Silk Suture

The silk suture is a non-absorbable/braided material. The suture material composed of an organic protein called fibroin. Fibroin a specialized protein derived from the species of family Bombycidae. The cocoon of silkworm larvae

The suture coated with the wax which helps in lubrication and avoids erosion of tissue.


Natural material and used almost in all the department of surgical departments and in anesthesia.

In anesthesia, this suture is used in fixation of the central venous catheter (CVP), Femoral catheter, dialysis catheter etc.

Used in the closure of skin and subcutaneous tissue most of the surgery. In some case, the suture is replaced by the

Surgical skin stapler, 2 octyl cyanoacrylate solution etc.

Types of silk sutures

Silk available in dyed and undyed silk suture.

Plain silk suture non-absorbable suture and braided suture. Biological/natural suture derived from the cocoon of the silkworm larva.

Coated with wax to reduce capillary action of the  braided suture

Knot security is good and low cost

Tissue reaction not good compared to other suture-like monocryl or Nylon suture

Silk Suture

Suture with dyed (blue in color) – Methylene blue

Silk suture without dyed (black)- Hematein HCK

The suture is available in different types like in gauges, sizes and in lengths etc.

The suture has impinged into the stainless steel needle.

Mersilk same like other silk used in ligating the bleeder and for anastomosis

Mersilk a non-absorbable suture and braided

The needles are coming in different types

  1. Cutting type needle
  2. Taper cut needle
  3. Round body needle
  4. Reverse cutting etc.


Used for the approximation of soft tissue and in ligation of tissue in the abdominal surgery, cardiovascular surgery, ophthalmology surgery and in neurosurgery.

The suture selected for particular patients, tissue conditions, surgical techniques, and wound sizes etc.

Silk suture elicits an initial inflammatory reaction in tissue and fibrous connective tissue enhance the encapsulation of suture.


Allergy to the skin

Sensitivity to the silk suture

Recommended to permanent retention of tensile strength

Sterilization of the suture before packing must be done with the either by Ethylene oxide sterilization or Irradiation methods

Once it opened, don’t desterilize the suture and store in 25-degree centigrade

Keep away from the moisture, fluid and overheat.

The main drawback of the suture includes

Coating reduced knot security

Incites tissue reaction



Complication such as infection and sinus formation
