Summary
The Ash Split Cath provides durable vascular access for end-stage renal disease (ESRD) patients, showing favorable function and duration compared to AV grafts.
Area of Science:
- Nephrology
- Vascular Surgery
- Medical Devices
Background:
- End-stage renal disease (ESRD) necessitates reliable vascular access for hemodialysis.
- Traditional options like arteriovenous (AV) grafts have limitations in function and longevity.
- The Ash Split Cath offers a potential alternative for primary or bridge access.
Purpose of the Study:
- To evaluate the duration of use and functional outcomes of the Ash Split Cath.
- To compare the performance of the Split Cath with existing vascular access methods.
Main Methods:
- Prospective observational study involving 164 ESRD patients.
- Ultrasound-guided transcutaneous placement of the Split Cath in the internal jugular (IJ) vein.
- Kaplan-Meier analysis for functional duration assessment.
Main Results:
- 82% of catheters remained functional at 12 months, with a median half-life of 26 months.
- Catheter failure occurred in 36 patients, primarily due to infection (53%) or mechanical issues.
- Comparable blood flow rates were observed between Split Cath and traditional access methods.
Conclusions:
- The Ash Split Cath demonstrates favorable function, safety, and duration for ESRD patients.
- It presents a viable alternative to AV grafts for hemodialysis vascular access.

01:16Design of Transmission Shafts
The design of a transmission shaft is governed by two primary specifications: the power it transmits and its rotational speed. These parameters guide the selection of the shaft's material and cross-sectional dimensions, ensuring that the material's maximum shearing stress remains within the elastic limit while transmitting the desired power at the given speed. The system's power is intrinsically linked to the applied torque. The torque applied to the shaft can be calculated by reconfiguring the...
01:27Energy Line and Hydraulic Gradient Line
Based on Bernoulli's equation, the energy line (EL) and hydraulic grade line (HGL) provide graphical representations of energy distribution in a fluid flow system. For steady, incompressible, inviscid flows, Bernoulli's equation is expressed as:
01:23Abrasion Resistance of Concrete
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

01:26General External Flow Characteristics
The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...
01:24Single Pipe Systems
In pipe flow analysis, problems are typically categorized into three types — Type I, Type II, and Type III — based on the known parameters and the desired outcome. Each type of problem addresses specific engineering requirements using fluid properties, pipe characteristics, and operational conditions.
In a Type I problem, fluid properties (density and viscosity), pipe characteristics (including diameter, length, and surface roughness), and the flow rate or average velocity are known. The...

01:22Toughness and Hardness of Aggregate
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in the...
