Should not be used for percutaneous sutures

Back 10

Multifilament

Front 11

Maintains strength temporarily but gradually loses tensile strength

Back 11

Absorbable Sutures

Front 12

Retains tensile strength

Back 12

Non-absorbable Sutures

Front 13

Useful for device fixation, areas of extreme tension, slow healing areas or percutaneous skin sutures

Back 13

Non-absorbable sutures

Front 14

Proteolytic Enzymatic Digestion

Back 14

digestion of natural absorbable sutures by body enzymes with attack and break down the suture

Front 15

Type of absorbable suture broken down by proteolytic enzymatic digestion

Back 15

surgical catgut

Front 16

Hydrolysis

Back 16

Process by which water gradually penetrates the suture filaments, causing the breakdown of the suture's polymer chain

Front 17

5 Types of Needles

Back 29

1. Conventional Cutting Needle
2. Reverse cutting needle
3. Taper needle
4. Taper body needle
5. Spatula Needle

Front 30

skin closure

Back 30

conventional cutting needle

Front 31

tough tissues

Back 31

reverse cutting needle

Front 32

smooth, soft tissue

Back 32

taper needle

Front 33

blunt dissection and friable tissue

Back 33

taper body needle

Front 34

eye surgery

Back 34

spatula needle

Front 35

two successive double throws are useful to prevent slippage

Back 35

Nylon Monofilament Suture

Front 36

needle with the cutting edge on the concave (inner) surface

Back 36

Conventional cutting needles

Front 37

needle with cutting surfaces on the convex (outer) surface

Back 37

Reverse cutting needles

Front 38

The needle has a tapered and no cutting edge; therefore, it is generally used for closing soft tissue such as gastrointestinal, vascular, fascia, and other soft tissue that is found below the skin’s surface.

Back 38

Taper body needle

Front 39

a minute needle with a flat or slightly curved concave surface that does not cut or pierce.

Back 39

Spatula needle

Front 40

Suture Size in order from smallest to largest

Back 40

7-0, 3-0,0, 1, 3, 7, etc.
