1. Suturing lab

2. 
Suture may define as
Any strand of material used to ligate
blood vessels or to approximate
tissue

3. 
1. Absorbable: Suture that is completely
broken down
by the body (dissolving suture)
2. Non-absorbable: Suture is not broken
down (permanent suture)

The simple interrupted suture is the gold
standard and the most commonly employed
suture.
same depth on each side of the incision or
wound, otherwise the edges will overlap.
 Sutures are usually placed approximately 5
to 7 mm apart and 1 to 2 mm fromthe skin
edge,

12. 
Vertical mattress sutures may be used
when eversion of the skin edges is
desired and cannot be accomplished
with simple sutures alone.
Vertical mattress sutures tend to leave
the most obvious and unsightly cross-
hatching if not removed early

14. 
Horizontal mattress sutures also
provide approximation of the skin
edges with eversion.
They are particularly
advantageous in thick glabrous
skin (feet and hand).

16. 
known as running simple sutures
can be placed rapidly but depend
on the wound edges being more-
or-less approximated beforehand.
 A continuous suture is not nearly
as precise as interrupted sutures

Over Suture

18. 
Skin staples are particularly useful as a
time saver for long incisions or to
position a skin closure or flap
temporarily before suturing.
Staples must be removed early to
prevent skin marks and are ideal for the
hair-bearing scalp

20. 
Skin tapes can effectively approximate
the wound edges, although buried
sutures are often required in addition
to skin tape to approximate deeper
layers.
Skin tapes can also be used after skin
sutures are removed to provide added
strength to the closure
Skin Tapes

22. 
Skin adhesives have been developed,
and may have a role in wound closure,
especially in areas where there is no
tension on the closure, or where
strength of closure has been provided
by a layer of buried dermal sutures.
Adhesives, by themselves, however, do
not evert the wound edges.
