What is PDS in suture?

Polydioxanone (PDS II) is a synthetic, absorbable, monofilament suture made from a polymer of paradioxanone (Figure 2). It has greater initial tensile strength than polyglycolic acid and polyglactin 910 but has the poorest knot security of all the synthetic absorbable sutures.

When do you use PDS suture?

PDS II (polydioxanone) Suture is indicated for soft tissue approximation and ligation, including use for ophthalmic procedures and in pediatric cardiovascular tissue where growth is anticipated. The suture is not indicated for microsurgery or adult cardiovascular and neurological tissues.

What are the 4 types of sutures?

These types of sutures can all be used generally for soft tissue repair, including for both cardiovascular and neurological procedures.

  • Nylon. A natural monofilament suture.
  • Polypropylene (Prolene). A synthetic monofilament suture.
  • Silk. A braided natural suture.
  • Polyester (Ethibond). A braided synthetic suture.

Is PDS suture natural or synthetic?

3.1. 5 Polydioxanone (PDS II, PDS Plus Antibacterial) Polydioxanone is a synthetic, absorbable, monofilament suture made from polymer of paradioxanone (Fig. 2).

What is a #1 PDS suture?

PDS II Suture is a sterile synthetic absorbable monofilament suture made from the polyester (p-dioxanone.) 1. PDS II sutures are intended for use in general soft tissue approximation, including use in paediatric cardiovascular tissue, in microsurgery and in ophthalmic surgery.

What is Loop PDS?

Starting at the superior or inferior aspect of the incision, the looped PDS is passed through the vertex of the fascia (see the image below). The needle is then passed through the loop locking the stitch in order to anchor the knot or tied if it is not a looped suture.

When do PDS sutures dissolve?

In vivo experiments on rats showed a slight tissue reaction and a dissolution time of 120-180 days for Maxon and 180-240 days for PDS. With Maxon, tensile strength was measurable for 42-49 days, while the period for PDS amounted to 65-80 days.

Are 3 0 Vicryl sutures dissolvable?

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.

What color is PDS suture?


Material Polydioxanone
Colour Violet
Absorption Hydrolysis
Sizes 6-0,5-0,4-0,3-0,2-0,0,1
Tissue Reaction Grade-1, Reactivity – Slight

What are the 2 types of sutures?

There are two types of sutures, absorbable and non-absorbable. Absorbable sutures will naturally break down in the body over time while non-absorbable sutures are made of synthetic material that is removed after a certain period of time.

What are the 3 major cranial sutures?

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 chromic catgut?

Chromic catgut is a modification of plain catgut that is tanned with chromic salts to improve strength and delay dissolution. 29. Gut is absorbed by phagocytosis, and is associated with a marked tissue inflammation that can be detrimental to healing.

What is PDS material?

Polydioxanone (PDS) or poly-p-dioxanone is a slowly absorbable monofilament suture composed of the polyester, poly (p-dioxanone). This is a monofilament with greater strength than monofilament nylon and polypropylene, and with less tissue drag than the multifilament materials.

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 are blue sutures?

PROLENE Sutures (clear or pigmented) are non-absorbable, sterile surgical sutures composed of an isotactic crystalline steroisomer of polypropylene, a synthetic linear polyolefin. The suture is pigment blue to enhance visibility.

Is Maxon same as PDS?

PDS is similar to Maxon in terms of absorption and strength, but it has better handling and less memory.

How long does 4 0 Monocryl take to dissolve?

Monocryl has a low tissue reactivity, maintains high tensile strength, and has a half-life of 7 to 14 days. At 1 week, its in vivo tensile strength is at 50–60% undyed (60–70% dyed), 20–30% undyed (30–40% dyed) at two weeks, and essentially completely hydrolyzed by 91–119 days.

When do you use Prolonne vs nylon?

Nylon (eg ethilon) is a synthetic monofilament material widely used for skin suture. Polypropylene (prolene) is often preferred to nylon as it is thought to be slightly more inert. It is widely used for abdominal wall closure.

What suture is used to close the fascia?

Nonabsorbable sutures are used in fascial closure. The surgeon pulls apart the fascial layer with two clamps. A looped synthetic material known as polydioxanone (PDS) is used for suturing.

What is fascial closure?

Fascial closure is the closure of the inner layers of the abdomen after a major surgery involving an incision on the abdomen. Fascial closure prevents hernia formation. The fascial closure technique is of two types: layered closure and mass closure.

What suture is used to close skin?

Percutaneous closure — The simple interrupted suture is the most common method used to close most small, uncomplicated, traumatic skin lacerations [1,14,15]. For proper healing, the edges of the wound must be everted by each stitch.

Is PDS suture absorbable?

PDS (polydioxanone suture), a new synthetic absorbable suture, was used in 21 patients undergoing cataract surgery. It still retains 25% of its tensile strength at 42 days but absorption takes 130-180 days.

How long does it take for 3 0 Vicryl sutures to dissolve?

Coated VICRYL RAPIDE (polyglactin 910) Suture will normally start to dissolve within 7-10 days after surgery and can then be removed using sterile gauze. Because of the faster dissolution rate, the suture remains do not need to be removed later after healing.

Which is a non-absorbable suture?

Nonabsorbable synthetic sutures include the following: Nylon (Ethilon/Monosof [monofilament] and Nurolon/Surgilon [braided]) Polyester fiber (Mersilene/Surgidac [uncoated] and Ethibond/Ti-cron [coated]) Polybutester (Novafil)

What are Vicryl sutures used for?

Vicryl sutures were used to suture small and large intestine, peritoneum, fascia, muscle, subcutaneous tissue, and skin and were used in thoracotomy closure.

What type of suture is absorbable?

Types of Absorbable sutures include : Polyglycolic Acid sutures, Polyglactin 910 , Catgut, Poliglecaprone 25 and Polydioxanone sutures.

Are 6 0 nylon sutures dissolvable?

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. … LINEX – MONOFILAMENT NYLON SUTURE.

What is a polyester suture?

Polyester suture is a braided and coated suture (silicone) and is a non-absorbable suture composed of Polyethylene terephthalate fiber. Polyester sutures have excellent tensile strength, soft and pliable with excellent braiding and are an excellent choice for cardiovascular and ophthalmic surgery.
