Chlorhexidine Caps for CLABSI Prevention in Hemodialysis: a Pilot Randomized Controlled Trial

The goal of this clinical trial is to compare a chlorhexidine antimicrobial barrier cap in patients requiring hemodialysis treatment to the standard hemodialysis caps currently used within the Metro North Kidney Health Service. The main questions to answer are: * Study Feasibility * Occurrence of infectious complications related to renal central venous catheters Participants will be randomly allocated to receive either of the below hemodialysis caps to cover their hemodialysis catheter hub: * The standard hemodialysis cap used at the Royal Brisbane and Women's Hospital, or * The intervention hemodialysis cap containing chlorhexidine inside it Researchers will compare standard and chlorhexidine hemodialysis caps to see if the presence of chlorhexidine improves the occurrance of infectious complications related to the hemodialysis catheter.

SAVE-FistulaS: the SelfWrap-Assisted ArterioVEnous Fistulas Study

This is a prospective, randomized, multi-center clinical trial for chronic kidney disease (CKD) patients referred for creation of a new arteriovenous fistula (AVF) in order to assess the safety and effectiveness of SelfWrap, a bioabsorbable perivascular wrap.

Single-Needle Distal Return for Long-Term Arteriovenous Fistula Care

Background: For millions of people worldwide with kidney failure, a well-functioning vascular access, like an arteriovenous fistula (AVF), is essential for life-sustaining hemodialysis. However, the standard method requires puncturing the same AVF with two needles three times a week, which over time can damage the vessel, leading to scarring, narrowing, and frequent failures. These complications often require repeated surgical or minimally invasive procedures (reinterventions), causing significant pain, high medical costs, and exhaustion of the patient's limited blood vessels. New Approach: This study will evaluate a modified puncture technique called the Single-Needle Distal Return (SNDR) strategy for long-term AVF care. Instead of using two needles in the AVF, only one needle is placed in the AVF to draw blood. The cleaned blood is then returned to the body through a second needle placed in a superficial vein in the foot or lower leg. This approach aims to reduce trauma to the critical AVF. Study Plan: This is a clinical study conducted at the Blood Purification Center of Anhui Medical University Affiliated Suzhou Hospital. We plan to enroll approximately 50 adult hemodialysis patients who use an AVF and are willing to try the SNDR technique. For comparison, we will also observe data from a similar number of patients receiving standard two-needle AVF care during the same period. The study will last about three years. We will closely monitor patients using the SNDR technique to assess: Effectiveness: Whether dialysis remains adequate (measured by Kt/V). Safety: Rates of complications (like bruising or infection), dialysis machine alarms, and venous pressure during treatment. Practical Benefits: Whether it reduces the need for repair procedures (reinterventions) and hospitalizations related to the AVF. Economic Impact: Changes in healthcare costs. Patient Experience: Patient tolerance and comfort with the technique. We will also analyze the characteristics of patients who successfully use this technique long-term to help identify who might benefit most from it in the future. Potential Significance: If proven successful and safe for long-term use, the SNDR strategy could help protect a patient's precious AVF, potentially reducing painful procedures, lowering costs, slowing down the exhaustion of blood vessels, and improving the quality of life for people on long-term dialysis. The findings may also guide better planning for vascular access care.

Time to Ambulation After ProGlide Closure

Transradial access has become the standard for coronary procedures due to fewer vascular complications and shorter bed rest, yet transfemoral access remains essential for complex peripheral interventions requiring larger sheaths and stronger support. Vascular closure devices (VCDs), particularly suture-mediated devices such as ProGlide, have improved femoral access by reducing hemostasis time, ambulation delay, and patient discomfort. Although early ambulation after ProGlide closure has been reported, current practice varies widely, and the relationship between ambulation timing and vascular complications remains unclear. This trial aims to evaluate the effect of different ambulation times after ProGlide closure in transfemoral peripheral angiography or intervention, with the goal of identifying the optimal time to ambulation that balances safety and efficiency.

Autologous Adipose Derived Mesenchymal Stem Cells (AMSC) in Reducing Hemodialysis Arteriovenous Fistula Failure

The aim of this phase 1 study is to determine the role of autologous adipose derived mesenchymal stem cells in the reduction of hemodialysis arteriovenous fistula failure when applied during the time of surgical creation.

Access Cannulation Trial II

This is a pivotal, interventional, prospective, single-arm, open-label, multi-site clinical investigation intended to support FDA clearance of the study device based on the safety and efficacy of the device in cannulating arteriovenous fistulas (AVFs) for hemodialysis procedures.

Optimizing Access Surgery In Senior Hemodialysis Patients

The number of elderly hemodialysis patients is growing. Vascular access complications are a major determinant of the quality of life and health care costs for these vulnerable patients. The three different types of vascular access, i.e. autologous arteriovenous fistulas, arteriovenous grafts, and central venous catheters, have never been compared in randomized controlled trials. This project will deliver the much-needed evidence to determine the optimal strategy for vascular access creation in elderly hemodialysis patients in order to deliver better health care at lower costs.

Reduction of Complications Associated With PICC Management

The present study aims to analyze different care routes of the peripheral access central venous catheter to assess which alternative allows a moderate reduction in the level of complications associated with prolonged care frequency, due to the reduction of device manipulation. A high level of patient satisfaction is detected due to the controlled follow-up of the device care, as well as a decrease in the need for transfer to a center for follow-up. Objective: Identify the type of care frequency for PIVCs most beneficial for the reduction of complications associated with extraluminal device care (thrombosis, phlebitis, accidental removal, obstruction).

Novel Medical Device for Pharmacological Therapy

Background: Different co-creation methods were used to design and prototype a new fixative device for multiple intravenous therapies with the ability to control and identify the pharmacological therapy administered to a patient. Objectives: To validate a newly created device for the reduction of complications related to the use of intravenous therapy Methods: A multidisciplinary team composed of eight professionals specializing in the field of critical care and an engineering professional in industrial design was responsible for collecting, evaluating, and materializing the ideas and needs arising from clinical practice in a device that met the standards of the same.

Radial Vs. State-Of-The-Art Femoral Access for Bleeding and Access Site Complication Reduction in Cardiac Catheterization (REBIRTH)

This is a phase IV, prospective, open label, randomized-controlled study that will compare radial access with state-of-the-art femoral access in patients without ST-segment elevation acute myocardial infarction undergoing cardiac catheterization. Subjects will be randomized 1:1 into 2 treatment groups: radial access and state-of-the-art femoral access. Randomization will be performed in blocks of 50 per site. Similarly, a second sub-randomization will be performed in the femoral access group into use of 18 vs 21 gauge needles, also in a 1:1 fashion.

Microorganisms on Reusable Tourniquets

The purpose of this study was to compare microbial contamination on the surface of reusable stasis after indefinite use, 2 weeks and 4 weeks. We investigated how the site - the operating theater and the emergency department, as well as the time of use - affects the number of organisms.

Comparison of Three Types of Distal Arteriovenous Fistulas: SBAVF, RCAVF, and RCAVF With Venous Branch Patch.

This study aims to determine which type of distal arteriovenous fistula (SBAVF, RCAVF, and RCAVF with venous branch patch) is most clinically favorable. The recommendations and scientific evidence do not suggest which option should be chosen initially. The investigators expect that results will show which type of the anastomosis should be preferred.
