Avoid infection Hemostasis Esthetically Pleasing Scar T ISSUE L - - PowerPoint PPT Presentation

2018 NPO EDUCATION CONFERENCE

BEGINNING SUTURING WORKSHOP

Mary Fey, FNP

• Avoid infection
• Hemostasis
• Esthetically Pleasing Scar

GOALS OF WOUND MANAGEMENT

Epidermis Dermis

• indistinguishable from each other visibly

Subcutaneous Layer

• Adipose, nerve fibers, blood vessels, hair

follicles Deep Fascia

• Muscle

TISSUE LAYERS

Coagulation begins immediately

• vasospasm, platelet aggregation, fibrous clot formation

Epitheliazation occurs in epidermis

• complete bridging of wound occurs in 48 hours

New blood vessel growth peaks 4 days after injury Collagen formation begins 48 hours, peaks first week, continues 12 months Wound contraction occurs 3-4 days after injury

• full wound thickness moves toward center of wound

MECHANISM OF WOUND HEALING

• Mechanism of Injury
• Age of Injury
• Possible contamination or foreign body
• Extent of the wound
• Neurovascular Compromise or tendon injury
• Need for Tetanus prophylaxis
• Risk factors that might affect healing, i.e.

Diabetes, immunocompromised

WOUND ASSESSMENT

• Animal Bites
• Deep puncture Wounds
• Actively bleeding (arterial)
• Stained wounds (Grease)

CONTRAINDICATIONS OF CLOSURE

Preferably within 6 hours Up to 18 hours if no concerns of infection (High Risk) Diabetic Contaminated Wound May need to debride edges if greater than 6 hours

TIMING OF CLOSURE

Clean and/or Irrigate

• Normal Saline
• Surfactant Cleaners (ShurClens)

Debridement WOUND PREPARATION

ANESTHESIA

Lidocaine 1% Use when need large amount Lidocaine2% Most common Lidocaine 2% plus Epinephrine Use UNLESS fingers, toes, penis, or nose (and earlobes) Marcaine 0.5% (Lasts longer) Sensorcaine 0.5% Sodium Bicarbonate Lessens ‘sting’ of Lidocaine Do not use with Marcaine or Sensorcaine (precipitates)

EQUIPMENT

• Needle Holder
• Tissue Forcep
• Iris Scissors
• Face Shield
• 3 cc Syringe with 25-30 g. needle

Dermal Suture Material:

• Needles (3/8 circle most common)
• Ethilon

6-0 Face 5-0 Everywhere else

• Prolene

6-0 Face

COMMON SUTURE MATERIALS

Most Common and Recommended

• Evert edges of wound
• Penetrate skin surface at 90 degree angle
• Loop same distance at skin and base of wound
• Start in center
• Equal amount of sutures on both sides

INTERRUPTED SUTURE

CORRECT VS. INCORRECT

Useful for closing punch biopsy and very small laceration

SUTURE REMOVAL

• Face/neck

3-5 days

• Scalp

7-10 days

• Trunk

7-10 days

• Joints

10-14 days

• Back/Foot

10-14 days

Great for Scalp Wounds Good for Tension Wounds (Knee laceration) Start at one end and advance to other end May be able to apply with just local anesthetic if only 1-2 staples – Good for someone who is having high anxiety

STAPLES

STAPLE TECHNIQUE

DERMABOND

• Useful for small clean wounds

CORNER STITCH “BOAT IN THE DOCK”

• Start suture in epidermis across from flap
• Insert needle into dermis only and come out in

dermis

• Assure you have a ‘good bite’
• Exit through dermis very near insertion point
• Apply sufficient tension to pull flap into corner
• Tie knot across from corner of flap

CORNER STITCH HALF-BURIED HORIZONTAL
