basic suturing principles (dm bedah kelompok d by dr. wahyu prabowo s.pb)

Dr. Wahyu Prabowo S.PB

Wound healing and scarsThe goal of optimal wound closure is to

obtain a fine line scar that maintains both the form and appearance of the

tissue. It is important to let your patient know that any time there is an an

incision there is going to be a scar. However with careful technique and

close attention to tissue integrity this scar can be minimized. Know when it is

a closure that you should not attempt e.g. lip, eyelid, across a joint, tendon involved, or the web space of a hand.

Preparation• Plan the incision or type of closure• Gather equipment – irrigation, syringes, anesthetic,

instruments, suture, drapes, dressing.• Time out:

• Check patient name and sign a consent• Check what procedure is to be done

• Scrub glove and drape• Prepare the skin – betadine on the outside • Local anesthetic – lidocaine or bupivacaine• Debridement or incision• Undermining where necessary

Start in the center and swab in circles going outward

finer dissection.Steady the arm by

using the little finger as a fulcrum.

Pass scalpels in a kidney dish.

Never pass it point-first across the table.

AnestheticLidocaine 1% or 2% - inject locally or a regional block

• gives anesthesia and reduces muscle movement

Bupivacaine (Marcaine) 0.25% or 0.5%• gives anesthesia only

lidocaine and bupivacaine can be mixed half and half

Epinephrine can be added to increase anesthetic time and decrease bleeding – don’t not use on fingers, nose, penis or toes

May be buffered - 9:1 with sodium bicarbonate, to reduce pain on injection (e.g. remove 2 mL of 1% lidocaine from 20 mL vial, and add 2 mL of sodium bicarbonate solution to vial)

AnestheticLocal Lidocaine (Xylocaine) 1% or 2%

• Onset: 2 minutes• Duration: 1.5 to 2 hours• Action : anesthesia and reduced muscle movement• Max dose: 4-5 mg/kg to 280-300 mg (14 -15 ml 2%, 28-30 ml 1%)

Lidocaine with Epinephrine 1:100,000 or 1:200,000• Onset: 2 minutes• Duration: 1 – 3 hours• Action : anesthesia and reduced muscle movement• Max dose: 7 mg/kg to 500 mg (25 ml 2%, 50 ml 1%)

Bupivacaine (Marcaine) 0.25%• Onset: 5 minutes• Duration: 2 to 4 hours• Action : anesthesia only• Max dose: 2.5 mg/kg up to 175 mg (50 ml 0.25%, 25 ml 0.5%)

Anesthetic SolutionsLidocaine (Xylocaine®)

Most commonly usedRapid onset Strength: 0.5%, 1.0%,

& 2.0% Maximum dose:

5 mg / kg, or 300 mg

1.0% lidocaine = 1 g lidocaine / 100 cc = 1,000mg/100cc

300 mg = 0.03 liter = 30 ml

Lidocaine (Xylocaine®) with epinephrineVasoconstrictionDecreased bleedingProlongs duration Strength: 0.5% & 1.0%Maximum individual

dose: 7mg/kg, or 500mg

Anesthetic SolutionsCAUTIONS: due to its vasoconstriction

properties never use Lidocaine with epinephrine on: Eyes, Ears, Nose Fingers, ToesPenis, Scrotum

Anesthetic SolutionsBUPIVACAINE (MARCAINE):

Slow onsetLong durationStrength: 0.25%DOSE: maximum individual dose 3mg/kg

Instrument tying

Surgical wound closure guidelines

• Adequate debridement and hemostasis• Atraumatic technique• Alignment with the relaxed skin tension lines• Angle of incision

• Perpendicular to skin surface or slightly undermined

• Angle incisions parallel to hair shafts• Consider area of the body for vascularity and

tension on the wound

Key techniques

• Close dead space under the incision• Close that issue in layers• Carefully align the wound edges• Careful choice of the axis of incision or axis of

closure of the donor skin flaps• Correct choice of deep and cutaneous sutures

Bleeding

• Control with pressure directly over the wound immediately

• Locate the nearest artery and put pressure there to give yourself room to work.

• If necessary tie off the bleeding vessel.

• Use a pressure bandage

Simple Interrupted sutures• This suture is used for simple laceration

closures or closure of office procedures like biopsies or lesion removals.

• It is also the basic suture used inside the wound to close deep sutures.

• It is useful in that a few sutures can be removed at a time instead of all at once to allow for slower sound healing

Continuous Sutures• The continuous suture as its name suggests,

only has a knot at the beginning and the end. • There are several methods of continuous

suture – locking and non-locking.• The knots must be very secure and minimal

tesion on the wound or the wound will come apart if one loop or knot gives way.

• The advantage is that it is very quick and the wound tension is even across the wound.

Horizontal Mattress Suture• Used with wounds with poor circulation• Helps eliminate tension on wound edges• Requires fewer sutures to close a wound • Can be placed quite quickly• Can be done as a continuous suture

Vertical Mattress Sutures• Deep and shallow approximation of the tissue• Can be used for wounds under tension.• Can be useful with lax tissue e.g. elbow and

knee.• Should not be used on volar surface of hands

or feet or on the face because of blind placement of the deep part of the suture.

Sub-cuticular closure• Used for cosmetic closures• Use an absorbable suture if you plan to leave

the sutures in and bury the knots• Use either nylon or prolene (best) and keep

the suture sliding while you are closing. The suture then can be easily removed with no exterior marks. The ends can be taped or a knot on the skin.

• At each entry point, enter across form the last exit with slight overlap.

Eliptical incisionThe ellipse should be three times as long as it is

wide. This will make closure of the wound much easier. If the lesion you are removing is likely to be cancerous, make sure that you leave wide margins of clear skin around the lesion.

3 Cornered Suture• Used to close a skin flap which comes to a point.• Helps close the wound, but maintain circulation

to the tissue.• Places minimal tension on the wound edges
