55 Questions
What is the main difference between absorption through phagocytosis and hydrolysis?
Phagocytosis is a more aggressive form of absorption than hydrolysis
What is the advantage of using monofilament over multifilament when there is an infection in the wound?
Monofilament has a smaller surface area, reducing the risk of further bacterial colonization
What is the difference between the sizing of suture materials in the EU and the US?
EU uses the metric system based on the size diameter of suture material, while the US uses tensile strength
What is the advantage of using swaged needles over eyed needles?
Swaged needles cause minimal tissue trauma and are single-use
What is the property of needles that allows them to bend rather than break?
Ductility
What is the advantage of natural suture materials over synthetic ones?
Easy to knot
What is the difference between absorbable and non-absorbable suture materials?
Absorbable sutures disappear while non-absorbable sutures stay in place indefinitely
What is the advantage of multifilament suture materials over monofilament ones?
Excellent knotting
What is tissue drag or chatter?
How easy the suture material passes through the tissues we are suturing
What is the difference between natural and synthetic suture materials in terms of histocompatibility?
Natural suture materials have high histocompatibility while synthetic ones have low histocompatibility
What are the ideal characteristics of an ideal suture material?
High tensile strength, easy-to-use for surgeons, easy to tie knot, highly uniform tensile strength, non-toxic, non-carcinogenic and non-allergenic, easily sterilised, minimise bacterial adhesion, standardisable characteristics, maintain its properties for sufficient time, inexpensive
What is the process of applying a suture called?
Suturing

What is the process of bringing tissues together and keeping them together while healing occurs called?
Suturing
What is the ideal characteristic of suture material that inhibits tissue reactions and wicking?
Non-toxic and non-carcinogenic
What is the material used to close blood vessels and stop haemorrhages known as?
Ligament
Why is there no ideal suture material that is useful for all surgical procedures?

What is an example of a natural suture material?
Catgut
What is the advantage of using natural suture materials over synthetic ones in terms of knotting?
Natural materials have better knotting than synthetic ones
What is the definition of an absorbable suture material?
A material that is fully degraded and absorbed by the body once it's been placed
What is the advantage of using non-absorbable suture materials?
They provide indefinite support
What is the difference between monofilament and multifilament suture materials in terms of tissue trauma?
Monofilament causes greater tissue trauma than multifilament
What is the property of monofilament suture materials that makes them potentially more difficult to tie knots with safely?
Greater memory
What is the process by which suture material is absorbed through phagocytosis or hydrolysis called?
Suture material absorption
What is the difference between the sizing of suture materials in the EU and the US?
EU sizes based on diameter, US sizes based on tensile strength
What is the advantage of using catgut as a suture material?
It is absorbed through phagocytosis, which is less aggressive than hydrolysis
What is the difference between swaged needles and eyed needles?
Swaged needles are less traumatic to tissues than eyed needles
What is the most important part of a needle?
The point

What is the advantage of using natural suture materials over synthetic ones?
better biocompatibility
What is tissue drag or chatter?
the resistance encountered when the needle and suture material pass through the tissue
What is the process of absorbing suture material called?
hydrolysis
______ is a natural product and is absorbed through phagocytosis, whereas a lot of synthetic suture materials are absorbed through hydrolysis so less aggressive
