best form of vascular access is the arteriovenous fistula (AVF), its primary problem is early, aggressive cellular ingrowth that leads to poor maturation of the vessel, preventing its use for dialysis. Strategies to prevent AVF failure are needed. Vitamin D is a hormone present in all human bodies and is important for good bone formation and immune function. There is new information that links vitamin D to the function of our veins and arteries, which are used in the creation of an arteriovenous fistulae. Our bodies can make vitamin D and can also get vitamin D from our diet. However, a majority of patients with chronic kidney disease and end-stage renal disease (ESRD) have low vitamin D levels (vitamin D deficiency). There are several benefits to correcting low vitamin D levels, however, it is not know whether correcting low vitamin D in the body will lead to better function of the vein and artery used for arteriovenous fistulae creation. The main goal of this pilot study is to examine the role of vitamin D supplementation on AVF maturation and useability for dialysis. Study results will be used to develop larger studies to examine the specific effect that vitamin D supplementation has on the vessels used for AVF creation and whether vitamin D promotes AVF maturation.

Vascular Protective Effect of Rosuvastatin in Arteriovenous Fistula

End-stage Kidney DiseaseDiabetes Mellitus1 more

Background Arteriovenous (AV) fistula is the most common vascular access for long-term hemodialysis in the end-stage renal disease (ESRD) patients. About 25% of these patients are diabetes mellitus. However, the effects of hyperglycemia on the vascular function of arteriovenous fistula are still remained unclear. Studies have shown that blood flow in the AV fistula is significantly reduced in patients with diabetes mellitus. Diabetic patients also require a longer period of time for the maturation of AV fistula, and have slightly higher complication rate than non-diabetic patients. Statins have been widely shown to mediate several important pleiotropic effects in the improvement of vascular endothelial dysfunction, attenuation of inflammatory responses, stabilization of atherosclerotic plaques, inhibition of vascular smooth muscle proliferation, and modulation of procoagulant activity and platelet function.Our experimental studies in diabetic animals demonstrate that administration of a water-soluble statin rosuvastatin significantly improves the fistula flow, vascular function and luminal dilatation of AV fistula in diabetic rats by suppression of vascular oxidative stress and inflammatory load. Study hypothesis The central hypothesis of this research project is rosuvastatin mediates pleiotropic protective effect on vascular endothelial function and suppresses the regional pro-inflammatory reaction in the vasculature, therefore administration of rosuvastatin during the perioperative period of creation of native AV fistulas in diabetic patients with ESRD may potentiate the vascular function and reduce the primary failure rate of AV fistulae.
