What is the most common suture size?

Most commonly, you will use a suture somewhere between 3-0 and 6-0. Small sutures, such as 5-0 and 6-0 are used on the face. Larger sutures, 3-0 and 4-0, are best for areas where appearance is not of great concern such as the extremities.

What is the smallest size suture?

Sutures are available from a size 10-0 (smallest size) to a 5 (largest size). When discussing/verbalizing suture sizes, they are referred to as number 1, 2, 3, 4 or 5 and 0 (zero or “oh”), 2-(“oh”) and so on. Note: One will not hear anyone ask for a 1-0 (“oh”) suture.

What are blue sutures?

Polypropylene sutures are blue colored for easy identification during surgery. Polypropylene sutures have excellent tensile strength and are used for orthopaedic, plastic and micro surgeries, general closure and cardiovascular surgeries. Polypropylene sutures are popularly known as Prolene sutures.

What are the different types of sutures?

There are two varieties of sutures: absorbable and non-absorbable.

Sutures are numbered by their size relative to their diameter. Thick suture numbering is from 0-10, with #10 being the largest diameter.

What are Vicryl sutures?

Vicryl (polyglactin 910) is an absorbable, synthetic, usually braided suture, manufactured by Ethicon Inc., a subsidiary of Johnson and Johnson. A monofilament version is also made for use in ophthalmic practice. It is indicated for soft tissue approximation and ligation.

Which suture is thinnest?

Sizes. Suture sizes are defined by the United States Pharmacopeia (U.S.P.). Sutures were originally manufactured ranging in size from #1 to #6, with #1 being the smallest. A #4 suture would be roughly the diameter of a tennis racquet string.

How do I choose sutures?

Bottom Line

  1. The best suture for a given laceration is the smallest diameter suture, which will adequately counteract static and dynamic tension forces on the skin.
  2. The stronger an absorbable suture is, the greater its absorption time, and the greater its risk of causing a foreign body reaction within a wound.

How do you read suture sizes?

The size (4-0, 3-0 etc) describes the diameter of the suture strand. It is important to note that the larger the number prefix, the smaller the diameter of the thread. For example, 7-0 commonly used for facial lacerations in plastic surgery is much finer than 1-0 or 0, commonly used to close a midline laparotomy.

What are 2-0 sutures used for?

2 and above &gt,0.5 Large tendon repairs, thick fascial closures, drain sutures (usually orthopaedic surgery)

What size suture is used to close skin?

Optimal cosmetic results can be achieved by using the finest suture possible, depending on skin thickness and wound tension. In general, a 3–0 or 4–0 suture is appropriate on the trunk, 4–0 or 5–0 on the extremities and scalp, and 5–0 or 6–0 on the face.

What is a 2-0 suture?

Size refers to diameter of the suture strand. the larger the suture diameter, the relatively stronger it is. measured in metric units (tenths of a millimeter) or by a numeric scale standardized by USP regulations. USP scale runs from 11-0 (smallest) to #7 (largest) zeros are written as 2-0 for 00 and 3-0 for 000, etc.

What is a nylon suture?

Nylon sutures are also known as polyamide sutures. Nylon sutures are monofilament sutures and are remarkably smooth, soft and gives excellent knot security. Nylon sutures are non-absorbable sutures and possess excellent tensile strength.

What is chromic suture used for?

Chromic Gut sutures are used most for Ophthalmic, Obstetrics/Gynaecology, Orthopaedics, Gastro-intestinal Tract Surgery and general closure. These sutures are also great for minimal acute inflammatory reaction in tissue.

What color is nylon suture?

Indications: Nylon suture is indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, neurological, and ophthalmic procedures. Colors: Black (colorant: logwood extract)

Is Chromic Gut monofilament or multifilament?

Commonly Used Suture Types in ED

Brand Name
Absorbable Monofilament Chromic Gut
Non-absorbable Multifilament Ethibond

What suture is not recommended for skin closure?

Silk is a non-absorbable braided suture material that can acuse tissue reactions and may wick microorganisms into the wound. It is not recommended for skin closure.

Which suture absorbs the fastest?

Absorbable Sutures

Effective Wound Support Best Use
Fast Absorbing Gut 5-7 days Face

What are the 4 main sutures of skull?

The major sutures of the skull include the following:

  • Metopic suture. This extends from the top of the head down the middle of the forehead, toward the nose. …
  • Coronal suture. This extends from ear to ear. …
  • Sagittal suture. …
  • Lambdoid suture.

What is the difference between Vicryl and Vicryl Rapide?

The main difference between the two sutures is the rate of absorption: Vicryl Rapide® is irradiated and hence is absorbed much more quickly than Vicryl®. Vicryl® has 75% of its original breaking strength at 14 days and 50% at 21 days. In contrast, Vicryl Rapide® has 50% at 5 days and almost none at 14 days.

How are sutures classified?

Broadly, sutures can be classified into absorbable or non-absorbable materials. They can be further sub-classified into synthetic or natural sutures, and monofilament or multifilament sutures.

What is polyamide suture?

Polyamide suture is a monofilament non-absorbable, sterile surgical suture composed is a macromolecule with repeating units linked by amide bonds. Polyamide is synthesized by ring opening polymerization of caprolactam. Caprolactam has 6 carbons, hence the name ‘Nylon 6’.

What is Polyglactin 910 suture?

Polyglactin 910 (Vicryl: Ethicon Inc, Somerville, NJ)

It is a coated, braided, multifilament suture like polyglycolic acid. Polyglactin 910 consists of a copolymer made from 90% glycolide and 10% l-lactide. This suture has similar handling properties to polyglycolic acid but has more tensile strength.

What is silk suture?

Silk is a natural non-absorbable suture material that has been widely used for wound ligation, it was the most common natural suture, surpassing collagen, used in the biomedical industry during the past 100 years. During the past 25 years, a range of degradable synthetic sutures has dominated the suture market.

What is Vicryl used for?

VICRYL Suture is a synthetic absorbable suture coated with a lactide and glycolide copolymer plus calcium stearate. It is indicated for use in general soft tissue approximation and/or ligation, including ophthalmic procedures, but not cardiovascular or neurological tissues.

Which type of suture is the most widely used?

Simple interrupted suture: It is the most common and simple form of suturing technique. The suture is placed by inserting the needle perpendicular to the epidermis. Inserting it perpendicularly helps in a wider bite of deeper tissue to be included in the suture than at the surface leading to rapid wound healing.

When do you use Vicryl sutures?

Coated Vicryl is indicated for use in ligation or general soft tissue approximation. Vicryl Rapide is indicated only when short-term wound care is needed and for use in superficial soft tissue suturing.

What sutures to use on forehead?

Suture Material Choice

For mild to moderate tension closures on the forehead, 5-0 absorbable suture is generally sufficient. Using a small needle, such as the P-3 reverse cutting needle, is often adequate.

Can you stitch a cut after 12 hours?

Your risk of infection increases the longer the wound remains open. Most wounds that require closure should be stitched, stapled, or closed with skin adhesives (also called liquid stitches) within 6 to 8 hours after the injury. Some wounds that require treatment can be closed as long as 24 hours after the injury.

Can you use Vicryl on the face?

It is well-known that absorbable sutures (like Vicryl) can be used on the face and reinforced with tissue adhesives and have similar healing rates as non-absorbable threads. We highly recommend using Vicryl for facial wounds.
