Principle of suture
history
The oldest known suture of the world was
found on a
mummy’s abdomen.
 It was applied about 1100 BC.
 Egypt :
Plant fibers,
Hair,
Tendons and
Wool threads
 Silver wire for wound clamping
AULUS CORNELIUS CELSUS ( 25 BC to 50
CE)
 He was the first to produce detailed
description of
ligatures used for hemostasis.
 He knew both Continuous and simple
sutures.
Rhazes of Arabia was credited in 900 A.D.
with first
employing “KITGUT” to suture abdominal
wounds.

 ADEQUATE STRENGTH : (TENSILE STRENGTH)
 LOW TISSUE IRRITATION AND REACTION :
 LOW CAPILLARITY : wicking phenomena
 Good handling and knotting properties
 Sterilization without deterioration.
Resorbable
Surgical gut (Natural)

Polyglycolic acid Homopolymer of glycolide
PRINCIPLES OF SUTURING
 The needle should be grasped at approx. one third
the
distance from the eye and two thirds from the point.
 The needle should enter the tissues perpendicular to
the
tissue surface.
 The needle should be passed through the tissues
along its
curve.
 The suture should be passed at an equal depth and
distance
from the incision on both sides.
 The needle always passes from the thinner tissue to
the
thicker tissue.
 The needle always passes from the deeper to the
The sutures should be tied only to approximate the
tissues , not
to blanch.
 The knot should never lie on the incison line.
 Sutures should be placed at a greater depth than
the distance
from the incision , so as to evert the wound
margins.
 Sutures on the skin are usually removed in 5 days
and
intraoral sutures in 7 days. If there is a tension /
stress
while suturing ; the suture may be kept for 10 days.
