Suture materials: non-absorbable

Contributor(s): Tad Coles, Otto Lanz, David Neck

Introduction

Definition of suture

  • Material used to ligate vessels or approximate tissues.

Historical perspective

  • Celsus - first recorded use of vessel ligation for hemostasis.
  • Galen (200 AD) - used silk suture material.
  • Physick (1800's) - produced absorbable sutures from the skin of goats.
  • Lister (1869) - introduction of suture sterilization and treatment of catgut with chromic acid.
  • 1940's - appearance of synthetic sutures.

Characteristics of ideal suture material:

  • Maintains adequate tensile strength until wound healing well established.
  • Bioinert (minimally reactive, non toxic, non allergenic, non carcinogenic).
  • Sterilized without alteration in physical properties.
  • Preferably monofilament (non capillary).
  • Economical.

 Suture classification

Absorbable vs non absorbable

Absorbable

  • Undergoes degradation and rapid loss of tensile strength within 60 days.
  • Degradation occurs either through phagocytosis by macrophages brought in during wound healing or by enzyme hydrolysis.

Non-absorbable

  • Retains tensile strength > 60 days.
  • Remains in tissues until removed, although may fragment.  Absorption and loss of tensile strength are different properties. Absorbable sutures may remain in the tissues for > 60 days but retain none of their original tensile strength.

Natural vs synthetic

Monofilament vs multifilament

Monofilament

  • Single strand of material.

Multifilament

  • Consists of multiple strands of material "braided" or twisted to produce a single strand.
  • May serve as a nidus for infection by harboring bacteria in the interstices between strands.
  • "Coating" with various materials may improve their handling characteristics.

Capillary vs. noncapillary

Capillary

  • Sutures absorb fluids and "wick" them along the suture, potentially transporting bacteria into the wound site.
  • Not recommended for use in skin or for penetration of the lumen of a hollow viscus.
