Wound Closure Flashcards
what is a wound?
an injury in which there is a forcible break in the continuity of the soft tissue
Methods of wound closure
sutures
staples
tissue glue
skin adhesive
adhesive tape
Suture
Hold the wound edges in opposition until the wound can regain normal tensile strength without the support of the sutures
sututres
Non - absorbable
Absorbable
natural or synthetic
Monofilament or multifilament
coated or uncoated
antibacterial
pros of suture material
suitable for any situation
long shelf life
readily sterilised by steam
good knot security
tie easily with no tendency to slip or loosen.
what if suture is too tight
tear through skin swells
causes itchiness resulting in patient interference
constrict vessels at wound edge > delayed healing
Ligatures
ligation - the use of suture material and surgical knots to occlude blood vessels
disadvantage - foreign body left in wound
Staples
usually packed in a gun type applicator
traumatic but are quick, cheap and don’t always require sedation
skin staples are the most commonly used but there are specialised staples for intestinal anastomosesm and vessel ligation
Tissue glue
used for skin closure, it is designed for rapid healing and is most commonly used on superficial wounds
mildly irritating, can promote interference
other adhesives
skin adhesive - a flexible secure skin closure which can add strength and can inhibit bacteria
adhesive tape - mainly used in human skin cosure often used in large animal abdominal closure
