The 8 aspects of plastic surgery

The 8 Aspects of Plastic Surgery

  • Congenital: clefts, nevi, vascular tumors

    ear reconstruction, hand anomalies

  • Hand: nerve compression, tumors/soft tissue, trauma

  • Head and Neck:resection and reconstructivesurgery

  • Skin cancer: excision and reconstruction

  • Burn Reconstruction

  • General Reconstruction: truck, abdomen, lower limb

  • Breast: reduction, reconstruction

  • Cosmetic


2 ways to get in trouble in medicine

2 ways to get in trouble in medicine

  • DON’T GO WHEN YOU ARE CALLED

  • DON’T CALL WHEN YOU GET THERE


Gorney s rule

Gorney’s Rule

  • Extent of problem should = the concern

  • Operate on ‘ Sylvia ’ : secure, young, listens, verbal,intelligent, attractive

  • Don’t operate on ‘Simon’: single, insecure, male, overexpectent, narcissistic


Post operative complications

Post operative complications

  • 5.4% complication rate clean surgery cases : 50% preventable

  • Blue Cross Aneheim refuses to pay for complications: April 2008

  • Specifically: pressure sores, sternal wounds, line/foley sepsis

  • Record insurance profits 2007: aggressive disclaimer policies

  • Post op infection most frequent complication: 1/2 mil/yr USA

  • Average cost per infection is $3,000

  • Post operative infections associated: 2 x procedure mortality


What stops wound healing

What stops wound healing

  • Infection

  • Foreign body

  • Tension/reduced vascularity: venous,arterial,both

  • Inflammation: allergic, autoimmune, mechanical

  • Steroids and cytotoxic agents

  • Tumors

  • Munchausen’s Syndrome


Controlling surgical site infections

Controlling Surgical Site Infections

  • Saline versus water irrigation similar infections rates

  • Transfusion during cardiac surgery increases rate

  • Supplemental hydration does not change rate

  • Hypothermia core temp< 36 C (96.8)

  • Prophylactic antibiotics < one hour before incision

  • One dose IV as good as multiple & less C diff later

  • Cardiac patient glucose control < 200 mg/dl

  • Best no hair removal < shave < razor

  • Maintaining oxygenation

  • Maintaining arterial, venous and capillary circulation


Hypothermia and wound infection

Hypothermia and wound infection

  • 200 pts undergoing colorectal surgery: hypothermia assoc with 19% infection rate, vrs 6% non hypothermia

    Kurz, et al, 1996: NEJM 334(19):1209-1215

  • Hypothermia leads to vasoconstriction

  • Vasoconstriction reduces tissue partial pressure O2

  • Tissue hypoxygenation = decreased neutrophil phagocytosis

  • Every drop of 1.5 C assoc. complications cost $ 2,500-7,000

  • Influenced by warming: preop pt, fluids, bed, irrigations, room temp, length of procedure, body surface area exposed, inhalation gases


Patterns of blood supply

Patterns of blood supply

  • Random (2:1 ratio)

  • Axial

  • Random and Axial

    ( rectus: type 3 )


Tension compression

Tension / Compression

  • Venous: decreased cap refill: < 3 seconds

  • Arterial: increased cap refill: > 5 seconds

    or no refill: > 5 seconds

  • Creep phenomenon: 3 x 1 minute stretches 3 minutes apart

  • Cyanosis: requires O2 sat of <80% and 2.38 g/deoxyhemoglobin

    not present if arterial ischemia/vasoconstriction or severe anemia

  • Clinical Signs of PE


Dvt preventive stockings

DVT Preventive Stockings

  • Reduce post-MI DVT p<0.003 (Kier,1993:Eur Heart J 14,1365-68.)

  • May be as effective as pneumatic compression or low dose heparin

  • Standing position ankle vein pressure in 5´7˝ adult is 86mmHg

  • 20-30 mmHg if standing ineffective at compressing s/d leg veins

  • 4 classes: 20-30,30-40,40-50 & 50-60 mmHg

  • 2 categories: ready made and custom

  • 2 broad types: elastmeric ( day time ), non-elastameric ( straps )

  • Compression garments > 22mm Hg can cause thrombosis: knee

  • elastomerics: woven:excellent, expensive, strong 3 knitted: circular, flat (custom), cut & sew(custom)

    elasticity from synthetic rubber or latex weave

    breathability related to thickness and cotton/nylon


Manufacturers

Pierre Robin

Crouzon’s

Apert’s

Stickler

Klippel Feil

Velocardiofacial


Cleft palate airway obstruction

Cleft Palate & Airway Obstruction

  • Repair separates oropharynx from nasopharynx

  • Compensatory tongue hypertrophy

  • Separation can lead to crowding of orophrynx

  • Microgenia/midfacial retrusion increase crowding

  • IV steroids lead to reduced hospitalization

  • Tongue suture always placed for airway control


Hand surgery

Hand Surgery

  • Allen’s Test

  • Cap refill

  • Elevation

  • Surgical positioning:

    ulnar nerve and

    median nerve compression,

    brachial nerve plexopathy


Capillary refill

Capillary Refill

  • Normal Tissue Capillary Refill is 3-5 seconds

  • Nail Capillary Refill test is < 2 seconds

  • Unreliable in presence of hypothermia and severe anemia


Allen s test

Allen’s Test

Dominant Ulnar > Radial Artery 8.1%

May be higher in populations with h/o ABG’s

1. Elevate hand 30 seconds

2. Make fist elevated

3. Apply pressure over Radial and Ulnar Arteries

4. Open hand while elevated, it should be blanched

5. Release one vessel pressure, should refill in 7 seconds


Median neuropathy

Median Neuropathy

  • Motor: thumb opposition and abduction

    radial 2 lumbricals

  • Sensory: radial 3 1/2 fingers


Rex moulton barrett md plastic reconstructive surgery san leandro surgery center

Ulnar Neuropathy

  • Motor: All intrinsics except thumb opposition & abduction

    radial 2 lumbricals

  • Sensory: Ulnar 1 1/2 sensory


Brachial plexopathy

Brachial Plexopathy

  • poor positioning

  • downward brachial traction

  • shoulder hyperextension

  • descent of the thorax

  • prolonged arm abduction

  • responds to IV steroids

  • true neuropraxia: up to 6 week recovery


Cosmetic abdominoplasty

Cosmetic: Abdominoplasty

  • Not panniculectomy, umbilicus preserved

  • Modern technique utilises low incision

  • Corsetting rectus and oblique muscles

  • Closure in jack- knife sitting position

  • Complications mostly related to tension

  • DVT/PE increased risk if:

    obese, concomitant hysterectomy, liposuction

  • Atelectasis risk when combined breast surgery

  • Commonest cause of SOB: too tight dressings

  • Muscle relaxants, firm abdominal binders and jack=knife positioning in a surgical bed reduce pain


Facelift

Facelift

  • 3 component surgery: muscle, fat, skin

  • Swelling and bleeding very individual

  • Skin survives on random pattern blood supply: tension and smoking can kill (15% smoker slough )

  • Unilateral swelling and pain = hematoma

  • Bilateral tightness in the neck associated with platysma corsetting

  • Relative emergency for skin survival and potential airway compression


Eyelid surgery

Eyelid Surgery

From Rees, 1996

  • Contents within orbital septum closed space

  • Ophthalmic vein, nerve and artery contained within the orbital septum

  • Bleeding after surgery is an absolute emergency, loss of vision can occur within 20 minutes ( 1:20,000 )

  • Release sutures and or lateral canthotomy


Liposuction

Liposuction

  • Traditional, wet, superwet and tumescent

  • Calculation of blood loss

  • Calculation of fluid resusitation

  • Admission to hospital > 6 hours, > 6 litres


Liposuction and fluid rescusitation

Liposuction and fluid rescusitation

  • Traditional 150ml aspirate=drop 1% Hct

  • ie > 2 L needs transfusion

  • IV replacement cc for cc in OR, + cc/cc RR

  • Tumescent: 1 L RL+ 1 cc 1:1,000 epi+ 50cc 1% lido 2 ml in then > 10 minutes 1 cc asp. out,

    Up to 6 L no X match required

    can use up to 35mg/kg: lido in fat

    replace cc/cc in OR, or less

  • Cranberry drainage from the ports for 3 days


Breast augmentation mastopexy

Breast Augmentation +/- Mastopexy

  • Dressings designed to push implants down

  • Commonest cause of SOB: dressings too tight

  • Implants over the muscle hurt much less

  • Muscle relaxants reduce pain, mostly pectoral pain

  • Unilateral chest pain & no swelling:pneumothorax ?

  • Unilateral pain and swelling: hematoma ?

  • Bilateral pain: tight dressings &/or muscle spasm ?


Post bariatic surgery

Post - Bariatic Surgery

  • Risk of bariatric surgery assoc BMI

  • Calculation BSA=(height cms x weight kg/3600)/2 M2

    BMI=weight kg/M2 height

  • Procedures after: abdominoplasty

    circumferential lipectomy

    extended thighplasty

    brachyplasty

    mastopexy/augmentation

    facelift and eyelid surgery

Clinical test case 6

Clinical Test case 6

  • 3 hours after abdominoplasty a 66 yr old previously hypertensive, post bariatric patient with a history of severe lumbosacral back DJD needs high doses of PCA meds to control her abdominal dyscomfort. 5 hours after surgery her BP drops to 70/50 and she becomes drousy with shallow respirations and pin point pupils


Clinical test 7

Clinical Test 7

  • A demanding 63 yr old lady undergoes an uneventful facelift and 6 hours after surgery requests IV MS just 1 hour after her last pain medication because of increased right sided facial pain.
