What is cannulation technique?

What is cannulation technique?

The four cannulation techniques, rope ladder (RL), area puncture (AP), buttonhole with blunt needles (BHb), and buttonhole with sharp needles (BHs), affects the arteriovenous fistula (AVF) in different ways.

What is buttonhole technique?

The buttonhole technique is a way to “cannulate,” which means “to insert dialysis needles.” Instead of sharp, pointed needles, dull needles are placed into the exact same holes on your fistula every time you have dialysis. Inserting the needles in the same holes creates a “tunneled track” for the needle.

Why do we rotate needle sites on a fistula?

6 The needle bevel is rotated to help prevent a “back wall” or posterior wall infiltration, which can occur if the needle’s bevel tip accidentally punctures the bottom of the graft or fistula (see the discussion under “Cannulation Problem Solving”).

How do you Innulate a new fistula?

1. Apply a tourniquet to the access arm.
2. After disinfecting the access site per unit protocol, carefully cannulate the fistula, using a 25° insertion angle.
3. When blood flash is observed, flatten the angle of the needle, parallel to the skin, and advance slowly.

What is the patient cannulation technique?

The best type of cannulation technique, rotating site versus constant site (or buttonhole), is currently debated, but the increase in infectious complications observed with the buttonhole technique suggests a prudent use of this technique, restricting it to specific patients.

What is the type of cannula?

There are two main types of cannula: IV cannulas: IV cannulas consist of short, flexible tubing doctors place into a vein. Nasal cannulas: Nasal cannulas consist of flexible tubing that sits inside the nostrils and delivers oxygen.

What is vascular access for hemodialysis?

A hemodialysis access, or vascular access, is a way to reach the blood for hemodialysis. The access allows blood to travel through soft tubes to the dialysis machine where it is cleaned as it passes through a special filter, called a dialyzer. An access is placed by a minor surgery.

What is dialysis used to treat?

Dialysis is a treatment for people whose kidneys are failing. When you have kidney failure, your kidneys don’t filter blood the way they should. As a result, wastes and toxins build up in your bloodstream. Dialysis does the work of your kidneys, removing waste products and excess fluid from the blood.

What is fistula cannulation?

The other needle option is known as a “fistula cannula,” “fistula catheter,” or “plastic” needle that is designed specifically for hemodialysis cannulation. The basic design is a sharp metal needle housed within a flexible plastic sheath.

What is dialysis cannulation?

Cannulation (needling, sticking) is the act of establishing a “canal” between an arterialized vein (the fistula or graft) and the system of blood lines that allow blood to be circulated between the patient and the dialysis machine.

What taping technique should be used for fistula needles?

For taping the needles, the “Butterfly” or “Chevron” technique is widely recommended by expert nurses; there should always be a Chevron of tape to anchor the needle against any tugging on the tubing,15 however as noted by Lee,5 other taping techniques are commonly seen in practice.

What are the types of IV cannula?

There are 3 main types of IV cannulas, namely: peripheral IV Cannula, central line IV cannula and mid-line IV cannula. The central line intravenous cannulas are used for long term treatments, followed by midline cannulas used in less invasive scenarios.
