The document discusses sutures and suturing materials. It defines sutures as stitches used to approximate wound edges to help healing. Suture materials are synthetic fibers that hold wounds closed until natural scar formation. The goals of suturing are wound edge apposition, tension, hemostasis, and infection prevention to produce a good scar. Suture characteristics include physical structure as monofilament or multifilament, tensile strength, absorbability, and biological behavior depending on material. Commonly used suture materials discussed are polypropylene, silk, and vicryl.

3. DEFINITION
 what is suture?
• Suture is a stich or series of stiches made to
secure apposition of the edges of a surgical or
traumatic wound.
 What is suture material?
• Suture material is an artificial fibers used to
keep wound together until they hold themselves
by natural which is
synthesized & oven into a stronger scar.

4. GOALS OF
SUTURING
 Wound edge apposition.
 Provide adequate tension.
 Maintain hemostasis.
 Aid in wound healing.
 Avoid wound infection.
 Produce aesthetically pleasing scar by
approximating skin edges.

5. SUTURE
CHARACTERISTICS

6. PHYSICAL
STRUCTURE
MONOFILAMENT-
 This suture material is smooth &
tends to slide through tissues
easily.
 Difficult to knot.
 Can be damaged by gripping it with
needle holder or forceps.That can
lead to fracture of the suture materials.

7. PHYSICAL
STRUCTURE
MULTIFILAMENTS
 Easy to knot.
 Have a greater surface area
than monofilaments.
 Have a capillary actions where bacteria
may lodge & be responsible for
persistent infections.
 This material can be coated with silicone
in order to make it smooth.

10. TENSILE
STRENGTH
•It can be expressed as the force required to
break it when pulling the two ends apart.It
depends upon –
 Constituent of suture materials.
 Thickness of suture materials.
 How it is handled in the tissues.

11. ABSORBABILITY
• Suture materials may be absorbable or
non-absorbable.This property must be taken
into consideration when choosing suture
materials for specific wound closures. Oral
mucosa & Deep sturcture need to be
absorbable suture materials but vascular
anastomoses need non-absorbable suture
materials.
 Biological Behaviour:
• It depends upon the constituent of raw
materials.

12. BIOLOGICAL
BEHAVIOUR • It depends upon the constituent of raw
materials.

13. ARMAMENTARIUM
OF SUTURING
 Needle holder
 A suture needle
 Suture material

14. HOW TO HOLD
• The needle holder is held with
thumb & ring finger through the
rings & with the index finger
along the length of needle
holder to provide stability &
control.
