What thread is used in surgery?

Sutures used in surgical procedures are typically made from a variety of synthetic or natural materials such as:

1. Synthetic Materials:

a. Nylon (Polyamide): Known for its strength, flexibility, and resistance to infection. Commonly used in general surgeries and skin closure.

b. Polypropylene: A non-absorbable suture that is strong, inert, and less likely to cause tissue reactions than other materials. Often used in surgeries where permanent or long-term wound support is required.

c. Polyester: Another non-absorbable, high-tensile strength suture. It's resistant to enzymatic degradation, making it suitable for prolonged wound closure.

2. Natural Materials:

a. Silk: A natural suture derived from the filaments produced by silkworms. Although strong, silk sutures are not commonly used in surgeries today due to their higher potential for causing tissue reactions and attracting bacteria.

b. Cotton: Not used as often as other materials due to its tendency to absorb fluids and provide less consistent strength.

3. Absorbable Materials:

a. Polydioxanone (PDS): A synthetic material that is gradually absorbed by the body over time. It's commonly used in surgeries where minimal scarring and wound strength is desired.

b. Poliglecaprone 25 (Monocryl): Similar to PDS, Monocryl is an absorbable synthetic material that is used for various surgical procedures.

c. Polyglycolic Acid (PGA): An absorbable synthetic suture that is typically used in soft tissue repair and gastrointestinal surgeries.

The choice of suture depends on several factors such as the location of the surgery, the nature of the tissue being repaired, and the desired rate of absorption or wound healing.
