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)
DiabeticContaminated 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 EpinephrineUse UNLESS fingers, toes, penis, or nose (and earlobes)
Marcaine 0.5% (Lasts longer)Sensorcaine 0.5%
Sodium BicarbonateLessens ‘sting’ of LidocaineDo 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)
•Ethilon6-0 Face5-0 Everywhere else
•Prolene6-0 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
