What is a sterile gauze?
type of thin fabric with a very open weave
Purpose of a sterile gauze
- Use to protect open wounds
- Absorb bodily fluids
- For cleaning other instruments used during the procedure
It is designed to introduce a drug into the body
syringe
What are the parts of the syringe?
Plunger, Barrel, Hub
Part of the syringe that is used to fill or empty the barrel with fluid
Plunger
Part of the syringe that contains fluid
Barrel
The Hub, which is part of the syringe, is designed for?
lock the needle in place while using the syringe
another term for percutaneous needle
Percutaneous entry needle
Parts of the percutaneous needle
Cannula, Hub, Baseplate
Part of the percutaneous needle that is a long hollow tube through which CM, blood, guidewire or other materials will pass
Cannula
The hub that is part of the needle is for what?
permits attachment of a syringe/other equipment to the needle
What is the baseplate for in the percutaneous needle?
facilitates the puncture by allowing the angiographer to grasp the needle more securely
This is the measure of the size of the needle
Gauge
What is the rule for the gauge sizes?
The higher the gauge, the smaller the inner diameter of the needle lumen
What is the smallest gauge size?
14
What is the safest gauge size for the IV insertion
18
It is the measure from the tip of the cannula to the point where the cannula meets the hub
Length
What are the common length of arterial needles?
2 1/8 inches and 3 1/4 inches
What is the thickness?
Refers to the walls of the cannula
What are the classifications of needles?
thin walled and regular walled needle
It is solid, has cutting edge and inserted into the cannula of the needle
Stylet
It is made of solid metal and prevents backflow of blood through the needle
Obturator
This is small and extremely sharp bladed instrument
Scalpel
What si the purpose of the scalpel
Used to cut tissue with less trauma than any other instrument
What is the function of an adapter
connect one accessory equipment to the other
What materials can the adapter be made of?
plastic/metal
What are the classifications of adapters?
Male & female
What is the function of a stopcock?
Controls the flow of fluid from one area to the other
Classifications of stopcocks
male & female
2 types of stopcocks
2-way and 3-way
Difference between a 2-way & 3-way stopcock
2-way - allows the flow of fluid to and from two items
3-way - allows the flow of fluid to and from three items
These are a series of stopcock attached to one another
Manifolds
What are the purposes of waste management lines & bags?
- Facilitates the safe collection of fluid waste
- Also allows the administration of saline and contrast solutions
- Minimizes contact with infectious blood and bodily fluids
- Leak-resistant dual check valves make disposal clean and easy
These are patented designs with built up
lip and recessed bottom
Sterile basins
Purpose of the sterile basins
hold guidewire in place and allow easy removal
What is the primary purpose of draping the surgical patient?
Isolate the surgical site from the other areas of the patient’s body and nonsterile areas of the O.R. table in order to contribute to reducing
the risk of surgical site infection (SSI)
What is heparin?
It is a drug that works as an anticoagulant
It is often used as a flush, which is a small amount of fluid run through an IV port or locks to dissolve any blood clots the patient might
have formed that could block the IV fluid from entering the vein
Heparin
This provides a place to safely park needles prior to terminal disposal
Sharps container
This closed bowl minimizes staff and patient exposure to blood-borne pathogens
Contaminated waste container
What kind of contrast media is used in interventional radiography?
Non-ionic Low Osmolality Contrast Media
What are the advantages of contrast-saver sets?
- Minimizes contrast waste
- Maximizes potential savings
This facilitates the introduction of the catheter over the guidewire by dilating the path of the catheter
Vessel dilators
What kind of measurement is used for vessel dilators?
French sizes
what is the usual length of vessel dilators
5 inches to 6 inches
This comes with the dilator and it is left in
place when the dilator is removed.
Introducer sheath
This protects the vessel wall at the puncture site during catheter manipulation.
Introducer sheath
What are the different emergency products used during an interventional procedure?
- Antihypertensive Drugs
- Inotropics
- Antihistamine
What are the 2 kinds of hypertensive drugs included in the emergency products
alpha blockers & beta blockers
what is the inotropic included in the emergency products?
digitalis
What are the things needed for the preparation of the entry site?
razors
lidocaine
sterile gloves
antiseptic soap solution
sterile bins
drapes & towels
This C-arm orientation has the least exposure to the operator
Vertical PA
What does the 30 degrees c-arm tilt do?
Increase exposure to face & neck by factor of 4
What does the horizontal c-arm orientation do?
increased exposure at x-ray tube end
Which c-arm orientation should be avoided because there is an increased exposure to the head & neck
vertical AP
