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

Q

Double (Swaged) - Arm:

A

. Needles swaged to each end of the suture
. Used for anastomosis of vessels

29
Q

Needle Points:

A

Are cutting needles used for though tissue like sclera, tendon or skin
Ex.
Conventional, Reverse & Side cutting needles

30
Q

Conventional Cutting Needle:

A

. 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
Q

Reverse Cutting Needle:

A

. Opposing cutting edges in a triangular configuration that extends into the shaft
. Used in the skin results in less tearing of the tissue

32
Q

Side Cutting Needle:

A

. Does not penetrate into deeper tissues
. Used primarily in ophthalmic procedures

33
Q

Tapered Point Needle:

A

. Round shaft without a cutting edge
. Penetrates tissues without cutting it (intestines)

34
Q

Blunt Point Needle:

A

. Round shaft with a blunt tip
. Used for friable tissues (kidney & liver)

35
Q

Taper Cut Needles aka Ground Point Needles:

A

. 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
Q

What is the range of needle length?

A

1/2 to 4 in

37
Q

What is the guage size range of a needle?

38

Q

Order of layer closure for abdominal wounds:

A

Order of layer closure for abdominal wounds:

53
Q

Fast Healing Layer: Abdominal

A

Peritoneum

54
Q

Primary Supportive soft tissue structure: Abdomen

54
Q

Slowest healing layer: Abdominal

55
Q

Muscles

A

. Not typically closed but may be loosely approximated with interrupted absorbable sutures

56
Q

Peritoneum

A

. 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
Q

Fascia

A

. 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
Q

Subcutaneous Tissue:

A

. Placement of few interrupted sutures to prevent dead space
. Plain gut is often used

59
Q

Subcuticular Tissue:

A

. Area of tough connective tissue beneath the skin above the subcutaneous
. Subcuticular closure is used to minimize scaring
. Absorbable sutures are often used

60
Q

Skin Tissue:

A

. Closed with interrupted or continuous monofilament, Nonabsorbable sutures in a cutting needle
. Polypropylene or nylon preferred

61
Q

Primary Suture Line

A
  • Suture that approximate wound edges for first intention healing
  • Interrupted, Continous
62
Q

Continuous or Running Suture

A
  • 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
Q

Interrupted Sutures

A
  • Used in fascia & heart closures
  • Useful in infected wounds, “interrupts the pathway of bacteria”
64
Q

Traction Sutures

A
  • Used to retract a structure that may not be easily retracted with a conventional retractor
65
Q

Purse String Suture

A
  • 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
Q

Subcuticular Suture

A
  • Buried Suture
  • Used for skin closure ONLY
  • Steristrips may be used to reintorce the suture
67
Q

Secondary Suture Line

A
  • Useful for support of the primary suture line
  • Helps ease tension on the primary suture line
68
Q

Retention Sutures

A
  • Large gange, interrote, Non absorbable sutures placed lateral to the primary suture line for wound reinforcement
