Q

Suture Purpose:

A

Wound Closure
*Tissue approximation
–Bringing individual surfaces together (e.g.. skin, fascia)
*Anastomosis
–Joining of tubular structure together (e.g. intestine, blood vessels) by suturing to promote unhindered flow of fluids
–Hemostasis
*Decrease blood loss
*Allow better visualization of the surgical field

24
Closed Eye:
Causes more tissue damage (Ex. Sewing Needle)
25
French Eyed:
. Fast Loading . Causes more tissue damage (v-shaped area above the eye)
26
Swaged (Eyeless)
. Needless are continuous w/ the suture strand or the needle may be detached . Less tissue damage . Detachable needle is referred to as a controlled release
27
Single (Swaged) - Arm
. Single needle is attached to the suture . Used for interrupted or continuous suturing
28
Double (Swaged) - Arm:
. Needles swaged to each end of the suture . Used for anastomosis of vessels
29
Needle Points:
Are cutting needles used for though tissue like sclera, tendon or skin Ex. Conventional, Reverse & Side cutting needles
30
Conventional Cutting Needle:
. 3 cutting edges directed along the inner curve of the needle . Place a small cut in the direction of the pull of the structure
31
Reverse Cutting Needle:
. Opposing cutting edges in a triangular configuration that extends into the shaft . Used in the skin results in less tearing of the tissue
32
Side Cutting Needle:
. Does not penetrate into deeper tissues . Used primarily in ophthalmic procedures
33
Tapered Point Needle:
. Round shaft without a cutting edge . Penetrates tissues without cutting it (intestines)
34
Blunt Point Needle:
. Round shaft with a blunt tip . Used for friable tissues (kidney & liver)
35
Taper Cut Needles aka Ground Point Needles:
. Point with sharp edges but a round body of a tapered needle . Used for graft . Makes smaller holes in the tissue . Primary choice for vascular tissue
36
What is the range of needle length?
1/2 to 4 in
37
What is the guage size range of a needle?
12-30

Order of layer closure for abdominal wounds:
Order of layer closure for abdominal wounds:
53
Fast Healing Layer: Abdominal
Peritoneum
54
Primary Supportive soft tissue structure: Abdomen
Fascia
54
Slowest healing layer: Abdominal
Fascia
55
Muscles
. Not typically closed but may be loosely approximated with interrupted absorbable sutures
56
Peritoneum
. Thin membrane lining the abdominal cavity . Fast healing . May not require suturing if the fascia is closed properly . Continuous 3-0 absorbable suture is frequently used
57
Fascia
. Tough connective tissue covering the muscle; primary supportive soft tissue structure of the abdomen . Heals slowly . Heavy interrupted non absorbable suture is used . Absorbable- slow absorbing & high tensile strength . If facial layer is weak a mesh can be applied
58
Subcutaneous Tissue:
. Placement of few interrupted sutures to prevent dead space . Plain gut is often used
59
Subcuticular Tissue:
. Area of tough connective tissue beneath the skin above the subcutaneous . Subcuticular closure is used to minimize scaring . Absorbable sutures are often used
60
Skin Tissue:
. Closed with interrupted or continuous monofilament, Nonabsorbable sutures in a cutting needle . Polypropylene or nylon preferred
61
Primary Suture Line
- Suture that approximate wound edges for first intention healing - Interrupted, Continous
62
Continuous or Running Suture
- Single strand spure placed na series of sliches for closure - Even distributed tension is the hallmark of mis cosure - Drawback the suture losens fone segment breaks
63
Interrupted Sutures
- Used in fascia & heart closures - Useful in infected wounds, “interrupts the pathway of bacteria”
64
Traction Sutures
- Used to retract a structure that may not be easily retracted with a conventional retractor
65
Purse String Suture
- Drawstring Suture is placed in a circular fashion around a structure in such a way that pulling on the suture tightens & closes an opening such as the appendix
66
Subcuticular Suture
- Buried Suture - Used for skin closure ONLY - Steristrips may be used to reintorce the suture
67
Secondary Suture Line
- Useful for support of the primary suture line - Helps ease tension on the primary suture line
68
Retention Sutures
- Large gange, interrote, Non absorbable sutures placed lateral to the primary suture line for wound reinforcement
