Suture material

Degraded within the tissues and lose tensile strength by 60 days....

• Absorbable suture material

• Non-absorbable suture material

Which material is most likely to produce a tissue reaction?

• Catgut

• Polydioxanone

• Polyglactin 910

• Polypropylene

Answer explanation

Catgut is removed by Phagocytosis which can cause a tissue reaction.

Which is multifilament?

• Poliglecaprone (Monocryl)

• Polyamide (Ethilon)

• Polyglactin 910 (Vicryl)

• Polyethylene (Dermalene)

How are synthetic suture materials absorbed?

• Phagocytosis

• Hydrolysis

Suture selection - Skin

• Polyglactin 910 (Vicryl)

• Polypropylene (Prolene)

• Chromic Catgut

• Polyglycolic acid (Dexon)

Suture selection - blood vessels

• Polypropylene (Prolene)

• Polyglactin 910 (Vicryl)

• Polydioxanone (PDS)

• Linen (Supramid)

The tendency of the material to return to it’s original shape....

• Knot security

• Memory

• Chatter

• Capillarity

The lack of smoothness as a throw of a knot is tightened down

• Knot security

• Memory

• Chatter

• Capillarity

The extent to which tissue fluid is attracted along the suture material

• Knot security

• Memory

• Chatter

• Capillarity

How long does it take for absorbable sutures to fully absorb?

• 10 days

• 28 days

• 50 days

• 60 days

Answer explanation

Most absorbable suture materials are fully absorbed in 60-90 days.
