Filter by:The primary study objective is to evaluate the benefit of the Sirolimus eluting Collagen implant (SeCI; Sirogen), a single dose prophylactic treatment delivered intraoperatively at the time of surgical creation of an arteriovenous fistula for hemodialysis vascular access.
Cannulation of complex arteriovenous fistula (AVF) or graft (AVG) is a challenge to renal nurses. Ultrasound (US) guidance on central and peripheral venous access visualisation has been widely adopted in nephrology and shown to reduce complications of vascular interventions. With broader adoption of handheld US devices in clinical services, renal nurses could acquire this point-of-care technique to increase the successful cannulation rate while facilitating confidence build-up during training and practice. We aim to evaluate the use of handheld US on difficult AVF/AVG cannulation in a hospital-based dialysis unit.
The aim of this non-inferiority trial is to determine if the distal radial access (DRA) during percutaneous coronary intervention (PCI) has an acceptable efficacy compared to the reference access through the conventional radial artery (TRA) with a lower rate of radial artery occlusion (RAO) in real life practice.
This study aimed to determine the accuracy of the V technique in predicting the location of the femoral vein compared to the technique of palpating the femoral artery with the use of USGss as a standard in determining the exact location of the femoral vein.
Every patient need venous access for surgery under anesthesia. It is the most frequently performed invasive procedure in medicine in the whole world. In expert groups, ultrasonographically guided vascular access (UGVA) appears to be a significantly better method, but studies on larger groups of patients are lacking. Prospective randomized 2-arm study which is comparing success rate of ultrasound guided a palpation inserted cannulas in patients undergoing primary hip or knee arthroplasty. The project will be managed according to the protocol of principles of Good Clinical Practice and valid regulations.
Chronic kidney disease (CKD) is one of the leading health problems imbibing a major portion of health budget worldwide. The global prevalence of CKD is estimated to be 13.4% with approximately 5 to 7 million people needing renal replacement therapy. There is lack of epidemiological surveys regarding CKD but it is estimated to be around 5% and nearly half of them are diabetic. In Pakistan most of the patients undergo hemodialysis as mode of renal replacement as renal transplant centers are few and over burdened. Therefore, a good vascular access for hemodialysis is vital for CKD patients. A functioning arterio-venous fistula (AVF) improves quality of life and morbidity. However, access failure remains a major problem in patients of CKD accounting for third most common cause of admission. There are various options for attaining vascular access but AVF remains the most reliable with less morbidity and better overall patency rate. However, the AVF has its own limitation and has overall patency rate of 50-70% at 1 year and 30-40% at 2 years. This outcome indicates that strategies to prevent occlusion by altering modifiable risk factors are suboptimal and warrant further research. Patients of CKD often have associated cardiovascular diseases as Ischemic heart disease, left ventricular failure and angina. They are often taking cardio-protective medicines as antiplatelets, angiotensin converting enzymes and calcium channel blockers. Intimal hyperplasia has been shown to be the most important cause of AVF failures.2 Angiotensin II promotes vascular smooth muscle proliferation through various growth factors. Various experimental models have clearly depicted that ACE inhibitors effectively stop smooth muscle growth and intimal hyperplasia in vessel walls. Literature review shows conflicting results in terms of AVF patency when ACE inhibitors are used in conjunction. A study by Jackson RS and colleagues showed that ACE inhibitor were associated with reduced hazard ratio [HR], 0.35; 95% confidence interval [CI], 0.16-0.76; P = .008). Whereas, another study showed no role of ACE inhibitors in preventing graft failure. The possible explanation can be study designs as most studies were retrospective and effects of possible confounders. Moreover, there is lack of research in Pakistan to see the effects of pharmacological drugs on primary patency of AVF among CKD patients. The rationale of this study is to effectively establish the role of ACE inhibitors in achieving primary patency of AV fistulas while reducing the number of confounders. This will be the first randomized controlled trial conducted in Pakistan. The primary outcome is AVF patency at one year. Secondary outcomes will include graft complications and graft maturation time after surgery.
Single center, randomized trial (1:1 fashion) to asses the safety and the feasibility of the ultrasound guided venous puncture vs standard fluoroscopic technique in patients undergoing pacemaker or implantable cardioverter-defibrillator implantations.
Researchers are evaluating the clinical efficiency of utilization of a dual-plane simultaneous view ultrasound probe (Butterfly iQ+; Butterfly Network, Inc.) during arterial catheter placement in the operating room
The aims of this study are to: - Determine the AVF (arteriovenous fistula) survival of patients submitted to MuST compared to those submitted to RL (rope-ladder). - Determine the AVF (arteriovenous fistula) complication rate of patients submitted to MuST compared to those submitted to RL (rope-ladder). - Analyze the intensity of pain perceived by the patient with each cannulation technique under study.
