Filter by:All participants in this clinical trial will be undergoing surgery and will have a central venous catheter (also known as a central line) placed in the large vein in the neck as part of their routine care. The purpose of this clinical trial is to compare different ways of dressing central lines. In current standard care, central lines are stitched in place and covered with a protective transparent dressing. This standard care will be compared with the addition of a haemostatic powder beneath the transparent dressing. This powder product aids clotting at the level of the skin, meaning that it prevents or reduces bleeding while helping to maintain a dry and protected environment. The main questions this clinical trial aims to answer are: - Will the addition of a haemostatic powder increase the durability of central line dressings? - What proportion of dressings required an unplanned change? - The reason(s) for any unplanned change - The incidence of bleeding around central line insertion sites - Were any skin problems observed once the dressings were removed? Once the dressings are applied, all central lines sites will be monitored as part of the participant's routine care. Participation in the clinical trial lasts as long as the first central line dressing remains in place. Central line dressings currently and routinely remain in place for up to, but not more than seven days. After this period, there will be no need for any research-related observations. Routine care will continue and will not be affected by the research. Participants will not be asked to make any extra visits over and above those needed for routine care.
Vascular access involves central and peripheral vein accesses and arterial accesses. Central venous catheterization is widely used in clinical practice for diverse purposes, including hemodialysis for end stage renal failure, invasive hemodynamic monitoring, radiological studies, infusion of drugs that cannot be administered via peripheral vessels, administration of parenteral nutrition, vascular access in patients whose peripheral veins are difficult to be catheterized and for miscellaneous purposes that require access to large caliber vessels. Arterial cannulation is used for invasive arterial pressure monitoring and to ensure access for diagnostic and therapeutic interventions. In the United States and United Kingdom, guidelines have recommended the use of ultrasound guidance to reduce complications and improve success in central venous catheterization.
This first-in-human pilot study seeks to evaluate the feasibility and safety of using a percutaneous ultrasound device with needle guide for vascular access. Eligible participants will undergo the procedure of transcatheter arterial chemoembolization for primary or metastatic liver cancer, as part of participants' clinical care. The percutaneous ultrasound device with needle guide will be deployed in eligible participants at the beginning of the procedure for guiding a needle inside the femoral artery. Once the needle is inside the artery, then a guide wire is advanced inside the needle and vascular access is successfully obtained. The study will identify whether this ultrasound-based device with needle guide is helpful for guiding a needle inside the femoral artery.
