Brief Suture History

• 3000 BCE - Linen strips and animal sinew (tendon) were used to close wounds with needles made of bone

• 600 BCE - Cotton, leather, horsehair, and bark fiber from trees was used to close wounds

Brief Suture History

• Lister (late 1800s) was the first to use a bacteriocide (carbolic acid) on suture

• Suture manufacture and sterilization started in the early 20th Century

• First synthetic absorbable suture was produced in the 1960s

Specifications for Suture Material

• Must be sterile and sterile technique must be used when handling

• Uniform tensile strength• Uniform size• Appropriate diameter for tissue type• Provide knot security• Cause minimal foreign body tissue reaction

Suture Selection

• Characteristics of the suture material

• Age• Weight• Allergy status• General tissue condition

• Surgical site disease• Comorbid condition(s)• Surgeon preference• Suture availability• Cost• Mentor influence

Ideal Suture Characteristics

• Pliable• Easy to tie secure knots• Tensile strength (will not fray or break)• Glide through tissue effortlessly• Inert• Nonallergenic• Inexpensive

Tensile Strength

Tensile strength of absorbable and non-absorbable sutures is critical both during and after surgical procedures. Breaking strength and elongation can be measured using either a "straight pull" test or a "knot pull" test.

Anatomy of a Needle

– Eye– Point– Body– Shape– Chord Length

Needle Points

– Taper – most internal tissues

– Cutting – Skin and other tough tissues

– Reverse Cutting – Tendon sheath, bone, cornea, other tough tissues

– Blunt – Liver and other friable tissues

Commonly Used Needle Codes (Ethicon)

• CP• CT• CTX• CV• FS• FSL• FSLX• KS

• MO• SH• TF• OS• UR• PS• RB• S

Suture Handling

Needle holder is clamped onto the

needle approximately 1/3 the distance from the swage to the point

Suture Handling

Suture is removed from the package placing

tension on the swage

Suture Handling

Tie Terms

• Free-tie – Place a suture (no needle) into the surgeons

hands• Stick-tie

– Suture on a needle (use a needle holder)• Tie on a pass

– Place the suture (no needle) on an instrument (tonsil/right angle)

• Ligate– To tie
